Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Wherein: 1 is vacuum pump, 2 is vacuum meter, and 3 is pipe joint, and 4 is vacuum cup, and 5 is fuel inlet ball check valve, and 6 is snap joint, and 7 is oil extraction ball valve, and 8 is vacuum interface, and 9 is oil-feed interface, and 10 is oil extraction interface.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention includes vacuum pump 1, vacuum meter 2, vacuum cup 4, fuel inlet ball check valve 5 and oil extraction ball valve 7, and wherein vacuum cup 4 is the hermetic container of hollow, is made up of transparent acrylic material, vacuum cup 4 is carved with scale, it is simple to measure the hydraulic oil in vacuum cup 4.
The top of vacuum cup 4 has vacuum interface 8, it is ensured that in work process, hydraulic oil does not enter in vacuum pump 1.The bottom of vacuum cup 4 has oil extraction interface 10, and the wall of cup between vacuum interface 8 and oil extraction interface 10 has oil-feed interface 9.Vacuum interface 8 can be opened in the centre at vacuum cup 4 top, and oil extraction interface 10 can be opened in the centre bottom vacuum cup 4, the longitudinal center line of vacuum interface 8 and oil extraction interface 10 can conllinear, and with the longitudinal center line conllinear of vacuum cup 4.Being mounted on the pipe joint 3 being connected with pipeline on vacuum interface 8, oil-feed interface 9 and oil extraction interface 10, vacuum pump 1 is connected with the pipe joint 3 on vacuum interface 8 by pipeline, and is provided with vacuum meter 2 on pipeline.Pipe joint 3 on oil-feed interface 9 is connected to pipeline, and the other end of this pipeline compensates system by snap joint 6 with underwater hydraulic and is connected, and this snap joint 6 can ensure that exhaust phase compensates liquid and do not result in the pollution to surrounding；Pipeline between oil-feed interface 9 and underwater hydraulic compensation system is provided with fuel inlet ball check valve 5, it is ensured that oil extraction stage air does not enter back into underwater hydraulic and compensates system.Pipe joint 3 on oil extraction interface 10 is connected with the container storing hydraulic oil by pipeline, and is provided with oil extraction ball valve 7 on pipeline.
Employing slope, the bottom design of vacuum cup 4, namely the bottom of vacuum cup 4 is downward-sloping from outside to inside, so both convenient cleaning, and the hydraulic oil that can guarantee that again between different underwater hydraulic compensation system does not pollute mutually；Because the design on slope can make the hydraulic oil in each vacuum cup 4 discharge, do not have residual, mutually would not pollute from the hydraulic oil in different underwater hydraulic compensation systems next time yet.
