After-sales service
During the warranty period, a dedicated person will be assigned to be responsible for maintenance. If any equipment failure occurs, a response should be made within 2 hours. Professional technicians will be sent to the site for maintenance in the shortest possible time and the problem will be solved within 24 hours. If the failure cannot be eliminated on time, a spare product should be provided so that the tenderer can use it normally.
If the fault is not resolved within 24 hours, the tenderer has the right to handle the fault on its own, and the cost will be deducted from the quality warranty. In the event of an emergency repair accident, we will ensure that we arrive at the scene of the accident immediately after receiving the notice.
Service commitment outside the warranty period: After the quality assurance period, we also provide free telephone consultation services and promise to provide on-site maintenance services for products; if the tenderer has needs for product upgrades, updates, replacements, repairs, etc., we promise to provide after-sales services 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 |
