After-sales service
During the warranty period, arrange for a designated person to be responsible for maintenance, and respond within 2 hours if the equipment fails. Send professional and technical personnel to the site for maintenance in the shortest possible time, and resolve the issue within 24 hours.
If the fault is not resolved within 24 hours, the bidding party has the right to deal with the fault by itself, and the expenses incurred will be deducted from the quality warranty. In the event of an emergency repair accident, we will ensure that we arrive at the accident site immediately after receiving the notice.
Service commitment beyond the warranty period: After the quality assurance period, we will also provide free telephone consultation services and promise to provide product door-to-door maintenance services; if the bidding party has product upgrades, updates, replacements, maintenance and other needs, we promise to provide after-sales service at preferential prices.
Self-service troubleshooting
| Fault | Causes | Troubleshooting Methods |
|---|---|---|
| Sudden stop of the spindle rotation(i.e., jamming, stalling) | 1. Large - scale feeding without the press chamber being heated up | 1. Feed only after the cake comes out |
| 2. The cake residue is too dry during the running - in process | 2. Increase the moisture content of the cake residue | |
| 3. The cake thickness is too thin, causing increased pressure in the press chamber | 3. Rotate the adjusting bolt clockwise to increase the cake thickness | |
| 4. The shell - containing oil material has a high shell content or hard substances are mixed into the oil material and enter the press chamber | 4. Turn off the power, disassemble the upper press cage, loosen the press ring, pull the spindle, and clean the press chamber | |
| No feeding and no oil output | 1. The working surface of the newly replaced press screw is not smooth | 1. Use cake residue (except tea seed cake) and add water (about 10% or so), slowly add it to the press chamber for pressing, and run - in until smooth |
| 2. Accumulated oil in the press chamber, with the oil material mixed with oil | 2. Add a small amount of cake residue for pressing together. When re - feeding, start from a small quantity and increase gradually, not too aggressively | |
| 3. The oil - outlet grooves of the press bars and press rings are blocked, resulting in poor oil drainage | 3. Remove the press ring, soak the press bars in hot water for dozens of minutes, and clean with a steel wire brush | |
| 4. The oil content of the pressed oil material is too high, and the original oil - drainage channels are too few | 4. Replace the corresponding press bars and press rings | |
| 5. The moisture content of the oil material for hot pressing is too low before pressing | 5. Ensure the oil material has an appropriate moisture content before pressing |
