The vacuuming principle of circulating water-type multi-vacuum pumps is a centrifulation mechanical pump.
eccentricity device is installed in the cylinder-shaped pump shell, and when the impeller rotates, water forms a water ring under the force of centrifution.
due to the eccentric position of the impeler, the water ring is relative to the blade, so that the spatial volume between the adjacent two blades changes periodically, as in the liquid "piston" leaf gate for radial back-and-forth operation.
the impelation rotates steadily, each volume wheel changes repeatedly, so that the suction and exhaust process continues.
can be automatically started and stopped at any time according to the vacuum degree of the system.
when the system vacuum is reduced, the unit is equipped with three circulating water vacuum pumps. Invest one or two units during normal operation.
ensure that the pumping pressure operates within the specified range.
Circulating water multi-use vacuum pump use method: 1, circulating water-type multi-vacuum pump first open the water tank on top of the cover, from the middle of the closed layer of water added to clean tap water, the water level rose to a particularly good scale.
2, circulating water-type multi-vacuum pump to plug in the power supply, the random belt of the power cord and the body's connecting end plug on the body side of the socket, so that it firmly match and then the other end of the power cord firmly plugged into the power outlet.
3, circulating water-type multi-vacuum pump vacuum operation, will pump the vacuum equipment pumping sleeve tightly connected to the pumping nozzle on the side of the body;
4, recycled water multi-vacuum pump to provide circulating cooling water, in the reaction device to provide circulating water cooling water, the casing on the other side of the machine on the circulating water nozzle, and then make the other end of the sleeve in the need for circulating cooling water reaction mount, start the circulating water out switch can achieve the supply of circulating cooling water.
5, circulating water-type multi-vacuum pump natural external circulation when the native to work for a long time, in order to prevent the rise of circulating water temperature and shadow vacuum effect.
Circulating water vacuum pump can put the water hose and tap water on, water nozzle with a hose connected into the water to control the flow of tap water, so that it forms a state of natural external circulation, continuous supplementary replacement of clean tap water, in order to maintain the circulating water temperature will not be too high, then do not affect the vacuum effect.
