GUOMAT tells you the Common faults and causes of air springs
Common faults of air springs include: air spring collapse, air spring surface wear or wear, air spring upper seat plate depression, air spring upper seat plate projection.
The cause of the failure is analyzed as follows:
The air spring collapsed. Cause: The air pressure of the gas storage tank is too low to open the pressure protection valve, the air control circuit sinks or leaks, the height control valve fails or the flexible connecting rod is loose.
The surface of the air spring wears or wears through. Reason: The air spring has insufficient clearance around it, friction with its zero, damage to the shock absorber, loose piping, etc., which cause interference with the airbag. The air spring base is stuck with sand and glass slag.
The air spring is recessed on the seat plate. Reason: The suspension height is too low, the air spring works for a long time under low air pressure, the height control valve fails or its flexible connecting rod is loose, the air spring model is wrong, the air supply pressure is low, and the vehicle overload is serious.
The air spring upper plate is raised. Cause: The shock absorber is inoperative, damaged or the model is incorrect, and the height control valve does not work.
