  • Detail

The application characteristics of reciprocating pump are summarized

① high efficiency and wide efficiency area

② it can reach a very high pressure, and the pressure change hardly affects the flow, so it can provide a constant flow

③ it has self-priming capacity and can transport liquid and gas mixtures. Specially designed ones can also transport mud, concrete, etc

the company tampered with the product quality inspection data ④ there are large pulsations in flow and pressure, especially in single acting pump. Due to the acceleration of piston movement and the discontinuity of liquid discharge, the pulsation is greater. It is usually necessary to set an air chamber on the discharge pipeline (sometimes on the suction pipeline) to make the flow more uniform. The use of double acting pump and multi cylinder pump can also significantly improve the non-uniformity of flow

⑤ low speed, large size and structure compared with centrifugal pump 3) wide useful experimental task space:> 680mm complex, special pump valve is required, and the manufacturing cost and installation cost are high. Piston pump is mainly used for water supply. Manual piston pump is a widely used domestic water pump. Plunger pump is used to provide high-pressure liquid source, such as high-pressure water supply of hydraulic press. It and piston pump can be used as drilling mud pump and oil well pump of 310000 T/a TDI technical transformation and capacity expansion project of oil mine. The diaphragm pump is especially suitable for conveying highly toxic, radioactive and corrosive liquids, precious liquids and liquids containing abrasive solids. Diaphragm pump and plunger pump can also be used as metering pump
