Classification Of Agricultural Water Pumps
Agricultural water pump is a kind of agricultural machinery, and the water pump is a machine that transports liquid or pressurizes the liquid. According to the working principle and structural characteristics of the main working parts, the first type is the vane pump, which relies on the rotating impeller to work with centrifugal force or […]
Positive Displacement Pumps Are
Positive displacement pumps are the pumps that provide flow and pressure to the outside, which are conventional pumps. A negative displacement pump is a hydraulic motor that runs on external pressure and flow. Positive displacement pumps are self-charging. Unlike centrifugal or turbo pumps, flow is constant regardless of system pressure drop. Structural Characteristics and Application […]
Use of positive displacement pump
Hydraulic pumps are the heart of every hydraulic system, and they have many unavoidable responsibilities that help improve system performance. Pumps play an important role in converting mechanical energy into useful hydraulic energy. You can find a variety of hydraulic pump types for a variety of applications. Based on displacement, pumps are mainly divided into […]
Principle and basis of pump selection
Selection principle Make the type and performance of the selected pump meet the requirements of process parameters such as device flow, head, pressure, temperature, cavitation flow, and suction. The requirements for the properties of the medium must be met.For pumps that transport flammable, explosive, toxic, or precious media, reliable shaft seals or leak-free pumps are […]
The difference between a dynamic pump and a positive displacement pump
Positive displacement pump The positive displacement pump relies on the reciprocating or rotating motion of the working element in the pump cylinder to make the working volume increase and decrease alternately to realize the suction and discharge of the liquid. The positive displacement pump whose working element performs reciprocating motion is called a reciprocating pump, […]
The positive displacement pump
The positive displacement pump relies on the reciprocating or rotating motion of the working element in the pump cylinder to make the working volume increase and decrease alternately to realize the suction and discharge of the liquid. The positive displacement pump whose working element performs reciprocating motion is called a reciprocating pump, and the one […]
