It can also use clean water to pressurize and perform functional tests on the production logging blowout prevention equipment. After the blowout prevention equipment is normally connected and fixed, it is convenient for maintenance; the control panel 1 is used to control the switch of the pressurization solenoid valve 4 and the pressure relief solenoid valve 8. The high-pressure pump 5 is pressurized through the high-pressure pipeline, and the blowout prevention equipment installed on the connection seat 7 can be pressurized to perform functional tests.

[0036] When the function of the equipment after maintenance is to be tested, water is added through the manual switching valve on the control panel 1, and the water adding pump 10 is controlled to add water to the blowout prevention equipment. After the water is full, the pressure pump is selected, the electromagnetic valve core is opened, and the high-pressure pump 5 is controlled to pressurize the equipment to be tested, and the sealing and other functions of the blowout prevention equipment are tested. After the test is completed, the pressure relief electromagnetic valve 8 is controlled to open and release the pressure, the pressure sensor 2 is used to observe the pressure, and the safety valve 3 prevents the pressure from being too high. If large-scale equipment needs to be tested externally, it can be connected externally from the external interface 6.
