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

unidirectional cylinder are widely used in Malaysia，because of excellent temperature resistance，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed unidirectional cylinder for customers from Malaysia.

Introduction to unidirectional cylinder:

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.

The internal leakage of the unidirectional cylinder should be prevented when the unidirectional cylinder is used. The internal leakage of unidirectional cylinder includes the leakage caused by excessive wear of unidirectional cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

unidirectional cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

When the unidirectional cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the unidirectional cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the unidirectional cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the unidirectional cylinder can meet the requirements by grinding. However, the life and reliability of this repair unidirectional cylinder are not high.

Answers to some questions about unidirectional cylinder:

When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
