Close to the induction part of switch 10, become closed state close to switch 10 from normally open, oil inlet is opened, and fuel tank is filled for compensation
Repairing is put, piston 2 is pushed to move down, drive piston rod 4 and is moved down close to unit sleeve 9, it is separate close to unit sleeve 9
Close to switch 10, when being completely disengaged close to unit sleeve 9 close to the induction part of switch 10, close to switch 10 by closed state
Off-state is converted to, oil inlet is closed, and realizes the automatic repairing of compensation device.In the work progress of equipment, operating personnel
Can always it be located close to switch by judging whether equipment transmission device occurs oil leakage phenomenon close to the folding condition of switch 10
When closed state, you can oil accident occurs for discovering device.
It when pressure compensator works normally, is off close to switch, oil inlet is in closed state, ensures to mend
System is repaid as closed loop states, the piston drives piston rod and close to unit sleeve along piston rod in external pressure change
The pressure compensation of transmission device is realized to straight reciprocating motion.
When permeability or oil leak occur for compensation device or transmission device, being hidden close to unit sleeve on piston driving piston rod
Gear is closed close to after inductive switching part close to switch, and oil inlet is opened, and fuel tank is compensation device repairing, with compensation device
The supplement of fuel reserve tank fluid pushes piston driving separate close to inductive switching part close to switch sleeve, when sleeve is not blocking
It during induction part, is disconnected close to switch, oil inlet is closed, and realizes the automatic repairing function of pressure compensator.
Operating personnel can be judged by the folding condition monitored close to switch compensation device and transmission device whether oil leak, when
When becoming normally off from normally open close to switch, you can infer that compensation device or transmission device have occurred for some reason
Fluid is revealed, this leakage can not realize the oil pressure balance of system by automatic repairing function, need immediately to check device,
Avoid accident.
It can be seen that the advantage of the invention is that:
First, there are two sealing leather bags for installation, and respectively positioned at piston both ends, 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.
2nd, leading truck is provided with, ensures piston rod in external pressure change, guiding piston is transported along axis linear reciprocation
It is dynamic, piston eccentric motion is avoided to sealing the abrasion of leather bag, while is ensured close to switch close to the opposite of unit and induction part
Displacement, it is ensured that sensor can work normally.
3rd, 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, and outside liquid is avoided to penetrate into damage of the transmission device to transmission device
It is bad.
4th, 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.
5th, cylinder body is formed by three cylinders with screw-pressing, convenient for maintenance clean and replaces sealing leather bag.
It is readily apparent that above description and record is only illustrated in the disclosure being not intended to be limiting of the invention
Appearance, application or use.Although describing in embodiment and embodiment being described in the drawings, the present invention does not limit
By attached drawing example and be described as in embodiment it is now recognized that optimal mode to implement the particular case of the teachings of the present invention
