Problems solved by technology
[0004] 1. Since the total flow at the water outlet of the main pump is adjusted each time, it is difficult to control the flow distribution on the top surface and the side, and it is impossible to accurately control the flow of each branch
[0005] 2. During use, the flow of each branch will change due to the blockage of the sprinkler head, filter and pipeline. It may happen that the flow of the spray surface is not within the range of the national standard, and the equipment is still in use without alarm. Happening
However, it is troublesome to adjust the spray volume in the three branch pipelines by adjusting the main pipeline, and it is difficult to achieve a better state.
In addition, in actual use, as the status of the filter 2 and sprinkler head (attached to the top sprinkler pipeline 5 and side sprinkler pipeline 6) of the rain shower system changes, the top and left and right side flow rates will vary. Changes, problems cannot be found in real time, only through recalibration
It may cause a large number of complete vehicles not to be inspected according to the standard, and there are certain quality hidden dangers

The invention discloses an entire-car sealing performance detection system. A rainwater spray test is performed on the entire car in a rain room (7), the system comprises a main pump (1), a filter (2), a top spray pipeline (5) and a side face spray pipeline (6), and a flow regulating valve is respectively arranged on each spray pipeline of the top spray pipeline (5) and the side face spray pipeline (6). The invention further provides a rain spray test method adopted by the entire-car sealing performance detection system. By adopting the technical proposal, the system can cause the spray pipelines to perform flow control independently, can meet the requirement of the real operating status and perform real-time detection; and the system can adopt different ways to give an alarm when the system is not consistent with the requirement, thus the operation is more convenient.
Description
technical field [0001] The invention belongs to the technical field of automobile manufacturing process equipment, and relates to detection equipment for a complete automobile. More specifically, the invention relates to a detection system for the sealing performance of a complete automobile. In addition, the invention also relates to the rainwater spraying test method adopted by the vehicle sealing performance testing system. Background technique [0002] Before the whole vehicle leaves the factory, the automobile manufacturing enterprise uses the rain equipment to test the whole vehicle in the rain to test the airtightness of the vehicle body. According to the national standard, when the rain shower equipment detects the rain on the whole vehicle, the amount of spraying on the top and the amount of spraying on the side are different. Generally, when the rain shower equipment is in the rain, the main pump supplies water to the top, left side, and right side, and a flow met...
