Tubular sterilizer precautions

To ensure the proper operation and maintenance of a tubular sterilizer, follow these precautions:

1. **Steam System**: Regularly inspect the steam trap and filter to prevent condensate blockages.

2. **Safety Checks**: Regularly check the safety valve, pressure gauge, and thermometer for proper function.

3. **Pump Maintenance**: Repair or replace the feed pump shaft seal if severe leakage occurs.

4. **High-Pressure Pump**: When used with a high-pressure homogenizer, ensure the 3WR-1.5 high-pressure pump is maintained per the manual.

5. **Freezing Protection**: In freezing conditions, drain water from the pipes or fill them with a 1% alkali solution.

6. **Sealing**: Regularly inspect material joints and stopcocks to prevent leaks and air intrusion, which can accelerate scaling.

7. **Steam Exhaust**: Keep the steam exhaust valve open when the equipment is not in use.

8. **Lubrication**: Clean and lubricate the motor bearings of the feed centrifugal pump annually, filling the bearing housing only halfway.

9. **Pump Operation**: Avoid running the feed pump without liquid.

10. **Power Outages**: During a sudden power outage, shut off the steam, open the steam exhaust valve, and drain the steam from the high-temperature drum while opening the water inlet shut-off valve.

11. **Circulation**: If steam is shut off or pressure is insufficient, adjust valves to allow material circulation or temporarily shut down the sterilizer.

12. **Debris Prevention**: Prevent debris from entering the sterilizer to avoid clogging and scaling of the coils.

13. **Preparation for Reuse**: Open the angle shutoff valve and steam drain valve when the equipment is not in use to prepare for the next operation.
