[introduction]Taiyuan automobile repair which best? Seven simple detection method for automobile air conditioner refrigerant leakage

    Taiyuan Jiete fast car repair that summer, refrigerant leakage is a common fault in the use of air conditioning. Some need to add refrigerant once a year, some may be added once every 2 months. Refrigerant leakage is easy to cause environmental pollution, in addition to increase the cost of vehicles and vehicle maintenance time. The following are seven kinds of methods of automobile air conditioner leak detection.

Automotive air conditioning refrigerant leakage

    Visual detection

    Find somewhere in the system oil leakage, here may be. Visual detection is simple, no cost, but there are many defects, unless the system suddenly breaking large leak, and leakage of liquid color media, or visual detection cannot locate, because usually leakage place very subtle, and the automobile air conditioner itself has a multi site almost can not see.

    Soapy water leak detection

    Filled to the system 10-20kgcm2 pressure of nitrogen, and in each part of system with soap water, bubble to leakage. This approach is currently the roadside repair leak detection methods of plant the most common, but the human arm is limited, the range of human vision is limited, a lot of the time did not look to the point.

    Nitrogen water leak detection

    Filled to the system 10-20kgcm2 pressure of nitrogen, the system is immersed in the water, bubble to leakage. Soapy water leak this approach and previous approaches is essentially the same, although the cost is low, but there are obvious shortcomings: leak detection using water is easy to enter the system, causing the system within the material corrosion, and high pressure gas may also cause more damage to the system, large labor intensity of leak detection, which makes the maintenance and overhaul the rise in the cost of.

    Halogen leak detection

    Light detector lamp, a halogen lamp on air tube, when the nozzle close to the system leak, the flame color changed to purple blue, that where a large number of leakage. In this way a fire, not only is very dangerous, and fire and refrigerant combination can produce harmful gases, moreover is not easy to accurately locate the leak. So this approach is now almost no one used, if you can see, it is not a civilized society is in the stage of.

    Gas differential pressure leak detection

    The pressure difference inside and outside the system, the differential pressure through the sensor amplification, expression of leak detection results in digital or sound or electronic signal mode. This method is only "qualitative" to know whether the system leakage and can not accurately find the leak.
