Hose assembly failure analysis

1, symptoms: hose inner tube is very hard, has been cracking.
   Analysis: temperature of the inner tube is easily precipitated plasticizer, which is a flexible hose can be a plastic material. Entrained gas oil oxidation allows the inner tube. Occur in the rubber products such oxidation reactions can be cured. Oxygen and temperature, will greatly accelerate the hardening of the hose tube. Occurred inside the inner tube cavitation also have the same effect.
2, symptoms: hose cracking internally and externally, but the elastic material is still soft at room temperature deflectable.
   Analysis: The likely reason is that the hose when the ambient temperature is very low deflection. Most standard hose is rated to -40 degrees, and some AQP hose rated temperature is -49 degrees, usually military hose rated temperature is -54 degrees, and some thermoplastic hose rated temperature is -54 degrees, poly four vinyl fluoride hose rated temperature is -73 degrees.
3, symptoms: hose rupture, hydraulic tube fittings peel the outer layer of wire reinforced rubber examination found that the entire length of the hose irregular wire breakage.
   Analysis: This indicates the pressure of the hose in a highly frequent fluctuations. SAE American Automobile Association, the two-story steel braided hose impact testing required at 133% of the recommended operating pressure of up to 200 000 cycles. About four-spiral hose SAE impact test requirements of up to 500 000 cycles. If the number of pulses within the extrapolation in a short time, more than one million times, the best choice for the enhancement layer wound hose.
4, symptoms: hose rupture, but not displayed on the entire length of the hose with multiple wire breakage. hydraulic hose sleeve May be more than one hose rupture.
   Analysis: This indicates that the pressure has exceeded the minimum burst strength of the hose. Recommended to use higher-strength hose, or hydraulic lines appear abnormally high pressure conditions can cause malfunction.

Power adapter market trend analysis

Power adapter market is an important trend is the customer needs to have a higher output power, smaller size of the adapter , which involves the use of a new topology . Power Adapter mainly reflects some important trends . First, the work efficiency and standby ( no-load ) energy demanding. For example, the U.S. Environmental Protection Agency (EPA) " Energy Star" program in April 2008 released a version 2.0 of the external power supply specifications for external power supply EPA2.0 this version of the spec will be held November 1, 2008 came into effect. Power adapter includes two categories, one is the internal AC / DC (AC / DC) power converter, built- in electronic products internally and may possess multiple output voltages , such as a desktop computer's internal power supply, etc. ; reusable fitting the other is the external one-way output AC / DC or AC / AC (AC / AC) power adapter with single output voltage, typically referred to as an external power supply (EPS), widely used in printers , laptops , LCD monitors and gaming applications. In addition to the "Energy Star " kind of industry energy efficiency specifications, some large OEM customers may also have their own unique work of energy efficiency and energy requirements . For example, for computer power EPA4.0 norms for the use of an external power supply laptop and tablet PC requirements are primarily reflected in the standby power consumption (≤ 1.0W), dormant energy consumption (≤ 1.7W) , etc. ; comparison, Dell power requirements for this type of mainly reflected in the different load conditions specific energy efficiency , ie 0.7W ( input power Pin <1W), 1.5W (Pin <2W), 10.7W (Pin <12.6W) and 17W (Pin <20W) load conditions, can be respectively more than 70% efficiency , 75% , 85% and 85%. It is worth mentioning is that the future will continue to regulate the energy efficiency requirements continuously improve and evolve . With laptop AC-DC power adapter , for example, the industry in no-load mode, a high level of energy consumption is about more than 300mW , 150mW and future load mode energy consumption could become targets. Moreover, the requirement for multi-output adapter may also be included among the criteria . ON Semiconductor 's NCP1605 power factor correction (PFC) controller and NCP1396 resonant mode controller can be used to design 200W or 300W Desktop Adapter adapter. hydraulic hose adapters From the notebook adapter , its power requirements from 50W to 70W range has been increased to more than 100W rating. In addition, such as Apple and Lenovo ThinkPadX300 MacBookAir other new ultra- portable notebook power adapter is also smaller and lighter.

