Make-Up Pump
Technical advantages
■Rigid shaft design, good rotor rigidity, meeting frequent start/stop requirements, and high reliability.
■The axial force is balanced using a double balance drum structure.
■The bearing adopts rolling bearing, oil-slinging ring structure, white lubrication, and air-cooling structure. It does not require pre-lubrication and auxiliary cooling system. It is reliable in operation and easy to inspect and maintain.
- Function
- Main parameters
■Provide makeup water to the reactor coolant system;
■Change or maintain the water chemistry of the reactor coolant and the water charge of the system;
■Provide auxiliary spray, etc. to the voltage regulator when necessary.
