(Uruguay reset cylinder,produced by Hebei Hengyu company）

reset cylinder are widely used in Uruguay，because of clever hydraulic energy conversion，high work efficiency，excellent fatigue and impact resistance.So our company has designed reset cylinder for customers from Uruguay.

Introduction to reset cylinder:

How to repair the reset cylinder body when it is damaged: When the reset cylinder has trace deformation and shallow tensile marks, the reset cylinder is repaired by strong honing process. The heavy honing process can repair reset 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 reset cylinder can meet the technical requirements.

There are some honeycomb holes in the inner wall of the reset cylinder, piston or piston rod surface. How is this formed? When we repair the reset cylinder, we can see that there are some honeycomb holes on the inner wall of the reset cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the reset cylinder is targeted to prevent. Is very necessary.

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

If the seal of the reset cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material 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 reset cylinder, and the phenomenon of "pulling the reset cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Answers to some questions about reset cylinder:

What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
