Abstract
The utility model relates to a single-stage horizontal type small-flow and high-lift pump which comprises a pump body, a pump cover, an impeller, an inducer, a pump shaft, a bearing part and a sealing part. The single-stage horizontal type small-flow and high-lift pump is characterized in that a ring-shaped guide vane pumping chamber is arranged between the pump body and the pump cover; and the impeller is arranged in the guide vane ring-shaped pumping chamber and is coaxial with the inducer arranged at the front end of a rotating shaft. The single-stage horizontal type small-flow and high-lift pump has the characteristics of being simple in structure, convenient to install and maintain and high in running efficiency of the pump body, and can meet the requirements of a small-flow and high-lift conveying medium.
Description
Technical field the utility model relates to a kind of pumping unit, especially a kind of single-stage horizontal small flow and high lift pump that is applicable to carry clean and the liquid such as inflammable, explosive, severe corrosive that contain micro-particle.
It is spiral pressurized water chamber that background technique is carried at present the small flow of clean and the media such as inflammable, explosive, severe corrosive that contain micro-particle, the pump housing pumping chamber of high-lift single-stage horizontal pump, impeller adopts closed type structure, because of the designing requirement that flow is little, lift is high, the impeller outlet width of flow path is narrower, delivery chamber throat opening area and outlet bore are less, therefore as adopt common pump structure to have the problems such as pump efficiency is lower.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and guarantees the steadily single-stage horizontal small flow and high lift pump of efficient operation of pump.
For achieving the above object, the utility model single-stage horizontal small flow and high lift pump comprises the pump housing, pump cover, impeller, inducer, pump shaft, bearing part, sealed member, wherein between the pump housing and pump cover, set up the stator annular pumping chamber, impeller is positioned at stator annular pumping chamber and coaxial with the inducer of rotating shaft front end.
After adopting said structure, because pump housing delivery chamber is the annular pumping chamber with stator, impeller adopts multiple-blade full-open type structure, can guarantee the throat opening area of pump impeller import and export area and pump delivery chamber, reduced water-pumping chamber's volume, reduce pump frictional loss and hydraulic loss, improve pump efficiency, can meet the designing requirement of low-flow high-lift.
Characteristics of the present utility model are to have simple in structurely, use installation and maintenance convenient, and pump housing operational efficiency is high, can meet the requirement of small flow, high-lift fed sheet of a media.
The accompanying drawing explanation
The overall structure schematic diagram that Fig. 1 is the utility model single-stage horizontal small flow and high lift pump.
Fig. 2 is for showing stator pumping chamber cross-sectional view as Fig. 1.
Fig. 3 is for showing full-open type multiblade impeller structural representation as Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing for embodiment:
As Fig. 1,2,3 shows, the utility model single-stage horizontal small flow and high lift pump is comprised of the pump housing 3, pump cover 6, impeller 5, inducer 1, pump shaft 7, bearing part, sealed member, wherein between the pump housing and pump cover, along pump shaft, stator annular pumping chamber 2 is installed and is connected with pump cover by anti-reverse screw 4, impeller is positioned at stator annular pumping chamber and coaxial with the inducer of rotating shaft front end.Said structure is different from the spiral pressurized water chamber that existing horizontal one-stage pump adopts, because pump housing delivery chamber is the annular pumping chamber with stator, gate vane channel adopts the machining mode, has improved surface accuracy, and impeller adopts multiple-blade full-open type structure, make runner in opening-wide state, stator spins off from the existing pump housing simultaneously, is conducive to casting and processing, improves surface finishment, reduce resistance, improved the efficiency of pump.And can, according to duty parameter by stator outlet number and size are adjusted the stator curve shape, meet multiple performance requirement.
The utlity model has simple in structurely, use installation and maintenance convenient, pump efficiency is high, can meet the requirement of small flow, high-lift fed sheet of a media.
