二、电动机的安装(一)安装场所的选择电动机安装位置的选择原则是:1.安装电动机时,必须以轴承注油、滑环检修、碳刷更换、维护方便等为原则。但潜水电机例外。2.安装整流子或有滑环的开启式电机时,由于有产生火花的危险,因此,必须使火花不能达到附近的易燃物质,或者加装防护罩。但这并不意味着整流子或滑环电动机就不能安装在木质楼板结构的场所。(二)电动机的基础工程为了使安装的电机不产生振动,因此通常先用混凝土筑好墩子(如图103所示),然后将电机安装在墩
Second, the installation of the motor (a) the choice of installation location Selection principle of the motor installation location is: 1. When installing the motor, must be the principle of bearing lubrication, slip ring maintenance, carbon brush replacement, easy maintenance and so on. But with the exception of submersible motors. 2. When installing a commutator or an open type motor with a slip ring, it is necessary to make the spark not reach a nearby flammable substance or to install a protective cover because of the risk of sparking. But this does not mean that the commutator or slip ring motor can not be installed in the place of the wooden floor structure. (2) The basic engineering of the electric motor In order to prevent vibration of the installed motor, usually the concrete is first built (as shown in Fig. 103), and then the motor is installed on the pier.
