Stainless steel reactor magnetic drive mixer

### Magnetic Drive Mixer for Stainless Steel Reactors

The stainless steel reactor magnetic drive mixer employs a **static seal** principle, ensuring **zero leakage** by using magnetic force to transmit torque and energy. Key features include:

1. **Power:** High-quality magnetic steel and a torque safety factor of 1.5 ensure strong and stable operation.

2. **Shock Resistance:** A magnetic protection structure prevents damage during high-speed operation.

3. **High-Temperature Resistance:** A water cooling system prevents demagnetization in high-temperature environments.

4. **Energy Efficiency:** Axial flow impellers optimize fluid dynamics for energy-saving performance.

5. **Double Sealing:** Combines magnetic drive and sealing technology for enhanced reliability and reduced maintenance costs.

6. **Corrosion Resistance:** Materials like 304/316 stainless steel, titanium, and PTFE treatments meet diverse corrosion protection needs.

### Cleaning Scale or Sticky Residues in Reactors

For reactors affected by scale or sticky materials:

- **Stainless Steel Reactors:** Acid cleaning is effective if neutralized properly. Key steps include:

1. **Pickling Temperature:** Optimal at 60°C to balance descaling and prevent corrosion.

2. **Pickling Solution:** Use a solution of 81.0% formic acid, 17.0% water, 1.2% buffer, and 0.8% surfactant.

3. **Method:** Perform static immersion for 2 hours, followed by 3–4 hours of dynamic circulation.

4. **Passivation:** Treat the equipment after pickling to protect exposed metal surfaces.

5. **Flushing and Neutralization:** Rinse with clean water and neutralize any residual acid.

### Maintenance and Operation Guidelines

1. **Reducer Oil:**

- Use 40#–50# engine oil or 70#–90# industrial turbine oil.

- Replace oil after the first 60 days of operation, then every 6 months.

2. **Condenser Maintenance:**

- Monitor heat exchange performance to determine if pipes need cleaning.

3. **Load Limits:**

- Do not exceed the effective volume of the mixing tank to prevent motor burnout or component damage.

4. **Extended Downtime:**

- Clean, lubricate, and disconnect power for prolonged inactivity.

By adhering to these practices, the stainless steel reactor can maintain efficiency, reliability, and longevity.
