Ltd. is a subsidiary of SCG and is an important force in the domestic photovoltaic glass industry. The company has invested more than RMB 700 million in the first phase, covering an area of 385 mu, and has a production line for photovoltaic rolled glass and a supporting production line for deep processing of photovoltaic glass, which is the largest production base for deep processing of glass in East China.
Project content
According to the characteristics and operation requirements of the system, the original energy-inefficient pumps were replaced with ARMSTRONG intelligent inverter pumps and a remote data collection system was installed to monitor the operation of the pumps remotely and in real time via computers and mobile phones.
Solutions
Using ARMSTRONG intelligent inverter pump built-in PSPC control technology, control the pump start and stop and the number of operating units, to obtain the best operating efficiency, so as to ensure that the pump unit in the best energy efficiency to meet the system demand to run the system required flow, to achieve maximum energy saving.
