Abstract
The utility model relates to a submerged slurry pump. A transition arc-shaped piece is arranged in a pump body below an impeller of the submerged slurry pump. The two ends of the arc-shaped piece extend into an end opening of a liquid inlet pipe and an end opening of an output pipe respectively. According to the submerged slurry pump, the arranged transition arc-shaped piece enables pumped liquid to bear quite low resistance, and therefore frictional resistance can be reduced; besides, a wear-resistant protective jacket is further arranged on the transition arc-shaped piece so as to prevent the pump body from being damaged too fast, and therefore the service life of the submerged slurry pump can be prolonged.
Description
Technical field
the utility model relates to a kind of slag slurry pump under liquid.
Background technique
all fields such as slag slurry pump under liquid is a kind of get off equipment of pumping liquid of liquid level that is placed on, and it is widely used in mine, metallurgical.Because the liquid that utilizes this kind of slag stock pump to aspirate is the solid water liquid mixture of kind of coarse granule and high concentration mostly, and its corrosivity is more intense, so, when carrying high concentration medium or solid particle mixture with it or containing the liquid of the particle that is corrosive, the wearing and tearing of conveyance conduit and the pump housing be can aggravate, and then main shaft and impeller damaged; And in the time of the intake deficiency of Under Water Pumps, it just can not be worked normally, reason is the filter screen that suction port exists multilayer mostly, the existence of multistorey strainer mesh can make transported substance alluvial in suction place, cause the intake in suction chamber not enough, make the generation vacuum of pump body and increased the vibration of the pump housing, thus the working life of having reduced bearing, but also can produce a large amount of noises.
in order to address the above problem, the Under Water Pumps that No. 2448957Y disclosed name of Chinese patent is called " a kind of improved fluid submerged pump " proposition comprises that the top of base plate is provided with motor, bottom at base plate is provided with the pump housing, and between motor and the pump housing, is provided with the main shaft for drives impeller being arranged in hollow adapter.This Under Water Pumps is for improving its working life, and the dynamic and static ring place above impeller is provided with oil sealing, and its meaning is to utilize oil sealing to solve the wearing and tearing to the pump housing of particle in carried liquid.Although this kind of oil sealing can extend the working life of the pump housing, but because the most easily vulnerable position of the pump housing is feed liquor pipe fitting, because when the liquid being sucked enters in the pump housing from feed liquor pipe fitting, can produce relatively large friction, if the flowing velocity of liquid is obstructed, its too fast damage can be caused, and then the working life of Under Water Pumps can be greatly reduced.
Summary of the invention
task of the present utility model is to provide the slag slurry pump under liquid that a kind of mode of utilizing extension pump body to be easily worn solves the fragile problem of pump.
the slag slurry pump under liquid that the utility model proposes comprises the rotatingshaft being driven by driven unit that is arranged on the pump housing and the impeller that is arranged on rotatingshaft lower end, and be arranged on pump housing bottom with the feed liquor pipe fitting of water strainer and the transfusion pipe fitting that is connected with feed liquor pipe fitting, in the pump housing of described impeller below, be provided with transition arcuate member, the two ends of this transition arcuate member extend to respectively the port position of feed liquor pipe fitting and output pipe fitting.
on described transition arcuate member, be also provided with wear-resistance protective sleeve.
described feed liquor pipe fitting tip portion is provided with single layer filter net.
in the pump housing of the slag slurry pump under liquid that the utility model proposes below impeller, be provided with transition arcuate member, the liquid being sucked is relatively little through the suffered resistance of this transition arcuate member, can reduce surface friction drag, and on transition arcuate member, be also provided with wear-resistance protective sleeve, to prevent the too fast damage of the pump housing, thus the working life that can improve slag stock pump; The entry end of the feed liquor pipe fitting of slag slurry pump under liquid is provided with single layer filter net simultaneously, can avoid bringing the excessive transported substance of volume into the pump housing on the one hand, can avoid on the other hand the problem of intake deficiency.
Accompanying drawing explanation
accompanying drawing 1 is the embodiment's of slag slurry pump under liquid that proposes of the utility model outward appearance cross-sectional view.
Embodiment
referring to Fig. 1, this figure provides the embodiment's of slag slurry pump under liquid that the utility model proposes outward appearance structure.This slag stock pump comprises the pump housing 1, rotatingshaft 2, impeller 3 and transition arcuate member 4.The lower end of the pump housing 1 is wherein provided with coupled logical feed liquor pipe fitting 11, is provided with coupled logical transfusion pipe fitting 12 in the side of the pump housing 1.Rotatingshaft 2 is vertically arranged in bearing housing 5, and its upper end extends bearing housing 5, and by driven unit (not providing in figure), controls it and rotate, and the lower end of rotatingshaft 2 extends in the pump housing 1 and in its end, impeller 3 is installed.Transition arcuate member 4 is arranged on the below of the impeller 3 in the pump housing 1, and transition arcuate member 4 upper surfaces are arcs, and its two ends extend to respectively the port position of feed liquor pipe fitting 11 and output pipe fitting 12.Because transition arcuate member 4 easily makes liquid, tide over, be not subject to slurries wearing and tearing, if want to extend the working life of slag stock pump, can on transition arcuate member 4, wear-resistance protective sleeve be installed, because shape and the transition arcuate member 4 of wear-resistance protective sleeve are basic identical, so, concrete structure in figure, do not provided.In addition, in the pump housing 1 inlet part tip portion, be provided with single layer filter net (not providing in figure), if single layer filter host is deposited in suction place, to solve the problems such as the interior easy generation vacuum of the pump housing 1 and noise are large in order to prevent the transported substance in slurries.
Claims (3)
1. slag slurry pump under liquid, this slag slurry pump under liquid comprises the rotatingshaft being driven by driven unit that is arranged on the pump housing and the impeller that is arranged on rotatingshaft lower end, and be arranged on pump housing bottom with the feed liquor pipe fitting of water strainer and the transfusion pipe fitting that is connected with feed liquor pipe fitting, it is characterized in that: in the pump housing of described impeller below, be provided with transition arcuate member, the two ends of this transition arcuate member extend to respectively the port position of feed liquor pipe fitting and output pipe fitting.
2. slag slurry pump under liquid according to claim 1, is characterized in that: on described transition arcuate member, be also provided with wear-resistance protective sleeve.
3. slag slurry pump under liquid according to claim 1, is characterized in that: described feed liquor pipe fitting tip portion is provided with single layer filter net.
