Further, a check valve is arranged between the self-priming pump interface and the suction hose;
furthermore, an adjusting bolt is arranged on the side of the vacuum pump bottom plate;
further, the vacuum pump rotating shaft and the self-priming pump rotating shaft are driven by a transmission mechanism;
furthermore, the transmission mechanism can adopt structures such as gear transmission, belt pulley transmission and the like;
furthermore, a protective cover is arranged outside the transmission mechanism.
The invention has the beneficial effects that: according to the self-priming pump, the butterfly valve and the check valve are arranged at the outlet of the self-priming pump, so that the medium can be effectively prevented from being refilled into the self-priming pump. Meanwhile, a check valve is arranged at the joint of the self-priming pump, so that the medium is prevented from being refilled into the vacuum pump, and the production efficiency is greatly improved.

Detailed Description
The invention will be further described with reference to the following figures and specific examples, but the scope of the invention is not limited thereto.
As shown in fig. 1 and 2, a self-priming pump comprises an inlet quick connector 1, a self-priming pump 2, a suction hose 3, a vacuum pump 4, a transmission mechanism 5, a butterfly valve 6, a check valve 7, an outlet quick connector 8, a protective cover 9, a self-priming pump connector 201, a self-priming pump bottom plate 202, a check valve 203, a suction inlet 401, a discharge port 402, an adjusting bolt 403 and a vacuum pump bottom plate 404, and is characterized in that: a check valve 203 is arranged between the self-priming pump connector 201 and the suction hose 3, so that the medium of the self-priming pump 2 is prevented from being refilled after the vacuum degree requirement is met, and the vacuum pump 4 is prevented from being polluted; the butterfly valve 6 is arranged at the outlet of the self-priming pump, the check valve 7 is arranged behind the butterfly valve 6, and the outlet quick connector 8 is arranged behind the check valve 7; the inlet quick connector 8 is connected with an inlet of the self-priming pump; the check valve 6 can effectively prevent the medium from flowing back into the self-priming pump 2; the vacuum pump 4 is provided with a suction inlet 401 and a discharge outlet 402, the self-priming pump interface 201 is connected with the suction inlet 401 through a suction hose 3, and the discharge outlet 402 is communicated with the atmosphere; an adjusting bolt 403 is arranged on the side of the vacuum pump bottom plate 404; the bottom plate 202 of the self-priming pump is fixed with the ground through bolts; the rotating shaft of the vacuum pump 4 and the rotating shaft of the self-priming pump 2 are driven by a transmission mechanism 5, and the transmission mechanism 5 can adopt structures such as gear transmission, belt pulley transmission and the like; and a protective cover 10 is arranged outside the transmission mechanism 5 to prevent the outside from interfering the operation of the transmission mechanism 5.
When the self-priming pump is in a working state, the vacuum pump 4 is coaxially linked with the self-priming pump 2 through the transmission mechanism 5, and stable flow and lift can be maintained. The unit motor operation drives the self priming pump shaft and rotates, drives the vacuum pump pivot simultaneously and rotates to make 2 inside vacuums that form of self priming pump, thereby make its work that can carry out the transmission liquid. Vacuum pump 4 operation this moment, suction inlet 401 is through the air that inhales in the suction hose 3 extraction self priming pump 2 for pump inlet department forms the vacuum, promotes self priming pump 2 and inhales the height and through the automatic exhaust pump line of discharge port 402 in the gas that persists. The butterfly valve 6 that 2 exits of self priming pump set up is shutting down and is being closed, and the check valve 7 that sets up behind the 6 valves of butterfly valve plays the secondary prevention effect simultaneously, prevents that the medium from recharging.
The present invention is not limited to the above-described embodiments, and any obvious improvements, substitutions or modifications can be made by those skilled in the art without departing from the spirit of the present invention.
