(Finland lifting hydraulic cylinder,produced by Hebei Hengyu company）

lifting hydraulic cylinder are widely used in Finland，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed lifting hydraulic cylinder for customers from Finland.

Introduction to lifting hydraulic cylinder:

The material of the sliding part of the lifting hydraulic 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.

The difference between the integral lifting hydraulic cylinder and the split lifting hydraulic cylinder: The integral lifting hydraulic cylinder and the split lifting hydraulic cylinder in the lifting hydraulic cylinder are two different lifting hydraulic cylinders, and they are very different. The whole lifting hydraulic cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split lifting hydraulic cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and lifting hydraulic cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Because of the slightly complex structure of the buffer lifting hydraulic cylinder, sometimes there will be problems, such as when the lifting hydraulic cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

The scar on the sliding surface of the lifting hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the lifting hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

Answers to some questions about lifting hydraulic cylinder:

How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
