Hot-sell series 400KW solid state induction heat treatment equipment

(1) The function of switch cabinet and rectification control are integrated here as a whole.

(2) Input line switch, input current meter, voltmeter(can be switched) and input voltage indicating light. 

(3) 3-phase thyrlstor rectifying bridge to achieve power adjustment of the HF welder. 

(1) MOSFET single-Phase inverter bridges connected in parallel.

(2) The inverter bridge adopts drawer type design and the building block method to realize power superposition.

(3) The matching transformer is adopted for power combination.

(4) Secondary resonance is used without welding transformer, the output arm offers required power transmission for pipe welding.

(5) Sealed equipment cabinet with air conditioner.

The console achieves remote control and power regulation of solid-state HF welder, installed with LCD ;also it has indicators of armature voltage, field voltage on DC drive cabinet and indicators of DC voltage, DC current on welder. Installation of power-speed closed loop control function is optional. The console has design difference according to different types and quantities of matching DC drive cabinet.

Air-water cooling equipment

- Air-water cooling equipment (not recommended, unless the customer uses water unconditionally).

Working principle:

- The cooling water is driven by the system circulation pump and circulates between the inside of the heat exchanger coil and the inside of the equipment, and the heat of the cooling water is conducted to the pipe wall. The spray water is evenly sprayed on the heat exchanger, and the cold air enters the tower from the bottom of the tower under the action of the fan, and flows back to the surface of the heat exchanger with the spray water. The spray water fully absorbs the heat of the coil and flows into the bottom of the tower. The water tank is transported to the spray system by the spray pump. Repeatedly, the cooling water in the heat exchanger is cooled down.

Composition:

- It is composed of shell, heat exchanger, fan, spray system, circulating pump, electric control and other parts.

Features:

- This system adopts a fully enclosed cycle, distilled water cooling (to avoid scaling).

- High heat dissipation efficiency and low operating cost.

- Small footprint.

Water-water cooling equipment 

- The water-water cooling system is composed of heat exchanger with the adoption of the special corrugated structure which makes the soft water form sharp turbulent flow in order to strengthen heat exchange.The system holds the advantages of compact design, small area occupation, convenient dismounting and high efficiency of heat exchange. Only with the ability of heat exchange but not cooling, it is necessary to use extremal circulation system to accomplish the heat exchange.
