The pump needs regular inspection, maintenance, and maintenance, in which the pump refueling, is one of the items to be maintained. How to give the pump the correct refueling?
1, regularly check the oil level and oily oils, in general, the normal oil level should be the equipment oil level window or labeled 1/3-2/3 range. The oil filling way for the oil Cup, its display oil level only represents the oil filling ability, and the pump's bearing box oil level is satisfies the operation request, the oil level below its total volume 1/4 may consider supplements the oil.
2, inspection and replenishment methods, the removal of a small amount of lubricating oil as a sample and fresh lubricating oil for comparison, the ability to consider the unit can be oily testing to ensure that oil qualified. If the sample appears to be cloudy, then it may be the result of mixing with water, which is often said to be emulsified oil, at this time should replace lubricating oil. If the sample path darkens or thickens, it may indicate that the lubricant has already begun to carbonation and that the old lubricating oil should be thoroughly replaced. If possible, use fresh lubricant to rinse the oil circuit. Replace the lubricating oil, should ensure that the replacement of the new lubricating oil, the old model is the same, and add to meet the required oil level.
3, the use of oil-bath lubrication system, if the oil temperature in 60 ℃ (140°f) below, and the lubricant is not contaminated, then one years to replace the lubricating oil can be. If the oil temperature in 60-100 ℃ (140-210°f), then one years need to replace four lubricants. If the oil temperature is 100-120 ℃ (210-250°f), the lubricant will need to be replaced once a month. If the oil temperature is above 120 ℃ (250°f), the lubricant will need to be replaced once a week.
4, the correct installation and maintenance is the important factor of the normal operation of the bearing, at the same time, must pay attention to maintain the cleanliness of pump bearings. Bearings must be protected against contamination and moisture by 4 and must be properly installed and lubricated. In addition, the design of bearing column, the status of oil seals, the form of lubricant and the replacement cycle and special maintenance also play an important role, all must be paid attention to.
