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
The present invention relates to chemical industry, the application of particularly a kind of deionized water in chemical pump machine envelope cools.
Background technique
In order to prevent that chemical liquid from leaking outside in course of conveying; Chemical pump generally needs double-sealing, and centrifugal pump drives sealing Moving plate and quiet dish sliding friction (linear velocity that has is up to 30m/s) when running up, and produces big calorimetric; Must heat be taken out of through heat transfer medium, keep equipment stable operation.
Former use tap water is taken heat out of as heat transfer medium, can reach this purpose, still; Because the fricative relatively big calorimetric of machine envelope produces incrustation scale with calcium-magnesium ratio compound deposition in the tap water; Adhere to around the sealing, cause friction factor to increase, shortened sealing life.Simultaneously, if the machine envelope is revealed, the impurity in the tap water can pollute chemical industry liquid, causes the accident, and therefore, the processing of machine envelope cooling haves much room for improvement and innovates.
Summary of the invention
To above-mentioned situation, for overcoming the defective of existing technology, the object of the invention just provides the application of a kind of deionized water in chemical pump machine envelope cools, and can effectively solve the problem that chemical pump machine envelope cools.
The technological scheme that the present invention solves is; To take heat with tap water out of as heat transfer medium originally; Realization cools to chemical pump machine envelope, replaces tap water with deionized water, takes heat out of as heat transfer medium at present; Realization cools to chemical pump machine envelope, thereby realizes the application of deionized water in chemical pump machine envelope cools.
The machine envelope life-span of the present invention is long, and equipment loss is low, has avoided equipment accident, has improved economic benefit.
Embodiment
Below in conjunction with reality, specific embodiments of the invention elaborates.
The present invention under the sealing Moving plate and quiet dish sliding friction linear velocity 30m/s state with chemical pump, adopts deionized water as heat transfer medium chemical pump machine envelope to be cooled in practical implementation at present; Effect is very good; Guaranteed that effectively machine seals the good user mode and the using effect of chemical pump, and avoided the generation of accident, through test; And with existing technology contrast, the result is following:
| ? | The machine envelope life-span | Laggard water-exit temperature was poor in 3 months | The leakage causality loss | The cost of water own |
| Tap water | 65 days | 2℃kg/min | 3000 yuan/half a year | 30 yuan/half a year |
| Deionized water | 150 days | 1.2℃kg/min | 0 | 70 yuan/half a year |
Can find out by above-mentioned, after the chemical pump machine seals the water use deionized water that cools, though the water cost increases by 40 yuan/half a year; But avoided 3000 yuan/half a year of causality loss; And the machine envelope prolonged 85 days in the life-span, is more than the original twice, improved economic benefit greatly; Getting well of its effect formerly do not expected, was the innovation that chemical pump machine envelope cools.
