KS.High pressure piston pump

德國KAYSEN凱森進口高壓柱塞泵

Overview of High Pressure Piston Pumps
高壓柱塞泵的使用壓力一般應在10MPa～100MPa之間。它屬于容積式泵，借助工作腔里的容積周期性變化來達到輸送液體的目的；原動機的機械能經(jīng)泵直接轉(zhuǎn)化為輸送液體的壓力能；泵的容量只取決于工作腔容積變化值及其在單位時間內(nèi)的變化次數(shù)，理論上與排出壓力無關(guān)。往復泵是借助于活塞在液缸工作腔內(nèi)的往復運動（或通過隔膜、波紋管等撓性元件在工作腔內(nèi)的周期性彈性變形）來使工作腔容積產(chǎn)生周期性變化的。在結(jié)構(gòu)上，往復泵的工作腔是借助密封裝置與外界隔開，通過泵閥（吸入閥和排出閥）與管路溝通或閉合。

主要特點：KS.Features

●瞬時流量是脈動的

這是因為在柱塞泵中，液體介質(zhì)的吸入和排出過程是交替進行的，而且活塞在位移過程中，其速度又在不斷地變化之中。在只有一個工作腔的泵中，泵的瞬時流量不僅隨時間而變化，而且是不連續(xù)的。隨著工作腔的增多，瞬時流量的脈動幅度越來越小，乃至在實用上可以認為是紊流。

●平均流量是恒定的

理論上，泵的流量只取決于泵的主要結(jié)構(gòu)參數(shù)　n（每分鐘往復次數(shù)）、S（活塞行程）、D（活塞直徑）、Z（活塞數(shù)目），與排出壓力無關(guān)，且與輸送介質(zhì)的溫度、粘度等物理、化學性質(zhì)無關(guān)。所以說泵的流量是恒定的。

●泵的壓力取決于管道特性

柱塞泵的排出壓力不能由泵本身限定，而是取決于泵裝置的管道特性，并且與流量無關(guān)。也就是說，如果認為輸送液體是不可壓縮的，那么，在理論上可認為往復泵的排出壓力將不受任何限制，即可根據(jù)泵裝置的管道特性，建立泵的任何所需的排出壓力。當然，所有往復泵都有一個泵的排出壓力的規(guī)定，這不是說該泵的排出壓力不會再升高，而只是說，由于原動機額定功率和泵本身的結(jié)構(gòu)強度的限制，不允許在超出這一排出壓力下使用而己。

●對輸送介質(zhì)有較強的適應性

柱塞泵原則上可以輸送任何介質(zhì)，幾乎不受介質(zhì)的物理性能和化學性能的限制。當然，由于液力端的材料和制造工藝以及密封技術(shù)的限制，有時也會遇到不能適應的情況。

●有良好的自吸性能

柱塞泵不僅有良好的吸入性能，而且還有良好的自吸性能。因此，對多數(shù)往復泵來說，在啟動前通常不需灌泵。機器效率高，節(jié)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.
