(Switzerland pile driver hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to pile driver hydraulic cylinder:

The repair method of the pile driver hydraulic cylinder: the repair of the pile driver hydraulic cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

When the control pressure of the hydraulic system is too low, the pile driver hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

How to repair the pile driver hydraulic cylinder body when it is damaged: When the pile driver hydraulic cylinder has trace deformation and shallow tensile marks, the pile driver hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair pile driver hydraulic cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the pile driver hydraulic cylinder can meet the technical requirements.

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.

Answers to some questions about pile driver hydraulic cylinder:

What type of seal is the cylinder of shaft 50?
You won't know the exact model until you take it apart. Oil seals have O, Y, Yx, KYx, U, UN, UHS, YA, St, Gray, Yamagata, Lei type, etc. It is difficult to know what kind of oil seal the designer chooses. Cylinder oil seal installation method: 1. Receive a fixed number of oil seals. 2. From receiving the oil seal to assembly, it must be kept clean. 3. Before assembly, check the oil seal and measure whether the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The inner cavity size should be suitable for the outer diameter width of the oil seal. Check the lip of the oil seal for damage.

Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.
