How to Ensure the Normal Operation of a Steam Sterilizer

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.
