Electrical machinery rotor end ring induction braze welding device

Specification:

The induction braze welding device is made of transistor tube frequency conversion power supply, middle frequency welding transformer, infrared thermometer, induction heater, cooling water unit as well as welding device supporting lathe.

The induction braze welding device is suitable for integrated braze welding and segment braze welding.

Models and technical parameters for reference:

Description:

This equipment is of strong technology with high degree of automatic, easy operation, good quality of workpiece welding.

The middle frequency braze welding equipment adopts middle frequency whole induction braze welding, the large power asynchronous tracking motor rotor end-ring and guide bar are completely welded with one-time heating. The welding period is short thus make the guide bar and end-ring be affected little by the heat. The mechanical strength of the welding is high, and the whole quality is excellent.

Proper choice on welding material and brazing flux, which makes the welding quality better.

Take advantage of induction heating which is of quick heating, little burning loss and high labor strength.

The infrared thermometer control system non-contact measurement on work-piece. And the control on the middle frequency power supply for the output power adjustment, thus making the temperature on the work-piece constant. The temperature control precision of the welding work-piece can be ± 2%.

The output power of the power supply does not vary when the induction coils and work-pieces change.

All-digital control system, no relay control.

The technology is divided into 2 kinds: overall braze welding and segment braze welding according to the diameter of the motor. If the motor's diameter is below 900mm, the overall braze welding is selected. Otherwise, the segment braze welding is selected.

Competetive advantage:

The braze welding device adopts proper transistor tube induction heating power supply, high heating efficiency, good welding quality.

The welding is suitable for whole braze welding and segment welding which can meet the requirement of silver-based and copper-based braze welding material.

World-leading welding technology support can decrease many users’ welding problems.

The welding strength and electricity conductivity all meet the requirement of technology.

Complete protection function on over-voltage, over-current, phase loss, low voltage, low pressure of cooling water, over-high temperature of cooling water etc.

Full digital control system for precise and real-time monitor and control.

Global leading welding procedure is adopted to solve many problems regarding the welding for the users.

This heating method has many advantages such as fast heating rate, less burning, low labor intensity and good quality. It can save 35% energy than old type valve high frequency power and 20% than controllable medium frequency power. It also has no noise. This product has an irreplaceable position on mechanical component welding and heat treatment industry with its superior performance.
