你必须了解的奔驰空调系统维修注意事项

来源:http://www.jnrunao.com/ 日期:2021-08-06 发布人:runao
空调作为一个单独的循环系统,对它的维护和修理必 须要严格按照规定进行,主要有以下五个方面。
As a separate circulating system, the maintenance and repair of air conditioning must be carried out in strict accordance with the regulations, mainly in the following five aspects.
1.打开制冷剂管路后,应立即使用合适的密封塞将所有连接孔密封,防止湿气和灰尘进入系统导致制冷输出降低和造成部件损坏,例如空调不制冷、管路堵塞、压缩机损坏等;另外,必 须更换干燥罐。图3所示为制冷剂储液罐。
1. After opening the refrigerant pipeline, immediately seal all connecting holes with appropriate sealing plugs to prevent moisture and dust from entering the system, resulting in reduced refrigeration output and component damage, such as non refrigeration of air conditioner, pipeline blockage, compressor damage, etc; In addition, the drying tank must be replaced. Figure 3 shows the refrigerant reservoir.
2.所有新部件应存放在干燥、封闭的区域内,只能在安装的前一刻拆下密封塞。干燥罐或干燥剂应在打开包装后20min之内安装,然后仔细排空系统,进一步排出已渗 透的湿气。图4所示为带密封塞的压缩机。
2. All new parts shall be stored in a dry and closed area. The sealing plug can only be removed immediately before installation. The drying tank or desiccant shall be installed within 20min after opening the package, and then the system shall be carefully emptied to further discharge the infiltrated moisture. Figure 4 shows a compressor with a sealing plug.
3.当压缩机润滑油的颜色为黑色时,应立即检查空调管路;如果管路存在黑色粉末,说明压缩机已磨损,必 须更换,且还要对管路进行彻 底清洗。另外,在加注时必 须根据WIS要求校正机油和冷媒的加注量,防止加注不足或过多而引起的部件损坏。。
3. When the color of compressor lubricating oil is black, check the air conditioning pipeline immediately; If there is black powder in the pipeline, it indicates that the compressor has been worn and must be replaced, and the pipeline must be thoroughly cleaned. In addition, during filling, the filling amount of engine oil and refrigerant must be corrected according to wis requirements to prevent component damage caused by insufficient or excessive filling..
4.在雨季,电路容易遇水腐蚀,其后果可能导致线路短路,使包括空调系统在内的电控系统出现故障,严重的可引起火灾,烧毁车辆。因此,在雨天行驶尤其是涉水后,即使车辆正常行驶,也必 须到维修厂进行全 面检查,时刻注意电路防潮保养。图6所示为空调部件腐蚀情况。
4. In rainy season, the circuit is easy to be corroded by water, which may lead to short circuit of the line and failure of the electric control system including the air conditioning system, which may cause fire and burn the vehicle. Therefore, when driving in rainy days, especially after wading, even if the vehicle runs normally, you must go to the maintenance factory for comprehensive inspection and pay attention to the moisture-proof maintenance of the circuit at all times. Figure 6 shows the corrosion of air conditioning components.
5.在空调抽真空时,为了保证将空调系统内的空气与水分彻 底排空,抽真空的时间不要少于20min,将系统抽真空至500Pa,并在抽真空后封闭所有的阀和关闭抽注机,进行保压10min后观察空调系统是否存在泄漏。
5. When vacuumizing the air conditioner, in order to ensure that the air and moisture in the air conditioning system are completely drained, the vacuumizing time shall not be less than 20min, vacuumize the system to 500pa, close all valves and close the pumping unit after vacuumizing, and observe whether there is leakage in the air conditioning system after maintaining the pressure for 10min.
