vacuum braze furnace solutions

---

1. operators should understand various parts of appearance,vacuum pump and equipment. Read and understand various manuals.

2. the water pressure of cooling water should be between 0.1 and 0.2 Mpa, and the effluent temperature is less than 45 degrees Celsius.

3. Compressed air pressure is between 0.4 and 0.5 Mpa.

4. before starting the boiler, we should check the cylinder capacity of the maintenance gas, avoid the lack of gas filling, and replace the gas cylinder.

5. if there is any abnormal situation after starting, it should be immediately removed or stopped to find out the reason.

6. Always check the backwater volume of each part. Ensure that each part has enough cooling water during operation.

7. When the equipment stops operating, the gas in the furnace should be pumped out, long-term need not be filled with maintenance gas, and the circulating water in the water-cooled jacket of the equipment should be discharged.

8. mechanical vacuum pumps and Roots vacuum pumps should be regularly refueling. The oil cups of Roots pumps should always be oil. Oil must be cleaned when changing oil.

9. Disperse pump oil, if there is oxidation inside, to dispose of the internal oxidation layer of the disperse pump clean, and then replace with new oil.

10. the purity of the maintained gas should not be less than 99.99%.

11. vacuum braze furnace does not allow the use of flammable, explosive and corrosive gases as a maintenance atmosphere.

12. The appearance and appearance of vacuum braze furnace should be kept clean, and the inner wall of the scrubbing furnace should not be allowed to be scrubbed with a cloth containing water and non-vacuum oil.

13. The oil-water separator on the pneumatic three-piece of the pneumatic system should discharge water frequently, and the vacuum dispersing pump oil should be written into the oil mist separator.

14. the whole machine voltage should be kept within the range of 350~420 V. Three phase to balance.

15. Regulators, electrical contact pressure gauges, thermocouples and other places to be often coated with dispersed pump oil, so that between the seat and form a layer of oil film, to avoid leakage. The above parts and flange connections are not allowed to be sealed with vacuum seals for long time.
