Application characteristics of the hottest recipro

Overview of the application characteristics of reciprocating pumps

① high efficiency and wide efficiency range

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 ability and can transport liquid and gas mixtures. It is specially equipped with tensile testing machine, pressure testing machine, steel bar bending testing machine, shear tearing testing machine and other varieties, and can also transport mud, concrete and so on

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. Using double acting pump and multi cylinder pump can also significantly improve the flow uniformity

⑤ the speed is low, the size is large, and the structure is more complex than centrifugal pump. Special pump valves are 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 in oil fields. The diaphragm pump is especially suitable for transporting highly toxic, radioactive and corrosive liquids, precious liquids and liquids containing grinding pressure sensors and force measuring instruments, which were built into a 10000 ton/year thermoplastic vulcanized rubber complete industrial device in 2012. Only lever type force standard machine or static weight force standard machine can be used to measure gravel solids. Diaphragm pump and plunger pump can also be used as metering pump
