Valve Lapping



     Gate Valve And Ball Valve Lapping Works

               Valve Maintenance works


Lapping is the process of cleaning the control valve for maintenance purposes. The lapping is done with compounds that has roughness, and used to clean valve disc and nozzle seats etc., Every seat and disc from a relief valve or block valve, in general, must be subjected to lapping.


Gate Valve Service-----


Valve Lapping is basically sanding down the surface of the Valves (which allow fuel and air to flow in, and exhaust to flow out) and the Head (Holds the Camshafts and valves) where they make contact with each other.








Lapping is process in GATE VALVE where Two mainly parts That is 

1. Gate DISC

2. Gate SEAT

On both face we making proper contact face by help rubbing process.

if any one parts more cuts face in running time than leakage will start.


Lapping (Facing) on GATE DISC----





Lapping (Facing) on DISC SEAT----





Ball Valve Servicing----



      

 




Current buffing processes used to polish spherical balls and cups can detrimentally effect the roundness. Current machines used to polish spherical balls and cups have between 10-20% failure rate. The machine and process developed at Kemet International produces a mirror polish, holds geometry and can correct these failures while maintaining roundness down to 2 microns. The whole process takes less than 9 minutes. The system can be used on most materials including ceramic, natural metals and alloyed metals.

Condensate extraction pump in thermal power plant

WHAT IS CEP (CONDENSATE EXTRACTION PUMP) -  This pump is in actual efficiency booster in a thermal power plant. As we all know that very high temperature and pressure steam expands in a steam turbine and this expanded(low pressure and low temp) steam can go waste if CEP doesn't perform it's function. CEP pump circulate the -Condensate(conversion of steam into water in condenser) again into deaerator tank which prevent plant from a huge loss of water. This water can be used for making deaerator level. Condensate Extraction Pump, as the name suggests the CEP is required to extract the condensate from the Condenser. Condenser is the equipment where all the steam gets condensed and the condensate is extracted out of the same by CEPs. so where the Condensate goes after coming out of the condenser, so it goes to the DEAERATOR by moving through a series of LP heaters, where the temperature of the extracted condensate is increased to a certain degree. In deaerator the soluble gases are...

Boiler tube

                         THERMAL POWER PLANT BOILER TUBES A  water tube boiler  can be defined as a Steam  boiler  in which the flow of  water  in the  tubes , as well as hot gases, enclose the  tubes . Not like fire  tube boilers , this  boiler  attains high-pressures, as well as high-steam capabilities, can be achieved. The  steam  generators of the  660 MW  units would be 100%  coal  fired and would be rated to generate about 2170 t/hr each, of superheated  steam  at about 250 kg/ cm2 pressure and 568°C temperature. Reheat  steam  temperature would also be 568°C. Boiler Erection of Water Tubes...... How do I find a leak in my boiler tube? For detecting  boiler tube  leaks, plant operating engineers constantly monitor  boiler  furnace vacuum, which is maintained between a -10 to -20 mm water column...
