Abstract
the invention discloses a method for inspecting the tightness of a tank body of a sanitation truck, which comprises the following steps: cleaning the oil dirt impurities on the surfaces of the two sides of the welding line by using a cleaning agent; spraying a penetrating agent on the No. 1 surface of the welding line after five minutes; penetrating the penetrant from the No. 1 surface to the No. 2 surface, and spraying the developer on the No. 2 surface of the welding line after ten minutes; the developer shows a purple red color point on the No. 2 surface, so that the sealing is not good, and the sealing is good when the developer is colorless; and (5) wiping the auxiliary materials on the surface of the tank body by using wet cloth, keeping the surface of the tank body clean, and finishing the inspection. The method for detecting the tightness of the tank body of the sanitation truck replaces a wading/irrigation leakage detection method, can detect the completely closed tank body by using a set of special liquid solvent, can quickly detect the specific position of a welding seam leakage point of the tank body, and then accurately welds the leakage seam in time, thereby greatly shortening the detection time and improving the production efficiency of the sanitation truck.

background art:
the sanitation vehicle needs to store a large amount of water in daily work, so that high requirements are put on the sealing performance of the welding seam of the tank body. At present, most sanitation vehicle manufacturing companies adopt means such as wading/filling to test the tightness of the welding seam of the tank body, but some outstanding problems exist. The drainage is difficult after the closed tank body is filled with water, the time period of the filling leakage detection is too long, the specific position of a leakage point of a filling detection welding line is difficult to determine, and the specific position can not be determined for specific welding. The labor cost is high, and the production efficiency of a workshop is seriously hindered.
therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.

(1) cleaning the oil dirt impurities on the surfaces of the two sides of the welding line by using a cleaning agent;
(2) spraying a penetrating agent on the No. 1 surface of the welding line after five minutes;
(3) Penetrating the penetrant from the No. 1 surface to the No. 2 surface, and spraying the developer on the No. 2 surface of the welding line after ten minutes;
(4) the developer shows purple red color points on the No. 2 surface, so that the sealing is not good, and the sealing is good when the developer is colorless;
(5) And wiping the auxiliary materials on the surface of the tank body by using wet cloth, keeping the surface of the tank body clean, and finishing the inspection.
The invention also adopts the following technical scheme: a method for testing the sealing performance of a tank body of a sanitation truck comprises the following steps:
(1) Cleaning the oil dirt impurities on the surfaces of the two sides of the welding line by using a cleaning agent;
(2) Spraying a penetrating agent on the No. 1 surface of the welding line after five minutes;
(3) Ten minutes later, spraying a cleaning agent on the surface of the welding seam No. 1, and removing the penetrating agent on the surface of the No. 1 by using the cleaning agent;
(4) after three minutes, spraying the developer on the surface of the welding seam No. 1, sucking out the penetrant positioned in the surface of the No. 1 surface and the surface of the No. 2 surface by the original way of the developer, and performing physical reaction on the surface of the No. 1 surface to form a purple color point, wherein the sealing is not good, and the sealing is good if the penetrant is colorless;
(5) and wiping the auxiliary materials on the surface of the tank body by using wet cloth, keeping the surface of the tank body clean, and finishing the inspection.
