Regenerative Dryer Maintenance Guide
Daily maintenance content, monthly maintenance content, quarterly maintenance content, annual maintenance content
Daily maintenance content:
Precautions
1. Check the automatic drain valve on the pre-filter before each shift every day.
2. Check if the operation of changing towers, regeneration and boosting is normal.
3. Check operating conditions, inlet pressure, inlet temperature and air flow.
4. Check the moisture indicator, blue for dryness and pink for wet.
5. Check if the muffler is dirty. If the regenerative tower back pressure is too large, the muffler needs to be replaced.
6. Check the pre-filter and post-filter pressure drop. If the pressure drop exceeds 0.5 bar, replace the filter element.
Monthly maintenance content:
1. Check the control air filter of the heatless and hot regenerative dryer. Replace if necessary.
2. Check the filter element of the blast dryer guide filter and replace if necessary.
3. Check the suction filter of the blower dryer and replace if necessary.
Quarterly maintenance content:
1. Inspect the front and rear filter cores to check for blockages and possible damage and replace as needed.
2. Purge the safety valve with compressed air.
3. Check the dew point status of the output.
Annual maintenance content:
1. Close the shut-off valve connecting the inlet/outlet of the dryer, completely open the bypass line, thoroughly depressurize the dryer system, open the desiccant filling port, sample and check the desiccant, if the desiccant is contaminated and crushed by oil, please replace Desiccant.
2. Remove and inspect the outlet check valve. Repair and replace as appropriate.
3. Remove and inspect the imported pneumatic valve and regenerative exhaust valve to clean and replace worn seat and seals.
4. Check the pneumatic valve cylinder for leaks or seals for wear.
5. Repair check the boost valve.
6. Maintenance inspection and control of the pneumatic solenoid valve.
7. Calibrate the dew point probe (if equipped with a dew point meter).
8. Check if the muffler is blocked by oil or dust. The back pressure should be replaced if it exceeds 0.35 bar.
