答：想判断罗茨91视频下载免费的转向，其实很简单的。因为一般罗茨91视频下载免费机体上都有转向标识，从而可以确定电机转向(这里强调的是需要注意主动叶轮轴与电机轴连接方式);如果罗茨91视频下载免费机体上转向标识没有，可以这样确定，以二叶罗茨91视频下载免费为例，首先确定通过罗茨91视频下载免费出口端储气罐及入口端空气滤清器来确定罗茨91视频下载免费进风口，根据罗茨91视频下载免费工作原理，从进风口侧看入口端两个叶轮转向都是朝两侧壳体方向转动(这与齿轮油泵工作原理相同)，这样可确定主动叶轮旋转方向，从而也就确定了电机转向。

　　注意事项与前面括号内所述内容相同。

　　三叶罗茨91视频下载免费电机旋转方向确定方法与上述基本相同。罗茨91视频下载免费机体主动端叶轮转向，一般罗茨91视频下载免费机体上都有转向标识，从而可以确定电机转向(这里强调的是需要注意主动叶轮轴与电机轴连接方式);如果罗茨91视频下载免费机体上转向标识没有，可以这样确定，以二叶罗茨91视频下载免费为例，首先确定通过罗茨91视频下载免费出口端储气罐及入口端空气滤清器来确定罗茨91视频下载免费进风口，根据罗茨91视频下载免费工作原理，从进风口侧看入口端两个叶轮转向都是朝两侧壳体方向转动(这与齿轮油泵工作原理相同)，这样可确定主动叶轮旋转方向，从而也就确定了电机转向，注意事项与前面括号内所述内容相同。

　　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!
