Requirement Confirmation and Evaluation

1. Determine the model, technical parameters (flow rate/pressure/power, etc.), service life, and failure records of the old equipment.
2. Evaluate the technical requirements of the new equipment to ensure performance matching or upgrade (such as energy efficiency, noise, material, etc.).
3. Develop the procurement budget and replacement schedule.

Selection and Procurement of New Equipment

1. Select new equipment based on process requirements (such as distinguishing between dry-type and oil-type vacuum pumps, selecting centrifugal or Roots-type blowers, considering corrosion resistance and explosion-proof for liquid pumps, etc.).
2. Sign the procurement contract, specifying delivery date, installation support, and after-sales service terms.

Preparation for Shutdown of Old Equipment

1. Notify relevant departments in advance of the shutdown time to ensure production plan adjustments.
2. Drain the medium of the old equipment (gas/liquid), cut off power/gas supply, and prepare for safety isolation (such as blind plate sealing).

Disassembly of Old Equipment

1. Disconnect pipe/cable connections, mark the interface locations (take photos for record).
2. Check if the foundation of the old equipment is compatible with the new equipment, and modify the foundation or pipes if necessary.
3. Safely remove the old equipment, clean up the site oil stains/residual media (especially flammable and explosive media require professional treatment).

Installation of New Equipment

1. Position the new equipment according to the drawings, correct the levelness and centrality (for blowers, strict centrality is required to avoid vibration).
2. Connect the pipes/electrical lines, ensure the sealing (for liquid pumps, test the flange sealing, for vacuum pumps, check for leaks).
3. Add lubricant or coolant (e.g., for oil impeller vacuum pumps, replace with new oil).

Single Machine Test Run

1. Test the motor direction by point operation (reversing the liquid pump will damage the impeller).
2. Check for vibration, noise, and temperature rise during no-load operation (the blower's bearing temperature should be monitored).
3. Gradually load to the rated operating conditions, record operating parameters (such as the ultimate vacuum of the vacuum pump, the head of the liquid pump, etc.).
4. Safely remove the old equipment, clean up the oil stains/residual media on the site (especially flammable and explosive media require professional treatment).

System Commissioning and Acceptance

1. Test the interconnection with upstream and downstream equipment (such as pressure maintenance test of the vacuum system, flow stability of the liquid pump).
2. Sign the acceptance report, confirm that the performance meets the standard (comparable to the energy efficiency data of the old equipment).

Disposal of Old Equipment

1. Evaluate residual value: available for spare parts, resale, or scrapping (compliance with environmental regulations is required for proper disposal).

2. Clean residual chemicals for liquid pumps, and recover lubricating oil for vacuum pumps/air blowers.

Training and Documentation Updates

1. Train operators on key points for new equipment maintenance (such as regular dust removal for dry vacuum pumps).
2. Update equipment records, operation manuals, and emergency response plans.
