Recently, Hengshui Board Manufacturing Department's grinding machine bearing heater electrical transformation was successful, the transformation cost less than one hundred yuan, not only realize all the functions of the original equipment, but also easy to learn in operation, convenient for employees to use.
The control principle of the bearing heater of the grinding machine is to control the triggering and conduction of the thyristor through the integrated circuit board. The parameter setting is realized by the operation panel. After nearly 3 years of frequent use, some buttons on the operation panel have been It is not very sensitive, which brings a lot of troubles to the use of employees. Since the operation panel and the integrated circuit board are integrated, if it takes nearly 3,000 yuan to replace the spare parts, in order to save costs and reduce unnecessary waste, the scale manufacturing department decides The electrical control system of the bearing heater is modified. The operation part is realized by the changeover switch. The timing is completed by the time relay. The trigger of the thyristor is controlled by the contact of the relay, and the transformation effect is good.
