Study of Steam Turbine Back Pressure Type Mechanical Seminar Report

Introduction to Study of Steam Turbine Back Pressure Type Mechanical Seminar Topic:

In generation of power turbine has a very important role. In thermal power electricity is generated by producing steam on burning coal and to manage steam we use steam turbines in thermal plants. A steam turbine is nothing but a heat engine in which by expanding the steam through nozzle steam energy is converted to kinetic energy. By impinging resultant kinetic energy on rings of moving blades mounted on rotor which is a rotating element, KE is converted into force. Moving blades deflect the jets of steam.

 Steam turbines may use in power plant, in process industries and for transport. Steam turbine can be defined as a mechanical device which converts thermal energy of pressurized hot steam to useful mechanical work. During expansion of steam, steam undergoes multiple stages so the steam turbine takes much of its thermodynamic efficiency. Steam turbine contains fixed and moving blades which substantially designed so that they can withstand the applied steam pressure.Steam turbines found wide use in marine applications like for vessel propulsion systems. For aerospace applications in the field of power generation gas turbines are using instead of steam turbines.

     In this paper we are going to describe the types of turbines are high-pressure (HP), low-pressure (LP) and astern turbines and their uses, advantages.The configuration of these different steam turbines is different even though several components in these turbines are common.

Heat from the steam is extracted by the steam turbines and by expanding it from high to low pressure, steam turbine transform it into rotational energy resulting in mechanical work.Small and medium steam turbines have wide range of applications in power generation and also as drivers for mechanical services. When these coupled with gear scan be used to drive fans and reciprocating compressors. Steam turbine finds many advantages than steam engine is discussed.

Multi Level Car Parking Polytechnic Mechanical Project Report

Introduction to Multi Level Car Parking Polytechnic Mechanical Project:

Increasing population is the most facing serious problem in our country. Today India is the second largest populated country in the world that is India having 16% of the world’s population.

When the last census conducted on 1991, 1st march, the country’s population was 846.30 million but currently country’s population estimated around 950 millions.

In the last 50 years the population growth has been increasing rapidly. This rapid growth in population is termed as population explosion.

The rapid growth rate in population is because in the recent times the industrial and technological revolutions had taken place.

By the beginning of the twenty first century, world population is estimated to reach 7 billion. Though several other countries experiencing population explosion, because of the increasing pressure on the country’s limited resources population explosion is major problem and much more severe in our country.

If the population increases then it mainly impacts the land. Day by day agricultural lands and forest areas become occupied by the people.

In offices and for big shopping complexes parking becoming a major issue. As the parking demand growing unexpectedly and significantly engineers are trying frequently to develop different planning strategies of parking.

If the surface area is not sufficient then modular steel car parks gives proper solution when multistory parking is unable to build.

With Modular steel car parking we can expand upwards. In this Modular steel car parking ceiling is made of concrete and tarmac and assembling vertical and horizontal elements in a modular way. With different sizes and shapes we can build more modular units of parking.

In this project of multi-level car parking we are going to give a proper solution for the parking of vehicles technique of Modular steel car parking and can be more useful for the complexes having small surface area.

Mechanical Project Report on Mobile 3D Visualization for Construction

Introduction to Mobile 3D Visualization for Construction Project:

Software named CAD in the past decades was used to create a 2D spectrum programs and conversion it to the 3D spectrum. The hardware used here to execute this program is the mainframes to the desktop of the system computers and the laptops. The storage of the system computers have now become an increment steps from the mega bytes to giga bytes too. Connections and communication between the servers and the computer has now advanced to the availability of the modems which allows us to access the internet service.

Now a day’s computers are made micro that it is also named as the Pocket Mobile Computers abbreviated as the PDA. Now talking about the hardware used here is the Windows CE operating system or the Palm computers. This PDA has a normally screen resolution as 240 X 320 pixels. This resolution has a limitation of 2D or 3D detailed information that can be displayed. Standard method of designing the data on computers where never a proper choice. While the devices like the Palm top has an 8 MB of virtual memory and other devices too have as their brands.

 The characteristics of the palm and the pocket pc are these both gadgets are similar in size and as well as shape too. These both can also be carried inside one pocket at a time. As like the desktops system computers this PDA also has a configurations of the hardware like the Processor type, Clock speed, storage space, peripheral interfaces etc… 

This device gives the graphics of the 3d View which can even be showed on the Pocket Personal Computers. These devices are developed by the CIS2 documents and files by using various protocols. These pockets PC are of limited size and which can also show a 3D view in the upcoming future days. In the next coming approximate seven to eight years it will made a experimental survey that will show  view of the PDA  at various sites.

Introduction to Micro Electro Mechanical Systems Presentation:

Micro electro mechanical systems which are abbreviated as the MEMS are the combination of electrical and mechanical devices and structures by the specific standard scale. The work of the MEMS is to perform the mathematical tasks which are critical for the conventional technologies. These devices are used in various other streams like automobile, medicals, aerospace’s, communication purpose and much more. The well know department called the NASA uses this technology at a very high scale.

