The ways lubrication pump is coupled to the hub of the main pump sheave. But both pumps are driven by the same motor. This pump has a strainer.
1.What is the function of the ways?
2.Which is this pump? I don't think the description is clear.It will give me much pleasure to hear you!
"Ways" (plural) is a shorthand for "guideways." A piece of machinery that moves back and forth (as opposed to rotating machinery) will move along "ways."
The pump circulates oil for lubricating the ways. It's a ways lubrication pump.
There is also apparently a "main pump." Both pumps are on the same shaft, being driven by the same motor.
