(Uganda pressure retaining cylinder,produced by Hengyu Group）

pressure retaining cylinder are widely used in Uganda，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed pressure retaining cylinder for customers from Uganda.

Introduction to pressure retaining cylinder:

When the pressure retaining cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the pressure retaining cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

After chrome plating of the piston rod of the pressure retaining cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

The pressure retaining cylinder should be vented: when the pressure retaining cylinder is installed or parked for a long time to work again, the air will penetrate into the pressure retaining cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the pressure retaining cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the pressure retaining cylinder, the oil is best entered and discharged from the highest point of the pressure retaining cylinder. pressure retaining 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 the pressure retaining cylinder is installed, the piston and the pressure retaining cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the pressure retaining cylinder head boss is easy to cause scars when it hits the inner surface of the pressure retaining cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized pressure retaining cylinders, only careful and careful operation can be avoided.

Answers to some questions about pressure retaining cylinder:

What is the problem that the cylinder stroke is not in place?
1. Mechanical cause: the piston rod bends; If there is a synchronous cylinder, the stroke of the two cylinders may be different. 2. Hydraulic reason: the system back pressure is too large; The actuator load increases while the system pressure decreases. The electric is not sent, the reversing valve is not reset or stuck, the oil is too dirty, there is gas in the system, the external inertia load is too large, and the cylinder stroke is not in place.

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.
