Abstract

The invention aims to solve technical problems of providing an oil pump tightness performance test and leakage loss detection system and test device, the oil pump tightness performance test and leakage loss detection can be switched conveniently, the degree of mechanization is high, and multiple oil pumps can be detected simultaneously. Since an overflow valve is arranged, the leakage loss detection state can be switched without the adjustment of a high pressure pump, the adaptability of the system is improved, and the oil pump tightness performance test and leakage loss detection can be switched conveniently since the system matches with a first switch valve and a second switch valve. After testing, an unloading valve is adopted to relief pressure, impact caused by system pressure change can be reduced, and the system safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of oil well pump performance detection, in particular to an oil well pump sealing performance test, a leak detection system and a matching test device. Background technique [0002] The oil well pump is used to raise the underground oil to the ground. After the oil well pump leaves the factory or is overhauled, it needs to carry out the sealing performance test and the leakage detection to judge the product quality. There are many standards in the industry to regulate it, such as: GB / T 18607, SY / T 5188, SY / T 5872, SY / T 5059, etc. Around this demand, there are various detection methods and systems in the industry. The "Oil Well Pump Tightness and Leakage Test Bench" proposed on pages 63 to 74 of "Oilfield Surface Engineering (OSE)" in April 1994 is one of the earlier detection systems in China. The detection function of the oil well pump is relatively simple and the automation level is low. "Petroleum Mach...
