Sewage pump is a non-clogging pump, with many forms: such as submersible and dry two, the most common submersible WQ submersible sewage pump, the most common dry sewage pump, such as W-type horizontal Sewage pump and WL vertical sewage pump two. Mainly used to transport urban sewage, manure or liquid containing fiber. Paper and other solid particles of media, the medium is usually the temperature is not more than 80 ℃.
Due to the media being conveyed contain easily entangled or bunched fibers. Therefore, the kind of pump flow channel is easy to block, once the pump is blocked, the pump can not work normally, or even burn the motor, resulting in poor drainage. To urban life and environmental protection have a serious impact. Therefore, the anti-clogging and reliability of the sewage pump is an important factor in the pros and cons.
Sewage pump is an application named, in fact, rubber lining slurry pump as a horizontal sewage pump application is very good. In the treatment of industrial sewage, because the sewage contains acidic or alkaline substances, lined rubber pump is widely used. According to some application cases of the pump, the rubber lined rubber pump and metal impeller can both achieve the high pressure and high efficiency of the metal pump and can fully exert the corrosion resistance of the rubber material. In the treatment of urban sewage, the sewage treatment pond will normally be preceded by a filter to prevent the stowing of fibers from entering the pump inlet so that the pump can work better and have a longer life. long.
Sewage pump parameters: Pump performance parameters polarization
(1) The flow range: generally Q = 0.2 ~ 10000m3 / h, now there is a trend towards polarization. The maximum flow rate of submersible sewage pump produced by Sweden ABS pump is Q = 25000m3 / h, while Bomba, Spain. Elias company's submersible sewage pump minimum flow Q = 0.02m3 / h.
(2) Head: generally h = 10 ~ 100m, the development of the two poles is particularly obvious, the United States sent Branch pump submersible sewage pump lift the highest value h = 150m, while the United States disco Plow the highest sewage pump can reach h = 400m. Japan's EIM Motor Co., Ltd. submersible sewage pump head lift h = 1m.
(3) Motor power: submersible sewage pump motor power, usually 1 ~ 600kW, Spain Bomba. Elias company minimum power of 0.08kW, while the Swiss ABS pump company's motor maximum power 900kW.
(4) The maximum size of solids passing through: The submersible sewage pump allows the maximum particle size of solid matter to pass through, generally d = 50-150mm. The submersible sewage pump manufactured by Ferulva Pump Company of Germany allows the maximum particle size d = 35mm, Disco Fowler submersible sewage pump through the maximum particle size reached d = 460mm.
