Cause of Disallowed Gas Concentration in Flow-separation Chamber of Exhaust Coatra-rotary Fan and Its Solution |
| |
| Abstract: | To counter the existence of unsafe hidden peril due to disallowed gas concentration in the cooling air in flow separation chamber of Class Ⅱ electrical motor during the operation of flame-proof mine contra-rotary exhaust fan in our country,the paper describes an effective negative-pressure flow-separation chamber for solving this problem and discusses the structural features,working principle,design computation and application effect of this chamber.Experiments showed that the use of negative-pressure chamber can effectively control the gas-containet air flow in the main air channel entering the flow separation chamber of Class Ⅱ elecric motor. |
