Abstract
The utility model discloses a main-circulation main pump system of a pure water cooling device, which comprises two circulation main pumps which are connected with each other in parallel and corresponding main pump motors, wherein the input ends of the main pump motors are provided with two control ends which are connected with each other in parallel; and one control end is provided with a frequency converter. When the circulation main pump system works normally, one main pump works, and the other main pump is standby. When the main pump in use fails and can not work normally, the other main pump is switched for working. Two main pumps can both run with variable frequency or power frequency, and variable-frequency operation and power-frequency operation can be compensated mutually; and the starting and running of the system can both be maintained in an ideal state with less failure by combining the advantages of variable-frequency starting with the advantages of power-frequency running.
Description
Technical field
