(Sudan reciprocating cylinder,produced by Hengyu Group）

reciprocating cylinder are widely used in Sudan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed reciprocating cylinder for customers from Sudan.

Introduction to reciprocating cylinder:

If the reciprocating cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

reciprocating cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the reciprocating cylinder is placed for a period of time, the reciprocating cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

The material, shape and compression of the reciprocating cylinder seal have a great impact on the service life and work efficiency of the reciprocating cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

When the reciprocating cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the reciprocating cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the reciprocating cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about reciprocating cylinder:

Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.

How to calculate hydraulic cylinder flow?
Effective area of the cylinder x stroke = volume usually in liters. Volume/estimated total travel time (converted to minutes) = oil flow rate.
