trailer hydraulic cylinder are widely used in Peru，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed trailer hydraulic cylinder for customers from Peru.

Introduction to trailer hydraulic cylinder:

The material of the sliding part of the trailer hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

The internal leakage of the trailer hydraulic cylinder should be prevented when the trailer hydraulic cylinder is used. The internal leakage of trailer hydraulic cylinder includes the leakage caused by excessive wear of trailer hydraulic cylinder block seal, piston rod and seal cover seal and 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.

Repair method of small range wear of oil trailer hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

The trailer hydraulic cylinder should be used correctly and maintained regularly. The trailer hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the trailer hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

Answers to some questions about trailer hydraulic cylinder:

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.

How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
