The treatment method of the welding machine drying method after the DC gear motor is damp

Release time: 2022-06-24

1. Before the drying method of the AC welding machine is operated, connect the terminals of the damped deceleration motor windings in series, and the casing is grounded, so that the three sets of windings can be heated and dried. In order to monitor the current change during the drying process, a Only the ammeter is used to observe whether the current reaches the rated current of the geared motor. Drying the DC geared motor with an AC welding machine does not require disassembly and inspection, which reduces the workload. At the same time, the geared motor uses its own resistance to heat up when the power is on, so that the coil is heated evenly, and the drying effect is better.

2. The operation wiring of the DC geared motor electric welding machine is similar to that of the AC, and the series ammeter should be a DC ammeter. Drying the damp geared motor with a DC welding machine is easy to operate, and can dry large and medium-sized geared motors and high-voltage geared motors for a long time. In this way, when the electric welding machine works for a long time or with a high current, its internal components will not be damaged due to long time high current operation, so it can be used for a long time for large and medium-sized geared motors. It is worth noting that when drying with these two methods, it is required that all the joints must be in good contact and tightened, and the lead wire of the electric welding machine should use a special wire, and the cross-sectional size should meet the current carrying capacity of the output current of the electric welding machine. Pay attention to the cooling of the welding machine's own transformer, and at the same time ensure that the insulation resistance of the geared motor cannot be lower than 0.1MΩ. Also pay close attention to the winding temperature of the geared motor and adjust the voltage and current in time.
