Turkmenistan hydraulic cylinder,lift cylinder of forklift truck manufacturer,lift cylinder of forklift truck

(Turkmenistan lift cylinder of forklift truck,produced by Hengyu Hydraulic Co., Ltd）

lift cylinder of forklift truck are widely used in Turkmenistan，because of no need for deceleration device，long service life，smooth movement.So our company has designed lift cylinder of forklift truck for customers from Turkmenistan.

Introduction to lift cylinder of forklift truck:

When the lift cylinder of forklift truck is customized, if there are high requirements for the quality of the lift cylinder of forklift truck, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the lift cylinder of forklift truck can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the lift cylinder of forklift truck and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

lift cylinder of forklift truck body inspection: The inner surface of the lift cylinder of forklift truck and the piston seal are the main factors causing the leakage in the lift cylinder of forklift truck, if the lift cylinder of forklift truck has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the lift cylinder of forklift truck mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Regular maintenance of the lift cylinder of forklift truck includes: regular tightening, lift cylinder of forklift truck fastening screws and gland screws, lift cylinder of forklift truck piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the lift cylinder of forklift truck once a year. Clean regularly, the lift cylinder of forklift truck is cleaned every other year, and the seals are replaced while cleaning.

The machining accuracy of the lift cylinder of forklift truck depends on the level of equipment, production technology and testing means. lift cylinder of forklift truck processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Answers to some questions about lift cylinder of forklift truck:

Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.
