Daqing Refining & Chemical Co., Ltd. Pump Remarkable Improvement

Recently, the Daqing Refining & Chemical Company's atmospheric and vacuum workshop has completed the transformation of three pumps such as softened water pumps. The power consumption has saved an average of 35% before the transformation, saving about 380,000 kWh annually, and saving more than 260,000 yuan. .

The technicians of Daqing Refining & Chemical Company's decompression workshop found that the opening of some pump outlet valves is small and the outlet pressure is high, resulting in a substantial increase in the cut-off losses and wasting electrical energy. In order to better match the operation of the pump with the actual production and improve the operating efficiency of the pump, the workshop organization analyzed and studied the pump with room for improvement. By comparing the operating data and operating conditions of the pump over the past three years, Combining the experience of retrofitting of the previous pump, the cutting amount of the pump impeller is accurately calculated to ensure that the pump can meet the production requirements after the retrofit, and the purpose of saving electricity can also be achieved. The pump operation can be close to the optimal state.
