(1) the new pump used for use is usually replaced by grease (oil) after 100 hours of operation, and then changes 1 times per operation for 500 hours.
(2) when lubricated rolling bearings are lubricated, after running for 1500 hours, the grease should be replaced. The amount of oil can not be too much or too little. Because too much grease or too little grease will cause the bearing to generate heat. The volume of fuel is generally controlled by the volume of 1/2 to 2/3 in the bearing chamber.
(3) for bearings that are lubricated by lubricating oil, the amount of oil should be added to the specified position.
(4) the containers for lubricating oil or grease should be clean and should be sealed well at ordinary times, and there should be no dust, iron and other debris, so as to avoid the damage of the bearings.
(5)The bearing of agricultural machinery is usually made of sodium base grease. The characteristic of this grease is high temperature (125 degrees), but it is easy to dissolve in water, so it can not be used for lubrication of water pump bearings.
