application case of circulating water
application introductionproduction water is injected into the coal water pool of circulating water field and pumped by circulating cold water pump to the heat exchanger of each production unit. after temperature rising, the circulating cooling water return is directly pumped to cooling tower under the residual pressure. the cooling tower is of counterflow type using mechanical ventilation. the inside hot water exchanges heat with cold air via medium and cools down. then it flows into the bottom collecting basin and suction basin before being pumped by circulating water pump to the circulating cold water pipe network. the circulating water pump and cooling tower fan can use frequency converter control to achieve the result of saving energy.
process characteristic
·starting with small electric current has small impact force for power grid and equipment.
·having good performance with load, the torque for starting with low frequency is larger.
·according to processing technic, the speed can be adjusted.
·with the function of rotate speed tracking, it can realize dynamic starting.
· with good over-load capacity and resistance for bad environment, it can operate stably in the long run.
