Austria hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder(Austria series synchronous cylinder,produced by Hengyu Hydraulic Cylinder Factory)
series synchronous cylinder are widely used in Austria,because of no need for deceleration device,long service life,smooth movement.So our company has designed series synchronous cylinder for customers from Austria.
In the process of using the series synchronous cylinder, sometimes such a problem will occur, the series synchronous cylinder can not act immediately after the instruction of the series synchronous cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil series synchronous cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.
Causes and countermeasures of oil series synchronous cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the series synchronous cylinder will lead to premature wear of the piston seal, replace the piston seal; If the series synchronous cylinder is visibly scarred, the series synchronous cylinder must be replaced. It can be pressurized at one end of the series synchronous cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most series synchronous cylinder piston drift may not come from the series synchronous cylinder, the above method to determine the series synchronous cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
The material of the sliding part of the series synchronous cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
series synchronous cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the series synchronous cylinder is placed for a period of time, the series synchronous 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.
Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.
How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.
