Underground pump explosion-proof explosion-proof underground sewage pump is a kind of explosion-proof submersible sewage pump, is the danger of methane or coal dust explosion in coal mining face drainage, coal mine shaft, inclined shaft drainage construction, The bottom main drainage, the main shaft bottom loose coal bunker automatic drainage, Laotang, unmanned area gushing automatic drainage, underground coal mine dust, sediment and other smaller solid particles of groundwater discharge, water storage drainage, emergency rescue drainage, the city Environmental system sewage treatment. Underground explosion-proof sewage pump in our daily life plays a decisive role, it should arouse our attention, the following Xiaobian underground explosion-proof sewage pump provides a detailed interpretation. First, underground explosion-proof sewage pump model significance Second, the underground explosion-proof sewage pump structure features a unique structure and a new type of mechanical seal, can effectively contain solids and long fibers. Impeller Compared with the traditional impeller, explosion-proof submersible pump impeller single or dual flow channel form, similar to a section of the same size elbow, has a very good overcurrent, with a reasonable volute, making the pump has the efficiency High, impeller static and dynamic balance test, the pump in the operation without vibration. Third, the underground explosion-proof sewage pump Product Features 1, according to user needs with automatic safety control cabinet, the pump leakage, leakage, overload and over-temperature and other absolute protection, improve product safety and reliability. 2, the beginning of the float can change according to the desired level, automatic control of the pump start and stop, without special care, the use of extremely convenient. 3, 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. 4, can be used in the whole head range, and to ensure that the motor will not be overloaded. 5, there are two different installation methods, fixed automatic coupling installation system, mobile free installation system. 6, The unique single-blade or double-vane impeller structure greatly improves the ability of dirt to pass through, and can effectively pass fiber material which is 5 times of the pump diameter and solid particles whose diameter is about 50% of the pump diameter. 7, the mechanical seal with a new type of hard corrosion-resistant tungsten carbide as the material, while improving the seal to double-ended seal, making it long-term operation in the oil chamber, the pump can run safely for more than 8000 hours. 8, 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. 9, sealed oil chamber is equipped with high-precision anti-interference leakage detection sensor, and stator windings embedded in the thermal components, the pump motor absolute protection. Fourth, underground explosion-proof sewage pump conditions Explosion-proof submersible pump medium temperature does not exceed 60 ℃, the medium weight is 1-1.3kg / dm3, PH value in the range of 5-9. Explosion-proof submersible pumps without internal circulation cooling system pump, the motor part of the exposed surface does not exceed 1 / Explosion-proof submersible pump main parts of the material is cast iron, it can not be used to pump highly corrosive liquids. Underground explosion-proof sewage pump is based on the introduction of foreign advanced technology combined with the use of domestic sewage pump features the successful development of a new generation of pump products, with significant energy saving, anti-winding, non-blocking, automatic installation and automatic control and so on. Above is a detailed interpretation of underground explosion-proof sewage pump, including underground sewage pump model significance, structural characteristics, product features, conditions of use of these aspects, hope to help you follow-up better use of underground explosion-proof sewage pump.
