Mechanical equipment will inevitably experience malfunctions during use, and in the event of a malfunction, the cause should be promptly identified and resolved. A simple analysis of common malfunctions of automatic car washing machines in the car’s machinery.

If the foam system of the computer car washer is not ideal, it may be that there is a problem with the foam system. The main reasons for the unsatisfactory foam are: the air pressure is too high or too low, which can be solved by adjusting the air pressure device to keep the air pressure normal; If the concentration of foam solvent is too high or too low, adjust the concentration of lotion; The leakage of foam pipeline may be caused by looseness or looseness, so it shall be carefully checked and fastened.

When the high-pressure main unit of the car washing machine experiences a problem of low water pressure, it may be due to the low pressure of the pressure regulating valve. Adjusting the pressure to the normal value can solve the problem; Belt slippage can also easily result in low water pressure. Adjust the belt tension to ensure that there is no slippage during use; Pipeline leakage and valve damage are also causes of low water pressure faults. Pipeline leakage only needs to be checked and tightened, valve damage needs to be repaired, and those that cannot be repaired need to be replaced.

In addition to the malfunction of low water pressure, high-pressure hosts may also experience abnormal pump noise. The pump produces abnormal noise, which may be due to air intake. At this time, the water tank level should be checked; If it’s not a problem of low water level, it could also be that the inlet filter is clogged and the filter element needs to be cleaned; It is also possible that the lubricating oil has deteriorated and should be replaced immediately; Damage to the valve and pump body can also cause abnormal noise in the pump, requiring repair or replacement.

When the walking wheel of the computer car wash machine slips, it may be caused by sand and stones on the railway track, and it should be cleaned immediately; When there is abnormal noise from the walking wheel, it may be due to damaged bearings that need to be replaced with new ones; If there is impact vibration on the walking wheels, it may be caused by the chain being too loose or too tight, and the tension of the chain needs to be adjusted.

The pipeline terminal of the computer car washing machine has a malfunction of the rotator stopping, mainly due to nozzle blockage, nozzle deflection angle being too large or too small, and rotator damage. Solutions include cleaning the nozzle, adjusting the deflection angle to the normal value, and replacing the damaged rotator.
