India hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder
(India stroke adjustable cylinder,produced by Hebei Hengyu company）
stroke adjustable cylinder are widely used in India，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed stroke adjustable cylinder for customers from India.
The body of the stroke adjustable cylinder on the processing process requirements: the body of the stroke adjustable cylinder is an important and essential part of the stroke adjustable cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the stroke adjustable cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
Piston stroke adjustable cylinder is widely used in hydraulic transmission. When the stroke adjustable cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the stroke adjustable cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the stroke adjustable cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.
The stroke adjustable cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the stroke adjustable cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the stroke adjustable cylinder wall due to the stiffness and the weight of the parts, causing scars.
The material of the sliding part of the stroke adjustable cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
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.
