(S.Africa jacking hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

jacking hydraulic cylinder are widely used in S.Africa，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed jacking hydraulic cylinder for customers from S.Africa.

Introduction to jacking hydraulic cylinder:

How to repair the jacking hydraulic cylinder body when it is damaged: When the jacking hydraulic cylinder has trace deformation and shallow tensile marks, the jacking hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair jacking hydraulic cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the jacking hydraulic cylinder can meet the technical requirements.

The jacking hydraulic cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

Protection of the jacking hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the jacking hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the jacking 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 jacking hydraulic cylinder should be cleaned up in time.

When the jacking hydraulic cylinder is installed, the piston and the jacking hydraulic 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 jacking hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the jacking hydraulic 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 jacking hydraulic cylinders, only careful and careful operation can be avoided.

Answers to some questions about jacking hydraulic cylinder:

What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.

Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
