Sewage pump characteristics and application analysis
Submersible sewage pump features ①The use of a unique single-leaf or double-vane impeller structure, greatly improving the ability to pass dirt, can effectively pump 5 times the diameter of fiber material and the diameter of the pump diameter of about 50% of the solid particles. ② mechanical seal with a new type of hard and decay resistant tungsten carbide material, while the seal improved double seal, so that it is long-term oil chamber operation, the pump safe and continuous operation of more than 8000 hours. ③ The overall structure is compact, small size, small noise, significant energy-saving effect, easy maintenance, without the need to build pump room, dive into the water to work, greatly reducing project costs. ④ The pump seal oil chamber is equipped with high-precision anti-interference leakage detection sensor, and stator windings embedded in the thermal components, absolute protection of the pump motor. ⑤ According to user needs with automatic safety control cabinet, the pump leakage, leakage, overload and over-temperature protection, etc., to improve product safety and reliability. ⑥ float switch can be based on changes in liquid required to automatically control the pump start and stop, without special care, the use of extremely convenient. ⑦ According to user needs with dual rail automatic coupling installation system, which brings great convenience to installation and maintenance, people do not have to enter the sewage pit for this purpose. ⑧ can be used in the whole range, and to ensure that the motor will not be overloaded. ⑨ There are two different installation methods, fixed automatic coupling installation system, mobile free installation system. Sewage pump in the structure and performance of self-priming sewage pump, draw lessons from the advantages of similar products at home and abroad, and in many ways to absorb the user's requirements and provide improved advice, developed from the self-absorption and sewage in one, that is Like ordinary water self-priming pump does not need safety valve, do not lead irrigation, but also suction containing large solid block, long fiber dirt, sediment, waste ore impurities, excrement disposal and all engineering sewage and plastic Quality liquid; Sewage pump the use of: ①business unit wastewater discharge. ② urban sewage treatment plant discharge system. ③ subway, basement, air defense system drainage station. ④ hospitals, hotels, high-rise building sewage discharge. ⑤ residential sewage drainage station. ⑥ municipal engineering, construction sites in the discharge of slurry. ⑦ water plant water supply device. ⑧ farm wastewater discharge and rural farmland irrigation. ⑨ exploration of mining and water treatment equipment package. ⑩ instead of shoulder picking people, to send the river mud. Sewage Discharge Pump According to the different ways, sewage pump can be divided into self-suction sewage pump, liquid sewage pump, with a knife-type sewage pump and automatic mixing sewage pump. It is widely used in mines, papermaking, printing and dyeing, environmental protection, oil refining, petroleum, chemical industry, farm, dyeing because of its characteristics of conveying liquids containing hard solids, fibrous materials and especially dirty, sticky and slippery liquids , Brewery, food, fertilizer, coking plant, construction, marble factory, mud, quicksand, mud ponds, sewage ponds, dirty liquid to send thick liquid, filling and suspended matters in the sewage treatment. Sewage Pump Selection and Maintenance: The most critical issue for sewage pumps is the reliability issue, because the medium that needs to be transported is a mixture of liquids containing solid materials. This problem makes the sewage pump in the seal, the motor carrying capacity, bearing arrangement and Selection and other requirements than the average pump to be high, so the selection, we must understand clearly the sealing pump reliability and carrying capacity.
