Korea hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Korea synchronous hydraulic cylinder,produced by Hengyu Group)
synchronous hydraulic cylinder are widely used in Korea,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed synchronous hydraulic cylinder for customers from Korea.
synchronous hydraulic cylinder buffer valve inspection and maintenance: For the valve buffer synchronous hydraulic cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
If the synchronous hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the synchronous hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow synchronous hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the synchronous hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the synchronous hydraulic cylinder includes the leakage caused by excessive wear of the synchronous hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and synchronous hydraulic cylinder, and the phenomenon of "pulling the synchronous hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.
There are some honeycomb holes in the inner wall of the synchronous hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the synchronous hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the synchronous hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the synchronous hydraulic cylinder is targeted to prevent. Is very necessary.
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 synchronous hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.
What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.
How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.
