(Qatar stern plate hydraulic cylinder,produced by Hengyu Group）

stern plate hydraulic cylinder are widely used in Qatar，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed stern plate hydraulic cylinder for customers from Qatar.

Introduction to stern plate hydraulic cylinder:

Protection of the stern plate hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the stern plate hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the stern plate hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the stern plate hydraulic cylinder should be cleaned up in time.

stern plate hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards stern plate hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the stern plate hydraulic cylinder guide is determined by the length of the stroke. Check the strength of stern plate hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

When the piston speed of the stern plate hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the stern plate hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

The material, shape and compression of the stern plate hydraulic cylinder seal have a great impact on the service life and work efficiency of the stern plate hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

Answers to some questions about stern plate hydraulic cylinder:

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.

How to select the propulsion cylinder according to the shield attitude, cylinder stroke, shield tail clearance and other factors?
Generally, the shield machine will be equipped with the corresponding cylinder. Soil pressure balancing machine, mud water balancing machine have the corresponding cylinder, there will be no insufficient cylinder force. In the jacking process of the pipe jacking machine, there are certain requirements for the jacking force of the cylinder.
