Abstract

The invention provides an oil pumping unit test load simulation device. The oil pumping unit test load simulation device comprises a hydraulic motor, a winding drum and a hydraulic control system, thehydraulic motor is in transmission connection with the winding drum, and the free end of a flexible rope on the winding drum is connected with a beam hanger of a pumping unit to be tested; and the hydraulic control system comprises a descending oil way used for simulating the load of the oil pumping unit in a down stroke and an ascending oil way used for simulating the load of the oil pumping unit in an up stroke. The oil pumping unit test load simulation device is simple in structure, low in power consumption and capable of simulating oil well change loads, can achieve automatic control, andcan more conveniently adjust test loads.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery, in particular to a test load simulation device for an oil pumping unit. Background technique [0002] At present, in the oil production system of the oil field, the pumping unit is used as a part of the surface oil production system, and the annual usage is very large. In order to ensure the good reliability and long service life of the pumping unit, whether it is a beam pumping unit Or the beam pumping unit without beam all needs to carry out load test or type test inspection after the design and manufacture are completed. At present, the method of hanging heavy objects at the suspension point of the pumping unit is usually tested. The process is complicated, the operation is inconvenient, and the load change working conditions of the pumping unit cannot be simulated. Contents of the invention [0003] The purpose of the present invention is to provide a pumping unit test load sim...
