現(xiàn)以活塞式為例來說明往復(fù)泵工作原理。
Now to an example to illustrate the reciprocating piston pump works.
活塞泵主要由活塞在泵缸內(nèi)作往復(fù)運動來吸入和排除液體。
Piston pump mainly by the piston in the pump cylinder for reciprocating motion to breathe and remove the liquid.
當活塞開始自極左端位置向右移動時,工作室的容積逐漸擴大,室內(nèi)壓力降低,流體頂開吸水閥,進入活塞所讓出的空間,直到活塞移動到極右端為此,此過程為泵的吸水過程。
When the piston began to move from the extreme left side position to the right, the studio gradually expanded volume, an indoor pressure has eased, fluid top-opening suction valve and piston are let out into space, until the piston to move to ultra-right-side end, this process is pump The water absorption process.
當活塞從右端開始向左端移動時,充滿泵的流體受擠壓,將吸水閥關(guān)閉,并打開壓水閥而排出,此過程稱為泵的壓水過程。
When the piston to the left side starting from the right end of the move, filled with fluid by squeezing the pump, the suction valve closed, and open the pressure valve and the discharge, this process is known as the process of pressurized water pump.
活塞不斷往復(fù)運動,泵的吸水與壓水過程就連續(xù)不斷地交替進行。此泵特點是:泵壓力可以無限高,流量與壓力無關(guān),具有自吸能力,流量不均勻。此泵適用于小流量、高壓力的輸液系統(tǒng)。
Continuously reciprocating piston movement, the pump suction and the pressurized water process is continuous alternately. This pump features are: unlimited high pump pressure, flow and pressure has nothing to do with self-priming capability, flow unevenly. This pump is suitable for small flow, high pressure infusion system. |
