Problems solved by technology

[0002] In the submersible electric pump test, the efficiency test of the centrifugal pump basically adopts the method of electric power calculation, and calculates the output torque of the motor by detecting the operating current of the motor and the timely power factor of the motor, as the input torque of the centrifugal pump, and the test It must be carried out in a special test well. Each test must install the whole unit and go down the well, and then test it. Due to the influence of the test environment, errors are prone to occur. The accuracy of the input torque of the centrifugal pump has a great influence on the pump efficiency test of the centrifugal pump. The result has an impact
