Let's Discuss The Four Major Components Of Horizontal Mining Sewage Pumps

　　To discuss the four components of the horizontal mining sewage pump　　Horizontal mining sewage pump is a hydraulic model of energy-saving products used. After continuous update and development, it has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, easy installation and maintenance, and long operating life, and the product performance is reliable.It is used to transport neutral ore water (particle size less than 0.5 mm) and other sewages with solid particles content not more than 1.5%, and the temperature of the conveyed medium is not more than 80℃. It is suitable for steel plants, mine drainage, sewage transportation and other occasions.Horizontal mining sewage pump mainly consists of four parts: stator, rotor, bearing and shaft seal: 1. The stator part is mainly composed of suction section, middle section, discharge section, guide vane, etc., and each section is clamped with tension bolts to form a studio.2. The rotor part of this series of pumps is mainly composed of a shaft and impeller, sleeve, balance disc and other parts installed on the shaft. The number of impellers depends on the number of pump stages.The parts on the shaft are tightened by flat keys and shaft nuts to connect them to the shaft.The entire rotor is supported by rolling bearings or sliding bearings at both ends. The bearings vary according to the model and do not bear axial force, and their axial force is balanced by a balance disc.The horizontal mining sewage pump allows the rotor to swim axially in the pump housing during operation, and cannot use centripetal ball bearings.Rolling bearings are lubricated with greasy, sliding bearings are lubricated with dilute oil, and self-lubricated with oil rings, and circulating water is cooled.The sealing surfaces between the water inlet, middle and outlet sections of the pump are sealed with molybdenum disulfide grease, and sealing rings, guide vane sleeves, etc. are installed between the rotor part and the fixed part for sealing. When the wear degree of the sealing ring and guide vane sleeve has affected the working performance of the pump, it should be replaced.3. The bearing part includes two types: rolling bearing and sliding bearing: rolling bearing is mainly composed of bearing body, bearing and bearing cap, etc., and is lubricated with grease.The sliding bearing is mainly composed of a bearing body, bearing cover, bearing shell, dustproof disc, oil level gauge, oil swing ring, etc., and is lubricated with thin oil.The sealing forms of shafts are mechanical seals and packing seals.When horizontal mining sewage pumps are sealed with packing, the position of the filler ring must be correctly placed, the tightness of the filler must be appropriate, and the liquid can seep out drop by drop.Various sealing elements of the pump are installed in the sealing chamber, and a certain pressure of water must be passed into the chamber, and water sealing, water cooling or water lubrication are allowed.A replaceable bushing is installed at the shaft seal to protect the pump shaft.4. The shaft seal uses a packing seal, which is mainly composed of a sealing box, filler and waterproof ring on the water inlet section and the packing box.Seal the liquid in the work room and acts as water sealing, water cooling and water lubrication. The water sealing water comes from pressure water in horizontal mining sewage pumps.
