Description
Technical field:
The utility model relates to a kind of multistage deep well submerged pump impeller and locking mechanism, belongs to the pump part assembly and makes the field.
Background technique:
Existing multistage deep well submerged pump impeller and locking mechanism are made of its deficiency foundry goods: the one, and body weight; The 2nd, because impeller channel is coarse, fluid pressure loss in process of flowing is big, efficient is low; The 3rd, corrosion-resistant, the time is long slightly, easily produces corrosion, and the resistance of start increases greatly, and the excessive phenomenon of burning of electric motor starting electric current easily takes place; The 4th, the spline linkage structure that impeller and pump shaft adopt, its locking property and poor stability.
Summary of the invention:
Purpose of design: avoid the deficiency in the background technique, the one, multistage deep well submerged pump impeller adopts stainless steel punching press assembly welding structure, the 2nd, adopt the taper Tensioning structure between impeller and pump shaft, make impeller and pump shaft form tensioner securely and be connected, to guarantee its stability of rotation.Design proposal: in order to realize above-mentioned purpose of design, the one, the impeller in the Submerged Motor Pumps adopts corrosion resistant plate and the moulding of press tool punching press assembly welding, and purpose is to alleviate under the prerequisite of impeller body weight, guarantees that it has good intensity; The 2nd, the finished product high conformity is adjusted for the quick tensioner assembling of impeller provides QA Quality Assurance and need not; The 3rd, adopt taper sheath tensioner locking structure, guaranteed reliable and stable being connected between impeller and pump shaft.Its technological scheme: 1. multistage deep well submerged pump impeller is made of front shroud of impeller (2), blade (3), impeller spacer (6) and back shroud of impeller (7), be blade (3) between front shroud of impeller (2) and back shroud of impeller (7), impeller spacer (6) is positioned on the back shroud of impeller (7), and the axis hole in its impeller spacer (6) is relative with axis hole in the back shroud of impeller (7) and constitute the impeller axis hole.2. the multistage deep well submerged pump impeller locking mechanism that constitutes by multistage deep well submerged pump impeller, impeller sleeve (4) is positioned at the impeller axis hole, pump shaft (1) is positioned at impeller sleeve (4), and impeller nut is screwed in impeller sleeve (4) and goes up and impeller is locked on the pump shaft (1).
The utility model is compared with background technique, and the one, adopt stainless steel to make multistage deep well submerged pump impeller and locking mechanism, not only body is light, and intensity is good, and energy loss is minimum, efficient is high; The 2nd, solved the corrosion that background technique exists and the current of electric excessive deficiency of burning even can't start work that causes; The 3rd, the high conformity of parts is convenient to quick assembling, is need not to adjust; The 4th, adopt the taper sheath with impeller and the tensioner locking structure that pump shaft forms, not only guaranteed reliable connection the between impeller and pump shaft, and guaranteed that impeller rotates reliability.
