What are the main causes of rust in sweepers

There are many reasons for the rust of the car body. Hubei Junlong Special Vehicle Co., Ltd. introduces those problems。

　　1The rotation between the hinge holes of the body shaft。

　　2The impact and sliding between the lock tongue and the lock buckle, and the intermittent impact between the shoulder limit plate of the lock tongue。

　　3Chemical corrosion occurs when exposed to chemicals。Rear cab under skirt sandwich。 What are the reasons for the cracks or cracks in the body of the road sweeper? The reason why the body of the rail press block has cracks or cracks;Sheet metal parts in the process of manufacturing forming or welding, resulting in internal stress;

　　4The loose hinge hole shaft causes the door to sink, and the appearance under the door conflicts with the door frame。 The oscillatory contact and relative dislocation conflict between the lower surface of the engine hood and the upper surface of the radiator and the upper surface of the fender plate。 The bolt holes of the sheet metal bolts are worn out after the bolts are loosened, causing the aperture to increase。

　　What are the reasons for the rust of the body of the road sweeper and the reasons for the foaming and peeling of the coating film and the components? After welding repair, it is not treated with rust and leads to rust。Reason: There is mud and water on the surface of the metal, which causes oxidation and corrosion。

When the car is moving, the sheet metal parts are subjected to alternating loads due to constant oscillations of the body;When the car acceleration, emergency braking and turning sharp corners, the body is subjected to the effect of inertial force and centrifugal force。When the road sweeper passes through the road in poor condition, the sheet metal parts bear torsion force, and the body has cracks or cracked parts。
