C 9220 A液压半自动车床是用交流电磁铁来控制液压换向阀的。在生产过程中由于刀架起动频繁,促使交流线圈经常受到起动大电流的冲击把线圈烧坏;同时,当电磁铁内部进去杂物或螺丝松动时都会造成卡住或吸合不上,也会使线圈电流比正常电流增大十几倍,造成烧坏线圈和发生生产事故。为此,我们厂把交流电磁铁改成直流电磁铁,消除了线圈被烧坏及生产事故。
C 9220 A hydraulic semi-automatic lathe is the use of AC solenoids to control the hydraulic valve. In the production process due to frequent turret start, prompting the AC coil is often affected by the impact of starting a large current to burn the coil; the same time, when the electromagnet inside the debris or screw loose will cause stuck or not pull, will So that the current coil than the normal increase of more than ten times, resulting in burning coil and the occurrence of production accidents. To this end, we plant the exchange of electromagnets into DC electromagnets, eliminating the coil is burned and production accidents.
