When the ice-class propeller sails in an icy sea, it is affected by external factors such as water, ice, and cavitation, process of mutual interference extremely complicated. In order to study influence water cavitation on load during ice-propeller milling process, a test platform for ice–water action was constructed. The single blade were measured air (atmospheric pressure decompression condit...

In order to solve the problems of lack of heart donors for transplant, implantable ventricular assist systems (VAS) have been developed to assist the failing heart ventricle. One of the components of a VAS is a blood pump that connects the left ventricle to the aorta. Therefore, the pump flow rate is influenced by the cardio-vascular system. To control the flow rate through the blood pump, real...

Introduction: The progress of science has made it possible to create new quantum engines (QEs) powered by physical vacuum energy. A QE will generate a vector-based propulsive force, or thrust, applicable the vehicle body directly, with no transmission required. Traditional cars be upgraded QEs and thus converted into quantomobiles. thrust application at point body, hovering above bearing surfac...

Cooling Water Pump berfungsi sebagai penyuplai air untuk sistem pendinginan di PLTA Asahan 1 yang mendinginkan minyak dan udara. Sistem pendingin udara terdapat pada Generator Air Cooler, system Thrust Bearing Oil Turbine Guide Upper Lower Cooler. bersumber dari draft tube (pipa pembuangan) dipompakan oleh Pump. digunakan setelah akan disalurkan kembali melalui pemipaan menuju

Axial thermal deformation and axial stiffness are the leading technical indicators affecting face-grinding spindle manufacturing accuracy. However, supported by rolling bearings lubricated with grease has a disadvantage regarding temperature rise, stiffness, rotational To overcome this issue, study proposes novel combined bearings, which include water-lubricated hydrostatic thrust bearing two a...
