API Heavy Wall RHAC RHAM Type Rod Insert Pump
Heavy wall RHAC RHAM type rod insert pump description:
API-RHAC, Rod, Stationary Heavy Wall Barrel, Cup Top Anchor Pump
API-RHAM, Rod, Stationary Heavy Wall Barrel, Mechanical Top Anchor Pump
Comparing with conventional tubing pump, The API sucker rod pump
and tubing Pump has better performance in corrosion resistance &
antifriction aspects.
Plunger of it is nickel plated on alloy base, inside wall of barrel
is plated hard cadmium, key parts, such as valve hood, valve ball,
are made of materials with excellent mechanical performance and
corrosion resistant property. Compared with conventional pump, the
series of pump has a longer working life.
There are two different barrels and plungers in series connection
pump. According to the theory of hydraulic feedback, during the
down stroke, a downward force is formed to overcome the friction
between the viscous crude and the sucker rod, thus improving the
load condition on the sucker rod and decreasing and eliminating the
disconnection and break of
the sucker rod. The pump applies to the wells of oil viscosity less
than 4,000mPa*s(50℃),the wells with thin oil and the viscous
oil wells without thermal recovery conditions.
