Use, maintenance and care of sterilizer

1. **Design and Manufacturing Standards for Equipment**

- The equipment is designed and manufactured according to the following standards:

- **Steel Pressure Vessels (GB150-1998)** and **Technical Supervision Regulations for Safety of Pressure Vessels (99 Edition)** for manufacturing, testing, and acceptance.

- Welding is performed according to **Welding Regulations for Steel Pressure Vessels (JB/T4709-2000)**.

- Radiographic inspection adheres to Level III of **JB4730-94**.

2. **Safety Operating Procedures for the Sterilizer**

- Users must establish and strictly follow safety procedures based on the sterilizer's technical performance and sterilization conditions. These procedures should include:

1. Operating process indicators, maximum working pressure, and temperature.

2. Methods, procedures, and precautions for operating the sterilizer.

3. Key inspection items, potential abnormal phenomena, and preventive measures during operation.

4. Maintenance protocols for when the equipment is not in use.

3. **Prohibited Operations**

- The sterilizer must not be operated at pressures or temperatures exceeding the design limits.

4. **Operator Training and Responsibilities**

- Operators must complete training and pass an examination before using the sterilizer.

- They must strictly follow safety procedures and job responsibilities, addressing any abnormalities promptly.

5. **Safety Accessories and Maintenance**

- The sterilizer is equipped with safety valves, pressure gauges, and thermometers that must remain in safe, sensitive, and reliable condition.

- Safety valves must not be adjusted arbitrarily and should trip at the design pressure.

- Pressure gauges and thermometers must meet accuracy standards (1.5 level).

- Faulty gauges or thermometers (e.g., unclear scales, cracks, or calibration issues) must be replaced immediately.

6. **Inspection and Calibration**

- Regular inspections are required:

- External inspections every six months.

- Comprehensive inspections annually, following relevant regulations.

- Inspection reports must be documented.

7. **Lubrication and Maintenance**

- Sliding and rolling contact areas (e.g., self-locking wedges, rollers, and flanges) must be regularly greased and oiled to ensure proper lubrication.

8. **Sealing Ring Replacement**

- Damaged or worn sealing rings on the pot body flange must be replaced promptly to maintain a tight seal and prevent leakage.

9. **Storage and Cleaning**

- When not in use, clean the interior and exterior surfaces thoroughly.

- Apply anti-rust paint to exposed surfaces and protect safety instruments with covers.
