Abstract
A kind of liquid following formula shurry pump, comprise the pump housing, bearing housing, impeller, described impeller is fixedly connected on pump shaft by the cooperation of impeller nut, key B and stopping shim, and the bearing A on the left of described bearing housing is sleeve bearing, and the bearing B on the right side of described bearing housing is biserial deep groove ball bearing; Pump shaft head in the described pump housing is provided with pump coupling, and described pump coupling is connected in motor coupler by key A and elastomer block.The utility model structural design is simple, and noise is low, spin stabilization, and working life have also been obtained lifting.
Description
Technical field
The utility model relates to the industrial pump that a kind of conveying has corrosivity and has abrasiveness liquid and suspension, relates in particular to a kind of liquid following formula shurry pump.
Background technique
Shurry pump is one of key equipment in the operations such as well cementation, pressure break, acidifying, and it also plays an important role in the industries such as petrochemical industry, coal gas chemical engineering, power station, mining, boats and ships.Slurry pump belongs to reciprocating pump, energy transfer of highly viscous, high sand content and the liquid containing tempering property solid particle, but current slurry pump flow is smaller, instantaneous flow and pump pressure are pulsation, and easily damaged parts is more, and noise is large and rotation is unstable, maintenance load is large, and working life is short.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of structural stability, long service life liquid following formula shurry pump.
The utility model realizes like this, a kind of liquid following formula shurry pump, comprise the pump housing, bearing housing, impeller, described impeller is fixedly connected on pump shaft by the cooperation of impeller nut, key B and stopping shim, thus pump shaft and impeller are connected, prevent from being broken because of impeller loose or dislocation during reversion.
Bearing A on the left of described bearing housing is sleeve bearing, and the bearing B on the right side of described bearing housing is biserial deep groove ball bearing; It is little that biserial deep groove ball bearing holds friction factor, and vibration and noise is also lower, and can bear certain thrust load, improves the working life of bearing.Pump shaft does not establish bearing in liquid lower portion, to adapt to carry the medium containing solid particle.
Pump shaft head in the described pump housing is provided with pump coupling, and described pump coupling connects and motor coupler by having key A and elastomer block, pump coupling and motor coupler centring concentric, coaxality 0.1mm, faces parallel 0.3mm.
Described impeller is the unshrouded impeller of band backward vane, manufactures simple, easy to clean, is applicable to carry the material containing larger particles suspended matter, not easily blocks.
The utility model structural design is simple, and noise is low, spin stabilization, and working life have also been obtained lifting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
In figure 1, lower linking tube, 2, protecgulum, 3, the pump housing, 4, connection bracket, 5, support tube, 6, pump shaft, 7, base plate, 8, bearing A, 9, bearing housing, 10, bearing B, 11, pump coupling, 12, elastomer block, 13, motor coupler, 14, motor cabinet, 15, elbow, 16, drain pipe, 17, lower flange, 18, upper flange, 19, key A, 20, impeller, 21, pump cover, 22, impeller nut, 23, stopping shim, 24, key B.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of liquid following formula shurry pump, comprise the pump housing 3, bearing housing 9, impeller 20, it is characterized in that: described impeller 20 is fixedly connected on pump shaft 6 by the cooperation of impeller nut 22, key B24 and stopping shim 23, bearing A8 on the left of described bearing housing 9 is sleeve bearing, and the bearing B10 on the right side of described bearing housing 9 is biserial deep groove ball bearing; Pump shaft 6 head in the described pump housing 3 is provided with pump coupling 11, and described pump coupling 11 connects and motor coupler 13 by having key A19 and elastomer block 12; Described impeller 20 is the unshrouded impeller of band backward vane.
During concrete enforcement, fluid is after lower linking tube enters, centrifugal force is produced by driven by motor impeller High Rotation Speed, certain centrifugal force is produced when liquid turns round with impeller in pump, outwards get rid of the ring runner in pump case, and under the restriction of flow channel shape, be forced to backflow, again enter another leaf road below from root of blade.Liquid energy continuous several times enters between blade and obtains energy, to the last discharges from drain pipe.
This new pump is applicable to carry the liquid and the suspension that have corrosivity He have abrasion, as carried phosphoric acid material pulp in phosphamidon engineering, and its performance range: flow Q=7 ~ 400m
3/ h, lift H=50m.
