Self-priming pump is commonly used in the South a pump. The principle is the use of water flow momentum, impeller driven pump impeller to the river above the water. The pump can be pumped into the river to pump water, but it must be in immediate rush or fall.
Self-priming pumps and centrifugal pumps in general different.
Centrifugal pump] Pump before work, the pump body and the inlet pipe must be full of water into a vacuum state, when the impeller is rapidly rotating, the leaves to promote rapid rotation of water, rotating water in the centrifugal force from the impeller to fly, After the water inside the pump is thrown out, the central part of the impeller forms a vacuum area. Suwon's water pressure in the air pressure (or water pressure) under pressure through the pipe into the water pipe. This endless cycle, you can achieve continuous pumping.
Self-priming pump is not required for irrigation, which is the origin of self-priming pump.
Self-suction self-absorption principle: Due to the special design of the pump shell. The sealing performance than the average centrifugal pump high, and the pump out of the water after the motor is out of service will not automatically empty, the motor driven turbine high-speed rotation, the rapid formation of negative pressure pump (vacuum). The use of atmospheric pressure to the pump shell, and then centrifugal lift. So self-priming pump suction will not exceed one atmosphere, about 11M.
1, Suitable for urban environmental protection, construction, fire fighting, chemical, pharmaceutical, dye, printing and dyeing, brewing, electric power, electroplating, paper making, mining and washing, equipment cooling.
2, fitted with rocker-type nozzle, but also the water rushed into the air, scattered into a small raindrop spray, farm, nursery, orchards, vegetable gardens, a good tool.
3, for water, sea water and with acid, alkalinity of the chemical medium liquid and paste with a general paste (medium viscosity <100 PCT, solids content of up to 30% 4, and any type, Specifications supporting the use of filter press, the slurry sent to the filter press for the best supporting pump pressure pump.

The main raw materials of cordierite ceramics are talc, clay, alumina, feldspar and the like. Made using a general ceramic process. The sintering range is narrow, and the sintering temperature differs only a few degrees from the decomposition temperature of cordierite, making it difficult to obtain a dense body. As an additive, chlorite, magnesium carbonate, cesium carbonate, zirconium silicate, zirconium dioxide, boron trioxide, spodumene, etc. are generally used as additives to lower the sintering temperature, expand the firing temperature range, and improve the dielectric. performance. It can be used as a coil former, an arc-resistant electrical insulating material, a base material of a composite material, a material of a burner nozzle of an electric heating insulating device, and the like.
