Characteristic description of abnormal temperature of compressor
The condensing valve is a valve used to remove condensate and air from the system, and the potential heat loss is large. The thermal imaging camera can monitor the working condition of the condensing valve to determine the steam utilization efficiency and avoid energy waste and leakage accidents. Abnormal temperature of condensing valve: 1. The inlet temperature is significantly lower than the system temperature: the steam does not reach the steam trap because the upstream high-temperature gas does not come over, causing the system to fail to work. 2. The inlet and outlet temperatures are the same: the condensing valve may be opened due to malfunction, which is a significant energy loss. 3. The inlet and outlet temperatures are low: it means that the condensing valve is closed due to a malfunction, which may cause an accident. Characteristic description of compressor temperature abnormality: 1. The inlet temperature is lower than the system temperature: it is because there is no high-temperature gas coming from the inlet. The reason may be that the front part of the valve is closed or the pipeline is blocked. 2. The temperature of the inlet and outlet are the same: there is no temperature difference, indicating that the condensing valve may be opened, and the heat energy is exchanged, resulting in the same temperature. As a result, continuous energy loss will occur, and in this case, the system can still operate. 3. The temperature difference between the inlet and outlet is not large and low: The phenomenon indicates that the condensate may be pouring into the inlet line of the condensing and condensing valve because the condensing valve is closed due to a malfunction. Why use infrared thermal image detection? Compared with the original traditional method of detection, the thermal imager has obvious advantages: 1. Can significantly improve the detection efficiency; 2. Due to the non-contact, the safety is high; The basis of infrared thermal image detection of condensing valve According to the working content and experience of the condenser valve: 1. The thermal image shows a lower inlet temperature (above ambient temperature ﹤20°C), or a higher outlet temperature (﹥100°C), indicating that the condenser valve is not working properly. 2. If the temperature difference between the inlet temperature and the outlet temperature is displayed <20°C, it means that the condensing valve may be opened and energy is wasted. Thermal imaging camera maintenance and testing recommendations for the condensing valve: 1. Check all condensing valves in the facility at least once a year. Larger or more critical valves should be inspected more frequently because of the potential for greater heat loss; 2. It is recommended to use a thermal imager to detect when the system is running: whether the pipeline is blocked (including closed valves), whether the underground pipeline is leaking, whether the heat exchanger is blocked, and the boiler (especially its refractory materials and Insulation layer), whether there is any abnormality in the equipment using steam, and the place that has been recently repaired to confirm whether the repair is effective. 3. The temperature of steam is very high, and it is usually delivered under very high pressure. Therefore, the highest maintenance priority should be given to the conditions that can bring about safety hazards. How to use a thermal imager for inspection? Since the equipment may be relatively large and have many parts, we recommend: 1) When testing, pay attention to testing as carefully as possible to avoid missing detection. 2) If the heat map is not clear in automatic mode, you can first use the automatic mode to measure the temperature range of the oil pillow; then manually set the level and span, set the temperature range to the minimum, and include the previously measured temperature range (various instruments) The minimum temperature range is different). 3) The general working conditions on site are similar, and the temperature at the same position in different phases can be compared, so that faults or hidden dangers can be quickly found. 4) Whenever you find a problem with a thermal imager, please use the relevant software to record the results in a report, including a thermal image and digital image of the device. Industry application: Typical application industries are: petroleum, chemical, pharmaceutical, metallurgy, etc.
