Abstract
A thread anti-loosening structure for impellers of a centrifugal pump relates to the centrifugal pump; the impellers are arranged on a pump shaft through flat keys; threads with the same rotating direction are arranged on the pump shaft of the two sides of the impellers; common shaft sleeves are arranged on the pump shaft at one sides of the impellers, which are matched with the threads; anti-rotating shaft sleeves are arranged at the other sides of the impellers; key grooves of the shaft sleeves are arranged at one ends of the anti-rotating shaft sleeves; one ends of the flat keys are arranged in the key grooves of the shaft sleeves; each liquid pump is provided with a pump shaft; and therefore, the storage amount is little, and the manufacturing cost is low; when the steering direction of the pump is needed to be adjusted in a using field, only the common shaft sleeves and the anti-rotating shaft sleeves are needed to be exchanged and arranged, a counter-rotating shaft is not needed to be reordered; and the anti-loosening structure has the advantages of low cost, short period and convenience in replacement.
Description
Technical field
The present invention relates to centrifugal pump, is a kind of centrifugal pump impeller locking thread structure specifically.
Background technique
We know; Existing centrifugal pump impeller locking thread structure is on pump shaft, to be provided with impeller through flat key, and the pump shaft of impeller both sides is provided with the screw thread of two kinds of counterturns; On the pump shaft with the threaded sleeve that is provided with of threads engaged; During pump work, the screw-thread fit on threaded sleeve and the pump shaft is more and more tighter, produces effect to prevent that impeller is loosening.This anti-loose structure, when turning to of centrifugal pump need be adjusted to counter-rotating, loosening in order to prevent threaded sleeve and impeller; Need be replaced by the counter-rotating pump shaft, the screw thread of counter-rotating on the pump shaft with just changeing screw thread switched in opposite on the pump shaft, every centrifugal pump is equipped with two pump shafts; Quantity in stock is big, and manufacture cost is high, when the scene of using needs the adjustment pump to turn to; Must order a reversing shaft again, cost is high, the cycle is long, and changes inconvenient.
Summary of the invention
The technical problem that the present invention solves is, solves two pump shafts of every centrifugal pump outfit, and quantity in stock is big; Manufacture cost is high, when the scene of using needs the adjustment pump to turn to, must order a reversing shaft again; Cost is high, the cycle is long, and changes inconvenient problem, provides a kind of every centrifugal pump to be equipped with a pump shaft; Quantity in stock is little, and low cost of manufacture is when the scene of using needs the adjustment pump to turn to; Need not order a reversing shaft again, cost is low, the cycle is short, and easy to operate centrifugal pump impeller locking thread structure.
Technological scheme of the present invention is that a kind of centrifugal pump impeller locking thread structure is provided with impeller through flat key on pump shaft; The main structure characteristics are; The pump shaft of impeller both sides is provided with and turns to identical screw thread, is provided with common axle sleeve with threads engaged impeller one side on the pump shaft, and opposite side is provided with the anti-rotation axle sleeve; Anti-rotation axle sleeve one end is provided with the axle sleeve keyway, and an end of flat key is in the axle sleeve keyway.
The invention has the beneficial effects as follows, turn to identical screw thread, be provided with common axle sleeve with threads engaged impeller one side on the pump shaft because the pump shaft of impeller both sides is provided with; Opposite side is provided with the anti-rotation axle sleeve, and anti-rotation axle sleeve one end is provided with the axle sleeve keyway, and an end of flat key is in the axle sleeve keyway; Every centrifugal pump is equipped with a pump shaft, and quantity in stock is little, low cost of manufacture; When scene of using needs the adjustment pump to turn to, only need common axle sleeve and anti-rotation axle sleeve be exchanged installation and get final product, need not order a reversing shaft again; Cost is low, the cycle is short, and changes conveniently.
Description of drawings
Accompanying drawing is a kind of structural representation of the present invention, also is a kind of embodiment's schematic representation.
Embodiment
Centrifugal pump impeller locking thread structure as shown in the figure; Be provided with impeller 2 through flat key 3 on the pump shaft 4; The pump shaft 4 of impeller 2 both sides is provided with and turns to identical screw thread, is provided with common axle sleeve 5 with threads engaged impeller 2 one sides, and opposite side is provided with anti-rotation axle sleeve 1; Anti-rotation axle sleeve 1 one ends are provided with the axle sleeve keyway, and an end of flat key 3 is in the axle sleeve keyway.Common axle sleeve relies on the rotation of pump shaft locking, and the anti-rotation axle sleeve relies on the flat key in the axle sleeve keyway locking, when the scene of using needs the adjustment pump to turn to; Only need that common axle sleeve and anti-rotation axle sleeve are exchanged installation and get final product, pump shaft of every centrifugal pump outfit, quantity in stock is little; Low cost of manufacture; Need not order a reversing shaft again when the adjustment pump turns to, cost is low, the cycle is short, replacing, easy for installation.
