How to start a Pump

-
This is observed that in power plant or any industry people are not aware of the basic safe operation norms of the equipment . As a result there is frequent failure  of the equipment. So if we follow the proper procedure and maintain it as standard operating procedure for operation of the equipment it can be  avoided.

How to start a Pump 

 There are different methods for different types of pump .
 1. Centrifugal Pump 
2. Positive displacement Pump- Reciprocating, Gear, lobe , piston, diaphragm, screw, hydraulic pump etc 


Start up check list for pump

1.         1.       Suction valve is in open condition

2.       Discharge valve is in closed condition

3.       Recirculation valve is in open condition

4.       Lubrication – Oil or grease

5.        Sealing system if applicable

6.       Suction level of the fluid should be normal

7.       Priming system readiness

8.       Freeness of the shaft

9.       Motor IR and connections with protection system

10.   Suction foot valve or  strainer condition

11.   Direction of rotation of the pump

12.   Alignment with motor

13.   Check proper fixing of the foundation bolts

14.   Piping supports

15.  Protection and Interlock system is in line

16. Flushing- Connected pipe line and storage tank are to be thoroughly cleaned and flushed

17. Bearing  Cooling system is in line

1.    

Start Up Procedure

If above conditions are fulfilled do the following

1.       Priming- fill the pump with fluid and release air

2.       Start the pump

3.       Observe the shut off/discharge pressure, current , bearing   vibration, temperature and noise

4.       Open the discharge valve and close re-circulation valve gradually

5.        Observe the points no3

6.       If VFD is installed, increase the speed gradually, do not run pump in minimum speed for longer time.

7.       Observe the point no3

8.       For bigger pump observe axial  shift, balancing leak off pressure, delta- T across the pump

9.       If there is any abnormality stop immediately - rectify and restart it

What are the types of CFBC Boiler

 CFBC technology:   Coal was the main fuel in power plant and cost of coal was very cheap before 80s in India. I have seen the power plant used the coal of GCV 4000kcal/kg to 5000kcal/kg. But gradually as the industries grow up,   the demand for various grades of coal are increased and cost of generation is becoming the predominant factor. Secondly the supply of high grade coal also comes down due to depletion of coal in mines. So need of the usage of lower grade of coal arises, First AFBC technology and later on CFBC technology of Boiler are developed to use the lower grade of coal   from 2200Kcal//kg to 3000Kcal//Kg of GCV. What are the other benefits of CFBC technology? 1.        High combustion efficiency: as high as 98% 2.        Wide range of fuel can be used: lower grade of fuel i.e sponge iron kiln reject (dolochar )GCV as low as 1000 kcal/kg can be used with mixing with higher grade of coal , coal m...

Reason For Silica Deposition In Turbine

  Silica Deposition in Turbine How is silica coming to turbine? There are two types silica : 1. Colloidal Silica: SiO2-O-SiO2-  More prevalent in water from surface source pH>7,, this is insoluble and mainly removed by UF, Coagulation, Nano filtration. 2. Reactive Silica: (OH)3Si-O- This is soluble  and removed by EDI (Electro deionisation), RO. But  Silica is coming in turbine through steam from Boiler. Silica in steam should be less than 0.02ppm . It can be increased due to following reason: 1.        High silica level in steam drum: : Silica in drum should be less than 2ppm upto 100ata drum pr ref fig below (drum pr vs silica level and pH) .If it increases above this value, blow down (IBD and CBD ) should be operated to control the silica level.   Secondly it can be seen when boiler is not properly cleaned during commissioning time. It can also be seen due to lower steam separator efficiency in boiler drum. 2.   ...
