Vacuum furnace maintenance technology

Because the types and forms of vacuum heat treatment to protect a lot, so the maintenance and overhaul project each are not identical. Maintenance check content should be based on the stove technology file and can be divided into every furnace according to the actual needs, daily, monthly, every half a year and every year for the project. The following eight o 'clock every furnace are summarized, the daily repair and maintenance projects.
1. To have spirit town function of the air pump, should be in the daily check and according to the need to be open before blowing in 30 min, to eliminate the moisture in oil pump.
2. Regularly check the cooling water, compressed air, hydraulic system pressure and the flow of cooling water.

6. Roots pump should be in above of 133 pa vacuum can start, also should have electric interlock protection device to protect.
7. To have compressed air piping, open the drain valve should be released water every day.
8. Often pay attention to the cooling water in and out of the water temperature indicator is normal, check the touch electrode joint, oven door, whether there are local in areas such as the transformer cooling water pipe temperature anomalies.
