(2) Impellers of high temperature resistant alloyed steel are optional for the high temperature boilers.
4.The following points should be paid attention to durning the process of installation:
(1) Smear some graese or machine oil on some junction surfaces in order to prevent rusting, and reduce the
difficulties when moved.
(2) When fixing the scew bolts on the junction surfaces,if there are Positioning pins,fix the Positioning pins first
then the screw blots.
(3) Check the inside of the chasssis and other cases to make sure that no tools and other substances are left in it .
5.The requirements of insallation:
(1) Install the fan according to the positiong and size indicated in the fifure.Pay a special attention to the dimension
of the gap between the inlet port and centrifugal impeller to get high efficiency.
(2) Make sure that the spidle is in horizontal position.Measure the concentricity of the spindle and motor axle.
(3) When to install the adjusting valve,do not put it reversely .Keep the inlet direction in step with the running
direction of centrifugal impellers.
(4) After the installion,move the rotor with hand or a lvver to check whether the motor is too tight or bump the
(5) Do not put any weight on the fan chasssis when to install the pipes and outlet of the fan.
(6) Examine thoroughtly to see whether it meets the requirements after installed,then carry on the testing.
