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.

SMS: Spunbond non-woven fabric + meltblown non-woven fabric + spunbonded non-woven fabric = three-layer fiber web hot-rolled, which is a composite non-woven fabric. The non-woven equipment uses a double-bearing enclosed bushing with high precision , The fiber can be fully carded, and the cotton web will be evenly added. Non-woven equipment is mainly a kind of mechanical equipment that uses non-woven fabrics, melt-blown fabrics, etc. as raw materials, and uses the pressure-cutting function of ultrasonic waves to produce filter cotton of various shapes and sizes. It produces spunbonded and melt-blown composite products. , Has the advantages of high strength, good filtering performance, no adhesive, non-toxic and so on. It is non-toxic, tasteless, and highly effective in separating bacteria. Through the special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water repellent and water production properties. Mainly used in medical and health labor protection products such as surgical gowns, surgical caps, protective clothing, hand washing clothes, handbags, etc. The thin SMS non-woven fabric (10-25gsm), due to its waterproof and breathable properties, is especially suitable for the sanitary market, such as sanitary napkins, sanitary pads, baby diapers, adult incontinence diapers, side leakage prevention and backing, etc. Medium-thickness SMS non-woven fabric (25-50gsm), suitable for use in medical treatment, making surgical gowns, surgical wraps, surgical drapes, sterilization bandages, wound placards, plasters, etc. It is also suitable for industrial use. Make work clothes, protective clothing, etc. SMS products are more suitable for high-quality medical protective materials due to their good isolation performance, especially those SMS products that have undergone three anti-static and anti-static treatments, and have been widely used worldwide. Thick SMS products (>55gsm) are widely used as high-efficiency filter materials for various gases and liquids. At the same time, they are also excellent high-efficiency oil-absorbing materials. They are used in industrial waste water degreasing, marine oil cleaning and industrial wipes.
