Operation controlling method for prevent water supply from overheating
专利汇可以提供Operation controlling method for prevent water supply from overheating专利检索，专利查询，专利分析的服务。并且PURPOSE: To stop automatically a water supply pump only when the pump is running at a critical range in such a cast that the water supply pressure exceeds the specified rating and/or (recirculation flow/discharge pressure) falls down to the specified value.
CONSTITUTION: BH (higher than the specified rating of the water supply pressure) designates to be higher than the pressure value which is obtained from the cross point between the minimum flow curve L and the water pipe head loss curve M. C indicates below the specified rating (recirculation flow/discharge pressure) and D indicates below the discharge flow rate QM which is obtained from the cross point between the maximum pressure value PM and the minimum flow curve L, which indicates the abnormal conditions. Hence, an alarm unit E is actuated to indicate the minimum water supply pump flow quantity at the range of BH and D to notify an operator. Besides, when the pump indicates the critical condition running at BH and D ranges and the circulation water quantity is ranged at C, the pump automatic stop unit F is actuated by the time limit relay RY with a certain delay time.
