Embodiment 1

[0027] The cooling and heat preservation assembly 3 is divided into a cooling and heat preservation inner chamber 305 and a drainage inner chamber 306 by a partition assembly 303 , and a plurality of first drainage holes 301 and second drainage holes 307 are evenly arranged in a ring in the drainage inner chamber 306 .

[0028] The above-mentioned technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0029] Since the cooling and heat preservation assembly is separated into a cooling and heat preservation inner cavity and a drainage inner cavity by a partition plate assembly, and a number of first drainage holes and second drainage holes are uniformly arranged in a circular shape in the cooling and heat preservation inner cavity, the problem is effectively solved. In the prior art, the pipe is welded in the cooling and heat preservation assembly. Due to the limited position reserved in the cooling and hea...

Embodiment 2

[0031] The inner wall of the cooling and heat preservation assembly 3 is provided with an annular boss 302 , and the outer ring of the annular boss 302 is welded with a partition assembly 303 .

[0032] The above-mentioned technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0033] Since the inner wall of the cooling and heat preservation assembly is equipped with an annular boss, the outer ring of the boss is welded with a partition assembly, and the cooling and heat preservation assembly is divided into a cooling and heat preservation inner cavity and a drainage inner cavity through the partition plate assembly, so it is effectively solved. In the prior art, the technical problem of heat preservation of the easily crystallized medium cannot be realized, and then realized that the high-temperature magnetic pump can be cooled or kept warm according to the different media, the water inlet of the high-tem...

Abstract

The invention discloses a cooling and heat preservation assembly for a high-temperature magnetic drive pump. The cooling and heat preservation assembly comprises a cooling and heat preservation assembly body, the interior of the cooling and heat preservation assembly body is divided into a cooling and heat preservation inner cavity and a drainage inner cavity through a partition plate assembly, and a plurality of first drainage holes and second drainage holes are annularly and uniformly formed in the cooling and heat preservation inner cavity. As the interior of the cooling and heat preservation assembly body is divided into the cooling and heat preservation inner cavity and the drainage inner cavity through the partition plate assembly, and the multiple first drainage holes and the second drainage holes are annularly and uniformly formed in the cooling and heat preservation inner cavity, so that the problem that in the prior art, a pipe is welded in a cooling and heat preservation assembly body, due to the fact that the reserved position in the cooling and heat preservation assembly body is limited, the pipe can only be obliquely welded in a cooling hole in the cooling and heat preservation assembly body, and welding is not firm are solved, then a drainage loop is formed between a water inlet section and the first drainage holes, the drainage inner cavity and the second drainage holes from left to right without welding the pipe, and the drainage effect is achieved.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a cooling and heat preservation assembly for a high-temperature magnetic pump. Background technique [0002] The magnetic pump is composed of three parts: pump, magnetic driver and motor. The key component of the magnetic driver is composed of outer magnetic rotor, inner magnetic rotor and non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air. Gap and non-magnetic substances drive the inner magnetic rotor connected to the impeller to rotate synchronously, realize the non-contact transmission of power, and convert the dynamic seal into a static seal. [0003] The currently used magnetic pump has certain defects, such as the lack of convenient cooling and heat preservation functions, which makes the main body of the magnetic pump vulnerable to damage, thereby reducing the practicability of the magnetic pump. ...
