Description
Technical field
The present invention relates to water pump structure technical field, particularly submersible pump.
Background technique
The diving sand pump is widely used in all trades and professions blowdowns such as municipal engineering, environmental protection pollution treatment, channel cleanout and power plant's ash disposal (slag), chemical industry, metallurgy, mine.What its structure of existing sand pump adopted is the liquid following formula, install on motor land, pump and motor are by the major axis transmission, because the influence of rigidity, so the degree of depth only is limited in and is no more than 6 meters under the liquid, impeller adopts plain vane, and the look angle is little, lift may satisfy the usage requirement under the special industrial and mineral,, impeller high-lift in order to pursue all designs closed type structure, the flow channel space relative narrower, the particle that gap between impeller cover and the blade is less, some are bigger easily is held, and causes impeller to be blocked, and may rotate, cause motor to burn out.
Summary of the invention
The object of the invention is to design a kind of impeller and is difficult for the nothing obstruction that is blocked, big flow, high-lift diving sand pump.
The present invention includes motor case, be connected the fuel tank of motor case lower end, be connected the pump housing of fuel tank lower end, in motor case, arrange motor stator and rotor, fuel tank is run through in the lower end of described rotor, the underpart is arranged in the pump housing, going up between the top of rotor and fuel tank is provided with spring bearing, between the following top of rotor and fuel tank motive sealing mechanism is set, lower end at rotor connects main impeller, described main impeller is by wheel seat and be shallow at least two blades arranging that burst at the seams and form, lower end at the pump housing connects pump cover, pump cover is formed with the upper base that is connected the liquid entering hole upper end by being arranged on axial liquid entering hole, the upper base of described pump cover from the middle part to sidepiece be to last oblique layout, blade is higher than thickness away from place, wheel seat axle center near the thickness with wheel seat axle center place.
The present invention has removed impeller chimney, forms the full-open type impeller, makes blade overhanging, has superior choke preventing function, can reach high-lift purpose.In addition, because above design has strengthened flow, so, formed high-lift, big flow, do not had and stop up, also the working life of the product of Yan Changing, reduce maintenance, increase work efficiency.
Because have the gap between main impeller and the motive sealing mechanism, the foreign material such as lump that mud is brought into easily are clamped in this gap, cause main impeller to be blocked, and motor is burnt, in addition, silt particle, particle also can be penetrated in the Seal cage, have influenced ordinary production, use.
So the present invention also is provided with sub-propeller between main impeller and motive sealing mechanism, described sub-propeller is nested with on rotor, and fixedlys connected with rotor.When hard thing is brought to gap location between main impeller and the motive sealing mechanism by mud, by sub-propeller it is broken up, separates, force of the outer circumferential motion of hard thing to the pump housing.The present invention can avoid hard thing clamping to cause the phenomenon that main impeller blocked to take place, thereby silt particle, particle can't be penetrated into Seal cage and guarantee the safe in utilization of motor.
In addition, the external diameter of sub-propeller of the present invention is less than the external diameter of main impeller.Purpose is to have increased seal arrangement, and exhausted no-sundries enters Seal cage, thereby pump is normally moved.
What existing sand pump structure adopted is the liquid following formula, and impeller is installed in the lower end of rotor, and impeller sucks the mud of its below that the back is centrifugal discharges to side outlet.Because the long fibre class foreign material that mud is brought into easily are wrapped on the blade of impeller, cause impeller to be blocked, and motor is burnt.
The present invention between adjacent two blades the wheel seat edge and the forward of a blade in this two blades between blade is set.During the cement bonded sand pump work, the forward of each blade cuts, breaks it directly towards the long fibre foreign material, has avoided the phenomenon that long fibre twines blade to take place, and the solid-liquid mixing is passed through freely.
Can the disjunctor setting between above-mentioned blade and described blade, the wheel seat.The disjunctor setting is not only convenient produces, and the bulk strength height, and serviceability is strong.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the lateral view of impeller.
Embodiment
As shown in Figure 1, fuel tank 2 is connected motor case 1 lower end, fuel tank 2 by last top 2-1, sidewall 2-2, push up 2-3 down and constitute, wherein, on push up 2-1 and can constitute with sidewall 2-2 one, following top 2-3 is tightly connected by Sealing and bolt and sidewall 2-2.
The pump housing 3 is connected fuel tank 2 lower ends.Pump cover is connected the pump housing 3 lower ends, and pump cover is formed with the upper base 12 that is connected liquid entering hole 11 upper ends by being arranged on axial liquid entering hole 11.
The upper base 12 of pump cover from the middle part to sidepiece be to last oblique layout, four blade 8-2,8-3,8-4,8-5 are higher than thickness away from place, wheel seat 8-1 axle center respectively near the thickness with place, wheel seat 8-1 axle center.
Between main impeller 8 and motive sealing mechanism 7 sub-propeller 9 is set, sub-propeller 9 is nested with on rotor axis of electric 10, and fixedlys connected by key with rotor axis of electric 10.The external diameter of sub-propeller 9 is less than the external diameter of main impeller 8.
As shown in Figure 2, the uniform involute that is is arranged four blade 8-2,8-3,8-4,8-5 on wheel seat 8-1.
Between the forward of wheel seat 8-1 edge between blade 8-2, the 8-3 and blade 8-2 blade 8-6 is set, blade 8-6 and blade 8-2 and wheel seat 8-1 are the disjunctor setting.
In like manner, the blade 8-7 of setting and blade 8-3 and wheel seat 8-1 disjunctor between the forward of wheel seat 8-1 edge between blade 8-3, the 8-4 and blade 8-3.
Blade 8-8 with blade 8-4 and wheel seat 8-1 disjunctor is set between the forward of wheel seat 8-1 edge between blade 8-4, the 8-5 and blade 8-4.
Blade 8-9 with blade 8-5 and wheel seat 8-1 disjunctor is set between the forward of wheel seat 8-1 edge between blade 8-5, the 8-2 and blade 8-5.
It is the submersible type new structure of one that the present invention has adopted collection blowdown and silt particle, compares with traditional sand pump, its superiority shows as: (1) is not subjected to the influence of the degree of depth under the liquid.(2) flow, lift, efficiency index obviously improve, and type spectrum scope applying working condition point is wideer.(3) adopted full-open type impeller, overhanging formula blade, not only have superior choke preventing function, have more chopping and tear function, can eliminate and long stapledly twine richly, solid-liquid mixes by freely.(4) flow passage components are owing to adopted the high-abrasive material manufacturing, and prolong the working life of pump greatly.(5) design of gland seal device have more rationally, reliable, remove the machine envelope that has adopted Double End, when adding oil sealing, increased sub-propeller one, thereby promptly dynamic seal apparatus, silt particle, particle can't be penetrated into Seal cage and guaranteed the safe in utilization of motor.
Increased that sub-propeller, dynamic seal apparatus, flow passage components adopt that rich chromium cast iron casting, wear-resisting property are more excellent, impeller, blade import adopt the inclined-plane to increase the space, and be designed to that import distortion, cornerite are amplified, performance index obviously improve because be unshrouded impeller, overhanging formula blade, do not have stifled, do not have and twine rich, solid-liquid and mix by freely.
