After a period of use, the grease of screw blower will have performance aging and leakage consumption, so it needs to be supplemented or replaced in time. Roots blower uses grease, which is usually replenished every three months. Whether it needs to be replaced depends on the quality of grease. Main judgment basis:
(1) Check the screw blower for mixing too many hard particles. During inspection, take a small amount of grease with your fingers for twisting and pressing, which can be judged by feeling;
(2) Inspect the screw blower for oxidation and deterioration. If it has been oxidized, it can be distinguished from the appearance. At this time, the color of the grease becomes black or deepened, and a hard film will form on the surface.
(3) Different kinds of grease can't be mixed, new grease and old grease can't be mixed, so when changing grease, the waste grease should be completely removed, and then filled with new grease.
(4) The filling of lubricating grease should be appropriate. Too little filling will result in insufficient lubrication. Overfilling, excessive stirring and sharp temperature rise of grease cause oil separation, decomposition and leakage.
