Diesel Generators classification

Thermal power generators is usually separated into two major categories of unit and hydro units in thermal power generating units, he also includes a steam turbine, gas turbine and diesel generator sets and so on. Have dissimilar lubrication necessities. And although many types of motors, which are considerably the same lubrication necessities.

First, the turbine generator set lubrication

    There Pelton turbine, counter-style (can be separated into Axial, Tubular, Francis, oblique flow, etc.). In general are low, at room temperature, under invariable load exercise, but the work environment is more humid. Requires the use of anti-rust, anti-emulsification and good water reparability lubricants. Most small hydro behavior lubrication and governor institutions in commission systems use the same lubrication system, while large hydro-oriented working system bearings and adjusting instrument separate lubrication system, Francis and Kaplan turbine guide vanes, water Bucket needle turbine working mechanism all use a good anti-trust or No. 0 on the 1st calcium or lithium grease lubrication.

Second, the thermal power generating units’ lubrication

    1 gas turbine and steam turbine generator lubricating characteristics: turbine spindle bearings, lubrication necessities are more characterized by a number of large engines, the journal up Φ600mm above boundary of the shaft speed can sometimes be more than 100m / s, usually dynamic pressure or hydrostatic bearings, with a enthusiastic fuel organization loop supply lubricating oil, and its gear box, speed machine (device) exciter and other free cycle oil or oil bath lubrication oil.

    2 turbine steam turbine lubrication than normal to much more challenging, is characterized by small gas generator oil hotness is higher, often need to use imitation oil or phosphate-based aviation gas turbine oil lubrication flammability.

    3 Diesel generators lubrication: diesel generator set diesel pump inspiration is its lubrication coordination and the engine lubrication system and are normally medium-speed diesel engine using high-power heaviness movement lubrication is separated into wet and dry sump lubrication system, large Some models of the cylinder liner using grease lubrication. Engine oil is normally used on the 30th or 40 diesel engine oil, also used on the 30th or 40 medium-speed cylinder diesel engines or large marine diesel oil lubrication. Exhaust gas turbocharger in general not compulsory TSA46 or 68 turbine oil lubrication. Hydraulic governor not compulsory TSA32-68 turbine oil lubrication. Barring mechanism using L-CKC or L-CKB100-150, Industrial gear oil lubrication
