Congo self-locking hydraulic cylinder

(Congo self-locking hydraulic cylinder,produced by Hebei Hengyu company)

self-locking hydraulic cylinder are widely used in Congo,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed self-locking hydraulic cylinder for customers from Congo.

Introduction to self-locking hydraulic cylinder:

The method of sleeve self-locking hydraulic cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the self-locking hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the self-locking hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

When the initial action of the self-locking hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the self-locking hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

The machining accuracy of the self-locking hydraulic cylinder depends on the level of equipment, production technology and testing means. self-locking hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

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

Answers to some questions about self-locking hydraulic cylinder:

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.

Slide weight 35 kg exit stroke 55mm, is it suitable to use 40 cylinder diameter cylinder?
The maximum output force of the 40-bore hydraulic cylinder can reach 2 tons, and whether it can be used depends on the use scenario. In addition, the problem of mechanism stuck has nothing to do with the size of the power source, and reasonable structural design and good machining and assembly accuracy are the key.
