Oman hydraulic cylinder,500 tons hydraulic press cylinder manufacturer,500 tons hydraulic press cylinder(Oman 500 tons hydraulic press cylinder,produced by Hengyu Hydraulic Co., Ltd)
500 tons hydraulic press cylinder are widely used in Oman,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed 500 tons hydraulic press cylinder for customers from Oman.
When the 500 tons hydraulic press cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
Most of the failure of the 500 tons hydraulic press cylinder is because there is a foreign body in the 500 tons hydraulic press cylinder into the failure of the 500 tons hydraulic press cylinder, the most problematic is that it is difficult to determine when the foreign body is into the 500 tons hydraulic press cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular 500 tons hydraulic press cylinder action. Troubleshooting method: Replace the rubber hose.
When the piston speed of the 500 tons hydraulic press cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the 500 tons hydraulic press cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.
