在机械工厂中,各种机床是用得最普遍的设备。这些机床在加工零件的过程中,由于要测量工件、更换刀具等等,常常要让机床停下来,这时,机床的马达却还在继续运转。这样,由于马达经常空载运转,就浪费了很多电力,例如,某厂机床空载损失达到用电量的30%。事实上,这种浪费电力的现象,在许多工厂都是相当严重的。如果在机床停歇下来的时候,我们能够使马达也停止运转,那末,电力的消耗就会大大减少。采用机床空载自动停车的装置,就能够达到这要求。目前 In machinery factories, all kinds of machine tools are the most commonly used equipment. These machine tools in the process of machining parts, due to the workpiece to be measured, the replacement of tools, etc., often to stop the machine, then the machine’s motor is still running. In this way, a lot of power is wasted because the motor is often idling, for example, a machine tool has a no-load loss of 30% of its electricity consumption. In fact, this waste of electricity is quite serious in many factories. If we can stop the motor while the machine is down, the power consumption will be greatly reduced. With the machine no-load automatic parking device, will be able to meet this requirement. Currently
