It is feasible to add grease to the pump during operation, but certain operating specifications and precautions need to be followed. According to multiple evidence, the addition of grease to the pump is usually carried out during operation, but it is necessary to ensure that the amount of grease added is appropriate to avoid excessive heat and damage to the bearing.
The specific steps are as follows:
1、 choose the right grease: choose the right grease according to the type of pump and working environment. At present, the commonly used lubrication of the pump is butter and thin oil, and ensure the purity of the grease to avoid dust, sand and other impurities.
2、 regular check and add grease: the pump needs to check and add grease regularly to ensure its normal operation. For example, check once a month and inject about 0.1 ounces (2.8 grams) of grease at a time. For some types of pumps, such as PACO single-stage end-suction centrifugal pumps, the initial injection of grease remains in good condition for one year or up to 2000 hours under operating conditions, after which regular lubrication maintenance must be performed.
3、 avoid excessive addition: when refueling on the bearing, just add grease until the steel ball can be sealed flat. Too much grease will cause the bearing to overheat and accelerate the bearing failure.
4、 monitoring temperature and vibration: After adding grease, the temperature and vibration of the pump should be monitored to ensure that the oil quality of the grease is good, no change, and the pump is operating normally.
5、 keep the environment clean: when adding grease, should keep the surrounding environment clean, to avoid dust, sand and other impurities mixed.
In short, it is feasible to add grease to the pump during operation, but the correct operating steps and precautions must be followed to ensure the normal operation of the pump and extend its service life.
