From 2008 to 2010, Chinese color sorter manufacturers successfully opened up new areas, such as peanuts, black beans, white beans, tea, small yellow rice, raisins, plastics, dehydrated vegetables, coffee beans, white melon seeds, sesame, Chinese pepper, wolfberry Color selection technology for a series of crops and cash crops such as seeds and seeds. When these new fields and new demands open up the market, the development space of the color sorting industry has become infinitely broad. After the development of new fields, domestic color sorting machine manufacturers, especially the first-line manufacturers with R&D capabilities in China, realize differentiated development strategies based on their core technologies and enter different fields. For example, some color sorting manufacturers focus on small yellow rice. , Tea, white melon seeds; some color sorting manufacturers focus on peanuts, black beans, white beans, coffee beans; some manufacturers focus on plastics, etc., to further subdivide the market.
However, with the increasingly broad application market of color sorters, users are also encountering more and more problems in the processing and production of color sorters. The machine broke down and the production line stalled. The boss rushed to call the after-sales service, but after all, it took time for the after-sales service to arrive at the scene. The fastest solution is to make a preliminary diagnosis by yourself. If you can solve the problem by yourself, the impact will be minimized. As the saying goes, teaching them to fish is worse than teaching them to fish. To sum up, there are ten major machine failures. Growking Optoelectronic will help you one by one:
Common fault 1: solenoid valve leaks
Cause of failure: Dust in the valve; damage to the solenoid valve
Treatment method: repeatedly test the valve; replace the solenoid valve
Common fault 2: The solenoid valve does not operate
Cause of failure: poor contact between the plug behind the valve and the socket; the spool is disconnected; the color selection board is damaged
Treatment method: re-plug, repair the poor contact position; replace the solenoid valve; replace the color selection board
Common fault 3: Solenoid valve jet volume is small
Cause of failure: Dust in the solenoid valve; air pressure is too low
Treatment method: repeated high frequency test of solenoid valve; check pressure gauge and related gas circuit
Common failure 4: Material splash
Cause of failure: The temperature difference between the material and the trough is too large; the trough dust is agglomerated; the trough has scratches
Treatment method: adjust the temperature of the trough to be roughly the same as the temperature of the material; clean the trough with a soft cloth material; polish with fine sandpaper or replace the trough
Common fault 5: frequent solenoid valve action
The reason for the failure: the color selection method is not selected; the position of the background board is not set
Processing method: Correctly select the color selection mode; re-adjust the background board
Common fault 6: The whole machine is basically not color-selected
Cause of failure: Sensitivity is too low; solenoid valve power is not turned on
Treatment method: readjust the sensitivity; turn on the solenoid valve power
Common fault 7: Color sorting quality is getting worse and worse
Cause of failure: Dust on the glass of the sorting box; the dust removal of the color sorter is not clean
Treatment method: manual dust removal or use a soft cloth to wipe the dust on it; check the dust removal device or replace the rubber strip
Common fault 8: The single-side sorting effect of the whole machine is poor
Cause of failure: Inadequate cleaning of rodless cylinder and poor cleaning effect
Treatment method: adjust the dust scraper and the dust scraping speed
Common fault 9: The color sorter often shuts down
Reasons for failure: too high sensitivity; improper adjustment of the background board; too much impurity content in raw materials; insufficient air supply pressure of the color sorter; air pressure protection often occurs
Processing method: readjust the sensitivity; readjust the background board; reduce the output; check the air pressure; readjust if the air path is too far; clean or replace the filter element to make the pipeline unobstructed
Common failure 10: Air compressor failure
The cause of the fault: the three-phase winding of the motor is damaged; the AC contactor is damaged or poor contact; the thermal relay is damaged or poorly connected; the 380v power supply lacks phase; the three-phase voltage is unbalanced; the control switch circuit is damaged or abnormal.
Treatment method: replace the motor; repair or replace the AC contactor; repair or replace the thermal relay; repair the power supply line; adjust the transformer to balance the three-phase power supply; check the control switch and wiring.
