Nanguang vacuum

Water ring vacuum pump (hereinafter referred to as water ring pumps) is a kind of coarse vacuum pump, it can get the limit of the vacuum for 2000-4000 mpa, series air spray can reach 270 mpa. Water ring pump also used for compressor, called water ring type compressor, it is to belong to a low-pressure compressor, the pressure range for 1 to 2 X105 palmer table pressure.

Water ring vacuum pumps first self-priming pumps, and then used as gradually used in oil, chemical industry, machinery, mining, light industry, medicine and food and many other industrial department. In the industrial production of many of the process, such as vacuum filter, vacuum water diversion and vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture and the vacuum takes off gas, water ring pump widely used. Because of the rapid development of the vacuum application technology, water ring vacuum pumps in thick get has been taken seriously by people place. Because water pump gas compression ring of isothermal, and it is can smoke except inflammable, explosive gas, in addition, it also can smoke except the dusty, water cut gas, therefore, water ring pump application are increasing.

Pump body with right amount water in as a working fluid. When impeller according to the figure clockwise, water was thrown around, because impeller centrifugal force, the role of the water forms a decision in the shape of the pump chamber is similar to the thickness of the closed ring, etc. The lower part of the water ring their fair share of the surface coincided with the impeller hub, water ring on the tangent cottrell and blade surface was the top (actually leaves in the water in the ring for insertion depth). At this time the impeller with water ring wheel hub formed between a crescent space, and this one space and be impeller and blade number equal divided into several small chamber. If the lower part of the impeller to zero as the starting point, and then in rotating impeller before 180 degrees, small cavity area turned from small to big, and end on the mouth and breathe in interlinked, at this time, when the air is inhaled breathe in the end is small and isolated from the mouth cavity in; When impeller continues to rotate, the chamber by bigger or smaller, make the air is compressed; When small cavities and vent interlinked, gas and expelled the pump.

To sum up, water ring pump is the change of the volume on pump chamber to achieve the suction, exhaust, compression and therefore it belongs to the transfiguration vacuum pump.

ROM. Watts of pump working principle:

ROM. Watts pump chamber, have two "8" glyph rotor mutual vertically installed in a parallel axis, the transmission ratio of 1 for a pair of gear drive each other synchronous rotation movement reverse. In between rotor and pump rotor, shell, keep a wall between the gap, can achieve high speed operation. Because ROM watts series pump use.

ROM. Watts pump working principles and ROM watts similar blower. Because of the rotor constantly spins are pumping gas from the inlet inhaled to rotor and pump shell inside the space between, then after vent discharge. Because of the space to breathe in the VO think is fully enclosed state, so in gas inside the pump chamber, no compression and expansion.
