Abstract
A kind of IS type single stage centrifugal pump combined type shaft seal with self circulation cooling device, relate to centrifugal pump technical field, comprise pump shaft, described pump shaft is provided with close encapsulation chamber, described close encapsulation chamber be externally connected to self-loopa cooler bin, described self-loopa cooler bin is provided with ascending tube and down tube, and described ascending tube and down tube are connected with close encapsulation chamber respectively, be filled with cooling liquid in chamber, pump shaft is cooled.The utility model solves IS type single stage centrifugal pump shaft sealing leakage problem, the working life of mechanical seal is effectively improved, and device context is without the need to being equipped with cooling source system, and especially under water scarcity area and deep layer mine, product can not be subject to should be restricted.
Description
Technical field
The utility model relates to centrifugal pump technical field, is specifically related to a kind of IS type single stage centrifugal pump combined type shaft seal with self circulation cooling device.
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.
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.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of IS type single stage centrifugal pump combined type shaft seal with self circulation cooling device.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of IS type single stage centrifugal pump combined type shaft seal with self circulation cooling device, comprise pump shaft, described pump shaft is provided with close encapsulation chamber, described close encapsulation chamber be externally connected to self-loopa cooler bin, described self-loopa cooler bin is provided with ascending tube and down tube, described ascending tube and down tube are connected with close encapsulation chamber respectively, are filled with cooling liquid in chamber, cool pump shaft;
Described close encapsulation chamber comprises the axle sleeve of pump cover, integrated mechanical sealing and plasma cobalt-based RC alloy, and the axle sleeve of described plasma cobalt-based RC alloy is set on pump shaft, and described integrated mechanical sealing is located between the axle sleeve of pump cover and plasma cobalt-based RC alloy;