Corrugated metal hose technology history

  Since 1855, German inventor and manufacturer of the world's first one corrugated metal hose since, after one hundred years of development, its reliable sealing metal hose , pressure resistance , high temperature resistance , corrosion resistance and flexible , and many other properties, widely used in aviation, aerospace, nuclear energy , shipbuilding and new construction and other industrial sectors , a modern piping systems essential components. With the rapid development of modern industry , metal hose is used widely for metal hose requirements are also increasing, bound to the metal hose technology more and more research , the development of metal hoses generally have the following stages :
      Initially , people used animal skins sewn into a tubular structure to meet the needs of the struggle for production . After a fairly long period , to 70 end of the century , the Dutch Golden Gai Wan del brothers made ​​a longitudinal suture canvas hose , at the time of the fire service is widely used . Later, with the rubber in the international market and the emergence of vulcanization process of development, hoses and metal wire or twine and other fabrics Kai mounted hose come out. But the works of some steam , hot air type high temperature medium ; liquid hydrogen ,socketless fitting liquid oxygen, liquid helium cryogenic medium class ; gasoline, kerosene, acid , alkali and other corrosive media ...... If the hose to transport , of course not. Especially at high temperatures, it is more difficult to ensure the security and reliability .
      Therefore, it gradually to focus on the metal tube , the metal tube geometry to produce the corresponding corrugated external surface . In this way, both with the same flexibility with hose : but also has a high temperature, low temperature resistance , aging resistance, corrosion resistance. Thus, as the metal hose body metal bellows thus produced .
     1855 , first published in Germany in manufacturing bellows patents. It is used when making jewelry has some principles to manufacture bellows . 30 years later, the French and German cooperation in the development of new metal bellows , in August 1885 won the French and German patents.
     l894 , the kind of bellows structure has been improved : People metal band by using two different diameter, wound in the opposite direction . Thus, the stress state of the metal strip in the lower reaches equilibrium with each other to overcome the shortcomings of the spontaneous unfolding .
    In 1929, the structure of the bellows had another technological revolution , which completely solved the bellows filled pad due to bending when asbestos rope rubber band or changes in the grooves of uneven sealing performance loss problems , thus opening up a corrugated tube broad prospects for development .
    From the 1950s began , double, triple , multi-layered bellows. Especially very thin-walled stainless steel bellows developed rapidly . In order to meet the requirements , banjo fitting it is welded , electroforming , machining, hydraulic and mechanical spinning process method to manufacture a variety of bellows .
    Corrugated metal hose from the tube as the significance of the body in terms of the development of metal bellows , metal hose means development .

Hydraulic pipe installation should pay attention to several issues

Hydraulic Pipe installation must note the following:
One should be based on the hydraulic system pressure, flow, working medium, the right to use the environment and hydraulic components and fittings requirements, selection of appropriate diameter, wall thickness and material of the pipeline.
(2) should be considered in the pipeline piping neat appearance and easy maintenance. Preferably arranged in parallel lines, less cross. Parallel or crossover between the tubes should be at least 10mm clearance to prevent contact between china hydraulic hose the pipe and vibration, and fittings to install sufficient space.
3 tube length should be as short as possible, thus reducing the pressure loss and delay and vibration phenomena.
4 the pipe bend radius R of the center line and outside usually determined to be greater than three times the diameter of the tube. Also take a large diameter hours.
5 In the Configure piping system, the force of the pipe to prevent sagging and vibration, you must set pipe supports and pipe clamp the pipe to the bracket. Distance between supports varies with pipe diameter, generally selected within 0.4 ~ 1mm.

Electro-hydraulic block brake - Introduction

China CNC cutting machine transition from extensive to intensive management

China CNC cutting machine transition from extensive to intensive management
Although China's CNC cutting machine start over, but by the downstream machinery processing and other related industries, demand for support, the rapid development of the industry as a whole, the scale is also growing. But

For now, although the strength of many companies has improved, but still in the extensive type of business model. Due to excessive competition, product homogeneity serious, resulting in profits empty

Cramped, but also to the development of many companies fettered.

