Working principle of self-suction pump
Self-suction pump is a commonly used pump. The principle is the use of the water flow momentum, driven impeller
pump impeller to pump the water to the bank above. This pump can be pumped in the river, but it must be urgent,
or there is a gap between the two places.
Self-suction pump and general centrifugal pump are different. Before the operation, centrifugal pump and inlet
pipe must be full of water tank into a vacuum line, when the fast rotating impeller and blade to promote water
quickly rotation, rotating water under the action of centrifugal force flew from the impeller, pump the water
is thrown, the central part of the impeller shape space come true. The water in air pressure (or pressure) th-
rough the pipe network under the inlet pressure to the inside. Such a cycle, you can achieve continuous pumping.
Since the suction pump is not required to fill the diversion, which is the origin of the suction pump.
Self-suction principle of self-suction pump:
because of the special design of the pump shell, the sealing performance of the centrifugal pump is higher than
the ordinary centrifugal pump, and the pump shell after the motor is not automatically drained, the motor drives
the turbine to rotate quickly, so that the pump can form a negative pressure (vacuum). Use of the pressure to
the pump shell, after the centrifugal lift. Therefore, the suction pump suction process will not exceed an atmo-
spheric pressure, 11M or so.
Application range of self-suction pump
1. Suitable for urban environmental protection, construction, fire, chemical, pharmaceutical, dyes, printing and
dyeing, brewing, power, electroplating, paper, mining flushing, equipment cooling, etc.
2. Mounted on the rocker type nozzle, and can be water into the air, scattered into fine raindrops spray, is the
farm, nursery, orchard, vegetable garden of good machine.
3. Suitable for water, seawater and with acid and alkali chemical liquid medium and with generally pasty slurry
(medium viscosity < 100 centipoise, containing solid volume reaches 30% below).
4. Any type and specification of filter press machine supporting the use, the slurry to give press filter for
filter press is the most ideal supportive pump type.
