Kazakhstan unidirectional cylinder

(Kazakhstan unidirectional cylinder,produced by Hengyu Hydraulic Co., Ltd)

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

Introduction to unidirectional cylinder:

How the cavitation of the unidirectional cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the unidirectional cylinder, resulting in corrosive damage to the parts.

The method of sleeve unidirectional 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 unidirectional cylinder can be significantly improved by rolling in the finishing of the inner holes of the unidirectional cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

When the unidirectional cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the unidirectional cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

The piston rod of the unidirectional cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Answers to some questions about unidirectional cylinder:

The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.
