空调故障常见问题及五大检测方法

来源:http://www.jnslshwx.com 日期:2017-10-09 发布人:admin
一、看。济南空调维修观察空调器各部件的工作情况,重点观察制冷系统、电气系统、风系统三部分,判断它们工作是否正常,是维修前期检测的重要步骤。
First, look. Ji'nan air conditioning maintenance observation of the various parts of the air conditioner work, focusing on refrigeration systems, electrical systems, wind system three parts, to determine whether they work properly, is an important step in early detection of maintenance.
二、听。通电开机细听空调器压缩机运转声音是否正常,有无异常声音,风扇运转有无杂音,噪音是否过大等。在运行中,正常情况下振动轻微、噪声较小,一般在50DB以下。
Two listen. Power on, listen carefully to the air conditioner compressor operation sound is normal, whether or not abnormal sound, fan operation noise, noise is too big, etc.. In operation, under normal circumstances, slight vibration, noise less, generally less than 50DB.
三、摸。用手摸空调器有关部位感受其冷热、振颤等情况,有助于判断故障性质与部位。正常情况下,冷凝器的温度是自上而下逐渐下降,下部的温度稍高于环境温度。
Three, touch. It is helpful to judge the nature and position of the fault by touching the parts of the air conditioner and feeling its thermal, vibration and vibration. Under normal circumstances, the condenser temperature is down from top to bottom, and the lower part of the temperature is slightly higher than the ambient temperature.
四、测。济南空调维修为了准确判断故障的性质与部位,常常要用仪器、仪表检查测量空调器的性能参数和状态。如用检漏仪检查有无制冷剂泄漏;用万用表测量电源电压、各接线端对地电流及运转电流是否符合要求,由电脑控制的空调器,还应测量各控制点的电位是否正常等。
Four, measurement. In order to judge the nature and position of the fault accurately, it is necessary to check and measure the performance parameters and status of the air conditioner by instruments and meters in Ji'nan. As with a leak detector to check refrigerant leakage; the multimeter is used to measure the voltage of the power supply, the terminal of current and operating current is in accordance with the requirements, the air conditioner is controlled by computer, should also be potential measurements of each control point is normal.
五、析。经过上述几种检查手段所获得的结果,大多只能反映某种局部状态。空调器各部分之间是彼此联系、互相影响的,一种故障现象可能有多种原因,而一种原因也可能产生多种故障。因此,对局部因素要进行综合比较分析,从而全面准确地判定故障的性质与部位。
Five, analysis. The results obtained by the above inspection methods mostly reflect only some local states. Each part of the air conditioner is connected with each other and affects each other. There may be a variety of reasons for a fault, and one cause may cause many kinds of faults. Therefore, the local factors should be comprehensively analyzed and compared, so as to determine the nature and location of the fault comprehensively and accurately.
