High pressure reciprocating pump is composed of electric motor, coupling, reducer, transmission part, pump head part, common base and so on.
High pressure reciprocating pump advantages
(1) can get a high pressure, and the flow and pressure has nothing to do, inhalation performance is good, high efficiency, which steam reciprocating pump up to 80% to 95%;
(2) In principle, any medium can be conveyed, High-pressure Reciprocating Pump almost free of physical or chemical properties of the media;
(3) The performance of the pump does not vary with pressure and the viscosity of the conveying medium.
High pressure reciprocating pump construction: Main components: pump cylinder, piston, discharge valve, piston rod and suction valve.
High-pressure reciprocating pump works:
When the piston moves from left to right, the pump cylinder to form a negative pressure, the import pipeline of liquid through the suction valve into the pump cylinder. High-pressure Reciprocating Pump When the piston moves from right to left, the cylinder liquid is squeezed, the pressure increases, there are discharge valve discharge. Pistons reciprocating once, the inhalation and discharge of a liquid, known as a working cycle; High-pressure Reciprocating Pump this pump is called a single pump. If the piston from time to time, the inhalation and discharge of two liquids, known as double-action pump. The piston moves from one end to the other, called a stroke.
Installation height and flow regulation of high pressure reciprocating pump
High pressure reciprocating pump is not required to start filling the liquid, because the high pressure reciprocating pump has the self-absorption ability, but its suction vacuum height also with the installation area of the atmospheric pressure, the nature and temperature of the liquid changes, High-pressure Reciprocating Pump so the high pressure reciprocating pump installation height also Must be limited. High-pressure reciprocating pump flow can not be used to discharge the valve on the pipeline to adjust, but should be used to bypass the pump or change the number of reciprocating piston to change the piston stroke to achieve. The high-pressure reciprocating pump must be opened before the valve in the discharge line.
The piston of the high-pressure reciprocating pump is connected to the prime mover by the connecting curve. The main engine can be used motor, can also be used diesel engine, high pressure reciprocating pump for high pressure head, small flow, low viscosity liquid delivery, but not for the transport of corrosive liquids, High-pressure Reciprocating Pump and sometimes driven by the steam engine directly, transport flammable, explosive liquid.
High pressure reciprocating pump flow and indenter
The flow rate of the high-pressure reciprocating pump is independent of the indenter and is related to the size of the cylinder, the number of reciprocating pistons. The theoretical flow of the single-flow pump is QT = Asn The actual flow rate of the reciprocating pump is smaller than the theoretical flow and decreases with the increase of the indenter, which is due to the leakage. The pressure of the high pressure reciprocating pump is independent of the flow rate of the pump and the geometry of the pump, and is determined by factors such as the mechanical strength of the pump and the power of the prime mover.
