AI Technical Summary
When the main helium blower of the high-temperature gas-cooled reactor is running at 100% rated speed, the flow resistance decreases, which leads to an increase in flow rate and causes the current to exceed the limit, affecting safe operation and making it impossible to conduct a full-speed test.
The operating parameters of the main helium blower at normal temperature and pressure are obtained through actual test measurements. The theoretical parameters at different speeds are calculated. The helium pressure at the hot test temperature is calculated in combination with the gas characteristics. Equivalent tests are conducted to simulate the operating parameters across the entire speed range. If overload or overcurrent conditions occur, the pressure is reduced for adjustment.
The main helium blower was tested at full speed within the range of 0%-100% of its rated speed, effectively preventing overload operation and ensuring that the test was completed under safe and stable conditions.
