Description
Technical field
The utility model relates to centrifugal pump technical field, is specifically related to a kind of mining super many type of series centrifugal pump.
Background technique
Current mine adopts wear-resisting multistage centrifugal pump as production main pumping equipment usually, the water pump shaft of wear-resisting multistage centrifugal pump adopts cylindrical roller bearing as two end supports, cylindrical roller bearing adopts grease or thin oil lubricant, can keep good working state when this supporting structure is run under running in atmosphere and being also namely in dry type operating mode.For water pump MD580-60 × 4, the wherein 580 flow Q representing water pump, the 60 single-stage lift H representing water pump, 4 progression representing water pump, so the flow of this model water pump is 580M
3/ h, lift is 240m.Original multi-stage centrifugal pump, by the restriction of progression, only has at most 10 grades, if increase progression again, pump shaft increases along with progression increases Oscillation Amplitude, even can fracture, and the operational efficiency of pump reduces, the lost of life.
As Chinese patent (CN102536876A) discloses a kind of water pump shaft support device for multistage centrifugal pump, have employed the spring bearing of sliding bearing as water pump shaft end, adopt water to carry out lubrication to sliding bearing simultaneously, not only reduce noise and the temperature rise of sliding bearing, and substantially increase mechanical efficiency and the operational reliability of sliding bearing.But this water pump supporter device still can not meet the centrifugal water pump job requirement being greater than 10 grades.
For another example Chinese patent (CN103742438A) discloses a kind of multistage centrifugal pump rotating-shaft support devices, and the endoporus of the pump housing, pump cover adopts, and to be benchmark with pump spindle center line move down eccentric processing structure.Have that structure is simple, convenient and practical, failure rate is low, working efficiency high, overcome the adverse effect that the deflection of rotating shaft coaxality runs pumping unit, ensure pumping unit smooth running.Same this water pump supporter device still can not meet the centrifugal water pump job requirement being greater than 10 grades.
For another example Chinese patent (CN101737335A) discloses a kind of high-lift multi-stage centrifugal pump, and be welded with cobalt-based RC alloy-layer by piling respectively on balance hoop and balance plate rubbing surface each other, the thickness of cobalt-based RC alloy-layer is 6-8mm.Under the prerequisite that thickness is constant, just can make nearly double the working life of Equilibrator, namely be increased to 7000 hours by former 4000 hours.But the multistage centrifugal pump that contrast works in the presence of a harsh environment is also not suitable for.
