Maintenance reminding method of central flue cleaning system

Abstract

The invention discloses a maintenance reminding method of a central flue cleaning system. The central flue cleaning system comprises extractor hoods installed at different floors, wherein an air outlet of each extractor hood communicates with a public use flue through flue pipelines; adjustable check valves are arranged on the flue pipelines; a flue main fan is arranged in the public use flue andcomprises an impeller; a concentrate filter is arranged in the public use flue; and flue main fan comes with a current detection module or a power detection module. According to the maintenance reminding method of the central flue cleaning system, whether the concentrate filter in the public use flue needs to be maintained or not can be determined by utilizing resistance coefficient detection principle according to before-and-after compassion of power of the flue main fan; in addition, whether the impeller of the flue main fan needs to be maintained or not can be determined according to the before-and-after compassion of the startup acceleration time of the flue main fan; and therefore, a more reasonable proactive maintenance service is provided for extraction systems of all users in a building, and the central flue cleaning system can always maintain a better working state.

Description

technical field [0001] The invention relates to a central purification system, in particular to a maintenance reminder method for the central flue purification system. Background technique [0002] In recent years, the user-side adjustable angle valve combined with the centralized filtration and discharge of the main fan at the flue outlet on the roof has begun to be used in some well-decorated buildings. The main fan on the roof, that is, the central range hood, performs frequency conversion + valve preset for users with different operating rates. The flow distribution is achieved at an angle, which can solve the poor smoke exhaust situation of the bottom user to a certain extent, and at the same time effectively control the flow rate and noise of the entire flue system. In addition, in order to purify the oil fume entering the public flue, a centralized flue filter is generally installed in the public flue. Effective purification. After the flue system has been used for ...

AI Technical Summary

Problems solved by technology

After the flue system has been used for a long time, the centralized filter of the flue will be clogged and its performance will be reduced, which will lead to an increase in system resistance and seriously affect the user's smoke exhaust, so it needs to be replaced in time

At present, people generally judge whether the centralized filter needs to be cleaned or replaced according to the service life or experience, but this maintenance method often cannot truly reflect the use of the centralized filter, and the filter may be replaced too early or too late

In addition, after the central flue system works for a long time, the air volume of the flue motor will decrease at the same speed, and the power will also change greatly, and the accumulation of impeller oil will make the start-up time longer. The impeller of the road main fan is maintained. Similarly, the existing flue system cannot provide intelligent reminders for the maintenance of the impeller, and it is prone to inappropriate maintenance timing.
