(Brazil reset cylinder,produced by Hengyu Hydraulic Co., Ltd）
reset cylinder are widely used in Brazil，because of long service life，smooth movement，high work efficiency.So our company has designed reset cylinder for customers from Brazil.
When the reset cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
The material, shape and compression of the reset cylinder seal have a great impact on the service life and work efficiency of the reset 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.
reset cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the reset cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the reset cylinder. c. The reset cylinder seal is extruded, if the O-ring is obviously extruded at the reset cylinder seal, replace the reset cylinder seal.
The coordination of the sliding parts of the reset cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
Why is a light cylinder less productive than a heavy cylinder at the same oil pressure?
f=ps Under the same pressure, the larger the area, the greater the output, but the maximum pressure can not exceed the system engineering pressure of the cylinder!
How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.
