NSRH Roots Blower Installation Precautions: Detailed Explanation

I. Foundation and Positioning

The NSRH Roots blower must be installed on a level and stable concrete foundation. The foundation strength must meet design requirements (e.g., C30 or higher), with a surface flatness error of ≤2mm/m. The foundation should be raised 10-25cm above the ground level to prevent water accumulation or vibration transmission. The installation location must be away from flammable and explosive areas, avoid corrosive gas environments, and simultaneously reserve a maintenance access of not less than 2 meters to ensure operational space.

II. Equipment Alignment and Leveling Adjustment

The blower and motor must be aligned via coupling or pulley, with radial/axial error ≤0.05mm. Use a dial indicator to measure at the 0°, 90°, 180°, and 270° positions to ensure uniform deviation. Leveling adjustment requires a precision level, with an error ≤0.2/1000, to avoid impeller friction or gear wear caused by tilting. If belt drive is used, ensure the centerlines of the two pulleys are in the same plane, and the belt tension should allow for a 10-15mm depression when pressing the middle of the belt.

III. Pipeline and Accessory Installation

Pipelines must be independently supported, avoiding direct weight on the blower. Inlet and outlet pipelines should be equipped with rubber flexible connections to reduce vibration transmission and stress impact. The installation sequence is: Blower outlet → Flexible connection → Check valve → Silencer → Valve → Pressure gauge → Main pipeline. The relief valve's set pressure should be adjusted to 1.05-1.1 times the rated pressure. Pressure gauges must be installed vertically with the gauge head facing upwards, and the rubber cap on the gauge head must be pierced before installation to equalize air pressure.
