Description
Technical Field
The invention relates to the field of measuring tools, in particular to a mobile oil well pump comprehensive performance test bed.
Background
With the increase of national oil field development projects, oil pumping units located all over the country are provided with more and more oil well pumps. The factors that affect the pumping efficiency during the operation of an oil well pump are many, and one of the most important factors is the influence of leakage. The actual displacement is reduced by the clearance between the piston and the bushing and by leakage between the valve and other connected parts. As long as the manufacturing quality and the assembling quality of the pump are ensured, the influence of the leakage is not large within a certain time after the pump is put down. But when the liquid is corrosive or sandy, the leak will increase rapidly due to corrosion and wear on the pump. Wax and sand deposits in the pump can cause the valve to be closed untight and even be blocked to seriously damage the operation of the pump. Under these circumstances, in addition to improving the structure and corrosion resistance of the pump, the method mainly adopts sand prevention and wax prevention measures and regularly checks the pump to maintain the normal operation of the pump.
