Heat insulation shell for high-temperature pump

Abstract

The invention discloses a heat insulation shell for a high-temperature pump. The heat insulation shell comprises a tubular shell body, and the peripheral wall of the shell body is provided with a motor supporting platform and a fixed platform from top to bottom. The heat insulation shell further comprises a cooling liquid passage and an enclosure, the enclosure is a wall surface with the lower endconnected to the shell body and stretching out of the shell body, the fixed platform is arranged at the upper end of the enclosure, and an air-cooled heat insulation cavity with a sealed lower end and an open upper end is formed between the enclosure and the peripheral wall surface of the shell body. The cooling liquid passage is formed in the shell body and is opposite to the enclosure. Under the dimensional space limitation condition, the heat insulation shell is additionally provided with the air-cooled heat insulation cavity and the cooling liquid passage through structure optimization, two-stage stepped heat dissipation is realized, and the heat transferred to a motor can be greatly reduced. Meanwhile, the two-stage stepped heat dissipation structure can not only reduce the ultra-high heat stress caused by rapid cooling of liquid, but also reduce the consumption of cooling liquid, so that the service life of the motor and the whole pump is prolonged.

Description

technical field [0001] The invention belongs to the technical field of non-variable pumps, and in particular relates to a heat-insulating casing for a high-temperature pump. Background technique [0002] Such as figure 1 As shown, in the existing special high-temperature pump, the shaft 1 is driven by the motor 3 connected to the casing 2, because the casing 2 needs to be connected to the high-temperature container 4 to transport the high-temperature medium, and due to the special high-temperature working conditions and the limited space The restriction makes it easy for the heat to be transferred to the motor 3 through the casing 2, thereby affecting the service life of the motor and the whole pump. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a heat-insulating casing for a high-temperature pump, which can eliminate the heat transfer problem existing in the application ...
