Variable frequency speed governing and dispersing machine is applied to the chemical industry and paper industry of paint, ink, paint and so on:           1, to grasp the nature of the material in detail.           2, according to the material and then for the high-frequency dispersion mixer selection.           3, again to determine the operating parameters of the frequency conversion and the structure of the design.           4, and then consider the cost of the inverter to consider the cost of installation into.           Frequency control and speed control of the conventional maintenance:           1, variable frequency speed control dispersion of the triangle belt should be equal to the length of the transmission box, elastic appropriate, tighten the sliding plate bolt, cover the top cover.           2, frequency control of motor speed dispersion machine if long-term do not have parking, must cut off the power supply, all clean, parts of the lubrication oil, main shaft and the cylinder oiled to prevent rust.           3, frequency control of motor speed dispersion machine rotating parts, gears, bearings, ball bearing, a shaft and a shaft sleeve and cylinder, a weekly oiling, in the use of the process found in overheating or abnormal noise should be timely inspection.           4, variable frequency speed control of the dispersion of the periodic inspection of the wearing parts, such as bearings, oil seals, etc., found that there is wear and tear replacement.
