Jordan hydraulic cylinder,reset cylinder manufacturer,reset cylinder
(Jordan reset cylinder,produced by Hengyu Group）
reset cylinder are widely used in Jordan，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed reset cylinder for customers from Jordan.
When the initial action of the reset cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the reset cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.
Most of the failure of the reset cylinder is because there is a foreign body in the reset cylinder into the failure of the reset cylinder, the most problematic is that it is difficult to determine when the foreign body is into the reset cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
The scar on the sliding surface of the reset 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 reset cylinder wall. Therefore, before installation, these scars must be fully repaired.
The difference between the plunger reset cylinder and the piston reset cylinder is that the piston in the reset cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type reset cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.
How to limit cylinder push rod rotation?
In general, the push-rod rotation can be limited after the push-rod is connected to the pushed mechanism. For example, the push rod is hinged with the push mechanism, or the push mechanism itself is guided, which can limit the rotation of the push rod.
How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
