Exhaust fan installation and maintenance: a kitchen fan is indispensable key kitchen equipment, it is recommended not to install in the ceiling as possible, to be installed in the engine room, the roof or exterior wall to facilitate maintenance of the place. Second, the kitchen fan because of long working hours in hot, humid, gas fumes. Regular maintenance is indispensable work. Point of failure: 1, the impeller blade curvature oily lead angle deformation, the air volume decreased significantly total pressure parameters, reach smoke requirements. 2, the impeller oil stains cause impeller to lose balance, increased vibration, bearing damage. 3, harsh environments parts easily rust, damage the fan. Fire temperature exhaust fan installation process: a comprehensive sample of fans familiar, familiar fan specifications, form of the impeller rotation direction and the direction of the air flow in and out, etc., you should check whether the collision phenomenon impeller fan before installation, and the various components comprehensive inspection, the attachment is complete, whether the parts join sturdy blades carefully check whether due to shipping damage or deformation, otherwise should be repaired before installation. 2, import and export of the fan duct connection should be a separate support fire temperature exhaust fan manufacturers, plus the weight of the pipe is not allowed on the blower parts, turbine installation should pay attention to the horizontal position of the fan, the fan and the foundation of the joint surface and joins the wind pipe should be adjusted to make it a natural fit, not be forced to join. 3, after the installation of fire temperature exhaust fan blower price, hand or lever Stubbs impeller, check if there are too tight or collision phenomenon exhaust fan, whether or interfere with the rotation of items, no abnormal phenomenon under fire exhaust fan parameters htf before test run, the exposed parts of the wind should have the opportunity to gear guard (user-supplied). Such as when the fan is not connected to the inlet pipe, also need to purchase protective nets or other safety devices (user-supplied). 4, the fan wiring must be accurate and reliable, the fan housing should be properly grounded, grounding must be reliable. Fan power supply must be complete and comply with the relevant requirements. Electrical wiring must have electrical wiring expertise.
