Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
Piston pump compared to a plunger pump. A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. [1] Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without adversely affecting flow rate.
NOV's two main predecessors, Oilwell Supply and National Supply, were founded in 1862 and 1893, respectively. These two companies manufactured and distributed pumps and derricks. In 1930, United States Steel acquired Oilwell Supply. In 1958, Armco Steel merged with National Supply. In 1987, National Supply merged with USS Oilwell to become ...
A single 66" diameter pump was installed at Del Rio, Texas in 1914. [10] This was constructed by the Humphrey Gas Pump Co. of Syracuse, NY, who had licensed the Humphrey patents. [5] A single Humphrey pump was installed at a Sewage works in Southend-on-Sea, England during 1914. The pump had head of 65 ft at a capacity of 198,000 gallons per day.
The major problem of screw pumps is that the hydraulic reaction force is transmitted in a direction that's axially opposed to the direction of the flow. There are two ways to overcome this problem: put a thrust bearing beneath each rotor; create a hydraulic balance by directing a hydraulic force to a piston under the rotor. Types of screw pumps:
A diagram of a pumpjack. A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1]It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface.
