Abstract
The utility model discloses an impeller wear ring sealing structure, which comprises a pump body, impeller wear rings, an inlet wear ring, a pump body wear ring, a set screw and a water inlet section. The impeller wear rings are arranged on an impeller; the water inlet section and the pump body are respectively provided with the inlet wear ring and the pump body wear ring, and an elastic-plastic polymer composite material which is in contact with each impeller wear ring to form a friction surface is nested in each of the inlet wear ring and the pump body wear ring; and the inlet wear ring is provided with an arc-shaped spur matched with the arc line of a front cover plate of the impeller, and the fit clearance between the arc-shaped spur and the front pump cover plate of the impeller is 0.5 millimeter. The structure is unique, liquid leakage can be almost avoided at the wear rings of a water pump, the service life is effectively prolonged, the using cost is reduced, the sealing effect is good, and energy is saved.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to a kind of impeller port ring sealing configuration.
Background technique
Because the centrifugal action of water pump vane can form the height nip in pump chamber, the liquid of height nip can flow to low pressure area, and the flow region of this liquid promptly occurs in the impeller port ring place; In present water pump, what impeller port ring adopted is straight control ring seal, choma and Spielpassung, and the gap is big; Resistance is little, therefore exists leakage rate big, the problem of sealing effect difference; The flow and the lift that cause pump thus reduce, and it is many that prime mover is made idle work, and energy waste is big.
Summary of the invention
The purpose of the utility model is to overcome the deficiency in the problems referred to above, and a kind of impeller port ring sealing configuration is provided.
For solving the problems of the technologies described above, the technological scheme of the utility model is: a kind of impeller port ring sealing configuration, comprise the pump housing, and it also comprises impeller port ring, import choma, pump housing choma, Cock screw, inlet segment; Said impeller is provided with impeller port ring; Be respectively equipped with import choma and pump housing choma on the said inlet segment and the pump housing, import choma and pump housing choma are nested with and are useful on the bullet that forms rubbing surface that contacts with impeller port ring and mould polymer composites;
The import choma is provided with the arc spur that the front shroud camber line with impeller is complementary, and the matching gap of arc spur and impeller front pump cover plate arc plate is 0.5mm.
The utility model structure is unique, can make the choma place of water pump reach the effect that no liquid is almost leaked, and it is big fully to have solved water pump choma leakage rate, and the technical barrier that volumetric efficiency is low has guaranteed the volumetric efficiency of water pump to have improved total efficiency.Its unique mechanism make water pump impeller can not rub with the pump housing and inlet segment, thereby prolonged working life, reduced user cost, sealing effect has better been practiced thrift the energy.
Description of drawings
To combine accompanying drawing and embodiment below, the utility model will be further described.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the import choma structural representation of the utility model.
