How to solve the problem of multi-function fruit and vegetable washing machine failure? And how to do maintenance work in daily use.
Multi-function fruit and vegetable washing machine common fault solution
1, insurance damage
If there is no power display after booting, no action, first of all, it depends on whether the insurance in the power socket is damaged.
Analysis and judgment: It is possible that the user grounding wire is mixed with the live wire or the neutral wire, and there is no grounding (the ground wire of the machine is connected to the outer casing of the machine), and there may be a short circuit of the machine, and a short circuit occurs in the aging of the components, resulting in insurance damage. .
Detection and solution: Take out the fuse and see if there is any break. Use the multimeter to measure the disconnection and replace it with a new one.
2, the transducer is damaged
Analysis and judgment: It may be due to the long-term use state, the temperature will gradually rise, causing the alternating melted words to fall off or the ceramic part to break.
Ultrasonic transducer
Ultrasonic transducer
Detection and solution: The insulation strength of the words can be measured with a shaker. The insulation strength is below 200M, which is no longer usable and requires a new transducer. Because the internal ceramic of the transducer will also break due to long-term use, it will not work properly.
3, power tube damage
Analysis and judgment: The power tube on the main board will be used continuously for a long time, or the cleaning liquid will be used for too long, and the power tube will be short-circuited.
Detection and solution: When the power tube is connected on the main board, measure the resistance of the pins on both sides of the power tube with a multimeter. Under normal circumstances, it should be around 22, after taking down the power tube (disconnected from the main board), measure each of them. There should be no connection between the pins.
Maintenance of multifunctional fruit and vegetable washing machine :
1. Belt adjustment: In the middle of the two pulleys, the compression of the belt (middle finger and index finger) is 7-12MM as the standard value. When the value is greater than the standard value, adjust the idler to the specified tightness. The chain is pressed by the fingers (middle finger and index finger) in the middle of the two sprockets, and the compression amount is 4-9MM as a standard value. When the standard value is exceeded, adjust the idler to a fixed tightness.
2, multi-function fruit and vegetable washing machine stepless gearbox oil refueling and replacement: the first is to stop the motor, the fire is not allowed to remove the oil plug, the oil just out of the appropriate amount, when it is insufficient to supplement.
3, the multi-functional fruit and vegetable washing machine temporarily does not need to be placed for a long time:
When we want to save for a long time without using it, we can clean and clean all parts of the earth, etc., and all the rotating parts and the attached objects such as belts and chains should be completely removed and the turning parts And rub the active part, fully oiled to prevent the occurrence of rust.
If you do not use the storage for a long time, when we want to save for a long time without using it, we can rinse all the parts of the soil, etc., and the attached parts of the rotating parts and belts and chains must be completely clean. The cleaning and the rotating parts of the rotating parts are fully filled with oil to prevent the occurrence of rust.
The above is the solution to the common faults of the multi-function fruit and vegetable washing machine and daily maintenance.
