(Estonia pile driver hydraulic cylinder,produced by Hebei Hengyu company）

pile driver hydraulic cylinder are widely used in Estonia，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed pile driver hydraulic cylinder for customers from Estonia.

Introduction to pile driver hydraulic cylinder:

Causes and countermeasures of oil pile driver hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the pile driver hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the pile driver hydraulic cylinder is visibly scarred, the pile driver hydraulic cylinder must be replaced. It can be pressurized at one end of the pile driver hydraulic 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 pile driver hydraulic cylinder piston drift may not come from the pile driver hydraulic cylinder, the above method to determine the pile driver hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

If the piston rod and pile driver hydraulic cylinder are stuck or the pile driver hydraulic cylinder is blocked, at this time, no matter how to operate, the pile driver hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the pile driver hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When the pile driver hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the pile driver hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

If the seal of the pile driver hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material 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 pile driver hydraulic cylinder, and the phenomenon of "pulling the pile driver hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Answers to some questions about pile driver hydraulic cylinder:

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.

Why does the hydraulic cylinder rebound after the rod cavity is extended into place?
The reason is that after the rod cavity is extended into place, the rod cavity and the rodless cavity are connected, so that the cylinder moves towards the rod cavity. After connecting, it is equivalent to the hydraulic oil directly driving the cylinder with an area equal to the piston rod. After the end of this problem, it is estimated that the seal is not very good, and the two cavities are connected after the pressure is increased to a certain extent; Or there is a problem in the valve, so that the two chambers are connected after reaching a certain pressure. Other phenomena: If the load is increased to a certain extent, no matter which side of the solenoid valve is energized, the cylinder will move to the rod cavity.
