Circulating water with vacuum pump works: circulating water pump with a suitable amount of water as the working fluid pump. When the impeller rotates clockwise 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 lower part of the water loop of the circulating water pump is just tangential to the impeller hub. The upper inner surface of the water ring is exactly opposite to the tip of the vane (in fact, the vane has a fixed insertion depth in the water ring). At this moment, a crescent space is formed between the impeller hub and the water ring, and the space is divided into a plurality of small cavities equal to the number of the blades by the impeller. If the lower part of the impeller as a starting point, then the impeller 180 degrees before rotation, the small cavity area from small to large, and with the suction port on the end of the interface, when the gas is inhaled, when the inhalation of small cavity And the suction port isolated; when the impeller continues to rotate, the small cavity from large to small, so that the gas is compressed; when the small chamber communicates with the exhaust port, the gas will be discharged outside the pump. SHZ-CA anti-corrosion shell three-tap water cycle vacuum pump is a new high-power multi-head pump anticorrosive shell circulating water with a vacuum pump, the design of internal and external circulation of water, five simultaneous extraction, with no oil, no pollution, Power, low noise, convenient and flexible, saving water and electricity, etc., a multi-purpose machine. (1) SHZ-CA anti-corrosion shell three-tap water circulation with a vacuum pump a single multi-tube operation, with five suction head, can be used alone or in parallel. (2) SHZ-CA anti-corrosion shell three-tap water cycle more vacuum pump corrosion-resistant, pollution-free, stable operation, low noise, long life. (3) SHZ-CA anti-corrosion shell three-tap water cycle with a vacuum pump host polypropylene and stainless steel two models. SHZ-CA anti-corrosion shell three-tap water circulation vacuum pump Technical parameters:
