Submersible sewage pump vertical layout, coaxial pump and motor, the use of unique single or double vane impeller structure, greatly improving the dirt through capacity, with high efficiency, anti-wrap, non-blocking, automatic coupling, high reliability and automatic Control and other advantages, in the delivery of solid particles and long fiber waste, has a unique function. Mainly used for municipal engineering, industry, hospitals, buildings, hotels, restaurants and other industries. For the delivery of solid and long fibers of various silt, wastewater, urban sewage (including corrosive, aggressive media occasions). Submersible sewage pump selection points 1, must be selected in strict accordance with the international ISO 9906 or the current relevant standards of manufacturing production, and through the comprehensive performance test authority submarine submersible pump brand. 2, when there are multiple brands of products to choose from, it is necessary for the main components of submersible sewage pump material, processing accuracy, equipment appearance, over-flow components essential features (large channel, anti-wrapping, anti-clogging, etc.) and additional features Long fiber cutting and tearing, automatic mixing to prevent dirt settling plate knot, etc.), suppliers promised no end of service life, after-sales service, quotes and other aspects of a comprehensive comparison, preferred use. Indoor sewage pond should be installed sealed manhole cover, set the vent. 3, if the submersible sewage pump is used to pump the erosive waste water, the pump body should be made of corrosion-resistant materials such as stainless steel. 4, According to user needs with automatic safety control cabinet, the pump leakage, leakage, overload and over-temperature monitoring, to ensure reliable and safe pump operation. 5, according to user needs to promote discharge of sewage (waste) water, water and sewage pool (water collection wells) set up the location, to determine the submersible sewage pump flow and lift required to determine the pump specifications. 6, building outdoor sewage tank can be installed non-closed manhole cover, no ventilation tube. 7, according to the characteristics of sewage, waste water, the choice of pump type, whether the need to use cutting grinding, is the choice of whirlpool impeller is still flow impeller, is still a single runner dual runner (same premise, single runner than the dual flow Road anti-blocking function is better). 8, the selection should be aware of the submersible sewage pump in normal use under the premise of the uniform barrier-free working hours, mechanical seal life, bearing life, motor design life, motor insulation level, the motor should be able to withstand the number of starts and stops per hour. Airtight covers are gray cast iron, cast aluminum and ductile iron three. 9, basement submersible sewage pump should be set up dual power to prevent power failure. 10, Submersible sewage pump should have leakage protection devices and overheating or overload protection device, a sealed leak monitoring device and a reliable grounding device. 11, F-class stator insulation, equipped with thermal protection components. Conditions of use 1, the medium temperature shall not exceed 60 ° C, severe 1.0 ~ 1.3kg / dm3, PH value in the range of 5 ~ 9. 2, no self-flow circulating cooling system pump, the motor part of the surface exposed no more than 1/3. 3, under normal circumstances, the pump must be used within the scope of the use of head to ensure that the motor is not overloaded, if you need to use in the whole range, should be specified when ordering, in order to manufacturers. 4, the pump motor current during operation should not exceed the rated current of the motor. 5, submersible sewage pump motor rated voltage 380V, frequency 50HZ three-phase AC power supply (other voltage and frequency requirements can be customized).
