Self suction pump is a commonly used pump in the south. 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 into the river, but it must be in a hurry, or there is a gap.
Self priming pump and general centrifugal pump.
Centrifugal pump before work, the pump body and the water pipe must be filled with water into a vacuum state, when the impeller is quick to rotate, the water is very fast rotating, rotating the water under the action of centrifugal force from the impeller, the water is thrown out, the center of the impeller to form a vacuum region. The water in air pressure (or pressure) through the pipe network under the inlet pressure to the inside. Such a cycle, you can achieve continuous pumping.
Self suction pump is not required to fill the water, which is the origin of the self suction pump.
The principle of self absorption: because of the special design of the pump casing. The sealing performance of the centrifugal pump is higher than the general, and the motor is not automatically drained after the pump shell, the motor drives the turbine to rotate quickly, so that the formation of negative pressure (vacuum). The pressure will be used to pump the shell with the pressure, and then the centrifugal head. So the suction pump suction process will not exceed a large pressure, 11M or so.
1, suitable for urban environmental protection, construction, fire, chemical, pharmaceutical, dyes, printing and dyeing, brewing, electric power, electroplating, paper, industrial washing, equipment cooling, etc..
2, mounted on the rocker type nozzle, and the water will be washed into the air, scattered into small raindrops on the spray, is the farm, nursery, orchard, vegetable garden of good equipment.
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% the following
4, and 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 kind.
