Fig. 2 is this utility model hydraulic oil Anti-lost device connection diagram when job state, such as Fig. 2
Shown in, the hydraulic oil Anti-lost device in the application mainly solves the leakage stream of hydraulic oil during hydraulic system maintenance
Mistake problem.When changing oil pipe, valve member or other part directly connected with hydraulic oil container 11, such as, more
Change the hydralic hose 13 of hydraulic oil container 11 (3/4 volume is full of oil) upper connection, oil pipe, valve member etc., hydraulic pressure
Hydraulic oil in fuel tank 11 can occur with hydralic hose 13, oil pipe, the junction of valve member from hydraulic oil container 11
Reveal.
Use hydraulic oil Anti-lost device in the application can be prevented effectively from the generation of above-mentioned situation.Changing zero
Before part, by exhaling above the other end of the gs-oil separator 2 of this hydraulic oil Anti-lost device and hydraulic oil container 11
Haustorium adapter 12 is connected.Hydraulic oil container 11 ullage has certain space, has air in this space,
It is atmospheric pressure state.Start pressure generating means 1 again by control module 4, start pressure generating means 1 again
Air-breathing in space from hydraulic oil container 11 pasta, thus at the internal pasta of hydraulic oil container 11 and upper sealing panel
In cause negative pressure.Simultaneously as hydraulic oil container 11 is connected with pressure generating means 1 again, and between the two
Being provided with gs-oil separator 2, in hydraulic oil container 11, the gas between ullage and upper cover is pulled out so that in it
When the pressure in portion becomes negative pressure, the liquid in hydraulic oil container 11 will not be inhaled in negative pressure generating device 1.Pressure
Force measuring device 3 measures the pressure in the hydraulic oil container 11 obtained, and generates the signal of telecommunication, and control module 4 connects
Receive the signal of telecommunication, and send control signal to control negative pressure generating device 1 to negative pressure generating device 1.Work as hydraulic pressure
