France construction machinery hydraulic cylinder

(France construction machinery hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

construction machinery hydraulic cylinder are widely used in France,because of no need for deceleration device,long service life,smooth movement.So our company has designed construction machinery hydraulic cylinder for customers from France.

Introduction to construction machinery hydraulic cylinder:

In the case of serious wear on the inner surface of the construction machinery hydraulic cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the construction machinery hydraulic cylinder manufacturing process for replacement. The construction machinery hydraulic cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

The construction machinery 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 construction machinery hydraulic cylinder can use 20 steel pipe, and the high pressure construction machinery hydraulic cylinder can use 45 steel pipe.

The construction machinery hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the construction machinery hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The construction machinery hydraulic cylinder is basically composed of construction machinery hydraulic cylinder and construction machinery hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

When the construction machinery hydraulic 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 construction machinery hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the construction machinery hydraulic 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 construction machinery hydraulic 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.

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.
