||CENTRIFUGAL COMPRESSORS SURGE CONTROL SYSTEM ||
n the oil & gas industry, Engineers often spend hours performing calculations to design a gas compressor system. In the case of Gas transmission through pipelines, the performance of a gas compressor becomes critical and can decide whether you are going to see gas production coming to a halt or it's just 'Another Day, Another Dollar'. Design methods are initiated by doing 'steady state' calculations, However nothing can be more frustrating for the engineer to watch his/her 'steady state design' ending up conking out the gas compressor once its built, because he/she failed to judge whether the system was under-designed or over-designed.

|| FLUID HEAD IN CENTRIFUGAL COMPRESSOR ||
Переглядів 5006 місяців тому
centrifugal compressors the head is determined by the volume flow through the unit. In the case of an axial-inlet centrifugal compressor (typical of integrally geared units), an appropriate length of pipe serves to smooth the flow of gas into the eye of the first impeller.
|| DYNAMIC COMPRESSOR ||
Переглядів 5596 місяців тому
Dynamic compressors are rotary continuous-flow machines in which the rapidly rotating element accelerates the air as it passes through the element, converting the velocity head into pressure, partially in the rotating element and partially in stationary diffusers or blades.
|| INDIVIDUAL STAGE AND OVERALL PERFORMANCE OF COMPRESSOR ||
Переглядів 1696 місяців тому
The main difference between single- and two-stage compressors is the number of times that air gets compressed between the inlet valve and the tool nozzle. In a single-stage compressor, the air is compressed one time; in a two-stage compressor, the air is compressed twice for double the pressure
|| POSITIVE DISPLACEMENT COMPRESSOR ROTARY LOBE ||
Переглядів 1786 місяців тому
A rotary lobe vacuum pump is a positive displacement pump that uses rotating lobes to generate vacuum. Two three-bladed rotary lobes are mounted in parallel within the housing. They operate in opposite directions. The pumped medium is trapped through the rotation of the lobes, compressed, and transported to the outlet.
MECHANISM OF FOULING & ITS EFFECT ON THE OPERATING POINT IN COMPRESSOR
Переглядів 3366 місяців тому
Compressor fouling reduces the compressor mass flow rate, pressure ratio and the cycle efficiency which subsequently leads to a reduction in power and increase heat rate [11; 12]. In a bid to recover lost power, firing temperatures are raised which has a detrimental effect on the blade creep life.

||Rotating Equipment and its classification||
Переглядів 4448 місяців тому
Rotating Equipment is a term generally used in the oil and gas and process industries to describe mechanical components that use kinetic energy to move fluids, gases, and other process materials. These include, but are not limited to, engines, compressors, turbines, pumps, generators, blowers, and gearboxes.

Single-stage and multistage centrifugal Compressor
Переглядів 8179 місяців тому
A centrifugal compressor is an operating turbomachinery in which one or more rotating impellers supply dynamic energy to a compressible fluid with the aim to increase its pressure. When the inlet nozzle is not axial, an inlet volute is necessary to convey the gas into an annular stream to feed the (first) impeller.
what are causes of surge
Переглядів 3,9 тис.11 місяців тому
Compressor surge is a form of aerodynamic instability that occurs when the amount of gas the compressor is trying to compress is insufficient for the size of the compressor and the blades lose their ability to transfer energy to the fluid, causing a reverse flow of the gas1234. It causes strong oscillations of pressure and flows in the compression system, which can lead to vibration and damage ...
What determines the compressor curve shape
Переглядів 59111 місяців тому
The compressor curve shape shows the behavior of a fluid going through a compressor. It depends on the compressor speed, the number of stages, and the geometry of the components such as the impeller, diffuser, and collector123. What kind of compressor are you interested in?
Thank you very much mr engineer❤
THANK YOU THANK YOU THANK YOU
You have a familiar voice, did you teach courses on the online ibew iPrep videos?
Peace for you. Mr. Eng I asking for infrared thermetre how i calculate the enthlpy defferenance by using temperature in and out frist stage of 3 stage centrifugal compressor i get those measurements using infrared thermetre.. Thank you
Thank you for information and the class. It is quite educating .👏
This video has a problem and doesn't show anything after 10 minutes .
Okay I will check it
"In dirty condition pressure ratio is constant so new p2 is obtained". But we know p2 is function of downstream condition, what is your response?
Can I get your WhatsApp number.i need some clarification sir
Good video, you should have included the bibliography from where you got de the information.
What means head in the video
height of the pumping
@@karoly365 thank you but here he is speaking about compressor not pumps
plz clarify >0.002inches or >0.02 inches after which piping correction is required
Would be interested to see a similar video but with mass/standard flow instead and how that changes during this process change
Good day Mr Engineer. Thanks a lot for the explanation. Kind regards
You are welcome
❤
Please upload video on loading part
what are the factors that affect the numbers of condensates draining in a reciprocating compressors?
Many thanks Mr Engineer for a great explanation! 🙂
You are welcome!
you have a really nice voice. It's so calming
Thanks
So, that's how they are going solve thermal expansion in hyperloop🤔
Do you have an idea about ''Hot Gas By-pass valve"??
Thank you so much for these informations
Please check the answers are not matching, Ev = 0.882948 Evd = 0.606648 However final volume is correct. Thank You!
Thanks
yes blowers does have surge protection, but instead of recirculation lines the usually have Blow-off valves
Nice Explination
Very Very Nice Explination.
1 mistake is visible towards the end, it shows the pressure breaker ring next to the big flange, when it should be next to the smaller 1. ie inner most ring, towards pressure of the cylinder.
. DJ Sahab Jo booster pump hota hai usmein bearing change karne ke liye bad Mein Pani Aata Hai usmein Pahle Is Tarah chalta hai bad Mein Pani Chhod deta hai aise kyon hota hai mere ko bol dijiye
Great video. Thank you so much.
Great, very useful...thx
Video title is multistage pump and the actual content is a centrifugal compressor.
Thanks
Crap, Blablablabla
what is reason water moisture mix in oil
I also want you to make such videos on gas driven engine.
I love to watch ur video they're very informative. Thanks for sharing n keep going.
Glad you like them!
Very Informative 😊
how about centrifugal vs screw compressor sir
screw is a type of PD compressor if i am not mistaken.
Hi friend in this software raft foundation There is ?
Hello, your videos are very informative. Great initiative
Glad you like them!
Yes very much. I am a Rotating equipment engineer with EPC firm and roght now executing a project with DR's two sets of compressors
It is a nice presentation I have got a lot of additional knowledge , please continue your lecture especially on valve maintenance Regards
Ok. Thanks
Hello. How are you? Does surging occur in blower systems?? Can u help me solve the problem in my process? Thanks..
Very simplified this hard topic
Knowledge gain
Thanks sir
This video is awsome!
Great videos
Thanks!
Sir, Why flow transmitter placed in suction and PT in discharge..why not Vice versa?
Good explanation..
Keep watching
Nice
