答：想判斷羅茨風機的轉向，其實很簡單的。因為一般羅茨風機機體上都有轉向標識，從而可以確定電機轉向(這里強調的是需要注意主動葉輪軸與電機軸連接方式);如果羅茨風機機體上轉向標識沒有，可以這樣確定，以二葉羅茨風機為例，首先確定通過羅茨風機出口端儲氣罐及入口端空氣濾清器來確定羅茨風機進風口，根據羅茨風機工作原理，從進風口側看入口端兩個葉輪轉向都是朝兩側殼體方向轉動(這與齒輪油泵工作原理相同)，這樣可確定主動葉輪旋轉方向，從而也就確定了電機轉向。

　　注意事項與前面括號內所述內容相同。

　　三葉羅茨風機電機旋轉方向確定方法與上述基本相同。羅茨風機機體主動端葉輪轉向，一般羅茨風機機體上都有轉向標識，從而可以確定電機轉向(這里強調的是需要注意主動葉輪軸與電機軸連接方式);如果羅茨風機機體上轉向標識沒有，可以這樣確定，以二葉羅茨風機為例，首先確定通過羅茨風機出口端儲氣罐及入口端空氣濾清器來確定羅茨風機進風口，根據羅茨風機工作原理，從進風口側看入口端兩個葉輪轉向都是朝兩側殼體方向轉動(這與齒輪油泵工作原理相同)，這樣可確定主動葉輪旋轉方向，從而也就確定了電機轉向，注意事項與前面括號內所述內容相同。

　　至于其他的密集式羅茨風機、沉水式羅茨鼓風機、魯氏羅茨風機、龍鐵羅茨風機、章丘羅茨鼓風機、真空式羅茨鼓風機等!都會在羅茨風機機頭標注葉輪轉向!細心觀察機殼紋路，即可斷定葉輪轉向!

　　It is very simple to judge the rotation direction of Roots blower. Generally, there is a steering mark on the roots blower body, so the motor steering can be determined (it is emphasized here that attention should be paid to the connection mode between the driving impeller shaft and the motor shaft); If there is no steering mark on the roots blower body, it can be determined in this way. Take the two blade roots blower as an example. First, determine the air inlet of the roots blower through the air storage tank at the outlet and the air filter at the inlet. According to the working principle of the roots blower, the two impellers at the inlet turn towards the shells on both sides from the air inlet side (the same working principle as the gear oil pump), so as to determine the rotation direction of the driving impeller, Thus, the motor steering is determined.

　　The precautions are the same as those in the brackets above.

　　The method for determining the rotation direction of three blade roots blower motor is basically the same as the above. The rotation direction of the impeller at the active end of the roots blower body is generally marked on the roots blower body, so that the rotation direction of the motor can be determined (it is emphasized here that attention should be paid to the connection mode between the active impeller shaft and the motor shaft); If there is no steering mark on the roots blower body, it can be determined in this way. Take the two blade roots blower as an example. First, determine the air inlet of the roots blower through the air storage tank at the outlet and the air filter at the inlet. According to the working principle of the roots blower, the two impellers at the inlet turn towards the shells on both sides from the air inlet side (the same working principle as the gear oil pump), so as to determine the rotation direction of the driving impeller, Thus, the rotation direction of the motor is determined. The precautions are the same as those described in the brackets above.

　　As for other intensive roots blower, submerged roots blower, Lushi roots blower, Longtie roots blower, Zhangqiu roots blower, vacuum roots blower, etc! The impeller direction will be marked on the head of Roots blower! Carefully observe the casing lines to determine the impeller rotation!
