Reciprocating pump application features explain

Posted by uuuseff on November 18th, 2019

What are the characteristics of reciprocating pump application? ① high efficiency and wide area. ② to achieve high pressure, pressure changes almost does not affect the flow, which can provide a constant flow. ③ self-priming capability, can transport liquid, gas mixture, specially designed can also transport mud, concrete and so on. ④ flow and pressure pulsation, especially single-acting pump, due to the acceleration of piston movement and liquid discharge intermittent, greater pulsation. It is usually necessary to set the air chamber on the discharge line (and sometimes on the suction line) to make the flow more uniform. The use of double-acting and multi-cylinder pumps also significantly improves flow nonuniformity. ⑤ low speed, large size, the structure is more complex than the centrifugal pump, the need for a special valve, manufacturing costs and installation costs are higher. Piston pump is mainly used for water supply, manual piston pump is a widely used household life pump. Piston pumps are used to provide high-pressure liquid sources, such as high-pressure water supply hydraulic machine, piston pump and it can be used as oil drilling mud pump, pump. Diaphragm pumps are particularly suitable for the delivery of highly toxic, radioactive, corrosive liquids, valuable liquids and fluids containing rubble solids. Diaphragm pumps and piston pumps can also be used as metering pumps.
