Australia hydraulic cylinder,lifter hydraulic cylinder manufacturer,lifter hydraulic cylinder
(Australia lifter hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
lifter hydraulic cylinder are widely used in Australia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed lifter hydraulic cylinder for customers from Australia.
lifter hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the lifter hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
lifter hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the lifter hydraulic cylinder is placed for a period of time, the lifter hydraulic 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.
When using the lifter hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the lifter hydraulic cylinder block. If the lifter hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the lifter hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the lifter hydraulic cylinder, so that the working efficiency of the lifter hydraulic cylinder is reduced.
The oil lifter hydraulic cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.
How to exhaust hydraulic cylinder?
Exhaust: The hydraulic system generally does not have exhaust, the use of the tank can exhaust, the oil operation will bring the gas back to the tank, and the tank can be communicated with the atmosphere. The gas will escape from the oil.
How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
