中频电源冷却系统故障的防范措施
[来源:www.zhongpinshebei.com] [作者:aywl] [日期:17-05-20]

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。 The cooling of medium frequency furnace and medium frequency power supply should be separately used independently of the whole closed cooling tower. The purpose of an independent cooling device is to avoid interaction. 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 Fault prevention measures for cooling water system 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。 The cooling water system is a basic guarantee of the normal operation of medium frequency and medium frequency furnace, because the main components of the whole system are water-cooled. So it is very important to monitor the cooling water system strictly. The failure of the water system may include the failure of the pump or pump motor, the water discharge from the water pump, and the breakdown of the cooling water hose. In order to detect these failures, the pressure gauge is installed in the water inlet of the cooling water system and the temperature sensor is installed on each cooling device. Signals from these sensors are sent to the control system to determine how the cooling water system works. These signals are interlocked with the medium frequency power supply. When the water system is hot, the water is low or the water flow is low, the medium frequency power supply will call the alarm and stop automatically.
