进口水环真空泵/Vacuum pump/德国品质
德国KAYSEN凯森进口水环真空泵概述
水环真空泵内装有带固定叶片的偏心转子，将水（液体）抛向定子壁，水（液体）形成与定子同心的液环，液环与转子叶片一起构成可变容积的一种旋转变容积真空泵。水环真空泵适用于抽除气体和水蒸气，吸气压力可以达到33mbar绝压(97%真空度)。当用变压器油作为工作液时（称为油环真空泵），吸气压力可达到6.7mbar绝压(99.3%真空度），可以完全取代往复式真空泵。
主要特点：
水环真空泵（简称水环泵）是一种粗真空泵，它所能获得的极限真空为2000~4000Pa，与真空泵组成机组真空度可达1~600Pa。水环泵也可用作压缩机，称为水环式压缩机，是属于低压的压缩机，其压力范围为1~2×105Pa表压力。由于真空应用技术的飞跃发展，水环泵在粗真空获得方面一直被人们所重视。由于水环泵中气体压缩是等温的，故可抽除***、***的气体，此外还可抽除含尘、含水的气体，因此，水环泵应用日益增多。
在泵体中装有适量的水作为工作液。当叶轮按图中指示的方向顺时针旋转时，水被叶轮抛向四周，由于离心力的作用，水形成了一个决定于泵腔形状的近似于等厚度的封闭圆环。水环的上部分内表面恰好与叶轮轮毂相切，水环的下部内表面刚好与叶片顶端接触（实际上叶片在水环内有一定的插入深度）。此时叶轮轮毂与水环之间形成一个月牙形空间，而这一空间又被叶轮分成叶片数目相等的若干个小腔。如果以叶轮的上部0°为起点，那么叶轮在旋转前180°时小腔的容积由小变大，且与端面上的吸气口相通，此时气体被吸入，当吸气终了时小腔则与吸气口隔绝；当叶轮继续旋转时，小腔由大变小，使气体被压缩；当小腔与排气口相通时，气体便被排出泵外。
综上所述，水环泵是靠泵腔容积的变化来实现吸气、压缩和排气的，因此它属于变容式真空泵。

Germany KAYSEN imported water ring vacuum pump overview
The water ring vacuum pump is equipped with an eccentric rotor with fixed blades to throw water (liquid) to the stator wall. The water (liquid) forms a liquid ring concentric with the stator, and the liquid ring and the rotor blade together form a variable volume of the variable volume. Vacuum pump. The water ring vacuum pump is suitable for pumping out gas and water vapor, and the suction pressure can reach 33 mbar absolute pressure (97% vacuum). When using transformer oil as the working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7 mbar absolute pressure (99.3% vacuum), which can completely replace the reciprocating vacuum pump.
main feature:
Water ring vacuum pump (referred to as water ring pump) is a kind of rough vacuum pump, which can obtain the ultimate vacuum of 2000~4000Pa, and the vacuum unit with vacuum pump can reach 1~600Pa. The water ring pump can also be used as a compressor, called a water ring compressor, which is a low pressure compressor with a pressure range of 1 to 2 x 105 Pa gauge. Due to the rapid development of vacuum application technology, water ring pumps h***e been paid attention to in the acquisition of rough vacuum. Since the gas compression in the water ring pump is isothermal, the flammable and explosive gas can be removed, and the dusty and water-containing gas can be removed. Therefore, the application of the water ring pump is increasing.
An appropriate amount of water is contained in the pump body as a working fluid. When the impeller rotates clockwise in the direction indicated in the figure, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness depending on the shape of the pump chamber. The inner surface of the upper portion of the water ring is just tangent to the impeller hub, and the lower inner surface of the water ring is just in contact with the tip of the blade (actually the blade has a certain depth of insertion within the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided by the impeller into a plurality of ***all c***ities h***ing the same number of blades. If the upper part of the impeller is 0°, the volume of the ***all c***ity becomes ***aller from 180° before the rotation, and it communicates with the suction port on the end face. At this time, the gas is sucked in, and when the inhalation is finished, the c***ity is ***all. It is isolated from the suction port; when the impeller continues to rotate, the ***all c***ity becomes larger and ***aller, so that the gas is compressed; when the ***all c***ity communicates with the exhaust port, the gas is discharged outside the pump.
In summary, the water ring pump relies on the change of the volume of the pump chamber to achieve the suction, compression and exhaust, so it belongs to the variable displacement vacuum pump.
