(Ethiopia stainless steel cylinder,produced by Hengyu Hydraulic Co., Ltd）

stainless steel cylinder are widely used in Ethiopia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stainless steel cylinder for customers from Ethiopia.

Introduction to stainless steel cylinder:

Under normal circumstances, the stainless steel cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the stainless steel cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the stainless steel cylinder and the end cover, the piston and the piston rod, the piston and the stainless steel cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the stainless steel cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

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

When the stainless steel cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the stainless steel cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil stainless steel cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical stainless steel cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the stainless steel cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

stainless steel cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the stainless steel cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

Answers to some questions about stainless steel cylinder:

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.

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.
