A positive-displacement pump (lifting pump) comprises a pump housing with a pump chamber having an inlet and an outlet passage controlled by an outlet check valve; a displacement member which delimits the pump chamber in one direction of movement of the displacement member and which is reciproc...

Thus a positive displacement type flow meter which is connected to the motor and works as a pump, transports the gas from the upstream side to the downstream, so as to nullify the difference of pressure. The servo performs an ... T Isobe,S Fukumoto - 《Automatic Control》 被引量: 0发表...
Which of the listed pumps is NOT a positive displacement pump?; entrifugal pump;Reciprocating pump; Gear pump;Rotary pump
A positive displacement (PD) flow meter is a type of flow meter that provides high accuracy (±0.1% of actual flow rate in some cases) and good repeatability (as high as 0.05% of reading). These meters do not require a power supply for their operation and do not require straight ...
The lubricating arrangement and/or the control and actuating arrangements of shift gears, in particular automatic and infinitely variable shift gears, are supplied with pressure medium by a positive-displacement pump. The positive-displacement pump is driven at the speed of rotation of a driving motor...
A positive displacement rotary pump (11), such as a gerotor pump, has an axial housing inlet opening (25) with an outer radial edge (37) extending inside the radial outer extent (39) of the rotating fluid in the pump such that, at design speed, the fluid pressure due to rotation of ...
