Ghana pushing cylinder

(Ghana pushing cylinder,produced by Hengyu Group)

pushing cylinder are widely used in Ghana,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed pushing cylinder for customers from Ghana.

Introduction to pushing cylinder:

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

Analysis of commonly used seals: The wear ring and slip ring commonly used on the pushing cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

Do not regularly check the damage of the chrome layer of the pushing cylinder: completely extend the pushing cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the pushing cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the pushing cylinder seal. Welding slag is strictly prohibited on the surface of the pushing cylinder.

When the piston speed of the pushing cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the pushing cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Answers to some questions about pushing cylinder:

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
