Abstract
The utility model discloses a centrifugal pump with high temperature resistance and corrosion resistance. A motor is arranged on a bracket; a rotating shaft of the motor rotates a graphite transmission shaft downward by a transmission shaft; the lower end of the graphite transmission shaft is connected with a graphite impeller in a graphite pump shell; the graphite impeller is provided with drainage holes which are distributed radially; the bottom part of the graphite impeller is provided with suction holes; and a vortex flow channel of the graphite pump shell and a graphite drain pipe are communicated. The centrifugal pump not only has corrosion resistance, high temperature resistance and long service life, but also has simple structure, easy manufacture, low cost, convenient replacement of graphite members, and convenient installation, use and maintenance of the system, has no pollution to metal melt, can guarantee the purity of the conveyed metal and can be widely used for the conveying of corrosive metal melt.
Description
Technical field
The utility model relates to a kind of centrifugal pump, particularly relates to a kind of centrifugal pump that metal bath is carried that is used for.
Background technique
At present, have minority producer to release to adopt the pump that metal bath is carried that is used for of alloy material manufacturing, its price is expensive, and alloy also in use progressively dissolved, and causes metal ingredient to pollute.Owing to these reasons, such pump is not used widely.
Also there are methods such as the surface of employing sprays, inserts that the graphite part is used in the pump product, the parts of surface graphite spraying are fixed on other structure, to play corrosion resistant effect, this mode still can only be used for the not high medium transport of temperature, carry and can not be used for metal bath, and graphite material comes off easily.
For above-mentioned reasons, runner type is still adopted in the conveying of present domestic corrosion metals melt, and this mode exists the setup time of releasing long, and the chute thermal loss is big, and burning is serious, defective such as cost of production height, efficient are low.
The model utility content
The utility model will solve existing centrifugal pump and be difficult to corrosion-and high-temp-resistant, be not useable for the problem that the corrosivity high-temperature fusant is carried, provide a kind of and have good corrosion-resistant, resistance to high temperature, and the centrifugal pump that is used for the metal bath conveying simple in structure, that be easy to make.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: on a support motor is installed, machine shaft rotates the graphite transmission shaft by transmission shaft downwards, and graphite transmission shaft lower end connects the graphite impeller in the graphite pump housing; The outage that radial arrangement is arranged in the graphite impeller, imbibing hole is arranged at the graphite impeller bottom; The vortex runner of graphite pump housing communicates with the graphite drain pipe.
In the utility model, graphite impeller adopts the straight hole impeller, promptly establishes a plurality of straight hole passages in the graphite disk body of impeller as outage, and the imbibing hole of outage and impeller constitutes fluid passage.When adopting the machining graphite impeller, the manufacturing of being more convenient for of straight hole impeller, and more durable.
During use, graphite transmission shaft lower end and the graphite impeller that is attached thereto, graphite pump housing and graphite drain pipe lower end are stretched in the high temperature corrosion liquid, starting electrical machinery is realized the conveying from the bottom to top of high temperature corrosion liquid.
Centrifugal pump of the present utility model is not only corrosion-resistant, high temperature resistant, long service life, and also pump body structure is simple, easily makes, cost is low, and graphite component is changed convenient, system's installation, use, easy to maintenance; Pollution-free to metal bath, can guarantee the purity of transferring metal; The utility model can be widely used in the conveying of corrosion metals, improves its transfer efficiency, reduces its energy loss and lowers oxidation.
