(Indonesia press machine hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
press machine hydraulic cylinder are widely used in Indonesia，because of long service life，smooth movement，high work efficiency.So our company has designed press machine hydraulic cylinder for customers from Indonesia.
The press machine hydraulic cylinder should be vented: when the press machine hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the press machine hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the press machine hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the press machine hydraulic cylinder, the oil is best entered and discharged from the highest point of the press machine hydraulic cylinder. press machine hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.
How the cavitation of the press machine hydraulic cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the press machine hydraulic cylinder, resulting in corrosive damage to the parts.
When installing the press machine hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the press machine hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the press machine hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the press machine hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the press machine hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
The meaning of the press machine hydraulic cylinder model marked by the press machine hydraulic cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the press machine hydraulic cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the press machine hydraulic cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.
Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
