How to maintain the water pump bearing?

Water pump bearing maintenance methods:

1, the new pumps in use, generally after 100 hours of operation shall replace bearing grease (oil), after every 500 hours of operation to replace a time.

2, the use of grease lubricated bearings flow, after running 1500 hours, replace the grease, filling the oil is not too much or too little, because the grease too much or too little will cause bearing heating, refueling general grasp in bearing chamber volume of 1/2 to 2/3 is appropriate.

3, for the use of lubricating bearings, bearing oil should be added to the composite to a predetermined position.

4, containing oil or grease containers should be clean, usually should be sealed, there should be no dust, iron filings and other debris, to avoid damage to the bearings

5, the motor bearings generally use sodium based grease, this grease is characterized by high temperature (125 ℃), but easily dissolved in water, so you can not use it for water pump bearing lubrication.
