Abstract
The utility model relates to a water pump accessory, in particular relating to a water pump vane wheel. The utility model is characterized in that a corrosion protection layer is arranged outside the choma of the water pump vane wheel. The utility model has the advantages of ensuring the cap between the choma of the water pump vane wheel and the sealing ring constant, avoiding the situations of stator died and motor burned and ensuring the capability of the water pump.
Description
Affiliated technical field
The utility model relates to the accessory of water pump, specifically a kind of water pump vane.
Background technique
As everyone knows; water pump generally is made up of the pump housing, pump cover, impeller and seal ring etc.; existing water pump vane generally adopts the gray iron material casting after machining forms; adopt Spielpassung to seal between impeller port ring and the seal ring; because the easy corrosion of gray iron material; particularly when water pump is long-time shut down after, it is zero that the corrosion that the impeller port ring place produces makes the gap between itself and the seal ring, thereby causes the locking rotor, burn the motor phenomenon.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of water pump vane is provided, and it can prevent the locking rotor effectively, burn the generation of motor phenomenon.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of water pump vane, the choma that it is characterized in that water pump vane is provided with corrosion-resistant coating outward, this corrosion-resistant coating can adopt stainless steel material to make, also can adopt aluminum alloy, Cuprum alloy or plastics etc. to make, corrosion-resistant coating can adopt the bimetallic material casting after machining forms, after also can making water pump vane and corrosion-resistant coating respectively earlier, adopt method such as closely cooperate, bonding that corrosion protection is connected with the choma of water pump vane again.
The beneficial effects of the utility model are: owing to be provided with corrosion-resistant coating outside the choma of water pump vane, for a long time, guaranteed that effectively the gap between water pump vane choma and the seal ring is constant, avoid the locking rotor, burnt the generation of motor phenomenon, guaranteed the performance of water pump.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, also is a kind of embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings: a kind of water pump vane, be provided with water point impeller 1, the choma that it is characterized in that water pump vane 1 is provided with corrosion-resistant coating 2 outward, corrosion-resistant coating 2 can adopt stainless steel material to make, also can adopt aluminum alloy, Cuprum alloy or plastics etc. are made, corrosion-resistant coating 2 can adopt the bimetallic material casting after machining forms, after also can having made water pump vane 1 and corrosion-resistant coating 2 earlier respectively, adopt again and closely cooperate, method such as bonding is connected the choma of corrosion protection 2 with water pump vane 1, the utility model can be long-term, guaranteed that effectively the gap between water pump vane choma and the seal ring is constant, avoided the locking rotor, burn the motor phenomenon and take place, guaranteed the performance of water pump.
