Four-ball Machine For Hydraulic Support Oil Fully Automatic Four-ball Equipment
Product Introduction
The hydraulic support oil four-ball tester is a newly launched four-ball friction testing machine of Hengxu brand, which adopts the latest guidance and control technology. It mainly conducts tests on the anti-wear performance of hydraulic support oil and the anti-wear performance of hydraulic support oil additives under extremely high point contact pressure conditions. It evaluates the carrying capacity of the lubricant. It includes three indicators: maximum no-stall load Pb, sintering load Pd, and comprehensive wear value ZMZ. This four-ball friction testing machine can also perform long-term anti-wear tests of lubricants, measure the friction coefficient, and record the friction force and temperature curves. The electro-hydraulic servo type four-ball friction testing machine can be equipped with a high-precision measuring device to realize the calculation and display of the wear spots of the friction pair on the screen, as well as measurement and recording. With special accessories, it can also conduct end face wear and material simulation tests. The appearance reference picture is shown in the above figure.
