servo hydraulic cylinder are widely used in Uganda，because of long service life，smooth movement，high work efficiency.So our company has designed servo hydraulic cylinder for customers from Uganda.

Introduction to servo hydraulic cylinder:

How to repair the servo hydraulic cylinder body when it is damaged: When the servo hydraulic cylinder has trace deformation and shallow tensile marks, the servo hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair servo 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 servo hydraulic cylinder can meet the technical requirements.

When the servo hydraulic cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the servo hydraulic cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the servo hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Factors that should be considered when selecting the oil seal in the servo hydraulic cylinder: some specific factors should be taken into account when selecting the oil seal in the servo hydraulic cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: servo hydraulic cylinder diameter, piston rod diameter, piston rod and piston groove size, servo hydraulic cylinder working pressure, servo hydraulic cylinder movement speed, hydraulic system oil temperature and servo hydraulic cylinder working environment.

Answers to some questions about servo hydraulic cylinder:

How to disassemble the cylinder?
Generally speaking, it is not difficult to disassemble the hydraulic cylinder, as long as you are careful, but you often encounter some small trouble in the disassembly process, because the disassembly process is not correct. In fact, this can be avoided, as long as you follow below points. 1. Before removing the hydraulic cylinder, the hydraulic circuit should be relieved of pressure, otherwise, when the oil pipe connected with the cylinder is loosened, the high-pressure oil in the circuit will be rapidly ejected. When the hydraulic pressure comes back, the handwheel or pressure regulating screw at the relief valve should be loosened first, so that the pressure oil is unloaded, and then the power supply or power source is cut off, so that the hydraulic device stops running. 2. Disassembly should prevent damage to the top thread of the piston rod, the oil thread and the chrome layer on the piston rod surface.

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.
