Internal blowout prevention tool pressure test device

Abstract

An inner blowout prevention tool pressure test device comprises a test rack, a location block, a tool location core, a top pressure oil cylinder, a 90-degree swing oil cylinder, an electrical controlcabinet, a high pressure hydraulic pump, an electric booster pump and solenoid valves. An outlet of the electric booster pump is connected with an inlet of a hydraulic pressure piston of the tool location core through a high pressure tube, an outlet of the hydraulic pressure piston is connected with a controller of an automatic control cabinet, and an outlet of the controller is connected with aninlet of the electric booster pump through the solenoid valve; first sets of inlets and outlets of the high pressure hydraulic pump are correspondingly connected with inlets and outlets of hydraulic cylinders arranged on two sets of symmetrically arranged tool location core slide rails, a second set of inlet and outlet of the high pressure hydraulic pump are correspondingly connected with an inletand an outlet of the top pressure oil cylinder, a third set of the top pressure oil cylinder is correspondingly connected with an inlet and an outlet of the 90-degree swing oil cylinder, and a plug cock wrench of the 90-degree swing oil cylinder is connected with a plug cock valve switching knob; and a high pressure oil hydraulic pump motor, an electric booster pump motor, the solenoid valves anda 90-degree swing oil cylinder control circuit are respectively connected with corresponding interfaces of the electrical control cabinet.

Description

technical field [0001] The invention relates to a pressure test device for an internal blowout prevention tool, which controls a power source through a programmable logic controller (PLC), and performs pressure tests on professional oil tools such as internal blowout prevention tools. Background technique [0002] At present, most manufacturers in my country use simple threaded pressure test tooling for internal blowout prevention tools. The connecting thread is tightened to deform the sealing ring to achieve the sealing of the end face of the internal blowout prevention tool. This pressure testing method not only has low pressure testing efficiency and high labor intensity, but also has potential safety hazards. With the continuous development of pressure test work and the increase of workload, some manufacturers have begun to study simple and efficient pressure test equipment, but there are problems such as difficulty in automatic centering of tools, easy damage of sealing...
