It can be seen that the utility model has the advantage of:
One, installation is located at piston both ends there are two leather bag is sealed, and one end forms closed fuel reserve tank with cylinder body, prevents
Only fluid is revealed, and the other end seals entire piston structure, prevents exterior materials from penetrating into fluid, pollutes fluid, is had more preferable
Sealing effect.
Two, it is provided with leading truck, ensures piston rod in external pressure change, guiding piston is transported along axis linear reciprocation
It is dynamic, avoid piston eccentric motion to sealing the abrasion of leather bag, while ensureing close to switch close to the opposite of unit and induction part
Displacement, it is ensured that sensor can work normally.
Three, piston rod is hollow circular tube structure, and built-in extension spring, piston rod is to spring with guide function, spring energy
Oil pressure is consistently greater than the pressure of external environment enough in guarantee compensation system, ensures that the oil in transmission device is only possible to outwardly ooze
Leakage, leaks into without external substance in transmission device, the damage for avoiding outside liquid from penetrating into transmission device to transmission device
It is bad.
Four, sensor is arranged separately in close to switch in a closed chamber, avoids the work of other factors interference sensor.
It is controlled by approach switch sensor, when realizing that pressure compensator leaks, the function of automatic repairing.It is close by monitoring
The open and-shut mode of switch, can detection device whether oil leak.
