Mexico trailer hydraulic cylinder

(Mexico trailer hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

trailer hydraulic cylinder are widely used in Mexico,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed trailer hydraulic cylinder for customers from Mexico.

Introduction to trailer hydraulic cylinder:

The internal leakage of the trailer hydraulic cylinder is an important indicator to measure the quality of the trailer hydraulic cylinder: the internal leakage of the trailer hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the trailer hydraulic cylinder, so that the trailer hydraulic cylinder can not accurately and stably stop in a certain position of the trailer hydraulic cylinder, so it is one of the main indicators of the trailer hydraulic cylinder.

When the trailer hydraulic cylinder is customized, if there are high requirements for the quality of the trailer hydraulic cylinder, 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 trailer hydraulic cylinder 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 trailer hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

If the trailer hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the trailer hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow trailer hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the trailer hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the trailer hydraulic cylinder includes the leakage caused by excessive wear of the trailer hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and trailer hydraulic cylinder, and the phenomenon of "pulling the trailer hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The trailer hydraulic cylinder is not the same as the trailer hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the trailer hydraulic cylinder can not be used as a high-power power component, but the trailer hydraulic cylinder can be used as a relatively large power component, or the trailer hydraulic cylinder system can be used.

Answers to some questions about trailer hydraulic cylinder:

Loader arm fell badly, how to know which oil cylinder is leaking?
No matter which cylinder leakage the arm will drop, it is best to replace the oil seal, even if one cylinder is good, it will not last long, and it will drop the arm, so the two cylinders should be replaced at once.

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
