(Ethiopia unidirectional cylinder,produced by Hengyu Hydraulic Cylinder Factory）

unidirectional cylinder are widely used in Ethiopia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed unidirectional cylinder for customers from Ethiopia.

Introduction to unidirectional cylinder:

unidirectional cylinder buffer valve inspection and maintenance: For the valve buffer unidirectional cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

unidirectional cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards unidirectional cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the unidirectional cylinder guide is determined by the length of the stroke. Check the strength of unidirectional cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

unidirectional cylinder hydraulic oil selection: The recommended working oil viscosity of the unidirectional cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

The daily inspection of the unidirectional cylinder includes: checking the connection of the unidirectional cylinder and the pipe joint for leaks. Check the unidirectional cylinder rod for leaks. Check the unidirectional cylinder connection for leaks. When the unidirectional cylinder moves, the work is normal and smooth. Whether the unidirectional cylinder has internal leakage.

Answers to some questions about unidirectional cylinder:

Does the excavator use a hydraulic cylinder?
First, construction machinery is generally a hydraulic cylinder. Second, hydraulic transmission equipment is usually composed of four components, power, execution, control and auxiliary. And the hydraulic cylinder as a linear reciprocating motion or less than 360. Reciprocating motion of the hydraulic mechanism, simple structure, reliable work, is also widely used in the hydraulic system of the main actuator, it is the prime mover in the form of mechanical energy to drive the hydraulic pump produced by the liquid pressure energy, and then can be directly driven load for reciprocating movement or less than 360.

How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.
