COMPRESSORS, PUMPS, AND PIPELINE FITTINGS
B. S. Zakharov
It is shown that when sucker-rod pumps are used, fluid leakage in seals of plunger-cylinder and valve pair
through hole and radial slot is proportional to the area of the flow section and is also dependent on the
shape of the latter. A new type of mechanical seal has been developed that reduces leakage significantly
and increases efficiency and nonfailure operating life of piston or plunger pumps.
The key operational parameters of sucker-rod pumps are delivery and nonfailure operating life that is generally
linked with a marked reduction or cessation of delivery. In most cases, this happens due to leakage in the worn-out joints of
seals of plunger-cylinder and valve pair, so determination of leakage through the seal and pressure loss (hydraulic resistance)
is of high importance.
