几种导致空调漏氟的原因与维修
Several Causes and Maintenance of Fluorine Leakage in Air Conditioning
1、空调漏氟是喇叭口制作不良导致
1. Air conditioning fluorine leakage is caused by poor manufacturing of the bell mouth
漏氟原因：
Reason for fluoride leakage:
a、喇叭口边沿重叠;
a. The edge of the bell mouth overlaps;
b、扩口前切割连接型线  流水槽模具 景观石 检查井钢模具 保定通风管道 隔离墩模具 保定保洁公司管出现偏斜;
b. Deviation in cutting the connecting pipe before expanding;
c、连接管壁厚不均造成喇叭口制作壁厚不均匀;
c. The uneven wall thickness of the connecting pipe causes uneven wall thickness in the production of the bell mouth;
d、喇叭口制作尺寸过小或过大;
d. The production size of the bell mouth is too small or too large;
e、内壁有切屑、毛刺;
e. There are chips and burrs on the inner wall;
f、喇叭口有裂口;
f. There is a crack in the bell mouth;
g、喇叭口内壁划伤。处理措施：严格按照扩口工艺的要求制作喇叭口，使其喇叭口的表面光滑，周边均匀;连接管需平直，严禁选用未整理的弯曲不平连接管进行扩制喇叭口。
g. Scratches on the inner wall of the bell mouth. Treatment measures: Strictly follow the requirements of the expanding process to make the bell mouth smooth and uniform on the periphery; The connecting pipe should be straight, and it is strictly prohibited to use unorganized curved and uneven connecting pipes for expanding the bell mouth.
2、空调漏氟是管接头处未涂冷冻油导致
2. Air conditioning fluorine leakage is caused by the failure to apply refrigerant oil at the pipe joint
漏氟原因：安装或维修时，空调室内外机连接管口处未涂冷冻油;或管道固定密封不良，造成空调漏氟。处理措施：将冷冻油均匀涂在连接管内外接头处，调整好管路的位置，紧固空调室内外机连接管的漏氟出铜帽，按安装工艺定量追加检漏。
Reason for fluorine leakage: During installation or maintenance, the connecting pipe mouth of the indoor and outdoor units of the air conditioner was not coated with refrigerant oil; Or poor sealing of the pipeline, causing fluorine leakage in the air conditioner. Treatment measures: Apply refrigerant oil evenly to the inner and outer joints of the connecting pipe, adjust the position of the pipeline, tighten the copper cap for fluorine leakage from the connecting pipe of the indoor and outdoor units of the air conditioner, and add a quantitative leak detection according to the installation process.
3、空调漏氟是喇叭口与截止阀面安装不到位导致
3. Air conditioning fluorine leakage is caused by inadequate installation of the bell mouth and shut-off valve surface
漏氟原因：喇叭口与截止阀面或内机蒸发器接头处，在连接前进行固定，或连接偏移过大，造成紧固不均匀。处理措施：用手将喇叭口固定在接头正中位置，同时固定螺帽，保证固定到位。
Reason for fluorine leakage: The connection between the bell mouth and the shut-off valve surface or the internal evaporator joint was fixed before connection, or the connection offset was too large, resulting in uneven tightening. Treatment measure: Fix the bell mouth in the center of the joint by hand, while fixing the nut to ensure it is fixed in place.
4、空调漏氟是什么原因造成的-管路故障
4. What is the cause of fluorine leakage in air conditioning - pipeline failure
漏氟原因：空调室内外机连接管布管时，管路弯曲角度太小，也会致使管道弯裂漏氟或无氟。处理措施：在空调室内外机连接管布管时，将管路弯曲半径适量加大，防止管道弯死;对应漏氟的管道应及时进行补焊或更换。
Reason for fluorine leakage: When laying the connecting pipes of indoor and outdoor air conditioning units, the bending angle of the pipes is too small, which can also cause the pipes to crack and leak fluorine or have no fluorine. Treatment measures: When laying pipes for connecting indoor and outdoor units of air conditioning, increase the bending radius of the pipes appropriately to prevent them from bending dead; The pipeline corresponding to fluorine leakage should be repaired or replaced in a timely manner.
5、空调漏氟是制冷系统有漏点导致
5. Air conditioning fluorine leakage is caused by leakage points in the refrigeration system
漏氟原因：在更换制冷系统零件时，零件的二次安装不严密，会使管路及制冷系统存在漏氟点。处理措施：将不太浓的肥皂水涂在整机制冷系统管路、有焊接点的部位进行检漏。检测条件要求制冷系统充氮或充氟，注意仔细检查管路油污处，依次查出漏点，根据实际情况进行零件维修或更换。
Reason for fluorine leakage: When replacing refrigeration system parts, the secondary installation of the parts is not tight, which can cause fluorine leakage points in the pipeline and refrigeration system. Treatment measure: Apply less concentrated soapy water to the refrigeration system pipelines and welding points of the entire machine for leak detection. The detection conditions require the refrigeration system to be filled with nitrogen or fluorine. Pay attention to carefully checking the oil stains in the pipeline, identify the leakage points in sequence, and repair or replace the parts according to the actual situation.
