Dust removal fan impeller installation without heating? My colleagues will be heated when installed, but I always feel the heat of the impeller, the shaft will follow the heat, will be installed on the half of the installation will not go in. Then there is no good tool or good way to install the impeller? I hope people with experience can give advice.
Cold installation, hot loading can be. If it is cold, according to the standard operation, that is, use "press" to direct the impeller to the shaft. But you need to control the hot charging temperature, shaft, impeller hub is the general stress relieving treatment, therefore, can not be deformed below 400 DEG below, that is to say, to the hub heating must not higher than 200 DEG C.
3, after fan installed by hand or lever pull impeller, check whether there is tight or rubbing, have hindered rotation of the goods, no abnormal phenomenon, can test run, exposed parts of fan drive should cover (optional), the air inlet is not connected wind pipe machine when, also need to purchase protective network or other safety devices (optional).4, fan wiring must be correct and reliable, fan housing should be properly grounded, grounding must be reliable. The power supply of the blower must be complete and comply with the relevant requirements. Fan wiring must have professional knowledge of electrical wiring.5, fan installed after all, should check whether there are remnants of fan internal tools and debris.
Dust collector fan installation should do the following1, fully familiar with the fan with fan samples, specifications, types, the direction of impeller rotation direction of air inlet and outlet, and so on; fan before installation should check the impeller with and without rubbing, and to conduct a comprehensive inspection of the components, the attachment is complete, each component connection is fastened. Check whether the blade has been damaged or deformed due to transportation, otherwise it should be installed before it can be repaired.2, connecting the fan inlet and outlet duct should be supported, not allowed to add the weight of pipes fan parts; fan installation should pay attention to the horizontal position of the fan, with the fan and the ground surface and a connecting duct should be adjusted to fit the nature, not strong line connection.
