Description
Technical Field
The invention relates to a magnetic pump, in particular to a magnetic pump with integral external heat insulation.
Background
The magnetic pump is a common fluid conveying machine, and is widely applied to the industries of medicine, chemical industry, bathroom and the like due to the advantages of no leakage, low noise, stable operation and the like. The magnetic pump comprises a shell, an impeller, a pump cover, a pump shaft, an inner magnetic rotor, an isolation sleeve, an outer magnetic rotor, a motor and a lining plate positioned at the end part of the motor, wherein the outer magnetic rotor is fixedly connected with the motor shaft, the inner magnetic rotor is fixedly connected with the pump shaft, the isolation sleeve consists of a flange, a thin-walled cylinder and a bottom plate, the flange of the isolation sleeve is connected with the pump cover, the motor drives the outer magnetic rotor to rotate and then drives the inner magnetic rotor to rotate, and the inner magnetic rotor is a driven part. The magnetic pump conveys easily crystallized medium, and casing, pump cover, interior magnetic rotor department easily crystallize the medium and solidify easily and become likepowder, cubic, and the resistance is big, can lead to the bearing to damage, can't start even, and the easily crystallized medium of casing and pump cover department melts easily, but the easy crystallized medium of interior magnetic rotor department can't melt because the heat source can't reach this region, leads to being difficult to shut down at any time and start, has increased user use cost.
Disclosure of Invention
The invention aims to provide a magnetic pump with integral external heat insulation for preventing medium from being condensed.
The technical scheme adopted by the invention is as follows:
a magnetic pump with integral external heat preservation comprises a pump shell, wherein a rotating shaft support is arranged in the pump shell, the rotating shaft is connected to the rotating shaft support in a penetrating mode, the rotating shaft support divides an inner cavity of the pump shell into a working cavity and a power cavity, an inner rotor is arranged in the power cavity and fixedly installed at one end of the rotating shaft, an impeller is arranged in the working cavity, the other end of the rotating shaft is installed with the impeller, a feed inlet is formed in a cavity above the impeller, a discharge outlet is formed in a cavity on the left side of the impeller, a heat preservation jacket covering the working cavity is arranged on the outer side of the pump shell, and a connecting flange communicated; the pump cover is arranged on the right side of the power cavity and is installed on the pump shell through screws, an outer rotor matched with the inner rotor is arranged in the power cavity and is connected with a power source outside the pump shell, an isolation sleeve is arranged between the inner rotor and the outer rotor, the installation end of the isolation sleeve is fixed between the pump shell and the pump cover, the isolation sleeve and the pump cover form a sealed cavity in a surrounding mode, and the outer rotor is located in the sealed cavity; the heat preservation device is characterized in that a closed heat preservation cavity is formed between the rotating shaft support and the inner wall of the pump shell in a surrounding mode, the heat preservation cavity covers the power cavity and the rotating shaft, and a connecting flange communicated with the heat preservation cavity is arranged on the pump shell.
After the technical scheme is adopted, the invention has the beneficial effects that: the traditional magnetic pump only preserves the heat of the impeller, the inlet and the outlet of the working cavity and neglects the heat preservation of the power cavity. In the technical scheme, except for heat preservation of the working cavity, the inlet and the outlet in the prior art, a heat preservation cavity is formed between the rotating shaft bracket and the inner wall of the pump shell and covers the whole power cavity and the rotating shaft, so that the influence on the magnetic pump after the medium entering the power cavity is condensed is avoided; the inner rotor and the outer rotor of the magnetic pump are isolated by the isolating sleeve, so that the outer rotor is prevented from being polluted.
