Korea hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder(Korea stroke adjustable cylinder,produced by Hengyu Group)
stroke adjustable cylinder are widely used in Korea,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed stroke adjustable cylinder for customers from Korea.
stroke adjustable cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.
Before the stroke adjustable 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.
stroke adjustable cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the stroke adjustable cylinder is placed for a period of time, the stroke adjustable cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.
The internal leakage of the stroke adjustable cylinder is an important indicator to measure the quality of the stroke adjustable cylinder: the internal leakage of the stroke adjustable cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the stroke adjustable cylinder, so that the stroke adjustable cylinder can not accurately and stably stop in a certain position of the stroke adjustable cylinder, so it is one of the main indicators of the stroke adjustable cylinder.
What hydraulic valve is used to control a cylinder back and forth?
Direction valve is available. Direction valve includes electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve, the specific choice of which direction valve, you need to see the use of conditions.
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.
