RHT Model Traveling Barrel Type Sucker Rod Pumps
RHT model traveling barrel sucker rod pump description
RHT model traveling barrel pump is another kind of sucker rod pump.It's different from the stationary barrel pump.
Allowable setting depth
In the early 1990s, an industry task group analyzed the stresses that react on a downhole rod pump. This was required to determine if there were recommended allowable loads that could be subjected to rod pumps of different types, sizes, and metallurgy. This group developed the burst, collapse, and axial-loading equations to determine these limits and the associated maximum recommended setting depth for sucker-rod lift pumps, [4] published in API RP 11AR.[1] The depth limitation and stresses on the downhole pump barrel and components should be considered when selecting the size, type, and metallurgy for a downhole pump.
