Abstract
The utility model belongs to the technical field of stealthily defile the technique of pump part and specifically relates to a high -lift stealthily balanced type device of dirty pump, including the pump seat and with pump seat fixed connection's the pump body, the pump body in be provided with grease chamber and motor shaft, the motor shaft on fixed mounting have the impeller, the inner wall of grease chamber on be provided with wear -resisting circle, the inner wall of pump seat on be provided with down wear -resisting circle, upper end and the last wear -resisting circle of impeller contact, the lower extreme of impeller contacts with wear -resisting circle down. This high -lift stealthily balanced type device of dirty pump has solved traditional stealthily dirty pump lift and has generally used limited problem no longer than 30 meters, and it is regional to have widened latent dirty pump lift to enlarge the stealthily application range of dirty pump.
Description
Technical field
The utility model relates to the technical field of submerged pump parts, especially a kind of balance device of high-lift submerged pump.
Background technique
In city water, urban sewage and industrial wastewater treatment system, submerged pump is a kind of common sewage lifter.But, traditional submerged pump is due to self structure reason, the lift of general submerged pump is limited in less than 30 meters, those often need more high-lift sewage pump under needing that liquid is passed to the operating mode of more remote and higher liquid level, multistage centrifugal pump or multiple stage series connection of pumps is generally adopted to use for the more high-lift occasion of needs, but multistage pump is generally multiblade impeller structure, easily blocks, this operating mode of conveying sewage is not well suited for; The relay of multiple stage pump runs the investment then strengthening Infrastructure, and operation management is very inconvenient.
Model utility content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provide a kind of balance device of high-lift submerged pump, solves traditional submerged pump lift and is generally no more than 30 meters of use limitation problem.
The utility model solves the technological scheme that its technical problem adopts: a kind of balance device of high-lift submerged pump, the pump housing comprising pump seat and be fixedly connected with pump seat, grease chamber and motor shaft is provided with in the described pump housing, described motor shaft is installed with impeller, the inwall of described grease chamber is provided with wear-resisting ring, the inwall of described pump seat is provided with lower wear-resisting ring, and the upper end of described impeller contacts with upper wear-resisting ring, and the lower end of impeller contacts with lower wear-resisting ring.
Further, the impeller described in technique scheme is fixedly mounted on motor shaft by key and impeller fastening piece.
Further, assembled mutually by integrated mechanical sealing between the motor shaft described in technique scheme and grease chamber.
Further, the flowing back shroud of the impeller described in technique scheme evenly offers several equalizing orifices.
The beneficial effects of the utility model are: the balance device of high-lift submerged pump of the present utility model, solve the stressed unbalanced problem of impeller of traditional submerged pump, reduce the working pressure problem of mechanical seal, improve impeller runs up while balance, also submerged pump lift region has been widened, solve traditional submerged pump lift and be generally no more than 30 meters of use limitation problem, thus expand the using scope of submerged pump.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, pump seat, 2, lower wear-resisting ring, 3, the pump housing, 4, impeller, 5, impeller fastening piece, 6, upper wear-resisting ring, 7, key, 8, grease chamber, 9, motor shaft, 10, integrated mechanical sealing, 11, equalizing orifice.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The balance device of the high-lift submerged pump of the utility model as shown in Figure 1, the pump housing 3 comprising pump seat 1 and be fixedly connected with pump seat 1, grease chamber 8 and motor shaft 9 is provided with in the pump housing 3, motor shaft 9 is installed with impeller 4, the inwall of grease chamber 8 is provided with wear-resisting ring 6, the inwall of described pump seat 1 is provided with lower wear-resisting ring 2, and the upper end of impeller 4 contacts with upper wear-resisting ring 6, and the lower end of impeller 4 contacts with lower wear-resisting ring 2.Because upper and lower two ends coordinate with upper wear-resisting ring 6 and lower wear-resisting ring 2 simultaneously when impeller 4 runs up, stress is better, and the impeller 4 solving traditional submerged pump, by force unbalance, reduces the working pressure problem of mechanical seal.
Wherein, impeller 4 is fixedly mounted on motor shaft 9 by key 7 and impeller fastening piece 5.Assembled by integrated mechanical sealing 10 phase between motor shaft 9 with grease chamber 8, the integrated mechanical sealing 10 that selection work pressure is higher, its structure is simple, floatability is good, spring adopts the big spring structure of anti-clogging, static, and completely by fed sheet of a media lubrication and seal face, medium contains heat radiation and the wearing and tearing of the concentration decision sealing surface of solid particle, by adopting the particular design of low spring pressure and sealing surface structure, meet the usage requirement of mechanical seal with this.The flowing back shroud of impeller 4 evenly offers several equalizing orifices 11, several equalizing orifices 11 lay down the impact force of part flowing water to impeller 4, impeller 4 is worked in the state of the equilibrium, and several equalizing orifices 11 make integrated mechanical sealing 10 working pressure reduce simultaneously, ensure sealing reliability.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
