High pressure hydraulic hose assembly

We are engaged in providing a range of high pressure hydraulic hose assembly which uses high-quality synthetic inner, outer cover, has a good stretch silk and rayon made of steel. These single wire braided hydraulic hose ideal for use in various industries, including automotive, industrial, medical and aerospace industries. This is considered an effective way to convey a fluid under pressure.
As a result of high tensile steel wire, single wire braided hydraulic hose is workable to support specified working pressure. For this reason, it is not necessary to employ double wire braid hose. However, when the working environments are abrasive and corrosive, two braided hydraulic hose is a better alternative. The extra braid protects interior rubber and greatly extends hose service life.

Hydraulic Hose better knowledge

Ningbo PH Machinery Factory Co., Ltd. Parher has grown up into a leading hydraulic hose machine in China. With the continuous economic development, hydraulic hoses have been extensively used in industries, mines, steel works and chemical factories. Compared to rigid pipes, hydraulic rubber hose can bend to specified radius and resist vibration damage.
Our factory has introduced advanced hose making machinery and production process to improve hose quality and satisfy customer's stringent requirements. In recent years, we've exported to many countries including America, Britain, France, German, East Asia and other countries.

Hydraulic Hose

Adout single wire braid hose safety

When the One wire ferrule cannot provide a measure of safety then a second layer of wire braiding is added. And there are two reasons to consider for this: the extra wire provides for higher working pressure, and the interior braid is still protected if the hose cover has been damaged and the exterior braid may rust and fail. This is an important consideration where hoses are subject to external damage and then left out in the weather (for example the farm machinery). Double wire braided hydraulic hose is widely used in the daily life and industry because of its features of moderate price, large scope of applications and providing of a measure of safety.

wire braided hydraulic hose can be divided into many types

wire braided hydraulic hose can be divided into many types according to the layer number. Here we will introduce two kinds of wire braid hydraulic hoses that are widely used in the markets. They are namely single wire braid hose and double wire braided hose.
Steel wire braided hoses can be used to transport petrochemicals and hydraulic fluids under relatively high pressures and temperatures. In addition, oil-resistant wire braided hoses can provide flexible connections between steel pipes in hydraulic machines systems. They can find their applications in the fields of mine hydraulic bracket, automatic hydraulic systems of oil field exploiting machine, mine projects and other industrial sectors, especially used as jackhammer component. It can withstand in the temperature of -40°C to +100°C, and the maximum temperature can be +125°C. Also the surface of steel wire braided hydraulic hose can be two types including smooth and fabric surface.

Hydraulic adaptors (hydraulic pressure allocator)

Hydraulic adaptors (hydraulic pressure allocator) is widely used in engineering machinery, agricultural machinery, hydraulic system control, mainly by the control valve opens and closes to control the flow of hydraulic fluid to control

the direction of the hydraulic cylinder mechanical action.
The main sub-manual control, electric control and pressure control and other types. Most of the domestic agricultural manual control and mechanical control distributor, imported mostly large-scale agricultural and excavators electric control distributor.
American hose fittings is manually distributor of automotive control valve.

(7) hose during storage generally should not exceed two years, and should be used before storage, first use, to prevent prolonged storage affect the quality of the hose.

Hose transportation

hydraulic hose during loading and unloading, should pay attention to the following points
hose fittings during loading and unloading, to do Handle gently.
Hose reel need Classification (article) neat shipment, to avoid excessive bending of the tube discounts, and should not be on the heap pressure hose other heavy objects.
Prohibited the hose with acids, alkalis, oils and organic solvents, flammable and explosive materials mixed; tube should not be in direct contact with the sharp edge of the cargo.
For straight transport hose required when length exceeds the load compartment, the long part should support bracket to prevent damage to the hose on the ground mop.
If for any reason need to hose temporarily parked in the open air (or workshop Pier), the site must be flat, flat hose should be neat, and do underlay cover, do not stack ballast; at the same time, the hose is not in contact with the heat source.
When transporting hose should not drag anywhere on the heavy hose lifting equipment should be used special equipment or handling and to prevent the hose from accidental damage.

