1. **High-pressure Homogenizer Installation and Usage**
**Installation:**
- Place the machine on a flat, solid foundation.
- Adjust the four legs for leveling, using rubber anti-vibration pads under the gaskets to reduce noise and improve stability.
- Level the machine with a level ruler to ensure proper performance.
- Connect the machine to clean cooling water.
- Position the liquid tank above the feed port and the storage tank close to the machine.
- Avoid installing valves on the outlet pipe to prevent blockages and malfunctions.
**Usage:**
1. **Preparation Before Starting:**
- Wipe off protective grease from all parts.
- Tighten screws and nuts on the transmission and pump body.
- Manually turn the pulley to check for blockages or looseness.
- Fill the transmission box with clean engine oil (HJ40 or HJ50, depending on temperature).
- Set the pressure regulating handle to the loosest position.
- Connect cooling water to the plunger and open the feed pipe valve.
- Check the motor direction; the large pulley should rotate clockwise.
2. **Starting the Machine:**
- Start the motor and run it lightly.
- Loosen the bleed screw to remove air from the feed pipe and pump body.
- Gradually adjust the homogenizer handle to reach the required pressure, monitoring the pressure gauge and ammeter for synchronization.
- For a two-stage homogenizer, set the first-stage pressure to 2/3 of the required value, then adjust the second stage to the desired pressure.
- Avoid exceeding 110% of the rated pressure during operation.
- Filter the liquid through a 25-mesh wire mesh to prevent blockages.
- Monitor bearing temperature, oil levels, noise, and pressure changes during operation.
3. **Stopping the Machine:**
- Loosen the homogenizer pressure handle to release pressure before stopping.
- Close the feed pipe valve after shutdown.
- Clean the pump immediately using a suitable cleaning solution to prevent residue buildup.
4. **Precautions:**
- Do not start the machine under pressure.
- Ensure sufficient lubricating oil; the oil level should not fall below the minimum line.
- Operate the machine clockwise (facing the large pulley).
- Inspect and tighten screws after initial use and replace oil after the first week.
- Check the pressure gauge holder for oil if the gauge malfunctions.
- Tighten the drive belt periodically after extended use.
2. **Reactor Processing and Cleaning Guidelines**
**Processing Guidelines:**
- Follow design drawings and technical requirements strictly.
- Inspect borrowed tools and reactor blanks before processing.
- Perform first-piece inspections in a free-standing state and after tool changes.
- Divide continuous processes into steps for self-inspection and quality checks.
- Deepen or remove chamfers and undercuts as needed.
- Keep workpieces clean and rust-free after processing.
- Use magnetic tables for holding workpieces and demagnetize them afterward.
- Ensure all surfaces meet dimensional and form tolerance requirements.
- Maintain a clean and organized workplace.
**Cleaning Sticky Reactors:**
- **For Stainless Steel Reactors:**
- Use a pickling solution (81% formic acid, 17% water, 1.2% buffer, 0.8% surfactant) at 60°C.
- Perform static immersion for 2 hours, followed by 3-4 hours of dynamic circulation.
- Passivate the reactor after cleaning to prevent corrosion.
- Flush the jacket to remove impurities before pickling.
- Rinse thoroughly with clean water after alkaline cleaning.
- Record all cleaning steps for verification.
By adhering to these guidelines, both the homogenizer and reactor can be operated and maintained effectively to ensure optimal performance and longevity.
