Adding lubricating oil is the basic requirement to ensure the normal use of the oil-sweeping lobe pump

Sweeping oil lobe pump is suitable for conveying liquids with high viscosity and lubricity, but without solid particles. It is because of the simple structure, consisting of a stationary pump casing and a rotating rotor, which has no suction and discharge valves, relying on the rotor in the pump body to act directly on the liquid in the form of static pressure on the side in contact with the liquid, and discharging the liquid through the squeezing action of the rotating rotor, while leaving space on the other side to form a low pressure, so that the liquid is continuously drawn in. To sweep the oil lobe pump to add lubricating oil is to ensure its normal use requirements, so how to pump for the correct refueling?1, regularly check the oil level and oil quality of lubricating oil, in general, the normal oil level should be within 1/3-2/3 of the equipment oil level window or label. Oil replenishment method for the oil cup, its display oil level only represents the replenishment capacity, and the pump's bearing box oil level is to meet the operating requirements, the oil level in the oil cup is lower than 1/4 of its total volume can be considered for replenishment. 2, check and replenishment method, take out a small amount of lubricating oil as a sample and fresh lubricating oil for comparison, capable units can consider oil quality testing to ensure that the oil quality is qualified. If the sample looks cloudy, then it may be the result of mixing with water, which is often referred to as oil emulsification, and the lubricant should be replaced at this time. If the sample course darkens in color or thickens, then it may indicate that the oil has begun to carbonize and the old oil should be completely replaced. If possible, flush the oil circuit with fresh lubricant. When replacing the lubricant, make sure the new and old type of lubricant being replaced is the same and replenished to meet the required oil level.3. Using an oil bath type lubrication system, if the oil temperature is below 60℃(140F) and the lubricant is not contaminated, it is sufficient to replace the lubricant once a year. If the oil temperature is 60-100℃(140-210F), the lubricant needs to be replaced four times a year. If the oil temperature is 100-120℃(210-250F), the lubricant needs to be changed once a month. If the oil temperature is above 120℃(250F), the lubricant needs to be replaced once a week. 4. Correct installation and maintenance are important factors for the normal operation of the bearings, meanwhile, attention must be paid to keep the cleanliness of the pump bearings. Bearings must be protected from contaminants and moisture, and must have proper installation and lubrication. In addition, the design of the bearing mating, the condition of the oil seal, the form of lubricant and the replacement cycle and specialized maintenance also play an important role and must be paid attention to.
