Regarding the lubrication of pump equipment
Thread Content
Do ordinary magnetic pump require lubrication? If necessary, where on the pump should lubrication be applied? What lubricants are commonly used? Seeking help from experts! ! !
Of course, lubrication is needed. The bearing with external magnetic steel driven by the motor requires regular greasing for lubrication, and the motor bearings also need to be lubricated.
External magnet bearings require regular greasing for lubrication, while motor bearings also need to be lubricated
It depends on the type of magnetic pump; those without a bearing housing do not require lubrication. For those with bearing housings, check what type of bearings are used. If bearings with covers at both ends are used, no lubricant is needed; simply replace them regularly. If there is a grease fitting on the bearing housing, it is necessary to apply grease regularly. If thin oil lubrication is used, lubricants of different grades must be applied according to the temperature, and they need to be replaced regularly.
Lubricant should be added regularly – how often is that? The usage time of different pumps also varies, right?
Yes, the replacement cycles for different pumps vary as well; this is related to speed and temperature. For pumps, regardless of the interval between reapplication of lubricant, the bearing’s lubricant should be replaced at least once every six months. Assuming a pump with a rotation speed of 2950 rpm, the normal lubrication replacement cycle is 3000 hours. The interval for refilling lubricant is calculated based on a working temperature of 70°C; for every 15°C increase in bearing temperature, the interval for refilling lubricant should be reduced by half ； For every 15°C decrease, the interval between refilling the lubricant should be doubled. Different types of bearings have varying requirements from different manufacturers; it is still necessary to refer to the manufacturer’s Installation, Operation, and Maintenance Manual IOM
