Saudi Arabia hydraulic cylinder,cargo elevator hydraulic cylinder manufacturer,cargo elevator hydraulic cylinder(Saudi Arabia cargo elevator hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
cargo elevator hydraulic cylinder are widely used in Saudi Arabia,because of no need for deceleration device,long service life,smooth movement.So our company has designed cargo elevator hydraulic cylinder for customers from Saudi Arabia.
When the cargo elevator hydraulic cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the cargo elevator hydraulic cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil cargo elevator hydraulic cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical cargo elevator hydraulic cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the cargo elevator hydraulic cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.
When purchasing the cargo elevator hydraulic cylinder, try to clarify the following parameters of the cargo elevator hydraulic cylinder: A. cargo elevator hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or cargo elevator hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right cargo elevator hydraulic cylinder type can be found accurately and quickly.
When the cargo elevator hydraulic cylinder is in use, ensure that the cargo elevator hydraulic cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.
Because of the slightly complex structure of the buffer cargo elevator hydraulic cylinder, sometimes there will be problems, such as when the cargo elevator hydraulic cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.
Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.
By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