Price competition in teflon hose the adverse market environment, a large number of domestic manufacturers and brands is not prominent, the lack of technological innovation, heavily dependent on foreign advanced technology, lack of core

Competitiveness. Meanwhile, rising labor costs, coupled with the rise in raw materials also greatly increased the number of corporate cost pressures. From the above phenomena can be predicted, intensive hair

Exhibition mode will certainly be a lot of CNC cutting machine tool enterprises in the future development direction.

Transition from extensive to intensive, low-technology that is changing the content, low management level, low-cost-effective manner, to the high-tech, high capital levels,

High level of management, high economic quality, high cost of operation.

A CNC cutting machine tool industry demand "strength training"

Walking intensive development path, you first need to do is to change their concepts, and establish long-term development of the concept and to develop a viable goals and plans.

Meanwhile, CNC cutting machine tools companies need to come out from the price competition, steering practicing internal strength. "Focuses on the optimization of product structure, product quality improvement, the core technology

Technique mastery and innovation, and the growing influence of corporate brand. Of course, this series of shift requires more capital investment enterprises, which, CNC cutting machine tool enterprises

Industry also needs according to their own circumstances, input-output ratio in the future to make a scientific estimate, so as to selectively invest for a gradual transition.

Second, multiple channels to improve operational efficiency

Intensive management in order to improve efficiency as the ultimate goal, take intensive development path, be sure would like to "low-input, high-yield" business goals, which requires NC

Cutting machine tool companies from many aspects change is undertaken.

On the one hand, companies need to constantly improve enterprise management level, to improve the overall performance management, optimize departmental structure, human resources and avoid waste of time,

While optimizing internal competition mechanism, improve the professional quality of employees.

On the other hand, CNC cutting machine tool enterprises may wish to try high-tech business, to develop computer network engineering, office tools through improved operational efficiency and enhance

.

Third, the development socketless fitting of CNC cutting machine tool enterprises centralization

Strengthen the supply chain upstream and downstream enterprises with close ties to form a strong competitive centralized district of CNC cutting machine, CNC cutting machine for some merchants

And enterprises, enhance their competitiveness and expand market share, has important significance.

Good industrial plan to promote industrial upgrading

CO2 laser cutting machine with fiber laser cutting machine comparison

CO2 laser cutting machine with fiber laser cutting machine comparison
From the modern laser cutting, welding machine applications and the technical requirements of the user point of view, laser cutting, welding is undoubtedly the future direction of development of high power, large format

, High efficiency, a molding, high intelligence.
HGLaser Fali Lai has been committed to high power laser and plasma technology applications. The primary focus here is CO2 and fiber laser cutting machine laser cutting machine processing

The difference:
First, as the mainstream of traditional laser cutting, welding equipment are used CO2 laser, can be stabilized teflon hose within 20mm cutting carbon steel, 10mm stainless steel within, 8mm

The following aluminum alloys. Fiber laser cutting of thin plate 4mm or less obvious advantages, by the impact of solid-state laser wavelength when it is of poor quality in the cutting plate. Laser cutting

Cutting machine is not a panacea, CO2 laser wavelength of 10.6um, solid state lasers such as YAG or fiber laser has a wavelength of 1.06um, the former is more likely to be non-metallic

Absorption can be high quality for cutting wood, acrylic, PP, glass and other non-metallic materials, which are not easily absorbed non-metallic, non-metallic materials, it can not be cut

However, when confronted with two lasers copper, silver, aluminum high reflective materials when they do nothing.
Secondly, because of both the CO2 and fiber laser wavelength difference of one order of magnitude, the former can not be used in optical fiber transmission, optical fiber transmission which can be used, greatly increasing the

The degree of processing flexibility. Early in the fiber laser market before, in order to achieve three-dimensional processing, we use highly sophisticated optical technology through the joint action with the

States combined CO2 laser reflector system will lead to a three-dimensional surface surface to achieve a three-dimensional CO2 laser machining, precision machining of this technology because of the technical limitations of domestic primary

Rests in the hands of very few European and American countries, expensive, high maintenance requirements, the fiber laser market share gradually expanding at the same time has been gradually losing its market.

