Chile pressure retaining cylinder

(Chile pressure retaining cylinder,produced by Hengyu Hydraulic Co., Ltd)

pressure retaining cylinder are widely used in Chile,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed pressure retaining cylinder for customers from Chile.

Introduction to pressure retaining cylinder:

Classification of pressure retaining cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

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

pressure retaining cylinder and hydraulic station selection: Select the type and structure of the pressure retaining cylinder according to the operation requirements of the main engine. According to the external load force borne by the pressure retaining cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the pressure retaining cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the pressure retaining cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the pressure retaining cylinder, the diameter of the piston and the piston rod.

In the process of using the pressure retaining cylinder, sometimes such a problem will occur, the pressure retaining cylinder can not act immediately after the instruction of the pressure retaining cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil pressure retaining cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Answers to some questions about pressure retaining cylinder:

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
