Equipment cleaning and inspection:

A. When cleaning and inspecting the centrifugal assembly ventilator, the casing and bearing box should be dismantled, and the rotor, bearing box and bearing should be cleaned; However, the fan with direct transmission of impeller and motor can not be removed. The regulating mechanism should be clean and flexible.

B. The axial flow assembly ventilator should check whether the root of the blade is damaged, the fastening nut should not be loose, and the installation Angle of the adjustable blade should meet the requirements of the equipment technical documents. The vertical unit should clean the transmission, gear pair or worm gear pair.

Installation of vibration isolator:

A. There are two ways to install the fan directly on the foundation and on the vibration isolation device. Vibration isolator installation, in addition to the requirements of the ground level, should pay attention to each group of vibration isolators to bear the load of the compression should be uniform, not eccentric.

B. Protective measures should be taken after installation to prevent damage. If the force of each isolator is still uneven after installation, it should be moved to the appropriate position according to the actual situation.

C. The commonly used vibration isolators include spring vibration isolators and rubber vibration isolators, and their specifications, models and performance parameters should meet the design requirements. The installation method should refer to the product sample and general atlas.
