This article mainly introduces:

Pakistan hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder

(Pakistan spring return cylinder,produced by Hengyu Hydraulic Cylinder Factory）

spring return cylinder are widely used in Pakistan，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed spring return cylinder for customers from Pakistan.

Introduction to spring return cylinder:

The spring return cylinder should be vented: when the spring return cylinder is installed or parked for a long time to work again, the air will penetrate into the spring return cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the spring return cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the spring return cylinder, the oil is best entered and discharged from the highest point of the spring return cylinder. spring return cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

spring return cylinder buffer valve inspection and maintenance: For the valve buffer spring return cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

The material of the sliding part of the spring return 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 advantages and disadvantages of the spring return cylinder: the surface of the spring return cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the spring return cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

Answers to some questions about spring return cylinder:

What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.
