(Belarus push bench hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to push bench hydraulic cylinder:

The internal leakage of the push bench hydraulic cylinder is an important indicator to measure the quality of the push bench hydraulic cylinder: the internal leakage of the push bench hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the push bench hydraulic cylinder, so that the push bench hydraulic cylinder can not accurately and stably stop in a certain position of the push bench hydraulic cylinder, so it is one of the main indicators of the push bench hydraulic cylinder.

The push bench hydraulic cylinder should be vented: when the push bench hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the push bench hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the push bench hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the push bench hydraulic cylinder, the oil is best entered and discharged from the highest point of the push bench hydraulic cylinder. push bench hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

The push bench hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure push bench hydraulic cylinder can use 20 steel pipe, and the high pressure push bench hydraulic cylinder can use 45 steel pipe.

The push bench hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the push bench hydraulic cylinder should pay attention to: the operation should be as far away from the push bench hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the push bench hydraulic cylinder coating. When cleaning the push bench hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the push bench hydraulic cylinder when the oil temperature exceeds 70 ° C.

Answers to some questions about push bench hydraulic 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.

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