The fiber laser because it can be transmitted through the fiber, the degree of flexibility than ever before, especially for the automotive industry, because basically about 1mm thin surface

Processing, fiber laser with the same flexible robotic systems, low cost, less point of failure, easy maintenance, fast and doing my part to firmly occupied this city

Field.
Again, the fiber laser photoelectric conversion rate of up to 25%, while the CO2 laser photoelectric conversion rate of only about 10% in electricity consumption, cooling systems and other aspects of supporting light

Advantages of fiber lasers is fairly obvious, if the fiber laser manufacturers some more, and then right price point, and solve the plate cutting process, CO2 laser subjected

Threat will be large. However, socketless fitting the fiber laser as a new laser technology, penetration is far less CO2 laser, its stability and reliability, after-sales service

Convenience market's long-term remains to be seen.
It is worth mentioning that, according to international safety standards, hazard rating of 4 laser, CO2 laser is the least harmful one, while the fiber laser wave length due to the human body by the

So great damage to the eyes, are the most harmful one, for security reasons, fiber laser processing needs fully enclosed environment.
In addition, the fiber laser with a robotic flexible manufacturing systems in the automotive industry and supporting industries, high-status a long time, used to be monopolized by foreign integrators, nearly

Years as the financial crisis and the automotive industry production technology continues to improve, especially in the domestic high-end manufacturers such as laser technology HGLaser Fali Lai in support of national policy

On technology research, many foreign car brands and high-end national brand gleaned crabs, the share of foreign high price arrogant and secretive veil has been lifted, tearing, laborers

Laser Farleylaserlab car users in recent years to provide automotive BIW welding, laser weakening car dashboard, airbag laser welding, car bumpers, car

Doors, columns and other robots in flexible cutting, laser welding car bumpers, car exhaust pipe line welding system, car gearshift sleeve automatic laser cutting equipment, etc., in a

Households live 24 hours a stable and efficient production, allowing users praised the laborers Fali Lai also let foreign integrators shouted, "wolf"!
In summary, laser applications should be directed towards the application of high-power CO2 laser in a more stable, more large-format, faster machine. 2mm below the surface for processing

Fiber laser is an advantage.

Material selection hydraulic hose protective sleeve material is generally used in the processing of nylon, polyethylene, polypropylene, etc.
Hydraulic hose protection sleeve - Product Overview
Hydraulic hose protection sleeve is an alternative to traditional metal protection hose protection hydraulic flanges spring of new products. Hydraulic hose protection sleeve commonly used material made of nylon or polypropylene. Corresponding hydraulic hose protection sleeve with traditional metal retaining spring products have good wear resistance, anti-aging, corrosion resistance can be strong; more potent anti-aging on the outer surface of the hose and anti-friction protection. Hydraulic hose protection sleeve relative to the hose retaining spring jacket products and other products with superior convenience and environmentally friendly energy-saving effect. Hydraulic protective pouches generally planar surface, the outer surface of plane and cambered two kinds.

Production equipment: hydraulic hose protection sets of production equipment including plastic extruder, sheath wrapping machine, autoclave and so on.
Hydraulic hose protection sleeve - Production
Hydraulic hose protection sleeve is used in the production of heat-setting process, the general shape of a shape and the secondary processing of two kinds.

Time setting process: reusable fitting nylon or plastic granular material by heating the plastic extruder plastics extrusion into sheets and strip, strip from the nose after extrusion die without water cooling that is wound onto the winding machine with different specifications mandrel holder and then cooled by the cooling water after setting off a spiral mandrel that is molded into a jacket.

Secondary molding process: nylon or plastic particles through a thin strip extruder after entering the cooling water; long after cooling and then the winding machine to different specifications wound on a mandrel; then push the mandrel into the autoclave heat curing. After a certain time of the tank, can be formed from the mandrel.

hydraulic hose reinforcing material, which has several

Hydraulic hose fittings, currently used and is studying the skeleton data to develop inclusive of cotton, nylon, high-strength steel wire, flax, linen, polyester, glass fibers, asbestos and carbon fiber, rayon and polypropylene, convention, from Select strengthen these categories data, as a decisive factor in voltage grade.

