Problems solved by technology

[0003] The original use of tap water as the heat transfer medium to bring out the heat can achieve this purpose. However, due to the large amount of heat generated by the relative friction of the mechanical seal, the calcium and magnesium compounds in the tap water will deposit and produce scale, which will adhere to the surrounding of the seal, resulting in an increase in the friction coefficient and making the seal shortened lifespan
At the same time, if the mechanical seal leaks, the impurities in the tap water will contaminate the chemical liquid and cause accidents. Therefore, the cooling treatment of the mechanical seal needs to be improved and innovated

Embodiment Construction

[0007] The specific implementation of the present invention will be described in detail below in combination with practice.

[0008] In the specific implementation of the present invention, under the state of the sliding friction line speed of the sealed movable disk and the static disk of the chemical pump is 30m / s, deionized water is now used as the heat transfer medium to cool the mechanical seal of the chemical pump, and the application effect is very good, effective It ensures the good use state of the mechanical seal and the use effect of the chemical pump, and avoids the occurrence of accidents. After testing and comparing with the existing technology, the results are as follows:

Abstract

The invention relates to an application of deionized water in cooling a chemical pump machine seal, and the deionized water can be used for cooling the chemical pump machine seal effectively. The technical scheme adopted by the invention is as follows: in the prior art, heat is taken away by tap water serving as a heat transfer medium so as to cool the chemical pump machine seal; and in the invention, the deionized water is used for replacing tap water to serve as a heat transfer medium for taking heat away so as to cool the chemical pump machine seal, thus the application of the deionized water in cooling the chemical pump machine seal is realized. According to the invention, the machine seal is long in service life, the equipment loss is low, the device accident is avoided, and the economic benefit is improved.

Description

technical field [0001] The invention relates to chemical industry, in particular to the application of deionized water in the cooling and cooling of chemical pump mechanical seals. Background technique [0002] In order to prevent the chemical liquid from leaking during the transportation process, chemical pumps generally need double seals, and when the centrifugal pump is running at high speed, it drives the sliding friction between the sealed moving plate and the static plate (some linear speeds are as high as 30m / s), generating a lot of heat, which must be passed The heat medium takes the heat out to keep the equipment running stably. [0003] Originally, tap water was used as the heat transfer medium to bring out the heat, which can achieve this purpose. However, due to the large amount of heat generated by the relative friction of the mechanical seal, the calcium and magnesium compounds in the tap water will deposit and produce scale, which will adhere to the surroundin...
