Vacuum brazing furnaceProduct Introduction：

Vacuum brazing furnaces feature horizontal single-chamber and vertical bottom-loading structures. The furnace body and door are equipped with double-layer water cooling and a front-and-back door design. The high-vacuum brazing furnace consists of a vacuum system,

Furnace shell, heating chamber, control system, cooling system,Water-cooling system, inflation/deflation system, pneumatic system, temperature measurement system, and feeding mechanism, etc., are composed.

1. Furnace body:

Vacuum brazingThe furnace consists of components such as the furnace shell, furnace door, and furnace frame supports. The furnace shell and door feature a double-skin jacketed cold wall structure. The furnace door is equipped with a double-ellipse head and circular...

Welded in shape flange, equipped withO-ring seal, featuring an automatic lock and close structure with cylinder.

The workpieces of the horizontal vacuum brazing furnace can be loaded and unloaded through the front and rear furnace doors. In the middle, there is the main heating chamber, electrodes, and the exhaust port of the main vacuum pump.

The vertical vacuum brazing furnace door features a vertical lifting and lowering structure, equipped with a screw-driven lifting mechanism for automatic locking during opening and closing. Workpieces can be loaded and unloaded through the furnace door at the bottom.

The central section is equipped with the heating chamber main body, electrodes, and the exhaust port for the main vacuum pump.

2 Heating chamber:

The vacuum brazing furnace heating chamber consists of a stainless steel shell, insulating layer, insulating parts, workpiece support, and heating element.

The heater material is made of high-temperature molybdenum sheets. Depending on the working area size and temperature uniformity requirements of the heating chamber, the heater is configured with multiple heating zones or a single-chamber heating zone.

Heated by a regulator. Temperature in the heating zone is measured by a thermocouple. Used for random detection of the furnace temperature.

Insulation layer by Molybdenum SheetsStainless steel screen composition, clean inside the furnace, excellent heat preservation effect.

3、Vacuum System:

3.1 Vacuum brazing furnace vacuum system, equipped with diffusion pump vacuum unit according to vacuum requirements and process: diffusion pump, butterfly valve, Roots pump, molecular pump, mechanical pump

AndCombination of slide valve pumps and other configurations.Select based on the customer's vacuum degree requirements. Hunan Aipu provides professional selection services.

3.2、Vacuum detection points are installed on the upstream pipeline.To determine if the preliminary vacuum pump is operating normally.

3.3 The vacuum system does not use butterfly valves; instead, high-reliability airlock butterfly valves are employed.

3.4 The upper part of the diffusion pump is equipped with a low-temperature refrigeration cold trap to prevent the diffusion pump from oil backflow.Increase the vacuum level inside the vacuum chamber. Diffusion pump oil temperature is controlled by automatic temperature regulation technology.

Technique that can reduce the return oil of the pump。All contact parts with high vacuum (pipelines, valves) have inner walls made of stainless steel and are processed strictly according to high vacuum standards.

4. Electrical Control System:

Vacuum brazing furnace's electrical control systemComprising a touch screen, programmable logic controller, thyristor voltage regulator, vacuum gauge, and recorder, etc., for achieving power supply, control,

Record, monitor, and alarm protection features. Programmable Logic ControllerPLC utilizes Siemens CP series, temperature control with Japan's conductive FP93Accurately controls temperature.

At the same time,PLC fully controls the operation of equipment, providing sequential control signals according to process requirements, while simultaneously collecting feedback signals from the site, offering conversion, interlock,

Instructions and alarm signals. The entire process can be automated, except for loading and unloading, and is equipped with a manual operating system.

5. Water Cooling System:

Vacuum brazing furnace body, furnace door, vacuum unit, water-cooled electrodes, and heat exchange system require cooling water. The system distributes the main supply pipeline to each cooling section, utilizing a closed circuit.

Flow-through water recycling system, equipped with a water pressure alarm system. The incoming water is branched to the municipal water pipeline for emergency use in case of power outages. Both the incoming and outgoing water pipes are made of stainless steel.

Steel pipeline, with an electrode water inlet equipped with a scope for easy observation of the water flow inside the pipeline.
