[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, it can be seen that the cooling water of the chemical pump mechanical seal uses deionized water, although The cost of water increased by 40 yuan / half a year, but the accident loss of 3,000 yuan / half a year was avoided, and the life of the machine seal was extended by 85 days, which was more than twice the original, greatly...

The invention relates to the application of deionized water in the cooling and cooling of chemical pump seals, which can effectively solve the problem of cooling and cooling of chemical pump seals. Chemical pump mechanical seal cooling and cooling, deionized water is now used instead of tap water, as a heat transfer medium to bring out heat, to achieve cooling and cooling of chemical pump mechanical seals, thereby realizing the application of deionized water in chemical pump mechanical seal cooling and cooling, the present invention The mechanical seal has a long service life and low equipment loss, which avoids equipment accidents and improves economic benefits.
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 leakage of chemical liquid 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 through the transmission. 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 ...
