Water ring vacuum pump is a kind of water as the working medium, by rotating the eccentric, the water by centrifugal force, and in the wall to form a spin pump water ring, turn the course of the first half, with a round face and gradually departing from the water ring suction system, between the impeller blades and the water ring to form a closed space, with the rotation of the impeller, the space being gradually expanded, the space pressure is gradually decreased, the gas is sucked into the space, after a half turn in the process, the inner surface of the water ring gradually and close to the wheel, the space between the blades is gradually reduced, the space pressure rises, when exhaust port pressure is higher than the gas between the blades is discharged. So continuous suction or pressure feed gas. Thereby creating a vacuum suction pipe loop, water ring vacuum pump is the ideal choice for hospital suction system. Two water ring vacuum pump start and stop the use of automatic and manual control. In automatic control state, when the system vacuum is below the set limit, the automatic control cabinet will sound and light alarm simultaneously start a unit, if a machine within a certain period of time (adjustable) not reached within a predetermined When the vacuum value, the second unit to automatically start; vacuum until the system reaches the set limit, the automatic control cabinet will sound and light alarm simultaneously two pump automatically stops running.
