Installation and maintenance of FRP exhaust fan

   FRP blower The glass fan (FRP) material has the same appearance and size as the steel fan. The FRP fan is only made of FRP material with its outer shell and impeller. Its biggest feature is corrosion resistance, acid and alkali resistance, and belongs to a kind of anticorrosive fan. FRP roof fan series: FRP fan DWT-I type fiberglass axial flow roof fan, DWT-II FRP centrifugal roof fan, DWT-III FRP centrifugal roof fan, BDW-87-3 FRP low noise roof fan, WS-85-6 type FRP roof fan, BDW-87-4 FRP centrifugal roof fan, YDTW type FRP roof fan, WT35-11 FRP shaft Roof fan. Bearing and fan impeller, in the use of the role can not be ignored, but there are always many problems in the use of bearings, some of the bearing failures are actually many small details accumulated over the years, such as the fan bearing wear problem, Wen Sheng problem, etc., these problems will affect the bearing's effect, so solve these problems is to use. At present, the more important thing is how to raise the bearing temperature. Let's first find out the reasons why the bearing temperature is too high.

The relationship between the lubrication system and the bearing is very close. The purpose of our fan lubrication is to make friction between the solid part and the liquid part without any direct contact between the moving parts and the static parts. If the quantity of lubricating oil is insufficient or the quality is not good, it will cause direct friction and heat of the moving part, or the heat can not be carried away by lubricating oil, and the temperature of the bearing of the high pressure fan will be raised. Therefore, users must pay attention to the lubrication system of the fans and protect them as far as possible.


FRP Exhaust fan FRP axial fan series: FT35-11 type fiberglass axial flow fan, FZ40/35 textile glass fibre reinforced plastic axial flow fan, CDZ series ultra-low noise FRP axial flow fan, DFBZ type square wall glass steel axial flow fan, SF series energy-saving low noise FRP axial flow fan, GD30K2-12 type glass fiber reinforced plastic axial flow fan, WEXD glass fiber reinforced plastic side wall fan.


FRP centrifugal fan series: F4-72 type FRP centrifugal fan, F9-19 High Pressure FRP centrifugal fan, F9-26 High Pressure FRP centrifugal fan.


Glass fiber reinforced plastic oblique flow fan series: FSJG series pipeline type glass fiber reinforced plastic oblique flow fan and so on.


1. Improper mechanical installation, misalignment of parts and heavy load.


2, the shaft alignment is bad.


3, machine geometry parameters (such as fit clearance, interference and relative position) are not properly adjusted.


4. The stress of the pipeline is large. The machine changes its dynamic characteristics and installation accuracy under working condition.


5. Improper placement of the rotor for a long time has changed the accuracy of the dynamic balance, failing to repair it according to the regulations, which has destroyed the original matching properties and accuracy of the machine.
