Ethiopia hydraulic cylinder,yg series hydraulic cylinder manufacturer,yg series hydraulic cylinder

(Ethiopia yg series hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to yg series hydraulic cylinder:

yg series hydraulic cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the yg series hydraulic 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.

yg series hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the yg series hydraulic cylinder is placed for a period of time, the yg series hydraulic 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.

yg series hydraulic 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.

After the yg series hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

Answers to some questions about yg series hydraulic cylinder:

CNC lathe rotary cylinder oil leakage and treatment methods
Oil leakage often occurs when the cylinder (especially the hollow cylinder) of the CNC lathe is installed. First check the cylinder yaw, be sure to reach or close to the required value, generally the cylinder requires the outer beat within 1 wire. Otherwise, too much beating is sure to leak oil. Then check whether the tubing is smoothly downward at a certain Angle, and can not bend. Look at the pipe outlet can not go into the oil level, to a little higher. Otherwise, there's back pressure and it's gonna leak.

What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.
