The qualification of submersible oil pumps is the key to supporting the normal operation of the above equipment. Therefore, submersible oil pumps must undergo strict testing before leaving the factory. At present, in the submersible oil pump testing process, the test tooling is the key component to test whether the submersible oil pump can work normally. In the current tests, most tooling has the problems of occupying a large space area, not being convenient for flexible layout, and inconvenient installation. In addition, some test tooling has a complex structure, which makes it difficult for operators to operate, and has low test efficiency. It is impossible to quickly and effectively obtain the test results, the work efficiency is low, and the liquid pumped out of the submersible oil pump cannot be effectively recycled. In order to solve the above problems, there is an urgent need for a submersible oil pump test tooling with a simple and reasonable structure, small space occupation, and high use efficiency.

[0015] The present invention is further explained below in conjunction with the accompanying drawings and embodiments, which should not be used to limit the protection scope of the present invention. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0016] Combined with Figure 1-2 The submersible pump test fixture shown includes an oil tank imitation container 1, a manhole seat ring 2, a support 3, a submersible pump 4, an oil pipeline 5, a manual ball valve 6, a pressure gauge 7, a flow meter 8, a shock absorber 9, a shock absorbing elbow 10 and an oil outlet pipe 11.

[0017] Two holes are correspondingly arranged at both ends of the upper part of the oil tank imitation container 1; the manhole seat ring 2 is respectively arranged on the two holes of the oil tank imitation container 1, and a circle of flange is arranged on the upper end surface of the manhole seat ring 2; the support member 3 is respectively arranged on the flanges of the two manhole seat rings 2; the support member 3 is two parallel angle steels, and the two ends of the angle steels are respectively fixed to the flanges of the manhole seat ring 2 by bolts, and the distance between the two angle steels matches the outer diameters of the oil pipeline 5 and the oil outlet pipe 11, respectively, to ensure that the two side edges of the two angle steels are respectively clamped on the oil outlet pipe 11 and the oil pipeline 5.

[0018] The oil pipeline 5 is in an L-shaped structure, and the oil inlet end extends from between the support members 3 on the manhole seat ring 2 into the oil tank imitation container 1 and is connected to the submersible pump 4 through a flange, and the horizontal section is located above the oil tank imitation container 1; the manual ball valve 6 and the pressure gauge 7 are adjacently arranged on the horizontal section of the oil pipeline 5, and the oil outlet end of the horizontal section of the oil pipeline 5 is connected to the inlet end of the flow meter 8 through the shock absorber 9, and the outlet end of the flow meter 8 is connected to the oil outlet pipe 11 through the shock absorber elbow 10, and the flow meter 8 is supported by a support block fixed on the oil tank imitation container 1; the oil outlet pipe 11 extends from between the support members 3 on the manhole seat ring 2 into the oil tank imitation container 1.

[0019] Preferably, the shock absorber 9 is a rubber flexible joint.

[0020] Before the test, the oil pipeline 5 is disassembled from the manual ball valve 6, and the submersible pump 4 is connected to the oil inlet end of the oil pipeline 5 through a flange. Then, the submersible pump 4 is placed into the oil tank imitation container 1 from the manhole seat ring 2, and the oil pipeline 5 is bolted to the manual ball valve 6.

[0021] During the test, the submersible pump 4 is started, and the submersible pump 4 draws liquid from the oil tank imitation container 1, passes through the oil pipeline 5 and the flow meter 8, and then returns to the oil tank imitation container 1 from the oil outlet pipe 11 to realize liquid circulation; by adjusting the opening and closing degree of the manual ball valve 6, the pressure in the pipe is adjusted to allow the submersible pump 4 to reach the specified head, for example, the head of 0.1MPa is 10 meters; observe the pressure gauge 7 to see whether the submersible pump 4 can reach the specified rated flow rate. If the pressure value does not meet the specified value, it means that the submersible pump 4 is not working properly; if the pressure value reaches the designed value, it means that the submersible pump 4 is working normally and the submersible pump 4 is qualified; at the same time, the liquid pumped out by the submersible pump 4 is monitored by the flow meter 8 to ensure that the submersible pump 4 is working normally and at the same time, detect that the pumped liquid meets the specified flow requirement.
