GERMANY KAYSEN PUMP CO .,LTD
The working pressure of the high pressure piston pump should generally be between 10 MPa and 100 MPa. It belongs to a positive displacement pump, and the purpose of conveying liquid is achieved by the periodic change of the volume in the working chamber; the mechanical energy of the prime mover is directly converted into the pressure energy of the liquid by the pump; the capacity of the pump depends only on the volume change of the working chamber and The number of changes in unit time is theoretically independent of the discharge pressure. The reciprocating pump periodically changes the working chamber volume by means of the reciprocating motion of the piston in the working chamber of the liquid cylinder (or periodic elastic deformation in the working chamber by flexible elements such as diaphragms and bellows). Structurally, the working chamber of the reciprocating pump is separated from the outside by means of a sealing device, and communicates or closes with the pipeline through the pump valve (suction valve and discharge valve).
● Instantaneous flow is pulsating
This is because in the plunger pump, the suction and discharge processes of the liquid medium alternate, and the speed of the piston is constantly changing during the displacement process. In a pump with only one working chamber, the instantaneous flow of the pump not only changes over time, but is also discontinuous. As the working chamber increases, the amplitude of the pulsation of the instantaneous flow becomes smaller and smaller, and even practically, it can be considered as turbulent flow.
●The average flow is constant
In theory, the pump flow depends only on the pump's main structural parameters n (reciprocation times per minute), S (piston stroke), D (piston diameter), Z (number of pistons), independent of discharge pressure, and with the transport medium. Physical and chemical properties such as temperature and viscosity are irrelevant. So the pump flow is constant.
●The pressure of the pump depends on the characteristics of the pipe
The discharge pressure of the plunger pump cannot be defined by the pump itself, but depends on the piping characteristics of the pump unit and is independent of the flow rate. That is to say, if the delivery liquid is considered to be incompressible, then it is theoretically considered that the discharge pressure of the reciprocating pump will not be unduly limited, and any desired discharge pressure of the pump can be established depending on the piping characteristics of the pump device. Of course, all reciprocating pumps have a discharge pressure regulation of the pump. This is not to say that the discharge pressure of the pump will not rise any more, but only because of the limitation of the prime mover's rated power and the structural strength of the pump itself, it is not allowed. Use it beyond this discharge pressure.
● Strong adaptability to the transport medium
In principle, the plunger pump can transport any medium, virtually independent of the physical and chemical properties of the medium. Of course, due to the limitations of the material and manufacturing process of the hydraulic end and the sealing technology, sometimes it is difficult to adapt.
●Good self-priming performance
The plunger pump not only has good suction performance, but also has good self-priming properties. Therefore, for most reciprocating pumps, there is usually no need to prime the pump before starting. The machine is efficient and energy efficient.
The main advantage:
●High pressure resistance
●High transmission power
● Wide speed range
●Good self-priming performance
●Mine metallurgical machinery
●Petroleum Fine Chemicals
●Food and drug processing
