山东耐火材料厂在出砖装置上,系使用转盘操作台的摩擦机上的电动倒正回转出模装置。这种装置是属于通过伞形齿轮使丝杆上下下而出砖坯这一类的。过去,系利用手动的摩擦离合器和齿形的离合器使伞形齿轮倒正回转的。缺点是:操作紧张,使用不便,效率不高,设备事故多而检修麻烦。现在,在上述设备的基础上,运用“电动机中的三相线,任意变更其二相线的接,可以改变电动机的旋转磁场,使马达倒转”的原理,设计了一套电工线路(图1)应用在出砖装置上,使得手动操作变为只按一下电钮的自动操作,这样大大地减少了操作手续。经一年来的使用结果,效率较过去提高50%。缺点:夏
Shandong refractories plant in the brick unit, the Department of the use of the rotary table friction machine electric inverted rotary die device. This device belongs to the umbrella gear through the screw up and down out of this type of brick. In the past, the use of manual friction clutch and toothed clutch positive bevel gear rotation. Drawbacks are: tight operation, inconvenience, inefficiency, equipment accidents and maintenance trouble. Now, on the basis of the above equipment, using the principle of “three-phase line in motor, arbitrarily changing the connection of two-phase line and changing the rotating magnetic field of the motor to make the motor reverse”, an electric circuit is designed ) Applied to the brick device, making the manual operation to press the push button automatic operation, thus greatly reducing the operating procedures. After a year of use results, the efficiency increased by 50% over the past. Disadvantages: summer
