(Cote d 'Ivoire pushing cylinder,produced by Hengyu Hydraulic Co., Ltd）

pushing cylinder are widely used in Cote d 'Ivoire，because of no need for deceleration device，long service life，smooth movement.So our company has designed pushing cylinder for customers from Cote d 'Ivoire.

Introduction to pushing cylinder:

When the pushing cylinder is in use, ensure that the pushing cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

pushing cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the pushing cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the pushing cylinder. c. The pushing cylinder seal is extruded, if the O-ring is obviously extruded at the pushing cylinder seal, replace the pushing cylinder seal.

If the pushing 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 pushing cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow pushing cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the pushing cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the pushing cylinder includes the leakage caused by excessive wear of the pushing 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 pushing cylinder, and the phenomenon of "pulling the pushing cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

How to repair the pushing cylinder body when it is damaged: When the pushing cylinder has trace deformation and shallow tensile marks, the pushing cylinder is repaired by strong honing process. The heavy honing process can repair pushing cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the pushing cylinder can meet the technical requirements.

Answers to some questions about pushing cylinder:

How to remove the lifting cylinder from the forklift truck?
The lifting cylinder is generally fixed on the door frame, and there are screws under and above it, and it is OK to loosen the screws with a wrench on the top. However, we must pay attention to ensure safety and prevent damage to the cylinder or safety accidents.

Why does the hydraulic cylinder go up to the top and then slowly go down?
Leakage in the cylinder or the hydraulic valve that controls the cylinder, can be replaced and removed. Or add a pressure retaining valve to the hydraulic system to ensure pressure.
