Congo hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder

(Congo supporting cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to supporting cylinder:

The daily inspection of the supporting cylinder includes: checking the connection of the supporting cylinder and the pipe joint for leaks. Check the supporting cylinder rod for leaks. Check the supporting cylinder connection for leaks. When the supporting cylinder moves, the work is normal and smooth. Whether the supporting cylinder has internal leakage.

The "O" ring can be used as an auxiliary seal inside the supporting cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the supporting cylinder, and can be completely sealed.

Before the supporting cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

When purchasing the supporting cylinder, try to clarify the following parameters of the supporting cylinder: A. supporting cylinder diameter, rod diameter, stroke; B. Working pressure or supporting cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right supporting cylinder type can be found accurately and quickly.

Answers to some questions about supporting cylinder:

What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
