Operation Steps of High Temperature Brazing Furnace

---

How to operate the high temperature brazing furnace more convenient? How to do daily maintenance work during use?

The operator of high temperature brazing furnace should understand various appearances, pumps, and various parts of brazing furnace equipment. Read and understand various manuals.

The pressure of the cooling water should be between 0.1 and 0.2 Mpa, and the outlet temperature should be ≤45°C.

The compressed air pressure is between 0.4 and 0.5 Mpa.

Before starting each furnace of continuous high-temperature brazing furnace, check the cylinder capacity of the maintenance gas to avoid lack of gas filling and replace the cylinder.

If there is any abnormality after starting up, it should be cleaned up immediately or shut down to find out the reason.

Always check the return water volume of each part of the mesh belt high temperature brazing furnace, and ensure that each part has enough cooling water during operation.

When the high-temperature aluminum brazing furnace equipment is out of service, the gas in the furnace should be exhausted. It is not necessary for a long time. It should be filled with maintenance gas and the circulating water in the water cooling jacket of the equipment should be discharged.

Mechanical pumps and Roots pumps should be changed and refueled regularly, and there must always be oil in the oil cup of the Roots pump. The waste oil must be cleaned when changing the oil.

When changing the oil of the dispersion pump, if there is oxidation inside, clean the oxide layer inside the dispersion pump, and then replace with new oil.

The purity of the maintenance gas filled into the atmosphere protection brazing furnace should not be less than 99.99%.

The natural gas brazing furnace equipment does not allow the use of flammable, explosive and corrosive gases as a maintenance atmosphere.

The appearance and appearance of the mesh belt brazing furnace equipment must be kept clean, and the inner wall of the scrubbing furnace is not allowed to be scrubbed with water and non-vacuum oil.

The oil-water separator on the pneumatic three-piece of the pneumatic system should always drain water, and the vacuum dispersion pump oil should be written into the oil mist device.

The voltage of the whole machine of continuous brazing furnace equipment should be ensured in the range of 350～420 V. The three phases should be balanced.

Regulators, electrical contact pressure gauges, thermocouples, etc. should always be coated with dispersed pump oil to form an oil film with the seat to avoid air leakage. The above parts and flange connections are not allowed to be sealed with vacuum sealing mud for a long time.
