中频炉冷却水系统简介 Intermediate frequency furnace cooling water system 全封闭冷却水系统包括冷却塔,水泵,高位水箱,储水箱和配套的用于水温,水压,流量检测的传感器和仪表。冷却装置的核心是喷淋蒸发式封闭冷却塔。在冷却塔内部有许多散热盘管,循环水在盘管内部流动,与空气不接触。冷却塔的下面有集水盘,内装喷淋用水,集水盘的进水口装有浮球阀,能够自动控制集水盘内的水位,出水口有喷淋水泵。冷却塔的上部装有喷水口和冷却风机。工作时喷淋水泵将水泵到上部的喷水口,将水打散呈细水珠状喷到盘管外表面,冷却风机同时抽风,使喷淋水汽化从而带走盘管内循环水的热量。 Closed cooling water system including the cooling tower, water pump, high water tank, storage tank and matching for water temperature, pressure, flow detection sensors and instrumentation. At the heart of the cooling device is spray evaporative cooling towers, closed. There are many cooling coil inside the cooling tower, circulating water flow inside the coil, do not contact with air. Within the bottom of the cooling tower water dish, water spray, water pan is the water inlet is equipped with floating ball valve, automatically control the water level in the water dish, spray pump outlet. The upper portion of the cooling tower is equipped with water and cooling fan. Work spray pump will pump water to the upper part of the mouth, break up is fine water spray the water to the coil surface, cooling fan convulsions, at the same time make spray evaporative water take away heat coil circulating water. 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.
