3, sealing the rain test. Tightness test body is to examine the quality of the central part of the manufacturing, inspection and testing requirements for rain assembly members should be familiar with the structure and quality of the body, so as not to generate false positives when determining the test results and miscarriage of justice. Specific methods rain tightness test as follows: ① the vehicle parked in the rain indoor specified location. ② inspectors into the cab cab diagram, and then close the doors, windows and manhole covers. ③ start the rain cab equipment change, to be the water into the steady state (typically 2min) test cab began to rain, rain record time, observe and record the car flashing the seals. ④ When the rain test cab window, related seepage, leakage judge the situation: seepage: Water slowly emerge from the cracks in the surface and attached to the body, including protecting spill phenomenon; drip: Water droplets emerge from the cracks in a in the body surface intermittently falling phenomenon; water: water emerges from the gap, and along or away from the inner body to continuously flow around the phenomenon. ⑤ reaches a predetermined time after the rain, rain shut down the device, the end of the test. ⑥ To ensure product quality, new products manufactured car should be able to reach Delong cab, cab Shaanqi no leakage requirements. Delong cab correct approach should be a pot of room temperature water will pour around windshield and window glass, when these do not affect the line of sight of the snow is removed, it can first car on the road, the body temperature rises as the vehicle of snow Nature will slowly melt. Some owners use wipers to snow is very dangerous. This may damage the wiper motor, wiper blades may also be damaged. Further, the glass of water with antifreeze function should choose. If you do not freeze, ice crystals will increase the volume of liquid, it is possible to support a bad glass kettle, resulting in unnecessary losses. Window glass and the front and rear windshield blooming inside and outside mainly because of a difference caused by temperature, so you want to defrost, you must first change the temperature difference between inside and outside.
