Maintenance of vacuum furnace

Do you know about the maintenance of vacuum furnace? The following vacuum furnace manufacturers will tell you in detail:

Because there are many types and types of vacuum furnaces, the maintenance and repair items are different. The maintenance and inspection content should be based on the furnace technical documents and can be divided into each furnace, daily, monthly, semi-annual and yearly Projects underway. The editor summarized the maintenance and overhaul projects carried out every heat and daily at 6 o'clock, I hope it will be useful to everyone!

Daily maintenance

1. For the empty pump with gas ballast function, check it before opening the furnace every day and open it for 30 minutes as needed to remove the water in the pump oil.

2. Frequently check the pressure of cooling water, compressed air, hydraulic system and the flow of cooling water.

3. The rubber seals and flange surface of the furnace door should be inspected before closing the guard door. There should be no sand and debris. Wipe the rubber seal ring and flange surface with a Qianjing cloth, and then evenly apply vacuum grease to the back The furnace door can be closed.

4. The workpiece must be cleaned before being processed in the furnace. After the oil quenching treatment, all the oil on the oil-soaked material frame and the carrying parts should be cleaned.

5. Air-cooled motors are generally commonly used motors. They cannot be started under vacuum and must be inflated before starting and should be protected by electrical interlocking protection devices.

6. Roots pumps should be started with a vacuum above 133Pa, and should also be protected by electrical interlocking protection devices.

In addition, for pipelines with compressed air, the drain valve should be opened every day to release accumulated water. , Suzhou electric furnace manufacturer reminds you to always pay attention to whether the cooling water inlet and outlet temperature indications are normal, and always check whether there are local temperature abnormalities in the touch electrode joints, furnace doors, transformer cooling water pipes and other parts.
