(Tanzania stern plate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

stern plate hydraulic cylinder are widely used in Tanzania，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stern plate hydraulic cylinder for customers from Tanzania.

Introduction to stern plate hydraulic cylinder:

Before the stern plate hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

When the stern plate hydraulic cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the stern plate hydraulic cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

Regular maintenance of the stern plate hydraulic cylinder includes: regular tightening, stern plate hydraulic cylinder fastening screws and gland screws, stern plate hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the stern plate hydraulic cylinder once a year. Clean regularly, the stern plate hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.

When the stern plate hydraulic cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Answers to some questions about stern plate hydraulic cylinder:

What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.

What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.