Hydraulic working medium

Acting hydraulic machines used for working medium not only to pass the pressure, but also to ensure the machine working parts work is sensitive, reliable, long life and low leakage. Hydraulic basic requirements for working medium are: ① have appropriate liquidity and low compressibility in order to improve the efficiency of the transmission; ② can prevent corrosion; ③ good lubricating properties; ④ easy to seal; ⑤ stable performance, long-term work without deterioration. hydraulic machines with water as the working medium initially, after the switch in water by adding a small amount of emulsified oil emulsion made to increase lubricity and reduce corrosion. Late appeared to mineral oil as the working medium of the hydraulic machine of the 19th century. Oil has good lubricity, corrosion resistance and moderate viscosity, help to improve the performance of hydraulic machines. The second half of the 20th century there has been a new type of water-based emulsion, which emulsion form is "water in oil" instead of the original "oil in water." "Water in oil" emulsion external phase is oil, its lubricity and corrosion resistance close to the oil, and a small amount of oil, non-flammable. But the water-based emulsion expensive, limiting its promotion.

Pipe fittings commonly used in general

hydraulic fittings and hose connector tool pipeline between the connection point between elements can be removable and pipes. Serves as an indispensable role in the tube, it is the two hydraulic pipes constitute one of the main parts. Has a variety of types of pipe fittings, pipe fittings commonly used in general can be divided into two kinds of hardware fittings and hose fittings. If, pursuant to pipe fittings and pipe connections to points, hardware fittings have flared, ferrule and welded three, hose fittings are mainly withhold type hose fittings.

hydraulic connector standard

Card sets of pipe joints of the most important aspects of the pre-installed,
directly affects the reliability of sealing. Generally require a dedicated pre-
heater. The small diameter of t he connector in a vise on the pre-installed. In hydraulic adapter fittings practice, a connector as a parent, the nut and ferrule compression tube can. Card sets straight fittings, ferrule end straight-through connected to the head, the type of ferrule tube fittings. I found that even if the same factory shipment, the depth of the tapered hole in the connector body on these types are often not the same hydraulic hose clamps result is caused by a leak, but this is often overlooked. The correct approach is that the tube at one end with what kind of connector body connection, the connection end of the corresponding pre-installed with the same type of connector, so to avoid leakage problems.


 

construction machinery closed hydraulic system installation and commissioning

A large number of construction machinery, especially imported equipment, hydraulic drive and hydraulic drive is very common, such as tunnel boring machines, large tonnage transported beam cars, cranes, lifts truck, paver, excavators, b ulldozers and other . Hydraulic closed loop low energy consumption, compact and easy to achieve continuously variable transmission, has been widely used in the hydraulic system, but compared with the open loop, closed loop installation and debugging difficult to have a high and technical requirements, the following closed loop installation and commissioning of the main points to do a brief summary.
Before You Install hydraulic fittings
1.1 to maintain the cleanliness of the system components: carefully check the pumps and motors as well as all system components: fuel tank, piping, valves, fittings, radiators, etc., to ensure that no damage, pollution-free, valve block processing parts of the chip to clean up and cleaning.
1.2 hydraulic oil clean: Note the degree of contamination and humidity of the oil, to avoid any dirt into the tank. Fuel must go through the filter inside the tank is coated with the c oating must be compatible with the use of oil.
2 implementation of the installation process:hydraulic adaptors
2.1 to prohibit the use of force acting on the hydraulic system to avoid piping systems and components to withstand lateral forces and internal stress, we must pay attention to protect the piping system.
2.2 prohibit the use of twine, adhesive used as sealing materials, otherwise they will contaminate the system, and may result in system failure.
2.3 the right hose layout to avoid torsion of the hose, hold back the strength, abrasion and bump.
2.4 system, the connection must meet the recommended standard, all system piping to be joined and sealed to be reliable, no leakage phenomenon.
3 put into operation, commissioning hydraulic adapter fittings
If the hydraulic system requires the installation has been completed, you can begin to put into operation, the hydraulic system debugging. Before commissioning the hydraulic tank to join as much as possible and clean the hydraulic oil to fuel injection pump, motor shell, the primary system piping, mainly due to the viscosity of the oil, pipelines, pump suction line did not break out the air, plus debugging offline installers within 30 seconds the speed of the diesel engine from the startup surge speed to maximum speed, and fill the pump early wear and tear is inevitable.

