self-locking hydraulic cylinder are widely used in Saudi Arabia，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed self-locking hydraulic cylinder for customers from Saudi Arabia.

Introduction to self-locking hydraulic cylinder:

The self-locking hydraulic cylinder should be vented: when the self-locking hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the self-locking hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the self-locking hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the self-locking hydraulic cylinder, the oil is best entered and discharged from the highest point of the self-locking hydraulic cylinder. self-locking hydraulic 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.

When installing the self-locking hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the self-locking hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the self-locking hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the self-locking hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the self-locking hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

When the self-locking hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the self-locking hydraulic 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 the self-locking hydraulic cylinder is customized, if there are high requirements for the quality of the self-locking hydraulic cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the self-locking hydraulic cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the self-locking hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Answers to some questions about self-locking hydraulic cylinder:

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.
