(Oman spring return cylinder,produced by Hebei Hengyu company）

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

Introduction to spring return cylinder:

When the spring return cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the spring return cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

When using the spring return cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the spring return cylinder block. If the spring return cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the spring return cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the spring return cylinder, so that the working efficiency of the spring return cylinder is reduced.

Before the spring return cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

The main role of the spring return cylinder: the spring return cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the spring return cylinder realizes reciprocating motion. The structure of the spring return cylinder has three categories: piston spring return cylinder, plunger spring return cylinder, swing spring return cylinder, piston spring return cylinder and plunger spring return cylinder to achieve reciprocating linear motion, output speed and thrust, swing spring return cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the spring return cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The spring return cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Answers to some questions about spring return cylinder:

Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.

What is the rated pressure of the general cylinder?
This depends on the model of the cylinder, 1. The rated pressure of the light tie rod cylinder is 7 series 7MPa and 14 series 14MPa. 2. Rated pressure of engineering cylinder 16MPa. 3. Rexroth type metallurgical cylinder rated pressure 250MPa.