        When dealing with those hose adapters more special fabrics such as polyester and polypropylene, it is necessary very careful to assure precise heat setting level, or when the onset of vulcanized rubber hose should not have deformed.

        In the use of polypropylene, it is necessary to think about curing temperature carefully. Degrees premise, since in many places, this temperature is very close to the softening point of the substrate. When using this type of yarn or fabric, special adhesive system is also required in order to guarantee the hose and components with plenty of well-organized and the Heart of the bonding results.

        Glass fibers and asbestos fibers have been used for steam hose and other heat-resistant hose. Of course, the wire is also used for such use.

        The presentation of a new carbon fiber gum gum category can be used, but the current cost of this new information is high. Therefore, in addition to over the coming years in the space outside the scope does not extend to use; and carbon fiber on which points are worth noting: For tensile strength as compared to the carbon fiber reinforced fiberglass difference information with little or no two who has a high tensile and low density values ​​- equivalent to 25% of steel, however. great benefit of the use of carbon fibers reinforced with such media is high strength steel having a large data five or six times greater than the glass fiber characteristic modulo value, characterized in modulus can be used as a measure of tensile load, which can support the specific component of the beam and not flat clothes, thus. subsequent carbon fiber tends to be used for the reinforcement of metals and ceramics, and not as normal that the pure fiber data: it is Christ in the rubber industry can be very useful in the manufacture of fittings and hydraulic system dynamic sealing,

        Another high-strength, high cost fibers are chemically aromatic amine polyphenol family, a member of the demand is high strength, excellent heat and chemical resistance of places, with it specifically useful. The usefulness of the system include hose: Heavy launch machine (such as persistent heavy-duty engine and diesel engine vehicles convergence refrigeration and heat pipe) and subsea wells seawater for use on equipment-based high-pressure hose and so on.

65, mining machine fabric hose should pay attention to what?

From an opening, you use machinery and to improve their quality of life and a perfect mission effectiveness.teflon hose  Mainly hydraulic hose industry significantly affected, forever altered the appearance of human machinery. Hydraulic hose system, relying on high-pressure liquid power of money, cloth hose in order to implement its instinctive drive. This liquid purity is to shut the main form so that it can carry out its objectives, which means to go through the operation of petroleum distillation system hydraulic hose liquid filtration lost any impurities.

       In ancient times the motor cylinder and complicated varieties, will transfer cylinder and motor oil through the control valve hydraulic hose, hose, tubing. In our daily use for performing the main instinctive function, so a lot of mechanical hydraulic hose systems function in their use. Bulldozers, classified as reptiles, rigid plates move applications to participate in another set of each wheel, the use of the continuation of the track. Continue to track the activities of this goal is distributed over a larger surface of the wheel will be removed from pure mechanical quality. Bulldozer equipped with a dozer blade. "

       Bulldozer, even for a long time assigned to various types of machinery, accurate use of terminology to describe a dozer a persistent drive.

      This blade is the application of moving debris, sand and dirt, especially in the establishment of the task. In the first bulldozer, its blade brake, or a winch system moderation. They are currently equipped with a hydraulic cylinder, and promised a finer blade operation. Another exercise its function of hydraulic hose pieces are mechanical excavators. It is a commonly known as the excavation excavator stuff.

       Metal hose which in essence is a persistent machine, equipped with a hinged arm excavation program, the final one bucket. This is the closest to the vehicle's arm is called prosperity, another part is the arm scoop. Bucket and arm, accurate and highly complex activities thriving hydraulic hose momentum.

      Forklift hydraulic hose systems, and power supply. This mechanical lifting and transporting heavy goods, especially in mobile and landing pallet in the warehouse and distribution center inventory using industrial trucks. Forklift mast is progress and reduce the load performed most of the tasks.
