Introduction
A steam sterilizer, also known as an autoclave, is a vital sterilization device that uses pressurized saturated steam to eliminate microorganisms on medical instruments, laboratory tools, and agricultural materials. It ensures rapid, reliable, and non-toxic sterilization, widely applied in healthcare, laboratories, and agriculture.
Depending on size and structure, steam sterilizers can be classified into:
Portable steam sterilizers
Vertical steam sterilizers
Horizontal steam sterilizers

Importance of Preventive Maintenance
To ensure long-term stable operation and avoid unexpected downtime, preventive maintenance is essential. It involves routine inspection, cleaning, lubrication, and minor repairs to maintain optimum performance. This process includes both daily maintenance and scheduled preventive overhaul.
1. Daily Maintenance Tasks
Daily maintenance mainly involves basic upkeep to keep the equipment in good condition:
Check the door/lid and rubber gasket for wear, cracks, or deformation
Inspect the pressure gauge for normal readings
Verify the status of pipes and valves for leakage or blockage
Clean the inner chamber filter daily to prevent residue buildup
Lubricate moving parts weekly and conduct a deeper clean monthly
This helps to ensure sealing effectiveness, temperature consistency, and pressure safety.
2. Preventive Overhaul (Monthly)
Preventive overhaul should be conducted by qualified maintenance technicians and includes:
Routine inspection of internal pipelines, steam outlets, and valves
Replacement of any worn-out gaskets, gauges, or valves
Calibration of sensors and intelligent controllers
Keeping a detailed maintenance log: date, device serial number, fault description, replaced components
This ensures the steam sterilizer runs efficiently and extends the service life of the system.
3. Intelligent Control Systems
Modern autoclaves, like those offered by Nanbei Instruments, are equipped with automatic intelligent control systems that:
Automatically monitor cold air exhaust
Maintain pure saturated steam conditions
Provide real-time pressure and temperature control
Offer fully automatic cycles for sterilization, drying, and cooling
These features not only reduce manual intervention but also improve sterilization efficiency and safety.
