The internal self-priming booster pump provided in this embodiment is mainly used for boosting the second or more start; when the booster pump is started for the first time, the pressure in the water inlet cavity 4 and the pressure in the water outlet cavity 5 are relatively high, and at the moment, the interiors of the water inlet cavity 4 and the water outlet cavity 5 are filled by mixing water and air. When the booster pump is started for the second time, the water level in the water inlet cavity 4 is insufficient, so that water needs to be absorbed from the water inlet 11 and discharged from the water outlet. However, at this time, water is present in the water outlet pipe, so that the water outlet chamber 5 needs a larger pressure to discharge water (the water outlet pipe is air at the first start), and thus an exhaust structure is required to be designed to discharge water in the water outlet pipe into the water inlet chamber 4.
Working principle: according to the utility model, the impeller 3 is used for pressurizing, so that a mixture of water and air sequentially enters the water inlet cavity 4 from the water inlet 11 and the check valve 41; because part of air is sucked into the water inlet cavity 4 at the moment, the water inlet cavity 4 in the pump body 1 is in a semi-water state after air is introduced, the load is lightened, and the impeller 3 stops working; at this time, if the best self-priming effect is to be achieved, the whole pump cavity is required to be in a state of being full of water, so that the electromagnetic valve 9 is opened at this time, air in the water inlet cavity 4 is discharged, the electromagnetic valve is closed after the air is discharged, the pressure in the water inlet cavity 4 is reduced, the impeller 3 is started again, water and air are sucked again, but at this time, the water level is higher than the water level at the last time, the impeller 3 stops working again, the electromagnetic valve 9 is opened again, and the air is discharged again; then the impeller 3 is started again and circulates until the water pump load is stable, which means that the self-priming process is completed, the electromagnetic valve 9 is in a closed state, the pump body exits from the self-priming mode, and the pump body is changed into a normal mode.
Namely, the process is repeated mainly for improving the water level in the inner cavity of the pump body (improving the water level from the water inlet cavity 4 to the water outlet cavity 5), so that the water in the pump body gradually reaches the degree of being full of water, and the water pressure in the booster pump reaches the maximum at the moment; at this time, water in the water inlet cavity 4 can enter the water outlet cavity 5 through the water discharge flow channel 7 at the maximum water pressure and then is discharged, so that a common booster pump also has a self-priming function.
In the first embodiment, the booster pump is started, the water inlet pipe is connected through the water inlet 11, water is led into the water inlet cavity 4, the booster pump is started through the impeller 3, the mixture of water and air is sucked into the water inlet cavity 4, along with the rotation of the impeller 3, the water level in the pump body is increased (from the water inlet cavity 4 to the water outlet cavity 5) so as to gradually reach the degree of being full of water, when the water level sensing switch 10 detects that the water in the water inlet cavity 4 is full, the electromagnetic valve 9 is closed, the first fluid channel 81 and the second fluid channel 82 are separated, the water pressure in the booster pump reaches the maximum at the moment, the water in the water inlet cavity 4 enters the water outlet cavity 5 through the water drainage channel 7, the water outlet pipe is connected through the water outlet 12, and the booster pump discharges the water in the water outlet cavity 5.
In the second embodiment, when the booster pump is started and the water level sensing switch 10 detects that the water in the water inlet cavity 4 is not full after the booster pump finishes the water outlet operation, the electromagnetic valve 9 is opened, the first fluid channel 81 and the second fluid channel 82 are communicated, and the gas in the water inlet cavity 4 can be discharged to the outside through the fluid channel 8.
