Background technique
Reciprocating pump relies on the to-and-fro motion in pumping cylinder of piston, plunger or barrier film to make swept volume in cylinder alternately increase and reduce the positive displacement pump carried liquid or make it supercharging.Reciprocating pump is divided into reciprocating pump, plunger pump and diaphragm pump 3 type by reciprocal element difference.When piston moves from left to right, form negative pressure in pumping cylinder, then in storage tank, liquid enters in pumping cylinder through suction valve.When piston right-to-left moves, in cylinder, liquid is squeezed, pressure] increase, discharged by expulsion valve.Once, each suction and a discharge liquid, be called a work cycle to piston reciprocating; This pump is called single acting pump.If piston round trip, each suction and discharge twice liquid, be called double action pump.Piston moves to the other end by one end, is called a stroke.
The flow of reciprocating pump and pressure head have nothing to do, relevant with pumping cylinder size, stroke of piston and reciprocal time.The theoretical delivery of single acting pump is that the actual flow of QT=Asn reciprocating pump is less than theoretical delivery, and reduces along with increasing of pressure head, this is because caused by leakage.The flow of reciprocal pump head and pump and the physical dimension of pump have nothing to do, and are determined by factors such as the mechanical strength of pump, the power of prime mover.
Reciprocating pump does not need to pour into liquid when starting, and because reciprocating pump has suction capacity, but its suction vacuum also changes with the atmospheric pressure of pump operating area, the character of liquid and temperature, therefore the setting height(from bottom) of reciprocating pump also has a definite limitation.The flow of reciprocating pump can not regulate with the valve on discharge conduit, and by-pass pipe should be adopted or change piston reciprocal time, change the stroke of piston and realize.Reciprocating pump must by the valve open in discharge conduit before starting.The piston of reciprocating pump is connected with prime mover by connecting bar and crankshaft.Prime mover can electricity consumption] machine, also used vapour machine.Reciprocating pump is applicable to the conveying of high-head, small flow, high viscosity liquid, but is unsuitable for conveying corrosive liquid.Sometimes directly driven by steamer, carry inflammable, explosive liquid.Current existing reciprocating pump structure is complicated, and install inconvenient, operation stability is not high, and using scope is less.
