Embodiment 1

[0029] Example 1, such as figure 1 As shown, the structure diagram of the pneumatic water pump of the first embodiment of the present invention is provided, which consists of a pump body 1, a water outlet pipe 2, an air inlet pipe 3, an air outlet pipe 4, a water inlet check valve 6, and a water outlet valve. Composed of directional valve 7, liquid level gauge, electric control valve A (10) and electric control valve B (11), the inside of the pump body 1 is the inner cavity 5, and the pump body 1 can be in the shape of a cylinder. When in use, the pump body 1 Stand upright. The lower end of the pump body 1 is provided with a water inlet check valve 6, the water inlet check valve only allows the external liquid (water) to enter the inner cavity 5, and does not allow the liquid in the inner cavity 5 to be discharged through the water inlet check valve 6 . The lower end of the water outlet pipe 2 extends into the bottom of the inner chamber 5, and the upper end of the water out...

Embodiment 2

[0043] Example 2, such as Figure 6 and Figure 7 As shown, the structural schematic diagram and the use state of the pneumatic water pump according to the second embodiment of the present invention are provided respectively, except that the connection form between the air inlet pipe 3 and the air outlet pipe 4 and the internal cavity of the pump body 1 is different, All the other structures and working conditions are the same as those in Embodiment 1.

[0044] In this embodiment, both the air inlet pipe 3 and the air outlet pipe 4 communicate directly with the inner chamber 5 of the pump body 1, and the electric control valve A (10) and the electric control valve B (11) are arranged near the pump body. The advantage is that when the electric control valve A is opened, the pressure gas can enter the inner chamber 5 of the pump body 1 through the inlet pipe 3 instantly; when the electric control valve B is opened, the gas in the pump body 1 can quickly flow from the outlet pip...

Embodiment 3

[0045] Example 3, such as Figure 8 and Figure 9 As shown, the structural schematic diagram and the use state of the pneumatic water pump of the third embodiment of the present invention are respectively provided. Compared with Embodiment 1, it does not use a circuit, and saves the electric control valves A, B and The upper and lower end liquid level gauges, but a two-position three-way valve 26, a floating ball 28 and a counterweight 29 are added. The common port of the two-position three-way valve 26 communicates with the inner chamber 5 of the pump body 1, and the intake pipe 3 communicates with the inner cavity 5 of the pump body 1. The first selection port of the two-position three-way valve 26 communicates, and the outlet pipe 4 communicates with the second selection port of the two-position three-way valve 26 . The two-position three-way valve 26 is provided with a connecting rod 27. When the connecting rod 27 is at the upper end position, the second selection port ca...

Abstract

The invention relates to an air pressure type water pumping method and a water suction pump. According to the method, a container is arranged in liquid, and a liquid inlet and a liquid outlet are formed in the container; when the liquid level rises to a certain height, the liquid is discharged through a pressure gas; and when the liquid drops to a certain height, the liquid enters the container again. The air pressure type water suction pump comprises a pump body, a water outlet pipe, an air inlet pipe, an air outlet pipe and a control circuit, and a water inlet one-way valve is arranged at the lower end of the pump body; the lower end of the water outlet pipe is provided with a water outlet one-way valve; and an electric control valve A and an electric control valve B are arranged on the air inlet pipe and the air outlet pipe respectively, and liquid level meters for detecting the liquid level is arranged in the inner cavity. According to the air pressure type water suction pump, the liquid in a lower position (a deep well) can be pumped to a higher position (a ground) by utilizing the pressure gas, a water pumping form of the existing deepwater submersible pump is changed, a motor and a pump body structure do not need to be adopted, the weight and the manufacturing cost of the water suction pump are reduced, the structure is simple and reasonable, the installation, the operation and maintenance are more convenient, beneficial effect is remarkable, and the water suction pump is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to a pneumatic water pumping method and a water pump, more specifically, to a pneumatic water pumping method and a water pump which use pressure gas to discharge liquid at a low position. Background technique [0002] The deep water submersible pump is used to pump out the liquid (water) in the deep water well, and its head can reach tens of meters or even hundreds of meters. The existing submersible pumps are all realized by the structure of the motor-driven pump body. Moreover, the operation and maintenance costs during installation and use are relatively high. [0003] As a storage method of energy, the pressure gas can do work externally. If the pressure gas can be used to discharge the liquid in a low position (such as a deep well), it will change the working mode of the existing deep water submersible pump, so that the submersible pump does not need to set the weight The larger motor does not need to lay cables, which can e...
