Turning milling compound machining center operation of some conditions

2019-01-08 08:28:14

When parking, in order to make the motor quickly static, it is necessary to invert the motor power supply, the motor in reverse braking state quickly brake. Taiwan turning milling compound machining center if the motor speed is low, then rely on the speed relay KP1 or KP2 moving contact automatically cut off the control circuit, disconnect the motor power supply, the implementation of free parking.
When the motor of Taiwan turning and milling compound machining center turns forward, the positive rotation housing contact KPl (17-21) of the speed relay closes, while the positive rotation breaking contact KPl (17-18) disconnects. When the motor reverses, the reverse rotation contact KP2 (17-16) of the speed relay closes.
It is assumed that the main motor rotates at a low speed before stopping, i.e., Kl, KML, KM3 and KM4 are in the action state. Taiwan milling compound machining center speed relay moving contact KPl (17-21) closure. Taiwan turning and milling compound machining center press SB1, its dynamic break contact (8-7) make K1 and KM3 power off release, contact Kl (19-16) open, make KM1 power off release, this cut off the main motor power supply. CNC machine tool press SB1 at the same time, its moving contact (8-17) closed and connected the following tuen lu: from the power line (8) -sbl (8-17) -kpl (17-21) -kmi (21-20) -km2 coil a power line (". Taiwan turning milling compound machining center so that the reverse contactor KM2 electrical action, KM2 action, the moving table contact KM2(8-17) is connected to the self-locking line, when the release of the button SA1, KM2 still electrical action.
The KM2 contact (8-17) is closed instead of the KM1 contact (8-17) to keep KM4 - straight. KM2 and KM4 are energized so that the three-phase power supply is connected back to the motor through KM2 main contact, current limiting resistance R and KM4 main contact, and the motor is connected back to brake. When the motor speed is reduced to close to zero speed, the positive rotation contact of the speed relay KPl (17-21) opens and cuts off the power circuit of KM2, so that KM2 and KM4 are released successively. The reverse power supply of the motor is cut off in time, and the motor braking ends. The braking process in reverse operation is similar to that in forward operation. At this time, the electrical appliances involved in control are speed relay KP2, contactor KM1 and KM4.
