For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0020] The following refers to the attached Figure 1 to the attached Figure 3 to describe the combined explosion-proof electric submersible pump of the present invention.

Specifically, through the collaborative work of multiple pumps, the speed and efficiency of liquid transmission are significantly improved. The system design avoids the bottleneck problem of the traditional series system. Through the parallel system, the overall performance is optimized, the structure is compact, and it is suitable for the efficient transmission of ultra-large flow liquids.

[0022] Preferably, as Figure 2 shown, a guide fixing piece 4 is arranged in the pump chamber 1 to evenly distribute the plurality of pump bodies 3, and avoid the problems of too fast or too slow local flow velocity caused by uneven distribution of the pump bodies 3.

[0023] Preferably, the guiding and fixing piece 4 includes a central fixing port 401 for placing the pump body 3 and a peripheral fixing port 402. A positioning hole 403 is arranged beside the peripheral fixing port 402. Removable positioning rods 404 are evenly distributed on the periphery of the central fixing port 401. The positioning rods 404 match the positioning holes 403. The design of the positioning rods 404 and the positioning holes 403 facilitates the quick installation and adjustment of the pump body 3.

[0024] Preferably, the peripheral fixing port 402 includes a first positioning port 100, a second positioning port 200, a third positioning port 300 and a fourth positioning port 400. The distances from the first positioning port 100, the second positioning port 200, the third positioning port 300 and the fourth positioning port 400 to the central fixing port 401 are the same. Positioning holes 403 for inserting the positioning rods 404 are arranged beside the first positioning port 100, the second positioning port 200, the third positioning port 300 and the fourth positioning port 400. The connection line between the first positioning port 100 and the third positioning port 300 is perpendicular to the connection line between the second positioning port 200 and the fourth positioning port 400. The design of the four symmetric positioning ports further optimizes the uniform distribution of the pump body 3, and a parallel system of four pumps or five pumps can be realized, improving the stability and transmission efficiency of the system.

[0025] Preferably, it further includes a fifth positioning port 500, a sixth positioning port 600, a seventh positioning port 700 and an eighth positioning port 800. The distances from the first positioning port 100, the fifth positioning port 500 and the sixth positioning port 600 to the central fixing port 401 are the same. Positioning holes 403 for inserting the positioning rods 404 are arranged beside the first positioning port 100, the seventh positioning port 700 and the eighth positioning port 800.

The included angles between the connection lines from the third positioning port 300, the seventh positioning port 700 and the eighth positioning port 800 to the central fixing port 401 are 120 degrees. Specifically, by adding more positioning ports, the arrangement density of the pump body 3 is further optimized. A parallel system of three pumps or four pumps can be realized. At the same time, in cooperation with the first positioning port 100, the second positioning port 200, the third positioning port 300 and the fourth positioning port 400, a parallel system of up to nine pumps can be realized, significantly improving the overall efficiency and stability of the system.

[0026] Preferably, an arc-shaped baffle 405 is provided at one end of each peripheral fixing port 402 away from the positioning hole 403. The design of the arc-shaped baffle 405 can prevent liquid impact or overflow, protect the pump body 3 from mechanical damage, and cooperate with the positioning rod 404 inserted into the positioning hole 403 to guide and fix the pump body 3 through the arc-shaped baffle 405 and the positioning rod 404, facilitating the installation of the pump body 3.

Two 120-degree and one 90-degree can also be selected to form three lines with an included angle of 120 degrees, so as to arrange three pump bodies 3 around the perimeter and one pump body 3 in the center.

[0028] Meanwhile, it can be understood that the detachable positioning rods 404 evenly distributed on the periphery of the central fixing port 401 also guide and fix the pump body 3 installed in the central fixing port 401.
