Horizontal testing system of oil-submerged pump

Abstract

The invention provides a horizontal testing system of an oil-submerged pump. According to the technical scheme of the horizontal testing system, one side of a three-phase asynchronous motor (1) is connected with a torque rotating speed sensor (2) and connected with a coupling (3) through a shaft (15); a high-pressure pump discharge opening (4) is connected with the oil-submerged pump (8) in parallel; a height adjusting handle (12) is arranged on the high-pressure pump discharge opening (4); the bottom of the height adjusting handle (12) is connected with a test bed base (11); the oil-submerged pump (8) is provided with an oil-submerged pump suction inlet (14); an upper pipeline of the high-pressure pump discharge opening (4) is connected with electromagnetic flowmeters (5) through a pressure sensor (16); the electromagnetic flowmeters (5) are connected with switching valves (6); the switching valves (6) are connected with a storage tank (9) through a high-pressure pipeline (7); the storage tank (9) is connected with the oil-submerged pump suction inlet (14); the other side of the three-phase asynchronous motor (1) is connected with a power distribution cabinet (10); and the power distribution cabinet (10) is connected with a control terminal (13). The horizontal testing system provides accurate data for testing of the pump efficiency of a centrifugal pump.

Description

technical field [0001] The invention relates to the technical field of submersible oil pumps, in particular to a horizontal test system for submersible oil pumps. Background technique [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. Results matter. Contents of the invention [0003] The purpose of the present invention is to provide a submersible pump level ...
