High pressure dc blower low noise blower high efficiency blower industrial blower fans regenerative air blower

Installation, commissioning and operation
1. Before installation:

All the components of the fan should be comprehensively inspected, such as: whether the mechanical parts are complete, whether the rotation direction of the impeller and the casing is consistent, whether the connection of each part is close, whether the main mechanical parts such as the impeller, spindle, bearing are damaged, and whether the transmission group is flexible, etc., if the problem is found, it should be repaired immediately.

2. When installing:

Pay attention to check the casing, there should be no tools or debris dropped and left in the shell. In order to prevent rust and reduce disassembly difficulties, a layer of lubricating oil or mechanical oil should be coated on some bonding surfaces. The connection surface between the fan and the foundation and the inlet and exit pipelines should be adjusted to make them coincide naturally. The connection should not be forced, and the weight of the pipeline should not be added to the components of the fan, and attention should be paid to ensure the horizontal position.

3. Installation requirements:

(1) Install according to the position and size shown in the drawing. In order to ensure high efficiency, especially ensure the axial and radial clearance size of the air inlet and the impeller.

(2) After installation, try to dial the transmission group to check whether there is too tight or scratches with the fixed part. If not, it should be excluded.

(3) Test operation of fan:

After all installation is completed, the test run can only be carried out after the general inspection is qualified.

The power selected by the fan refers to the specific working condition, coupled with mechanical loss and the due safety factor, in order to prevent the motor from being burned due to overload, the fan must be started and tested in the absence of load, namely: Will go to adjust the door closed, wind the wind door slightly open for tuning section, such as no vibration, peculiar smell, sound, and the abnormal phenomenon such as leakage, leakage, leakage, then step by open gate, to the provisions of the conditions, in the process of operation should strictly control current, shall not exceed bid, bearing temperature rise Shall not be more than 40 oc, temperature is not more than 70 c.
