(Latvia high pressure cylinder,produced by Hengyu Hydraulic Co., Ltd）

high pressure cylinder are widely used in Latvia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed high pressure cylinder for customers from Latvia.

Introduction to high pressure cylinder:

When the high pressure cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the high pressure cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The internal leakage of the high pressure cylinder should be prevented when the high pressure cylinder is used. The internal leakage of high pressure cylinder includes the leakage caused by excessive wear of high pressure 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.

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

When the high pressure cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the high pressure cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

Answers to some questions about high pressure cylinder:

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
