The beneficial effects of the utility model are: the hydraulic pump structure of VFC of the present utility model is simple, connects the frequency variator module at drive motor, and it is more accurate to control, and has improved working efficiency, has reduced simultaneously the energy loss of drive motor, increases the service life.
Description of drawings
Fig. 1 is the structural representation of oil hydraulic pump one preferred embodiment of the utility model VFC;
The mark of each parts is as follows in the accompanying drawing: 1, the pump housing, 2, fuel tank, 3, liquid level display meter, 4, alarm, 5, spring, 6, plunger, 7, driving cam, 8, drive motor, 9, the frequency variator module, 91, drive chip, 92, sensor, 93, energy-saving chip, 10, solenoid electric valve, 11, automatic controller.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model is embodiment comprise:
A kind of oil hydraulic pump of VFC comprises: the pump housing 1, the pump housing 1 outer installment has fuel tank 2, is connected with liquid level display meter 3 and alarm 4 on the fuel tank 2.Liquid level display meter 3 can be measured and shows that when fuel tank 2 inner fluid were lower than certain value, alarm 4 can alarm the fluid of fuel tank 2 inside.
Be provided with solenoid electric valve 10 on the pipeline of the pump housing 1 outside connection fuel tank, can control the conveying of fluid.Be provided with automatic controller 11 on the solenoid electric valve 10, control precisely need not manual operation, has accelerated control rate, has improved control efficiency.
The plunger 6 that the pump housing 1 inside is provided with spring 5 and is connected with spring 5, plunger 6 bottoms are connected with driving cam 7, connect drive motor 8 on the driving cam 7.
Be connected with frequency variator module 9 on the drive motor 8, frequency variator module 9 comprises driving chip 91, sensor 92 and energy-saving chip 93.Wherein, drive chip 91 connecting sensors 92, sensor 92 connects drive motor 8.When fuel tank 2 inner fluid reserves are inadequate, drive chip 91 drives drive motor 8 by sensor 92 work.
Described energy-saving chip 93 connects drive motor 8, is electric connection between energy-saving chip 93 and the drive motor 8.Energy-saving chip 93 can reduce the energy loss of drive motor 8, increases the service life.
The working procedure of the oil hydraulic pump of the utility model VFC is:
Drive motor 8 drives driving cam 7 and rotates, and driving cam 7 promotes plunger 6 and moves upward, and the sealed volume between plunger 6 and the pump housing 1 reduces at this moment, and fluid is extruded from sealed volume, is discharged to fuel tank 2 through solenoid electric valve 10 again;
When driving cam 7 rotates again, spring 5 forces plunger 6 downward, forms certain degree of vacuum, and the fluid in the fuel tank 2 enters sealed volume under the atmospheric pressure effect.Driving cam 7 makes plunger 6 continuous liftings, the pump housing 1 continuous oil suction and oil extraction.
The beneficial effect of the oil hydraulic pump of VFC of the present utility model is:
Simple in structure, connect the frequency variator module at drive motor, it is more accurate to control, and has improved working efficiency, has reduced simultaneously the energy loss of drive motor, increases the service life.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
