Cage welding machine troubleshooting method

Cage welding machine in the use of this equipment, due to various reasons will present some problems, and these problems must be timely cleaning. Below, I will give you a brief introduction to the common welding machine troubleshooting methods.

First, mechanical problems

The rotor and stator of the motor of the welding machine are worn, perhaps the bearing is worn, the gap is too large, and the phenomenon of forward transmission and reversal is generally present. At this time, the motor can be operated by hand, and the gap can be generally felt. If this is the case, it needs to be dismantled and repaired.

Second, the three-phase motor may be unbalanced

Three-phase asynchronous motor one of the phase of the power supply break, will present a lack of phase, severe imbalance, hob welding opportunity to present the above mentioned sometimes positive, sometimes rotating phenomenon, motor phase is a more serious problem, need to be dealt with in time, otherwise, will burn the motor, this with a multimeter or through the three-phase pliers meter to measure voltage and current resistance to identify.

Three, the motor is weak

Assuming that some loads have resilience, such as the water hammer piled up inside the pump, and the motor itself due to magnetic leakage and other reasons, and constitute a lack of initiating torque, these water hammers and other loads may also twist the motor in turn, this situation can be disconnected from the load to determine whether this problem can be presented.

4. Initiating circuit problem

If there is a positive rotation control in the circuit of the hob-welder, it may be that there are some problems on the control line, or it may be that a component is damaged when it is launched, the wrong action on the rotation, then, presenting this situation requires looking at the circuit diagram to sweep one by one, you can cancel the rotation component, and then see if this problem will occur.
