Switzerland hydraulic cylinder,electric lift cylinder manufacturer,electric lift cylinder

(Switzerland electric lift cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to electric lift cylinder:

Before the electric lift cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

When purchasing the electric lift cylinder, try to clarify the following parameters of the electric lift cylinder: A. electric lift cylinder diameter, rod diameter, stroke; B. Working pressure or electric lift cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right electric lift cylinder type can be found accurately and quickly.

When the electric lift cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the electric lift cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

electric lift cylinder hydraulic oil selection: The recommended working oil viscosity of the electric lift cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

Answers to some questions about electric lift cylinder:

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.

How to select the propulsion cylinder according to the shield attitude, cylinder stroke, shield tail clearance and other factors?
Generally, the shield machine will be equipped with the corresponding cylinder. Soil pressure balancing machine, mud water balancing machine have the corresponding cylinder, there will be no insufficient cylinder force. In the jacking process of the pipe jacking machine, there are certain requirements for the jacking force of the cylinder.
