Clean room centrifugal fan installation process and precautions Mar 31, 2018

In the process of installation, the clean room centrifugal fan will be directly placed on the foundation and leveled with diagonal horns. The centrifugal fan assembled on site and the cutting surface on the base of the centrifugal fan in the clean room shall be properly protected and shall not be corroded. Or operate, when the base is placed on the foundation, apply a pair of diagonal horn leveling.

The clean room centrifugal fan bearing and the base should be tightly connected, in the process of operation in the longitudinal non-level should not exceed 0.2/1000, measured with a spirit level on the spindle, the horizontal non-horizontal bottom should not exceed 0.3/1000, Use a spirit level to measure in the horizontal plane of the housing.

Centrifugal blower of the clean room centrifugal fan should effectively correct the rotor shaft line and the housing axis before grinding and scraping. When operating, adjust the gap between the impeller and the air inlet, and the main shaft and the housing rear plate. The gap between the shaft holes, so that it can meet the requirements of the equipment's technical documentation.

During the process of assembly of the spindle and paddle shaft of a centrifugal fan in a clean room, it shall be effectively inspected in accordance with the provisions of its equipment technical documents. The interference between the bearing cap and the bearing shell shall be maintained in the range of 0.03 to 0.04 mm (measured bearing diameter and bearing The inner diameter of the seat).

When the fan casing of the clean room centrifugal fan is assembled, the position of the corrector shall be determined on the basis of the axis of the rotor during operation, and the axial and radial clearances between the inlet of the impeller and the inlet of the casing shall be as high as Within the scope specified in the technical documentation of the equipment, check also that the anchor bolts are tight.
