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.

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, 1^st 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.

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 Real Time Sequence Control System For Machines Project:

The Real time, time sequence control system for machines is a project used mainly in the industries.

 It can also be used for home appliances for automatic Switching on and off of any machine.  In real life to switch on and off machine at a particular time the event management system can be used. If the number of devices increases, the job is little bit complex. So we can design an event management system i.e. real time sequence control system for machines. The RTC works in   real time. The switching on and off time of each machine is set by using micro controller  Relays are used to connect device to the micro controller.                          

The technology used in the system is Automation of machines. Automation is a the process in which a particular programming is given to it to run in a particular way so that it works in that way automatically

The software and hardware used are Embedded C, Micro controller Hardware, in   40 %  and 60 % .

The main components used in it are 1) Power supply2) Micro controller 3) LCD 4) Real Time Clock (RTC – DS1307) 5) Buzzer 6) Relay: 7) SWITCHES:

The micro controller controls all the mechanism the voltage regulators are used in power supply. Micro controller used is the AT89S52 is a low-power, high-performance programmable Flash memory. The Led is used to display all the contents in brief, Real time clock is used to maintain a time limit for on and off Buzzer indicates on and off status of a machine Relay is used to on and off which is controlled by micro controller .The switches are visible devices by which we can control many operations.

Application:  the application of the system is mainly in industries to operate many machines and in controlling different machines

Conclusion: We can use remote controller instead of switches in each and every operation for the easiness and other safety purposes.

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.
