He aha te mea e tika ana kia whai whakaaro koe i te wa e whakauru ana i nga paahitanga axial flow

Hei whakarei ake i te hoahoa me te mahi a nga kaiwhaiwhai axial pahū, whakaarohia nga aratohu whakaurunga e whai ake nei:

1. Inspect the fan for any physical damage or deformation before installation and verify that the supply voltage falls within the specified range. Whakaritea te ngaohiko ina tika i mua i te haere ki te oma whakamatautau.

2. Ensure all connections are secure and the gaps between the blades and air duct are uniform. A collector must be fitted at the fan’s intake, and the base should naturally align and level with the ground before securing with bolts.

3. Verify the fan’s whakapapa whenua.

4. Prior to the test run, momentarily activate the power to confirm the alignment of the fan with the directional arrows on the casing. Adjust the power phase if needed.

5. To maintain optimal performance as per the performance curve, ensure no obstructions during the test run, keeping both the intake and exhaust clear. Blockages can reduce airflow and, i nga keehi kino, cause surging.

6. Monitor the balance of the three-phase current and listen for any unusual noises from the motor, whakahihiri, or transmission components during commissioning. Immediately halt operations and cut power if any abnormalities are detected, diagnose the issue, address the fault, and only then continue operations.
