1. Choosing a location for the air compressor room:
- The compressor room should be in a cool, clean, and well-ventilated space, with the environment temperature between 0°C and 40°C.
- The room should have lifting equipment like cranes or forklifts for maintenance access.
- Avoid outdoor installation to protect the compressor from rain, direct sunlight, and excess dust.
- Ensure the room is not too small and poorly ventilated to prevent high exhaust temperatures.
- Avoid dusty environments, especially near sandblasting equipment, to prevent wear.
- Keep the compressor away from areas with flammable gases, corrosive chemicals, or high humidity to avoid explosions or rust.
2. Layout of the compressor room and compressor placement:
- Install an air tank after the compressor with a capacity 20% greater than the compressor’s air output and ensure regular drainage.
- Place the air tank before the dryer if installed to allow cooling and buffering of the compressed air.
- Place the compressor on a flat, stable surface like concrete without the need for shock pads unless specified.
- Ensure at least 1.5 meters of clearance around the compressor for maintenance.
3. Air compressor pipe connections:
Exhaust pipe connection: a. The exhaust pipe should connect from above to prevent condensation backflow.
b. Ensure the pipe diameter matches or exceeds the exhaust port.
c. Install a ball valve for isolation; no need for a check valve.Cooling water connections for water-cooled compressors: a. Install a 40-mesh water filter in the cooling water inlet.
b. Ball valves must be installed between the water pipes and the compressor, with a drain valve for winter use.
c. Install pressure and temperature gauges on water pipes.
4. Cooling water requirements for water-cooled compressors:
- Maintain water pressure between 0.3-0.5 MPa with at least 0.15 MPa pressure differential.
- Keep water temperature below 35°C, using a cooling tower if necessary.
- Adjust water flow based on compressor power.
- Ensure water quality:
a. pH: 6.8 to 8
b. Total dissolved solids: < 450 mg/L
c. Hardness (as CaCO3): < 300 mg/L
d. Suspended solids: < 50 mg/L
e. Chlorides (Cl-): < 150 mg/L
5. Compressor ventilation:
- If the compressor power is low and the room is large, install exhaust fans high up to remove heat.
- For larger units, ductwork can be used to expel hot air outside. Keep ducting the same size as the compressor vent.
- If the duct length exceeds 5 meters or if the room remains hot, install an extractor fan.
6. Main electrical cable installation:
- Refer to the user manual for low-voltage cable specifications.
- Install fuses and isolation switches near the compressor for easy access.
- For high-voltage cables, follow national standards and design by certified professionals.
- Ensure the compressor motor shell is grounded with a separate grounding wire.
- Avoid stress on cables to prevent loosening and short circuits.
- Keep cables away from sharp metal edges to avoid damage.
