Abstract
The utility model relates to the accessory of a water pump, in particular to an anti-lock water pump impeller which is characterized in that an anti-corrosive layer is arranged outside the opening ring of the water pump impeller. The anti-lock water pump impeller effectively ensures that the clearance between the opening ring of the water pump impeller and a sealing ring is not changed for a long term, prevents the phenomenon that a motor is burned due to the locked rotor, and guarantees the performance of a liquor pump.
Description
Technical field
The utility model relates to the accessory of liquid pump, specifically a kind of anti-locking water pump vane.
Background technique
We know; existing 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 liquid 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 anti-locking 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 anti-locking water pump vane is characterized in that the choma of anti-locking water pump vane is provided with corrosion-resistant coating outward.
Corrosion-resistant coating can adopt stainless steel material to make in the utility model, 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-resistant coating 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 anti-locking water pump vane, for a long time, guaranteed that effectively the gap between anti-locking water pump vane choma and the seal ring is constant, avoid the locking rotor, burnt the generation of motor phenomenon, guaranteed the liquid pump performance.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, also is a kind of embodiment's structural representation.
Embodiment
Anti-as shown in drawings locking water pump vane, be provided with water point impeller 1, the choma that it is characterized in that anti-locking 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-resistant coating 2 with anti-locking water pump vane 1, the utility model can be long-term, guaranteed that effectively the gap between anti-locking water pump vane choma and the seal ring is constant, avoided the locking rotor, burn the motor phenomenon and take place, guaranteed the liquid pump performance.
