Method for determining and testing maintenance period of hood impeller

Abstract

The invention relates to a method for determining and testing a maintenance period of a hood impeller. The method is characterized by comprising the steps that 1, a cleaning threshold value is determined; 2, mixed oil circuit accelerated tests are performed, wherein test oil and test water are added into a test pot to generate lampblack, the test number and the weight gain conditions of the impeller are recorded; 3, the acceleration multiple is calculated, and the weight gain value of the impeller after each mixed oil circuit accelerated test is calculated according to the test number and theweight gain conditions of the impeller; 4, data corresponding to each maintenance period is calculated, and the weight gain value of the impeller in each period is calculated according to the acceleration multiple and the weight gain value of the impeller after a cooker hood is used in each period; then the maintenance period of the impeller of a to-be-detected cooker hood is judged according to the weight gain value of the impeller in each period. The method for determining and testing the maintenance period of the hood impeller has the advantages that the operation is simple and efficient, the time is short, and the consistency is high.

Description

technical field [0001] The invention relates to maintenance of an impeller of a range hood, in particular to a method for determining the maintenance cycle. Background technique [0002] After the range hood impeller is used for a certain period of time, the oil on the impeller will accumulate different grease weights with the length of use. The accumulation of grease weight to a certain extent will have a certain impact on the performance of the range hood (including air volume, noise, etc.) and the life of the motor. Therefore, it is necessary to determine the maintenance period of the impeller, so as to facilitate regular maintenance and cleaning, and ensure its long-term and effective service. Different models of impellers have different maintenance periods, which need to be determined by methods. [0003] If the maintenance period is counted according to normal use, there is a shortcoming of a long cycle, which can be as short as two years and as long as five years. I...

[0003] If the maintenance period is counted according to normal use, there is a shortcoming of a long cycle, which can be as short as two years and as long as five years. If the maintenance period is counted through laboratory tests, although the desired maintenance period can be obtained in a short time data, but it is difficult to guarantee the accuracy and scientificity of the results, so it must be combined with practical application

[0004] So far, researchers in this field have not published information on how to scientifically obtain the maintenance period of the impeller through limited experiments.
