O Ring
Original Creation : 08-2014 O Ring O Rings are SEALING Devices made from Rubber Material. They have a ROUND Cross- Section. O rings are generally used to provide sealing of Fluid between two :- Static Components – i)Like between Filter casing and Filter Cover ii)Crankcase Door and Crankcase etc OR Between one STATIC and another Slow Moving RECIPROCATING DYNAMIC Component — i)Like a slow moving Piston inside a static Hydraulic Jack cylinder ii) Dynamic Spool and in a Static Direction Control valve Block. Etc. If you observe machineries carefully , you will realize the following types of NON O Ring sealing are used: Between – Static and Rotary components – LIP SEAL— i) Rotating shaft and Static Pump Body — ii)Rotating Shaft and Static Stern Tube -- etc For sealing between Static and Fast moving Reciprocating Component — we use PISTO...
Boiler blowdown
Original creation :25/8/2011 Boiler Safety There are three things which are required for successful firing of Boiler. Admission of fuel –Atomized or as per design (including correct viscosity/temperature etc) Sufficient Air to ensure Combustion— Both above are in a proper Ratio (stoichiometric Ratio) and designed to mix as per design. Ignition to kick start the Firing. The above happen at a particular sequence with meticulously calculated time intervals The entire process is Automated by Boiler Misfiring of a Boiler –results when one of the above gets disturbed. When there is a failure of complete of Fuel admission – Not much Harm might occur –except for the Boiler Not Firing. However if there is a Failure of admission of AIR or IGNITION , fuel would be inserted into the boiler furnace which eventually never could be ignited .So Accumulation of Fuel Takes place which may leads to Furnace explosion when an attempt is made to...
