Abstract
The utility model discloses a antifriction plate adjusting device before open impeller of centrifugal pump comprises adjusting bolt, adjusting nut, preceding antifriction plate, impeller. A front wear-resistant plate is arranged between the pump body and the impeller and is fixed on the pump body by 3 groups of uniformly distributed adjusting bolts and adjusting nuts; a rear wear-resisting plate is arranged between the impeller and the pump cover and is fixed on the pump cover by an inner hexagonal screw. The utility model discloses mainly through adjusting bolt's rotation, because of its one side laminating on the pump body, clearance between antifriction plate and the impeller can change the centrifugal pump performance before can adjusting through the relative motion with the pump body. The utility model discloses simple structure, convenient operation need not tear open the pump and can adjust the equipment performance with the cutting impeller, practices thrift installation, debugging time cost.
Description
Technical Field
The utility model relates to an antifriction plate adjusting device before open impeller of centrifugal pump especially relates to the open impeller centrifugal pump when carrying the medium that has particulate matter, viscosity are big.
Background
The existing open impeller centrifugal pump is provided with a front wear-resistant plate between a pump body and an impeller, so that the pump cost is reduced, and the pump is convenient to process and replace. The size of the gap between the impeller and the front wear plate directly affects the performance and the use effect of the pump. On the premise of meeting the working condition, the smaller the clearance is, the higher the pump efficiency is, and therefore, the smaller the clearance is, the better the pump efficiency is. The existing gap adjusting method is mainly realized by fixing a front wear-resisting plate and adjusting an impeller; or the position of the front wear-resisting plate is adjusted, but the method mostly adopts a structure with separated adjustment and fixation or more complicated parts, and does not realize a better design scheme.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing an antifriction plate adjusting device before centrifugal pump's open impeller. The utility model discloses a solve the technical scheme that the problem that the aforesaid provided was taken is: an open impeller front wear plate adjusting device of a centrifugal pump comprises a pump body 1, a front wear plate 2, an impeller 3, a rear wear plate 4, a pump cover 5, an adjusting nut 6, an adjusting bolt 7 and an O-shaped sealing ring 8, and is characterized in that the front wear plate 2 is arranged between the pump body 1 and the impeller 3, and 3 groups of the adjusting bolts 7 and the adjusting nuts 6 are uniformly distributed on the pump body 1; a rear wear-resistant plate 4 is arranged between the impeller 3 and the pump cover 5 and is fixed on the pump cover by an inner hexagonal screw; an O-shaped sealing ring 8 is arranged between the inner side of the pump body 1 and the adjusting bolt 7.
The utility model discloses simple structure, convenient operation need not tear open the pump and can adjust the equipment performance with the cutting impeller, practices thrift installation, debugging time cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the adjusting bolt 7.
Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in fig. 1, the wear-resisting plate adjusting device before centrifugal pump's open impeller of the embodiment of the utility model discloses a wear-resisting plate adjusting device comprises pump body 1, preceding wear-resisting plate 2, impeller 3, back wear-resisting plate 4, pump cover 5, adjusting nut 6, adjusting bolt 7, O type sealing washer 8. A front wear-resistant plate 2 is arranged between the pump body 1 and the impeller 3, and is fixed on the pump body 1 by 3 groups of uniformly distributed adjusting bolts 7 and adjusting nuts 6; a rear wear-resistant plate 4 is arranged between the impeller 3 and the pump cover 5 and is fixed on the pump cover by an inner hexagonal screw; an O-shaped sealing ring 8 is arranged between the inner side of the pump body 1 and the adjusting bolt 7. In specific implementation, the adjusting bolt 7 is rotated clockwise, so that the gap between the impeller 3 and the front wear-resisting plate 2 is reduced; the adjusting bolt is rotated anticlockwise to increase the gap between the impeller 3 and the front wear plate 2. After the adjustment is finished, the adjusting nut 6 is screwed down, so that the O-shaped sealing ring 8 seals the pump body 1 and the adjusting bolt 7, and the front wear-resisting plate 2 is fixed on the pump body. Therefore, the utility model discloses simple structure, convenient operation practices thrift installation, debugging time cost.
