India hydraulic cylinder,hydraulic lift cylinder manufacturer,hydraulic lift cylinder
(India hydraulic lift cylinder,produced by Hebei Hengyu company）
hydraulic lift cylinder are widely used in India，because of smooth movement，no need for deceleration device，long service life.So our company has designed hydraulic lift cylinder for customers from India.
Causes and countermeasures of oil hydraulic lift cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the hydraulic lift cylinder will lead to premature wear of the piston seal, replace the piston seal; If the hydraulic lift cylinder is visibly scarred, the hydraulic lift cylinder must be replaced. It can be pressurized at one end of the hydraulic lift cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most hydraulic lift cylinder piston drift may not come from the hydraulic lift cylinder, the above method to determine the hydraulic lift cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
The viscosity of the working oil used in the hydraulic lift cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
The scar on the sliding surface of the hydraulic lift cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the hydraulic lift cylinder wall. Therefore, before installation, these scars must be fully repaired.
hydraulic lift cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the hydraulic lift cylinder head itself is the guide sleeve of the piston rod, the hydraulic lift cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the hydraulic lift cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.
What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.
