Multi-chapter guide to Vacuum Pumps describing: what a vacuum pump is, how a vacuum pump works, types of vacuum pumps, wet vs. dry lubrication, vacuum ranges.
This chapter presents an overview of lubrication system and its types. A discussion of system operations of the more common types of systems used for critical equipment is pursued. The classical lube system arrangement consists of a steam turbine driven main pump and motor drive auxiliary pump. A...
Pelton Impulse Water Turbine Design Formulas This is a water turbine in which the pressure energy of the water is converted wholly to kinetic energy in one or more jets which impinge on buckets disposed around the periphery of a wheel. Progressive Cavity Pumps Review Progressing cavity pump" is...
Lubrication systems control the volume and pressure of the lubricant to be applied to the surfaces of the moving machine parts in contact. They promote the smooth and healthy operation of the machinery. Through lubrication systems, the lubricant is applied and distributed efficiently and regularly. T...

, such bearing uses magnetic levitation to support a load or function. They basically work on the principle of electromagnetic suspension. Since magnetic bearings operate without physical exposure, they have extremely low friction and vibration. They can also work in a vacuum and without lubrication....
Do mechanical seals need lubrication? When the seal faces rotate against each other, it would generate face friction and heat. So it would wear and quickly fail without any form of lubrication. Thus, lubrication is required during the use of mechanical seals. ...
They are sometimes called aspirators, Venturi pumps, or jet pump ejectors. Because eductors are non-mechanical, they do not include moving parts or require lubrication. Because they do not require electricity, eductors can be used in hazardous environments. Features Eductors use the kinetic ...
