Manufacturers supply DM type mine with multi-stage centrifugal pump a neutral mineral water, DM type mine multistage centrifugal pump Product Overview DM type mine with multi-stage pump for conveying solid particle content of not more than 1.5% (particle size less than 0.5 mm) and other similar sewage transmission medium temperature is not more than 80 ℃, suitable for steel mills, mine drainage, sewerage and other occasions. Two, DM type mine multistage centrifugal Features mine multistage centrifugal pump for multistage, suction in the water segment, into a horizontal direction, the water outlet section vertically upward, it can lift Depending on needs and increase or decrease the pump series. Multistage centrifugal pump assembly is good or not, the impact on the performance of a great relationship, especially in the mouth of each impeller and guide wing and out of the center, which is about to make a slight deviation of the pump flow is reduced, reducing lift poor efficiency, so the repair assembly Be sure to pay attention to when. Three, DM type mine multistage centrifugal pump DM product structure consists of a fixed part, the rotor parts, bearings and shaft seals four major components: a fixed part, by inhalation, middle, spit segment and guide vanes and other components with a wear bar will tighten each segment constitutes studio. DM-type pump outlet vertically upward, the inlet is generally horizontal direction, according to need to produce entrance vertically upward direction. 2, mainly by the rotor shaft, impeller, balance disc and sleeve and other components. Impeller shaft transfers power to make it work; axial force is balanced by disc; shaft equipped with replaceable bushings to protect shaft. 3, bearing by bearing part of the main body, bearings and other components gland. Except 85-67,155-67,600-60 type pump with sliding bearings, thin oil lubrication, the rest are used pump bearings, dry oil lubrication. 4, the seal is generally soft packing seal, mainly by water segment and end cap sealing casing, packing, retaining rings and other components. Seal cavity leads to a certain pressure of water from the water seal, water-cooled and water lubrication. DM from the pressure of the water pump or external water pump. DM-type pump more mechanical seal. Drive pump through flexible coupling directly driven by a prime mover. From motor end pump, the pump is clockwise. Four, DM type mine multistage centrifugal pump Model Description Example: DM150-30 × 2 DM- wearable multistage centrifugal pump design point flow 150- 150m3 / h 30- single-stage pump designed head is 60m 2- pump The Series 2
