Installation requirements of induced draft fan:
1. After the installation of the fan, move the rotor by hand or lever to check whether it is too tight or bumpy, and try to run without these phenomena.
2, when the outlet is installed into a certain Angle, the appropriate rotation after the plate can make the horizontal position, Angle steel flange surface №8~12 should be maintained level.
3. When installing the boiler induced draft fan, the weight of the gas pipe shall not be increased on the shell. The clearance size between the air inlet and the impeller shall be corrected according to the drawings, and the horizontal position of the shaft shall be maintained.
4. When installing the air inlet pipe, it can be directly connected with the bolt of the air inlet itself, and the air inlet is fixed with three countersunk head screws.
5, when installing the fan №8~12d, use the dial indicator and ruler to measure the coaxiality of the fan spindle and motor shaft and the non-parallelism of the two ends of the coupling. The non-parallelism tolerance of the two axes is 0 and the non-parallelism tolerance of the two ends of the 05mm coupling is 0 and 1 mm
6. After the motor is installed, install the belt pulley or coupling shield. If the air inlet is not connected to the intake pipe, a protective net or other safety device (provided by the user) will be added. Other components shall be installed according to the drawings.
How to maintain the induced draft fan bearing box?
1. Water insulation is frozen between transmission layers with the same sound. In order to ensure the abnormal use of bearings and gears, it can be foreseen that the excessive use of chilled water is water cooled storage boxes with low temperature fans.
2. If you work below 0 degrees south, you have to be careful. The difference in weather between the north and the north makes the northern storage boxes less successful. After the fan stops, there is no heat source in the storage box, and the water cools rapidly, reducing the amount of ice. If the temperature fan stops working, the chilled water must be drained from the storage tank. If only two liquid levels succeed, it's harder.
3. It can be seen from the oil window of the storage box that the oil of the storage box is milky red, but after repeated argumentation, it is preliminarily judged that the water has entered the induced draft fan.
4. Here's another scenario. Although the probability of occurrence is relatively low, past experience suggests that it is possible. The hard objects in high temperature fans are usually stones, non-metals and so on. The bearing box of the low-temperature fan must be protected from sufficient damage caused by the impact of hard objects.
5. From the point of view of oil output, the pressure caps at both ends of the bearing cannot solve the oil packet problem in principle, and are narrower after use, but simple and effective. At the same time, periodically observe the oil window, confirm the oil inventory, and fill once in a while if necessary.
