Slovenia hydraulic cylinder,rack cylinder manufacturer,rack cylinder
(Slovenia rack cylinder,produced by Hengyu Group）
rack cylinder are widely used in Slovenia，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed rack cylinder for customers from Slovenia.
rack cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the rack cylinder is placed for a period of time, the rack 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 rack cylinder should be used correctly and maintained regularly. The rack cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the rack cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
The rack 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 rack cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The rack cylinder is basically composed of rack cylinder and rack 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.
We can not just consider the price and ignore the quality when we purchase the rack cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the rack cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the rack cylinder is not required.
What should we pay attention to when using the cylinder?
When using the cylinder, we should pay attention to the environment and temperature in which it is located as follows: 1. Before working, the hydraulic cylinder must carry out several reciprocating movements under low pressure (greater than the starting pressure), and work normally after removing the gas in the cylinder. 2. Precautions when removing the hydraulic cylinder: ① The pressure in the hydraulic circuit is reduced to zero before disassembly. ② The screw thread at the top of the piston rod should be prevented from damage when disassembling. ③ Due to the different structure and size of the hydraulic cylinder, the order of disassembly is also slightly different. Generally, the fastening bolt of the end cover should be loosened first. Internal card chain card key application special tools.
Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.
