德国KAYSEN凯森进口高压柱塞泵概述
高压柱塞泵的使用压力一般应在10MPa~100MPa之间。它属于容积式泵,借助工作腔里的容积周期性变化来达到输送液体的目的;原动机的机械能经泵直接转化为输送液体的压力能;泵的容量只取决于工作腔容积变化值及其在单位时间内的变化次数,理论上与排出压力无关。往复泵是借助于活塞在液缸工作腔内的往复运动(或通过隔膜、波纹管等挠性元件在工作腔内的周期性弹性变形)来使工作腔容积产生周期性变化的。在结构上,往复泵的工作腔是借助密封装置与外界隔开,通过泵阀(吸入阀和排出阀)与管路沟通或闭合。

主要特点:

瞬时流量是脉动的

这是因为在柱塞泵中,液体介质的吸入和排出过程是交替进行的,而且活塞在位移过程中,其速度又在不断地变化之中。在只有一个工作腔的泵中,泵的瞬时流量不仅随时间而变化,而且是不连续的。随着工作腔的增多,瞬时流量的脉动幅度越来越小,乃至在实用上可以认为是紊流。

平均流量是恒定的

理论上,泵的流量只取决于泵的主要结构参数 n(每分钟往复次数)、S(活塞行程)、D(活塞直径)、Z(活塞数目),与排出压力无关,且与输送介质的温度、粘度等物理、化学性质无关。所以说泵的流量是恒定的。

泵的压力取决于管道特性

柱塞泵的排出压力不能由泵本身限定,而是取决于泵装置的管道特性,并且与流量无关。也就是说,如果认为输送液体是不可压缩的,那么,在理论上可认为往复泵的排出压力将不受任何限制,即可根据泵装置的管道特性,建立泵的任何所需的排出压力。当然,所有往复泵都有一个泵的排出压力的规定,这不是说该泵的排出压力不会再升高,而只是说,由于原动机额定功率和泵本身的结构强度的限制,不允许在超出这一排出压力下使用而己。

对输送介质有较强的适应性

柱塞泵原则上可以输送任何介质,几乎不受介质的物理性能和化学性能的限制。当然,由于液力端的材料和制造工艺以及密封技术的限制,有时也会遇到不能适应的情况。

有良好的自吸性能

柱塞泵不仅有良好的吸入性能,而且还有良好的自吸性能。因此,对多数往复泵来说,在启动前通常不需灌泵。 机器效率高,节能。

Germany KAYSEN imported high pressure piston pump overview
The pressure of the high-pressure piston pump should generally be between 10MPa and 100MPa. It belongs to the positive displacement pump, with the working chamber in the volume of cyclical changes to achieve the purpose of transporting the liquid; the original machine mechanical energy pump directly into the transmission of liquid pressure energy; pump capacity depends only on the working chamber volume changes and its The number of changes in unit time is theoretically independent of discharge pressure. The reciprocating pump causes the working chamber volume to periodically change by means of the reciprocating motion of the piston in the cylinder operating chamber (or by periodic elastic deformation of the flexible element such as a diaphragm, bellows or the like in the working chamber). In the structure, the reciprocating pump working chamber is separated from the outside by means of a sealing device, through the valve (suction valve and discharge valve) to communicate with the pipeline or closed.

main feature: 

● Instantaneous flow is pulsating
This is because in the plunger pump, the liquid medium inhalation and discharge process is alternating, and the piston in the displacement process, the speed is constantly changing. In a pump with only one working chamber, the instantaneous flow of the pump varies not only with time but also in a discontinuous manner. With the increase in the working chamber, the instantaneous flow rate of the pulse is getting smaller and smaller, and even in practice can be considered turbulent.
● The average flow rate is constant
In theory, the flow of the pump depends only on the main structural parameters n (reciprocating times per minute), S (piston stroke), D (piston diameter), Z (number of pistons), regardless of discharge pressure, Temperature, viscosity and other physical and chemical properties have nothing to do. So the flow of the pump is constant.
● The pressure of the pump depends on the pipe characteristics
The discharge pressure of the plunger pump can not be limited by the pump itself, but depends on the piping characteristics of the pump device and is independent of the flow rate. That is, if it is considered that the delivery liquid is incompressible, it is theoretically believed that the discharge pressure of the reciprocating pump will be free from any restriction and any desired discharge pressure of the pump may be established in accordance with the pipe characteristics of the pump unit. Of course, all reciprocating pumps have a pump discharge pressure requirement, which is not to say that the pump's discharge pressure will not rise again, but only that, due to the prime mover rated power and the structural strength of the pump itself is not allowed Beyond the use of this discharge pressure.
● Strong adaptability to the conveying medium
Piston pumps can in principle deliver any medium, almost free of physical and chemical properties of the media. Of course, due to the hydraulic end of the material and manufacturing process and sealing technology constraints, and sometimes can not meet the situation.
● have good self-priming performance
Piston pump not only has good inhalation performance, but also good self-priming performance. Therefore, for most reciprocating pumps, there is usually no need to pump before starting. Machine efficiency is high, energy saving.

Key Benefits:

● High efficiency
● High pressure
● long life

● Wide speed range
● have good self-priming performance
