However, because the requirements of each part on the grease filling amount are different, the output proportion of each filling port of the distributor is usually determined in advance according to the maximum working condition requirement, and the model selection of the grease pump is carried out, so that the output flow of the grease pump is ensured to be constantly larger than the required maximum flow. When a part meets the flow filling requirement, the grease filling quantity of a grease filling position with relatively large demand is insufficient and the grease of the grease filling position with relatively small demand overflows excessively due to the fact that the output proportion of the distributor cannot be adjusted. Only when the grease filling amount of all the component filling positions meets the requirement, the filling amount can be controlled by stopping the grease pump, and the grease filling is resumed by restarting the pump, so that the grease pump cannot exert the maximum efficiency, the grease consumption is larger than the actually required flow, and the cost is increased.
