AI Technical Summary

Technical Problem

The existing high and low pressure lubrication system pipeline flushing process requires disassembling and welding pipelines, which consumes a lot of manpower and materials, and poses a risk of pollution, affecting the construction period and cost.

Method used

In the design of the high and low pressure lubrication station, a fourth pipeline is added to connect the outlet of the low pressure oil supply pipeline and the outlet of the high pressure oil supply pipeline. A valve is installed on this pipeline to control the opening and closing of the high and low pressure oil supply pipelines, thereby achieving efficient pipeline flushing.

Benefits of technology

Rapid flushing of high and low pressure lubrication systems can be achieved through simple valve operation, reducing labor and material consumption, avoiding the risk of contamination, and improving work efficiency.
