What reliable circuits does the spline shaft quenching equipment have?

Spline shaft quenching equipment plays a very important role in industrial production. Reliable circuits must be used, otherwise it will not function and even some failures will occur. Therefore, when purchasing, users should not only understand the types of intermediate frequency induction heating equipment, but also understand what reliable circuits should be provided for spline shaft quenching equipment?

1. Inverter circuit

The spline shaft quenching equipment should have an inverter circuit. In order to have a stronger adaptability, a parallel resonant inverter should also be used to invert the three-phase rectified voltage into a single-phase intermediate frequency alternating current. If the input current is DC, the input voltage is a full-wave rectified waveform when the load resonant frequency is working, the output current is a square wave, and the output voltage is a sine wave, so it can be no-load, short-circuit and direct protection easy.

2. Filter circuit

The filter circuit uses a reactor. When the three-phase AC incoming line voltage is rectified by a three-phase fully-controlled rectifier bridge, it becomes a pulsating DC voltage signal of 300 Hz. Due to the existence of the reactor, the circuit of the spline shaft quenching equipment After filtering, it becomes a smoother DC voltage signal, and at the same time isolates the DC voltage signal at the rectifier end from the AC voltage signal at the inverter end.

3. Rectifier trigger circuit

The rectifier trigger circuit in the spline shaft quenching equipment includes three-phase synchronization, digital trigger, and final drive. The trigger part uses digital trigger, so it has the characteristics of high reliability, high precision and easy debugging, and the time required to record a certain number of pulses is relatively short, that is to say, the delay time is short.

In addition to the inverter circuit, filter circuit and rectifier trigger circuit, the spline shaft quenching equipment also includes a regulator circuit, an inverter trigger circuit and so on. If users want to purchase induction heating equipment with reliable performance, they should first understand how to choose intermediate frequency induction heating equipment, and see if the circuits in the instant heating equipment are reliable.
