One of the major production costs of rod pumping is the cost of getting down and repairing sucker rods, pumps and tubing. Many wells are inefficient due to over-frequency detection of the pump, especially during shutdown. Recently, US researchers developed a low-sluicing pump to solve the above problems, making inefficient wells a long-term profit well. Minimum speed longest stroke Pumping faster, the more its reciprocating frequency, sucker rod to reach the fatigue limit faster. If the pumping...

Due to the structure of the displacement limit, it is generally considered gear pump can only be used as a constant flow hydraulic source. However, the attachment and threaded coupling valve scheme is effective in increasing its functionality, reducing system costs and increasing system reliability, and as a result, gear pump performance can approach that of costly, complex piston pumps. For example, installing a control valve directly on the pump controls the cost by eliminating piping between...
