This article addresses the issue of uneven lubricant flow among the five crossheads of a five-plunger mining pump under forced lubrication conditions. Utilizing ANSYS Fluent, we performed a fluid flow simulation of the forced lubrication oil path for the crossheads. The research primarily investigates the effects of throttle valve orifice diameter, main oil passage pipe diameter, and the design position of pipe expansions on the flow distribution within the lubrication channels for each crosshead.
