水系统布置要点 Water system arrangement 中频炉及中频电源的冷却应分别采用各自独立的全封闭冷却塔。采用相互独立的冷却装置的目的是为了避免相互影响。因为中频电源需要低温的冷却水,出水温度要控制在50以内,但电炉感应线圈的冷却水温度可以略高,这样反而能够提高电炉的热效率,同时减小冷却装置的体积,进而减低造价。 Intermediate frequency furnace and medium frequency power supply cooling should be used respectively independent closed cooling tower. Adopt independent of each other is the purpose of the cooling device in order to avoid influence each other. As intermediate frequency power supply need to low temperature of cooling water, the water temperature to control within 50, but electric furnace cooling water temperature of the induction coil can be slightly tall, so it can enhance the heat efficiency of furnace, at the same time reduce the volume of a cooling device, thus reducing cost. 冷却水系统的故障预防措施 Failure of the cooling water system for preventive measures 冷却水系统是中频电源和中频炉正常工作的基本保证,因为整个系统的主要器件都是水冷的。所以对冷却水系统进行严格的监控是非常重要的。通常水系统可能出现的故障包括水泵或水泵电机损坏,水泵漏水造成水流量不足,冷却水软管破裂等。为了能够检测到这些故障,需要在冷却水系统的进水处安装压力表,在每个水冷器件上安装了温度传感器。这些传感器的信号都送到控制系统,控制系统据此判断冷却水系统的工作情况。这些信号与中频电源联锁。当水系统出现水温高,水压低或水流量不足时,中频电源会报警并自动停机。 Cooling water system is the basic guarantee for the normal work of the medium frequency power supply and medium frequency furnace, because the whole system's main components are water cooled. So for strict monitoring of cooling water system is very important. Possible failure usually water system including water pump or pump motor damage, water pump leaking caused by water flow is insufficient, the cooling water hose burst, etc. In order to be able to detect these faults, it is necessary to install in cooling water system of feed water pressure gauges, temperature sensors on each water-cooling device installed. These sensors signals are sent to the control system, control system on the basis of judging the performance of the cooling water system. These signals and intermediate frequency power supply chain. When there is high temperature water system, water down or insufficient water flow, the intermediate frequency power supply will alarm and automatically stop.
