Electric submersible pump downhole test system – PHD test system: The PHD test system is developed and produced by CENTRILIFT in the United States, which can test the temperature and pressure of the pump hanger. Divided into two parts: downhole and ground, WS submersible electric pump (1) The downhole part is called a primary instrument: inductance coil, filter inductance capacitor, transformer, temperature relay, etc. It is installed at the tail of the motor. (2) The ground part is called the secondary instrument: generally placed in the transformer or control cabinet, switchboard, and connected to the main power line.

API standard WS submersible electric pump price—specific requirements of the control cabinet: the main and control circuits of the control cabinet should be subjected to a 50HZ withstand voltage test, no breakdown for 1min, and the effective value of the test voltage is 2 times the rated voltage plus 1000V. (1) The phase-to-phase and ground-to-ground insulation resistance of the main circuit of the WS submersible pump control cabinet of API standard should be greater than 500 megohms. (2) The insulation resistance of the control circuit of the control cabinet to the box should be greater than 2 megohms. Three-phase current display error shall not be higher than 5%.
The composition of API standard WS submersible electric pump – the role of oil and gas separator. (1) Acting as the suction port of the API standard WS submersible electric pump (2) Separating the gas in the oil well fluid, reducing the influence of the gas on the pump displacement, head, efficiency, etc. (3) The lower part is connected with the WS submersible electric pump protector, and the upper part is connected with the multi-stage centrifugal pump, which plays the role of transmitting power. If the oil well or hot spring well does not contain gas, the oil and gas separator can not be installed, and only the suction port can be selected. But for the sake of safety, it is generally recommended to install it to prevent the occurrence of unexpected situations and avoid causing greater losses.
