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.

the seal damage affect the machining industry on the maintenance of hydraulic equipment

the seal damage affect the machining industry on the maintenance of hydraulic machines, hydraulic transmission is widely used, such as various types of semi-automatic hydraulic transmission lathe. During use, these machines often appear, such as impact, reptiles and other fault diagnosis and mai ntenance, often in the hydraulic control elements (such as various types of pumps, monoblock hydraulic valves) can not find the cause of the malfunction, resulting in maintenance work in trouble. The final of such failure or often on the implementation of the components to find the reasons, that the cylinder piston sealing elements of serious wear and tear caused by. Class phenomenon especially in the \"O\" ring to see more.

hydraulic plate bending machine structural characteristics

Hydraulic plate bending machine structure and characteristics:
(1) hydraulic drive, the machine at both ends of the fuel tank is placed in the slider, the direct drive slide work.
(2) using the machinery of block structure, stable and reliable.
(3) slide stroke motor fast tune, manual fine-tuning, the counter display.
(4) Solid steel welded construction of sufficient strength and rigidity.
(5) slider synchronization mechanism with torsion bar forced synchronization.
(6) Wedge deflection compensation agencies, in order to guarantee access to high bending accuracy.
Hydraulic plate bending machine, hydraulic hose clamps cylinder, end caps, cylinder, the outer piston rod flange set, piston rod, screw, nut and gland; end caps fixed in the cylinder at one end and screw sets , the other end of the fixed nut and gland in the cylinder, the outer piston rod located in the cylinder body, the flange is to be placed on the outer piston rod piston side of the piston within the piston rod end inserted into the outer piston rod within the piston fixed installation of the rod end of the rod end cap, within the piston rod within the opening oil duct. Hydraulic fittings cylinder more than the traditional kind hydraulic cylinder a rod chamber and the rod chamber, and thus has a unique quick drive function in the hydraulic system of the same driving conditions, fuel tanks owned or weightless out knife conditions still can be easily two growth; screw sets of contact with the force area is much larger than the traditional bending machine, hydraulic cylinder adjustment nut, thereby increasing the contact stiffness and stability, to ensure better accuracy of the limit.

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. Hydroforming stamping parts to reduce from 20% to 40%; the hollow stepped shaft parts can be reduced from 40% to 50% of the weight. Improve the strength and stiffness, fatigue strength, such as hydroforming of radiator support, the stiffness in the vertical direction can be increased by 39%, the horizontal direction can be increased by 50%.
Polyurethane stamping and welding process compared to the hydroforming technology and process the following key benefits: hydroforming, also known as hydroforming, hydroforming typical part of the car engine bay, radiator support, engine bay parts reduced from six to one to reduce the quality of material savings. Reduce the number of parts and molds, and reduce tooling costs. Valve test bench hydraulic forming (hydroforming) for the realization of structural lightweight advanced manufacturing technology.

the hydraulic piping systems technical information - fittings and flanges

In the high quality requirements of hydraulic lines or other piping systems, we recommend the use of non-welded connection technology (fittings and flanges, etc.), because of the high reliability of non-welded connection system and its i nherent high in all piping Cleanliness. This connection technology used depends on the system working pressure and pipe size. Material depends on the specific conditions (or the customer s specific hydraulic flange requirements).
For greater than or equal to 25mm piping, we recommend using the GS-37 ° Flare Flange and GS-Retain Ring System. Less than 25mm piping, we recommend using the connector, tube end forming the connector ferrule connector, or 37 ° JIC expansion port, depending on the specific conditions and design requirements.metric hydraulic hose fittings

Hydraulic hose during use should pay attention to the following points

Hydraulic hose during use should pay attention to the following points:
1, Long-term use of the hose clamps should be checked regularly. (The degree of aging and skin abrasion, wear the joint proposal checked once a week).
2, High pressure hose surface cleaning. (Production materials daily cleaning hose surface to keep clean, clear focus on the hose surface corrosive material)
3, When the hose regularly and friction surface contact, use protective liner. Reduce the friction coefficient, increase the service life and prevent aging.
4, Has been used hoses, take a long time when not material to tube cleaned, and then pass into the media kept closed.
5. Do not hose when the hose storage place outdoors. Or because of other factors caused by pollution and sunshine hose aging.
