Common Malfunctions and Solutions for Computerized Car Wash Machines
Mechanical equipment will inevitably experience malfunctions during use. When a malfunction occurs, the cause should be identified and resolved promptly.
If the foam system of a computerized car wash machine produces unsatisfactory foam, the problem may lie with the foam system itself. Common causes include: excessively high or low air pressure (adjusting the air pressure device to maintain normal pressure); excessively high or low foam solvent concentration (adjusting the detergent concentration); and leaks in the foam piping (perhaps due to looseness or instability). Carefully inspect and secure the leaking parts.
When the high-pressure unit of the car wash machine experiences low water pressure, it may be due to an insufficient pressure regulating valve. Adjusting the pressure to the normal value will resolve the issue. Belt slippage can also cause low water pressure; adjusting the belt tension ensures it does not slip during operation. Pipe leaks and damaged valves are also causes of low water pressure. Pipe leaks can be checked and tightened, while damaged valves require repair or replacement if repair is not possible.
Besides low water pressure, the high-pressure unit may also exhibit abnormal pump noise. Abnormal noise from the pump may be due to air intake. In this case, check the water tank level. If it’s not a low water level issue, the inlet filter may be clogged, requiring cleaning. Deteriorated lubricating oil may also cause noise; replace it immediately. Damage to valves or the pump body can also cause abnormal noise, requiring repair or replacement.
Slippage of the wheels in a computerized car wash machine may be caused by sand or gravel on the rails; clean it immediately. Abnormal noise from the wheels may indicate damaged bearings, requiring replacement. Impact vibration in the wheels may be caused by a chain that is too loose or too tight, requiring chain tension adjustment.
If the rotator at the end of the computerized car wash machine’s piping stops rotating, the main causes are clogged nozzles, excessive or insufficient nozzle deflection angles, or a damaged rotator. Solutions include cleaning the nozzles, adjusting the deflection angle to the normal value, and replacing the damaged rotator.
