Abstract
The utility model discloses a slurry pump comprising a rotating shaft and an impeller cavity which is formed by a rear protection plate and a protection bush. The slurry pump is characterized in that the connection surfaces of the rear protection plate (1) and the protection bush (2) are respectively an outer cylinder surface and an inner cylinder surface. The rear protection plate (1) and the protection bush (2) are connected by a connection device through the matching positioning of the outer cylinder surface and the inner cylinder surface and the impeller cavity is formed. Due to the fact that the outer cylinder surface and the inner cylinder surface are positioned in a matching mode, the matching surface is not only prone to be processed and detected, but also further in accordance with site using requirements. Therefore, whole service life of the slurry pump can be prolonged. Production efficiency is improved because the matching surface is convenient to measure.
Description
Technical field
The utility model relates to the slag stock pump, exactly relates to the fitting surface of backplate and sheath behind the slag stock pump.
Background technique
The slag stock pump belongs to a kind of of centrifugal pump from physics principle, refer in concept make by the effect by centrifugal force (rotation of the impeller of pump) a kind of machinery of solid, liquid mixed medium energy increase, convert electric energy to the kinetic energy of medium and the equipment of potential energy.The slag stock pump comprises impeller cavity and is positioned at the impeller of impeller cavity that impeller cavity is connected and composed by rear backplate and sheath.Cooperating between the present slag stock pump industry, rear backplate and sheath is that the inclined-plane cooperates, and the purpose of doing like this is to be convenient to Assembly And Disassembly.The purpose of inclined-plane matching design is in order to assemble and convenient disassembly, but because machining accuracy is inadequate, the inclined-plane of rear backplate and the inclined-plane of sheath when cooperating, present interior triangle or outside triangle, always there is the gap during cooperation, because the existence in gap, pump always is worn first at gap location when operation, has reduced the working life of pump; On the other hand, owing to be that the inclined-plane also is difficult to Measurement accuracy, reduced manufacturing efficiency.
The model utility content
Backplate cooperated with the sheath inclined-plane after the purpose of this utility model solved the slurry pump impeller chamber exactly, and gap location easily is worn, and reduced pump working life; The inclined-plane is difficult to measure, and reduces the problem of manufacturing efficiency.
The technical solution adopted in the utility model is: a kind of slag stock pump, it comprises rotating shaft and the impeller cavity that is connected and composed by rear backplate and sheath, the junction surface that it is characterized in that described rear backplate and sheath is respectively external cylindrical surface and inner cylindrical surface, and rear backplate connects and composes impeller cavity with the location that cooperates of inner cylindrical surface by connection set by external cylindrical surface with sheath.
Be provided with seal ring between described rear backplate and the sheath surface of contact and realize liquid sealing.
The utility model beneficial effect is: because rear backplate is that external cylindrical surface cooperates the location not only to make fitting surface be easy to processing and detection with inner cylindrical surface with sheath, more meet simultaneously on-the-spot usage requirement, the whole service life of pump is prolonged, owing to be convenient to measure fitting surface, improved manufacturing efficiency.
Description of drawings
Fig. 1 is the utility model schematic representation.
Embodiment
As shown in Figure 1, present embodiment comprises rotating shaft and the impeller cavity that is connected and composed by rear backplate and sheath, rotating shaft is movably connected on the carriage, rear backplate 1 is respectively external cylindrical surface and inner cylindrical surface with the junction surface of sheath 2, and rear backplate 1 connects and composes impeller cavity with the location that cooperates of inner cylindrical surface by connection set by external cylindrical surface with sheath 2.Be provided with seal ring between rear backplate 1 and sheath 2 surface of contact and realize liquid sealing.
Claims (2)
1. slag stock pump, it comprises rotating shaft and the impeller cavity that is connected and composed by rear backplate and sheath, it is characterized in that described rear backplate (1) and the junction surface of sheath (2) are respectively external cylindrical surface and inner cylindrical surface, rear backplate (1) connects and composes impeller cavity with the location that cooperates of inner cylindrical surface by connection set by external cylindrical surface with sheath (2).
2. a kind of slag stock pump according to claim 1 is characterized in that being provided with between described rear backplate (1) and sheath (2) surface of contact seal ring and realizes liquid sealing.
