At the same time, the contact area between the ball and the raceway of the deep groove ball bearing is small, so the friction coefficient is small, which can reduce energy loss and improve mechanical efficiency.In short, deep groove ball bearings are a com...
trunnion ball valve; double-piston effect; valve seat; SolidWorks fluid flow simulation; natural gas pipelines; Repower EU Plan1. Introduction The natural gas demand in the EU reached 15,834,900 terajoules in 2021 [1]. Gas represents 21.5% of the EU’s primary energy consumption and covers ...
Two different positioning distances were examined using the step input test, namely mid-stroke (100 mm) and near fully extended (150 mm), where only one valve (Valve 1) of the IPA system was utilized to extend the cylinder stroke. In contrast to the step input test, the multistep input...
