As shown in fig. 1, the utility model provides a self-priming pump set device, including water pump 10 and sealed water storage tank 8, the delivery port of water pump 10 is equipped with outlet pipe 12. The water inlet of water pump 10 passes through water pump inlet tube 9 and links to each other with water storage tank delivery port 3 and exhaust moisturizing pipe 5, water storage tank delivery port 3 is located the inside bottom of sealed water storage tank 8, the water inlet of exhaust moisturizing pipe 5 is located the inside upper portion of sealed water storage tank 8, the top of sealed water storage tank 8 is equipped with external water filling port 6 and water storage tank inlet tube 1.

The utility model discloses a theory of operation as follows: the utility model discloses pass through before the first start water filling port 6 by the external to water injection is in order to provide initial drawing liquid in the sealed water storage tank 8, will sealed water storage tank 8 closes water filling port 6 after filling completely. The water pump 10 is then activated, and the water pump 10 may pump the initial priming solution from the sealed water storage tank 8 at full power as a water source. Along with initial draw liquid water level in the sealed water storage tank 8 descends gradually, the negative pressure in the sealed water storage tank 8 strengthens gradually, and atmospheric pressure alright will wait to draw the water source in the facility (like the sump pit) and pass through the water storage tank inlet tube 1 is impressed in the sealed water storage tank 8. When the water in the facility to be pumped enters the sealed water storage tank 8 through the water storage tank water inlet pipe 1, the operation of the water pump 10 can be maintained. The utility model discloses the actual height of inhaling by sealed water storage tank 8's volume decision, because sealed water storage tank 8's volume is far greater than the volume of water pump 10 cavitys to the negative pressure that this produced can effectively solve conventional water pump 10 and inhale the problem of high not enough.

On the basis, in a specific embodiment 1, as shown in fig. 1, the bottom end of the exhaust water replenishing pipe 5 is connected with the water storage tank water outlet 3 and the water pump water inlet pipe 9 which penetrates through the bottom surface of the sealed water storage tank 8 from bottom to top, and a check valve 4 is arranged between the water storage tank water outlet 3 and the water pump water inlet pipe 9.

In another embodiment 2, as shown in fig. 2, the water inlet of the exhaust water replenishing pipe 5 is opposite to the water outlet of the water inlet pipe 1 of the water storage tank. The exhaust moisturizing pipe 5 here is reducing exhaust moisturizing pipe, and its internal diameter plays grow gradually from the water inlet of exhaust moisturizing pipe, guarantees the water inlet internal diameter of exhaust moisturizing pipe is less than the pipe diameter of water storage tank inlet tube 1 makes unnecessary water can flow in sealed water storage tank 8.

In another embodiment 3, as shown in fig. 3, the exhaust water replenishing pipe 5 upwardly penetrates through the top surface of the sealed water storage tank 8 and then is connected with a water inlet pipe 9 of a water pump, and a valve 7 is arranged between the water outlet 3 of the water storage tank and the water inlet pipe 9 of the water pump. The main body part of the exhaust water replenishing pipe 5 is arranged outside the sealed water storage tank 8 in the embodiment, so that the structure is simpler and the inspection and maintenance are convenient.