Micro electro mechanical systems help in saving the power and also reduce the price which direct targets the advantage for the cost purpose.  These devices are mainly used in space craft’s where topic of temperature matters. There are three types of micro electro devices mainly the sensor, the actuator and last the smart MEMS. The sensor transfers the non electrical commands and codes to electrical output, and the actuator does the opposite of that of the sensor converting electrical to non electrical and the smart MEMS is the fusion of the electrical circuits.

 Some of the MEMS devices used normally are the Micro Heat Pipe which is used in space to give high temperature paths, Silicon Satellites which are which are also known as nano satellites which is used for constructing and testing the architectural design and development. Silicon satellites are more classified into the sub types named as the Micro satellite, nano satellite, Pico satellite and the Femo satellites.

 Micro electro mechanical system has now a day become the devices that keep the world in the development stages and for specially for the stream of science space and technology. In the upcoming future this MEMS will work on maintaining the protocols because it results to be the better device for such work purpose and also these micro electro mechanical systems will become very important in the need and use same like the random access memory chips used now a days.

Mechanical Seminar Topic on Spot Welding by Automation System PPT

Introduction to Mechanical Seminar Topic on Spot Welding by Automation System:

The topic is about welding, though there are different types of welding technique. Spot welding is more preferable.

  As the technology improves the robots are a head, we can use the robots for welding .this welding methods are done by using robots, and is called spot welding by automation system .The main equipment needed are A Robot controller an arc welding equipment Motion devices Robot motion Devices Sensors Safety Devices .As a robot is a technical device and we have to consider the following things while designing they are Robot work envelope, joints, travel velocity, Accuracy, and Resolution of motion.

CONTROLLER is called as a whole programmer. It can be considered as a brain of the human system, as it provides the signals by using high speed processors and sensors .The controller not only controls the robot but also many integrated parts such as manipulators. The mechanism is similar to that of a human body it means it controls all parts. The control system is so inevitable. Memory backup devices can also be using for giving data to it. It can be automated and the robot has the capacity to restore the data and loss occurs .it restores the data without return to the zero configurations.

NEEDS to generate arc: to maintain stability of power, short arc, a wire feeder to torch, cooling system

  Manipulators: it holds the device and moves with better access. The advantage is that they can be moved easily around the work piece for the best   welding positions, reduce the variation in the lead and the lag angles of   the tip a stable flat welding position  can be obtained, it increases the working range performed in a stable flat welding position, Any hard-to-reach positions can be accessed more easily.

Redesign Fuel filling System Project

Project Title: Redesign Fuel filling System

Project Description: COMPANY BACKGROUND:

TISS Security Systems are a Blackpool based company specialising in the design and manufacture of fuel security devices to prevent the theft of diesel from Truck Fuel Tanks. We are global market leaders, having sold over 100,000 units around the world. We are also worldwide sole suppliers of our products to 3 of the leading Truck Manufacturers: Iveco, Volvo and Mercedes.

The TankSafe product range consists of:

– TankSafe ‘Impregnable’ – the ONLY device in the world to completely prevent any siphoning, skimming and diesel spills

– TankSafe ‘Standard’ – world’s most effective basic anti-siphon at preventing 3rd party theft.

Please see the attached brochures for further information or visit our website at www.tissltd.com

THE PROJECT:

We are getting many requests both from existing customers and resellers and other prospective customers to supply devices to suit other Commercial Vehicles, specifically the Coach, Bus and Van markets.

We believe there is good scope for a project investigating and subsequently developing suitable devices for these markets. From an engineering point of view, these markets pose a number of new challenges; with Truck Fuel Tanks it has been relatively simple to develop suitable systems as once the fuel cap is taken off the tank you have direct access to the fuel. Bus, Coach and Van Fuel Tanks are more difficult, predominantly because their fuel tanks and filler necks are more similar to those of a car.

I believe this offers good scope for a project; with their university education, plus access to all of the resources at the University, I would hope that a student would be able to develop ideas for suitable systems. Some of the many things that will need to be considered for this project are:

– How to ensure the device fits in the filler neck in a secure manner.

– How to ensure the device fits inside the filler neck without impediment.

– How to ensure the device does not hinder filling speed or cause splashback.

– Ensure that the device does not impede the existing flap/cap on the filler neck or vehicle chassis.

 

Air muscle motor control project

Project Title: Air muscle motor control project

Project Description: The German company Festo has recently developed a range of pneumatic muscles.
Unlike conventional cylinders and pistons, they contract when filled with compressed air, generating much higher forces than the conventional components.
A motor test rig has been built using five of these muscles instead of pistons and cylinders. The air supply is controlled by a circuit and electrically operated valves.
The project is to complete or to redesign the circuit and program to make the motor work, and then to, modify the characteristics to understand and to optimize the performance.

Product Details: The project will lead to a working control system for the motor. Provision will be made for adjustment to the timing of the inlet and exhaust functions. Measurements will be made to assess the performance and to establish optimised performance.
