Abstract
The utility model relates to an electrically driven efficient slurry pump, composed of a pump head, a bracket, a motor and a base. The pump head comprises front and rear pump casings, a front guard board, a rear guard board, a spiral case, an impeller, a sheath, a shaft seal apparatus and other components. The utility model is characterized in that the blades of the impeller are added with smooth twisted transitional edges integrated with the blades from the inlet towards the middle part of the blades. According to the utility model, the traditional cylindrical blades are changed into twisted blades, forming oblique shovel type material accommodating effect at the inlet, such that material is more easily pumped through the inlet of the blades of the impeller. The pumping efficiency has improved more than 5%, compared with that of traditional slurry pump with cylindrical blades, the seal effect is superior, and the no leakage occurs.
Description
Technical field
The utility model relates to a kind of electrically driven (operated) pumping installations, specifically a kind of efficient slag stock pump.
Technical background
Several big field of energy industry---such as production fields such as metal mine, iron and steel, non-metal mine, coal, power plant and chemical industry, all entered a high-speed development period at present.Involved raw materials and production waste etc. in the production process of these production fields, such as ore, coal, slag, lime-ash, cinder etc. mainly is to carry out the liquid formula by the slag stock pump to carry, thereby the use amount of slag stock pump is increasing, and is also just more and more higher to the requirement of its performance index.
Using in the slag stock pump series is ZJ series slag stock pump more widely.ZJ series slag stock pump is to be connected to form by pump head, carriage, motor and base four major parts, parts such as pump case, apron plate, back backplate, spiral case, impeller, sheath and gland seal device before and after the pump head part then includes.Impeller in the pump head and the blade structure in the impeller are the key factors that influences slag stock pump working efficiency and working life.Simultaneously, sealing problem also is the problem that manufacturing person and user paid close attention to of slag stock pump.
The model utility content
The purpose of this utility model just provides the efficient slag stock pump that a kind of working efficiency has further raising, to adapt to the needs of energy industry high speed development.
The utility model is achieved in that a kind of efficient slag stock pump, connect to form by pump head, carriage, motor and base, parts such as pump case, apron plate, back backplate, spiral case, impeller, sheath and gland seal device before and after described pump head includes, improvements are that the blade in the described impeller has additional the level and smooth distortion transition edge that is connected as a single entity with blade from inlet to the blade middle part.Increase just can make the cylinder blade of traditional slag stock pump be transformed into twisted blade after should smoothly twisting the transition edge.The inlet of cylinder blade is generally straight flange, after increase should smoothly be twisted the transition edge, just can form a kind of pocket material effect of similar oblique shovel in the inlet of blade, makes the easier import by blade in the impeller of material enter runner, thereby is pumped away.Experiment by repeated multiple times shows that the utility model can have better pumping effect, and pumping efficiency can improve more than 5% than traditional slag stock pump of cylinder blade.
The utility model also can be realized like this: on the basis of the above, in described pump head, bulge loop outside contacting of joining of apron plate and back backplate and spiral case is shaped on the conical surface, along being pressed on the loop side plane of spiral case both sides respectively, the outer bulge loop interior angle on described apron plate and back backplate is provided with " O " RunddichtringO in the ring of made outer bulge loop.
Pump head apron plate and the back backplate and spiral case of existing ZJ series slag stock pump is conical surface grafting and the exterior edge face is concordant, is respectively equipped with " O " RunddichtringO in the outside of the seam crossing of two circles, and this two seal ring compresses sealing by the forward and backward pump case of periphery respectively.In use, the forward and backward backplate of pump head deform with the exterior edge face regular meeting of spiral case connecting part and be difficult to concordant, thereby the sealing configuration of this outer pressure seal ring just cause through regular meeting poorly sealed, thereby make slag stock pump appearance leakage, influenced working environment.
After spiral case was lived in bulge loop and crimping outside the utility model was made respectively, just can make the bi-side indentation of spiral case on forward and backward backplate, not contact with the forward and backward pump case of periphery; And the sealing configuration of " O " RunddichtringO of this crimping form of apron plate and back backplate and spiral case and bulge loop angle setting outside; can realize the reliable sealing of this joint; thereby the leakage problem that has suppressed the slag stock pump has effectively been protected the clean and tidy of working environment.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the external structure schematic representation of slag stock pump.
Fig. 2 is the improved blade wheel structure schematic representation of the utility model.
Fig. 3 is the improved pump head sealed structural representation of the utility model.
Embodiment
As shown in Figure 1, the overall structure of this efficient slag stock pump is identical with the structure of traditional slag stock pump, is promptly connected to form by pump head 1, carriage 2, motor 3 and base 4 these four parts.Referring to Fig. 3, the pump head of this efficient slag stock pump partly is to be connected to apron plate 11 and back backplate 12 in spiral case 13 both sides, is connected to impeller 14 in the spiral case 13, preceding protect, the periphery of back backplate be connected to before and after pump case and sheath and gland seal device etc.
As shown in Figure 2, the impeller in the utility model pump head and the structure of conventional impellers are basic identical, the blade 14 in the impeller 14 ' be to set up level and smooth distortion transition along 15 to the blade middle part just from runner inlet, this smoothly twist transition along 15 with blade 14 ' be connected as a single entity.Grope through testing repeatedly, the length of smoothly twisting the transition edge accounts for 30-40% of blade length overall, and the effect of distortion angle in the time of 30-40 ° is the most excellent.
As shown in Figure 3, pump head of the present utility model is the ring edge that is shaped on evagination in the male cone (strobilus masculinus) end of apron plate 11 and back backplate 12, the inner side surface on two outer bulge loop edges is pressed in respectively on the ring plane of spiral case 13 both sides, the interior angle place on the outer bulge loop edge on apron plate 11 and back backplate 12 is provided with " O " RunddichtringO 16 respectively, seals the seam of this joint.