Resistance to foaming of the hydraulic oil is better

1) shall not contain steam, air and other easy to gasification and gas impurities,or from the bubble, so that the work to occur flutter npt pipe fittings move, affecting the smooth working. Mass fraction o f water Germany shall not exceed 0.025%, the formation of water vapor, water will deteriorate the performance of the use of oil and impact of low-temperature work. Resistance to foaming of the hydraulic oil is better, the defoaming stronger. tube fitting Mineral oil usually can be dissolved in the atmosphere of 5% to 10% air, which is the main bubble to reason. Hydraulic pump oil absorption tube seal is not good to improper teflon hose hydraulic fittings installation or management, will produce the foam, it makes the hydraulic pump to generate noise and vibration dynamic characteristics of deterioration and therefore requires the hydraulic oil can be quickly and fully to defoaming, otherwise it will create the power loss increases, the temperature rise, The action is not stable.
2) erosion of parts and damage seals, that does not contain water-soluble acid and alkali ingredients.
3) in the working temperature and pressure, with excellent lubrication, shear stability and film strength.
4) chemical stability. Should not be in the process of storage and work production of oxide colloid, long-term use is not degenerate. When the system temperature degrees, pressure and flow rate changes, still maintain its original character, in the course of deterioration, no precipitation of asphalt, tar and other glial precipitation.
5) to minimize the impurities in the oil, does not allow precipitation to avoid wear and tear parts, clogging pipes and hydraulic components, affecting the system job.

Forging flange hydroforming principle of hydraulic machines

Forging flange hydroforming principle of hydraulic machines, such as powder molding products, plastic molding, cold (hot) extrusion metal forming, sheet steel, as well as the horizontal pressure welding elbow, turned through the correction process sewage pump hydraulic forming parts are usually only need one set of molds, and stampings are mostly multi-sets of molds. The meter can reduce the amount of subsequent machining and assembly welding. Chiller cooling area increased by 43% to radiator support, for example, the solder joint is reduced from 174 to 20, the process is reduced from 13 to 6 66% increase in productivity. Angle seat valve, reducing the number of parts and molds, improve the rigidity and strength, reduce production costs has obvious technical and economic advantages, especially in the automotive industry has been more and more applications in the industrial field. Compared with the conventional stamping process, hydroforming technology in reducing the weight of the radiator support part to reduce from 17 to 10. Its fundamental principle is based on the pipe to impose ultra-high pressure liquid inside the pipe as a blank, at th e same time, both ends of the tube by axial thrust is applied, feeding.
Reduce production costs. According to the part of statistical analysis has been applied hydraulic forming, hydroforming production costs 15% to 20% lower than average stampings, lower mold costs.9000psi flange together of the two external forces, the tube material plastic deformation and fit, and ultimately with the mold cavity wall, the shape and accuracy to meet the technical requirements of the hollow parts.

Of hydraulic, pneumatic and sealing industry development process

Our american hydraulic adapter(including hydraulic, the same below), pneumatic and seal industrial development process can be divided into three stages: the early 1950s to early 1960s infancy; 60 to 70 years of specialized production System growth stage; 80 to 90 years of rapid development stage. Among them, the hydraulic industry in the early 1950s imitated Soviet grinders, broaching, start copying lathes and other flat seal metric hydraulic fittings transmission, hydraulic components plant by the machine hydraulic workshop production, production for own use from the machine tool industry production. Into the 1960s, the application of hydraulic technology from the machine gradually extended to agricultural machinery and construction machinery and other fields, originally attached to the OEM hydraulic workshop some independence, and become a professional manufacturer of hydraulic parts. By the late 60s, early 70s, with the development of production mechanization, particularly in the second car factory to provide efficient, driven automation equipment, british hydraulic adapter components manufacturing has experienced rapid development of the situation, a group of SMEs It has become a professional manufacturer of hydraulic parts. 1968 Chinese hydraulic components production has nearly 200,000; 1973 in machine tools, agricultural machinery, engineering machinery and other industries, professional production of hydraulic parts factory has grown to more than 100, the annual output more than 1 million, a separate hydraulic parts Manufacturing has taken shape. In this case, hydraulic product development from the imitation of the Soviet Union for the introduction of technology and products to design a combination of product, pressure, and high pressure development, and the development of electro-hydraulic servo valves and systems, further expanding hydraulic applications. Hydraulic pneumatic industry started later than a few years, until 1967 to start building a professional factory pneumatic components, pneumatic components just as commodity production and sales. Containing rubber seals, mechanical seals and seal flexible graphite sealing industry, in the early 1950s from the production of ordinary O-rings, seals and other extruded rubber seals and asbestos sealing products start to the early 1960s, began to develop and produce mechanical seals and flexible graphite sealing products. 70s in the burning of the original part, a machine unit, the Ministry of Agricultural Machinery Systems, a group specializing in the production plants have been established and officially formed industry, laid the foundation for the development of the growth of the seal industry.

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, 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. May be more than one teflon hose.
   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.
