It is inserted into the lubricating oil that the first fluid-tight plate 81 stockpiles, to form liquid seal structure, as shown in Figure 6.The liquid seal structure with it is above-mentioned
The effect of sealing plate 63 substantially similarly, during piston rod 42 pushes lubricating oil, can prevent gas from entering the first oil
Sphere 3 is jacked up upwards in pipe 2, causes oil leak.
Preferably, the fixed point of the steel wire rope 61 and piston rod 42 is located at the middle part of 52 end face of piston rod.Described goes out
Hydraulic fluid port 413 is located at the bottom of first side 411, so that more lubricating oil can enter the second oil pipe 5.The fuel tank 1
Top be provided with lid 11, in order to which for use lubricating oil is added into mailbox 1.
The operation principle of the utility model, as shown in Fig. 1-Fig. 7：
When original state, vacuum pump 45 does not work, and spring 44 extends to longest, at this point, piston rod 42 is in stretching state
The end plate of limit position, piston rod 42 is located at the A points in Fig. 1, and A points are located at the left side of the first oil pipe 2 and 41 junction of cylinder barrel in figure；
Meanwhile steel wire rope 61 is in relaxed state, sphere 3 closes the first oil pipe 2.
When needing the make-up oil into gear-box 9, start vacuum pump 45, due to the inner wall of piston rod 42 and cylinder barrel 41
It is sealing, therefore, piston rod 42 can move under the action of negative pressure towards the second side 412, when the end plate of piston rod 42 moves
When to B points in figure, steel wire rope 61 is just changed into tension by relaxed state.
Later, vacuum pump 45 continues that piston rod 42 is driven to move to the second side, untilThe end plate of piston rod 42 is moved to figure In C points when, piston rod 42 is in the limit position of compressive state；During being moved to C points by B points, sphere 3 is by steel wire rope
Traction move up, open the first oil pipe 2, lubricating oil through the first oil pipe 2 flow into cylinder barrel 41 in, as shown in Figure 4.
Later, vacuum pump 45 works on certain time, and piston rod 42 is made to stop certain time in compressive state limit position,
So that enough lubricating oil flows into cylinder barrel 41.
Later, vacuum pump 45 is stopped, and under the action of spring 44, piston rod 42 can be moved to the first side 411, work as work
When the end plate of stopper rod 42 is moved to the points of the B in figure, sphere 3 again closes the first oil pipe 2, and lubricating oil stops flow into cylinder barrel 41；Together
When, liquid seal structure closes the first oil pipe 2, as shown in Figure 5 and Figure 6.
Later, spring 44 continues to press on piston rod 42 and is moved to the first side 411, until the end plate of piston rod 42 is moved to figure
In A points when, piston rod 42 again in stretching state limit position.
It is above-mentioned during being moved to A points by C points, the lubricating oil in cylinder barrel 41 can be pushed into the by the end plate of piston rod 42
Two oil pipes 5 simultaneously further flow into gear-box 9, are lubricated to the gear assembly in gear-box 9.
It should be noted, during piston rod 42 is moved to A points by B points, sphere 3 closes the first oil pipe 2, is
It prevents the air pressure across the first oil pipe 2 and sphere 3 is jacked up upwards and causes oil leak, it is therefore, specially described thin below sphere 3
The setting liquid seal structure in section 23, to prevent gas from being upward through the first oil pipe 2.
If gear-box 9 needs the lubrication Chuck Steak fed, it can be made by intermittent startup, closing vacuum pump 45
It obtains piston rod 42 to move back and forth, each adds to lubricating oil in gear-box.Specific startup, shut-in time need root
Setting is chosen according to the parameters such as bore of the size of cylinder barrel 41, the bore of the first oil pipe 2, the second oil pipe 5.The start and stop of vacuum pump 45 can
It is controlled by special control system.
