Abstract

Abstract: This paper analyzes the scheme of positive pressure leak detection in water vapor jet pump for RH vacuum refining system and the difficulties in the application of this method in the mechanical vacuum pump system. We proposed a method of negative leak detection in the mechanical vacuum pump system, gave the theoretical analysis method, and also compared the theoretical analysis results with the actual test data. The actual leakage rate of vacuum system was measured and the equivalent hole size was calculated. The intelligent leak detection scheme of vacuum system of mechanical pump was discussed, which can quickly find the leak point position, improves the leak detection efficiency of vacuum system, and improves the intelligence level of RH vacuum refining unit.

Key words: RH, mechanical vacuum pump, negative leak detection, intelligence
