AI Technical Summary
Existing lubrication systems require regular and tedious cleaning of the oil lines, which is inconvenient to use.
A fault-predictive lubrication device for sluice gate hoists was designed. Through the combination of a gear pump and an electric three-way ball valve, the automatic cleaning and delivery of lubricating oil is realized, avoiding the need for periodic cleaning of the main delivery pipe.
It enables automatic cleaning and delivery of lubricating oil, reducing the need for cleaning the main delivery pipe and ensuring stable operation of the equipment.
