Heat insulation magnetic force pump with flow passage components wrapped totally

Abstract

The invention provides a heat insulation magnetic force pump with flow passage components wrapped totally. The heat insulation magnetic force pump comprises a pump body, an impeller, an intermediate bearing body, a pump shaft, a thrust disk assembly, a shaft sleeve, a retaining sleeve, a bearing sleeve, an internal magnet rotor assembly, a spacer sleeve, an external magnet rotor assembly and a connecting frame. The periphery of the pump body is wrapped by a front heat insulation cavity formed by a metal jacket. The periphery of the intermediate bearing body is wrapped by an intermediate heat insulation cavity formed by a metal jacket. A circulating pipe is arranged on the intermediate bearing body. The circulating pipe penetrates through the intermediate heat insulation cavity to reach aninner cavity of an inner spacer sleeve body. The spacer sleeve comprises the inner spacer sleeve body and an outer spacer sleeve body. A flange ring is arranged between the inner spacer sleeve body and the outer spacer sleeve body. A rear heat insulation cavity is defined by the inner spacer sleeve body, the flange ring and the outer spacer sleeve body. The heat insulation magnetic force pump hasthe advantages of being sufficient in heat insulation, safe, reliable and good in circulation effect.

Description

technical field [0001] The invention relates to a pump, in particular to a thermal insulation magnetic pump with flow-passing parts fully covered. Background technique [0002] At present, magnetic pumps are completely leak-free, and are widely used in the transportation of various flammable, explosive, toxic, harmful, and valuable liquid media. The magnetic pump has high requirements on the purity of the liquid medium to be transported. The magnetic pump transports the medium that is easy to crystallize. The crystallization will cause damage to the internal parts of the magnetic pump, and even the pump cannot be started. The thermal insulation magnetic pump is a derivative product of the magnetic pump designed and developed for the easy-to-crystallize medium and temperature-sensitive medium. Steam or heat transfer oil, etc. exchange energy with the medium in the pump to achieve the purpose of heat preservation. However, the inner cavity of the insulating sleeve of the heat...

Problems solved by technology

The magnetic pump has high requirements on the purity of the liquid medium to be transported. The magnetic pump transports the medium that is easy to crystallize, and the crystallization will cause damage to the internal parts of the magnetic pump, and even the pump cannot be started.

The thermal insulation magnetic pump is a derivative product of the magnetic pump designed and developed for the easy-to-crystallize medium and temperature-sensitive medium. Steam or heat transfer oil, etc. exchange energy with the medium in the pump to achieve the purpose of heat preservation. However, the inner cavity of the insulating sleeve of the heat-insulation magnetic pump cannot achieve heat preservation by covering the jacket. The current method is to advance the jacket of the pump body and the intermediate bearing body Put in the medium used for heat preservation and keep it for a long time, and then check whether the medium in the pump is fully preheated after turning the pump manually, so as to judge whether the heat preservation magnetic pump can be started. The outlet is designed in a horizontal direction, and the parts in the lower position are often unable to be fully preheated due to the condensed water generated after the heat preservation steam condenses, which greatly reduces the heat preservation effect
