Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, and more specifically, to a water pump self-priming auxiliary device. Background Art

[0002] The impact of insufficient water supply for water pumps includes the following three parts:

[0003] 1. Reduced operating efficiency. If the water pump lacks water, the operating efficiency of the pump will decrease. The pump needs water to cool the motor and bearings when running to ensure the normal operation of the pump system. When the water source is insufficient, the pump will overheat, thereby reducing the efficiency of the pump.

[0004] 2. Damage to the pump's operating system. If the pump is used for a long time without water, the pump's operating system will be damaged, such as the motor and bearings. When the motor overheats, the motor coil may be burned out, and the bearings may be damaged because they are not fully lubricated.

[0005] 3. Shorten the service life. Lack of water source for the water pump may accelerate the aging and damage of the pump, thus shortening the service life of the pump. This will not only lead to losses in maintenance costs, but also affect the normal life of users.

[0006] There are three existing solutions:

[0007] 1. Increase the water source. When the water source of the water pump is found to be insufficient, the water source should be increased in time. The water supply can be increased by installing corresponding pipes or setting up a water tank near the water source.

[0008] 2. Use a double pump. If a single pump cannot meet the flow and head requirements, a double pump is recommended. A double pump is composed of multiple pumps in parallel, which can achieve high flow and high head water level increase.

[0009] 3. Regular maintenance. Regular maintenance of the water pump is also very important to avoid a lot of losses caused by improper operation. During regular maintenance, you should pay attention to cleaning the internal parts of the pump, especially the bearings and motor parts, to ensure the stable operation of the pump.

[0010] In summary, insufficient water source for water pumps will undoubtedly have many impacts on the use of water pumps, and will have a negative impact on the operating efficiency and service life of the pumps. Therefore, it is necessary to replenish water sources in time, use double water pumps, and perform regular maintenance to ensure the normal operation of the pumps and extend their service life.

[0011] However, increasing water sources is time-consuming and labor-intensive, and using double water pumps or regular maintenance increases costs. Is there a simpler and more convenient way to ensure that the water pump is never short of water? This is a problem that needs to be solved at present. Summary of the invention

[0012] In view of this, the present invention proposes a water pump self-priming auxiliary device, including a first water pipe 10, a second water pipe 20, a third water pipe 30, a return pipe 40, a first water tank 50, a second water tank 60 and a water pump 70. When the water pump 70 is started, the water of the water source passes through the first water pipe 10, the first water tank 50 and the water pump 70 in sequence through the suction force of the water pump 70 and is discharged from the second water outlet 61 of the second water tank 60. When there is no water in the water source, the water in the first water pipe 10 is completely pumped into the first water tank 50, and then the water in the first water tank 50 is discharged. All of the water is pumped into the second water tank 60 through the water pump 70 until there is no water entering the second water tank 60. The second water tank 60 is full, i.e., no water is discharged from the second water outlet 61. However, due to the action of the reflux pipe 40, part of the water in the second water tank 60 flows back to the second water tank 60 until the water levels of the first water tank 50 and the second water tank 60 are level. Then, since the first water tank 50 is full of water, the water pump 70 pumps all the water in the first water tank 50 into the second water tank 60, and so on. This reciprocating process ensures that the water pump 70 will never be short of water. The operation is simple, convenient and low-cost.
