Water pump bearings axial clearance adjustment should be noted

Bearing life is relationships with care and maintenance is very important, as it relates to water pump bearings the length, high and low productivity. Maintenance of good used bearing, will bring a lot of benefits, for example, can result in high productivity, produce more high quality precision products, maintenance can extend the life of your save time purchasing costs.
1 adjust the shim method:
In bearing end cover and bearing block end surface Zhijian filled put a group soft material (soft steel tablets or elastic paper) gasket; adjustment Shi, first not put gasket loaded Shang pump axis even bearing end cover, side uniform to twist tight bearing end cover Shang of screws, side with hand turned axis, until bearing scroll body and outer ring contact and axis internal no gap weizhi; then measurement bearing end cover and bearing block end surface Zhijian of gap, again plus bearing in normal work Shi by needs of axis to gap; this is by needed filled put gasket of total thickness, Then put ready gasket placed on the bearing end cover and bearing between the end and finally tighten the screws.
2 adjust the bolt method:
Pressure in the pressure ring on the bearing outer ring, with adjustment bolts pressure; pressure before adjusting, first measure the pitch adjustment bolt, then tighten adjusting bolt slowly until until there is space within the bearing and calculate the corresponding rotation angle adjustment bolt. For example, pitch is 1.5mm, required for the normal operation of the pump bearings the clearance, then the required rotation angle adjustment bolt 3600x0.15/l.5=360; flip 360 adjustment bolt, bearings, axial clearance of the 0.5mm, and then use the gaskets fixed to stop.
Flow of grease-lubricated bearing grease should be replaced after running the 1500 hours, raising to moderate the amount of oil because too much or too little can cause grease pump bearings heat, fuel generally lies in the 1/2~2/3 of bearing Chamber volume is appropriate.
However, for lubricating bearings, oil should be added to the location of the corresponding provisions;

Previous: Overhaul maintenance attention to four points of deep groove ball bearings
Next: In operation of electric spindle bearing lubrication maintenance periodically maintenance
