Abstract
The utility model discloses a wear resisting centrifugal water pump, which is suitable for slurry pumping operation in the ore dressing industry, or other similar environments and prolongs the service life of the pump and reduces manufacture cost. The utility model has the technical proposal that the inner wall of a pump cover 4 in an impeller cavity 3 and the inner wall of a pipe of a water inlet 1 and a water outlet 2 are respectively and fixedly connected with a layer of silicon carbide protecting sleeve 5. A ceramic adhesive layer is arranged between the silicon carbide protective sleeve 5 and the inner wall of the pump cover.
Description
Technical field:
The utility model relates to a kind of centrifugal water pump, particularly a kind of centrifugal quarrel stock pump or slurry pump commonly used in mining processing industry.
Background technique:
In mining processing industry, often use centrifugal quarrel stock pump and slurry pump to take out ore pulp.Because pulp concentration is bigger, and contain a lot of impurity, and produce enough lift and flow process in order to make pump, must make pump have enough centrifugal force, yet one to come ore pulp, mortar will be very big also to the wearing and tearing that the pump cover internal layer produces thus, and general about one month will be worn out the pump cover backplate.
Summary of the invention:
The purpose of this utility model is to provide a kind of wear-resisting formula centrifugal water pump, to adapt to the slurry work of taking out in mining processing industry or in other like environment, prolongs its working life, reduces production costs.
The purpose of this utility model realizes by implementing following technical proposals:
A kind of wear-resisting formula centrifugal water pump comprises water intake, water outlet, impeller cavity, pump cover, it is characterized in that: be connected with the wear-resisting sheath of one deck on the pump cover inwall in impeller cavity.
Between wear-resisting sheath of the utility model and pump cover inwall layer of adhesive is arranged.
The wear-resisting sheath of the utility model is that silicon carbide is made, and tackiness agent is a ceramic binder.
Be connected with one deck silicon carbide sheath on the inner tube wall of the utility model water intake, water outlet.
The utility model has improved the wear-resisting property of centrifugal water pump pump cover inwall significantly by at pump cover inwall and turnover water pipe inwall place the silicon carbide sheath being set, and has prolonged working life; And the raw material that adopted are cheap and silicon carbide that wear-resisting property is very superior causes processing cost to reduce greatly, and durable in use.
Description of drawings: Fig. 1 is the utility model cross-sectional view
Embodiment:
A kind of wear-resisting formula centrifugal water pump comprises water intake 1, water outlet 2, impeller cavity 3, pump cover 4, on pump cover 4 inwalls in impeller cavity 3, and is connected with one deck silicon carbide sheath 5 on the inner tube wall of water intake 1, water outlet 2.Between this silicon carbide sheath 5 and pump cover inwall one deck ceramic binder is arranged.
