1) Newly used water pump; usually replace the smooth grease (oil) after 100 hours of operation; replace it once every 500 hours in the future. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2) Select smooth bearing with smooth grease; after running for 1500 hours; replace the smooth grease; the amount of oil added may not be too much or too little; too much or too little smooth grease will cause the bearing to heat up; The volume of the bearing chamber is 1/2~2/3.
3) Regarding the selection of smooth oil smooth bearings; the amount of oil should be added to the regular orientation.
4) The container with smooth oil or smooth grease should be clean; it should be sealed normally; there should be no dust, iron filings, etc.; avoid damage to the bearing.
5) Motor bearings usually use sodium-based smooth grease; this smooth grease is characterized by high temperature (125 ° C); but it is easy to dissolve in water; so it can not be used for the smoothness of water pump bearings.
