Issue of changing oil lubrication to grease lubrication for water pumps
Thread Content
The speed of this water pump is 970 r/MIN; it has two 6330 bearings at each of the inner and outer ends. It is currently lubricated with oil, but there is oil leakage. Is it possible to switch to grease for lubrication? What kind of grease should be used if possible?
The rotation speed is indeed not very high; it might be worth considering making a change. Replace it with an automatic fat injector. Adjust the fat addition frequency properly.
The low speed can certainly be adjusted. The type of grease to use depends on the temperature; it’s advisable to design a filling hole and an oil drainage hole. As some moderators have mentioned, an automatic grease feeder can further reduce maintenance costs and minimize the risks associated with maintenance
Switching to lipid lubrication is no problem; the bearings of our company’s 4,000-cubic-foot circulation pumps were changed 6 years ago, and the results have been excellent. However, it is essential to ensure regular replenishment and replacement of the lubricant
How long is the cycle approximately? For grease lubrication, just add grease directly, right? No need to make changes on the device, right?
The lubricating oil chamber is generally larger, while the grease chamber is usually smaller. However, there must be clear routes for adding and removing oil; the oil level should neither be too low nor too high. If the oil level is too low, the bearings can burn out, and if it’s too high, the bearings will overheat. The oil change interval should follow that of other equipment, typically ranging from 1 to 6 months, depending on the conditions of the equipment and its operating status – there is no fixed standard. It is important to monitor the operating temperature regularly.
It can be modified, but it’s necessary to ensure that fat is added; after the modification, the bearings will wear out more easily, and it will also be necessary to make adjustments to the water seal
It’s best not to make any changes, as lubricants have three main characteristics: one is lubrication； The second is to carry away heat ； Third is to remove mechanical impurities. Grease has only one function. If changes are needed, it’s best to submit a report so that the relevant professional departments can make the final decision. For reference. The same approach applies to dealing with oil leaks: it is necessary to contact the relevant authorities, who will then take charge of coordinating with the manufacturers to resolve the issue – this is the correct way to do it. Even if you are confident that you can complete it and that it will indeed work, you still need to obtain approval from the relevant authorities before proceeding. Unless the device is yours, you can do whatever you want:lol
Agreed, it makes sense. If the operating conditions are stable and there is sufficient bearing load capacity, it can be modified； However, due to either extreme operating conditions or improper operation and maintenance, there are still certain risks associated with making changes. It is advisable to develop a plan, submit it for review, and follow the proper procedures. After all, making improvements doesn’t necessarily yield any results; there are many problems if the improvements aren’t done well
