1. What Is A Stage In A Steam Turbine?
In an impulse turbine, the stage is a set of moving blades behind the nozzle. In a reaction turbine, each row of blades is called a “stage.” A single Curtis stage may consist of two or more rows of moving blade.
2. What Is A Diaphragm?
Partitions between pressure stages in a turbine’s casing are called diaphragms. They hold the vane-shaped nozzles and seals between the stages. Usually labyrinth-type seals are used. One-half of the diaphragm is fitted into the top of the casing, the other half into the bottom
3. What Is A Balance Piston?
Reaction turbines have axial thrust because pressure on the entering side is greater than pressure on the leaving side of each stage. To counteract this force, steam is admitted to a dummy (balance) piston chamber at the low-pressure end of the rotor. Some designers also use a balance piston on impulse turbines that have a high thrust. Instead of piston, seal strips are also used to duplicate a piston’s counter force.
4. What Is The Operating Principle Of A Reaction Turbine?
A reaction turbine utilizes a jet of steam that flows from a nozzle on the rotor. Actually, the steam is directed into the moving blades by fixed blades designed to expand the steam. The result is a small increase in velocity over that of the moving blades. These blades form a wall of moving nozzles that further expand the steam. The steam flow is partially reversed by the moving blades, producing a reaction on the blades. Since the pressure drop is small across each row of nozzles (blades), the speed is comparatively low. Therefore, more rows of moving blades are needed than in an impulse turbine.
5. What Is A Combination Thrust And Radial Bearing?
This unit has the ends of the Babbitt bearing extended radially over the end of the shell. Collars on the rotor face these thrust pads, and the journal is supported in the bearing between the thrust collars.
6. What Is A Tapered-land Thrust Bearing?
The babbitt face of a tapered-land thrust bearing has a series of fixed pads divided by radial slots. The leading edge of each sector is tapered, allowing an oil wedge to build up and carry the thrust between the collar and pad.
Tell Me About Yourself: Top 6 Example Answers for a Job Interview
This video showcases six examples of how to respond when someone says,
7. Tell me about yourself,” during an interview?
At the beginning of the conversation, your interviewer will likely start out by asking you about yourself. They are seeking to understand your qualifications, what led you to the job and generally why you think you’d be a good fit. The key here is making your answer concise and direct, including only professional information relevant to the job. Your answer should be structured as follows:
1. Start by describing your background with a summary of your most impressive responsibilities: “I’ve been a hostess at XYZ Restaurant for just over two years where I greet and seat customers, assess wait times, fulfill to-go orders and answer the phones. I love the lively and busy environment—we often have Friday and Saturday wait times of one hour or more…”
2. Next, briefly summarize your previous experience with key achievements: “…Before working at XYZ Restaurant, I worked in retail as a floor associate for five years. Working in retail developed the customer service skills that make me a great hostess, offering a top-tier dining experience from the moment customers walk in the door. It also equipped me with the ability to work quickly under pressure
8. Why do you want to work here?
Interviewers often ask this question to determine whether or not you took the time to research the company and think critically about whether you’re a good fit. The best way to prepare for this question is to do your homework and learn about the products, services, mission, history and culture of this workplace. In your answer, mention the aspects of the company that appeals to you and aligns with your values and career goals.
Example answer: “The company’s mission to help college grads pay off their student loan debt resonates with me. I’ve been in student loan debt myself and would love the opportunity to work with a company that’s making a difference. Finding a company with a positive work environment and values that align with my own has remained a priority throughout my job search and this company ranks at the top of the list.
9. What Is Important To Remember About Radial Bearings?
A turbine rotor is supported by two radial bearings, one on each end of the steam cylinder. These bearings must be accurately aligned to maintain the close clearance between the shaft and the shaft seals, and between the rotor and the casing. If excessive bearing wear lowers the he rotor, great harm can be done to the turbine.
10. How Many Governors Are Needed For Safe Turbine Operation? Why?
Two independent governors are needed for safe turbine operation. One is an over speed or emergency trip that shuts off the steam at 10 percent above running speed (maximum speed). The second, or main governor, usually controls speed at a constant rate; however, many applications have variable speed control.
