What is the circuit for shaping machine?<br />Quick Return Motion Circuits.<br /><br />35. What is automatic sequencing circuit?<br />By sequencing a number of pneumatic cylinders, various machining and tooling<br />operations may easily be obtained in a machine. By using this technique, the cylinders can be<br />actuated one after another in sequences like clamping, feeding and ejecting (or) lifting,<br />pushing and clamping (or) in various other combinations. The pneumatic circuit utilizing this<br />technique is known as automatic sequencing circuit. Correct sequence of motion of each<br />cylinder and the respective cycle time, should be carefully studied before designing such a<br />circuit. <br /><br />36. What is a sequencing circuit?<br />Process control pneumatics is also called as sequencing. It means performing number of<br />actions one after another which follows each other in a simple order or with an order<br />determined by sensors.<br /><br />37. What is pneumatic direction control valve?<br />Pneumatic direction control valve is used to control the direction of air path. These<br />Valves have generally two, three, four (or) five ports: These ports are designated as<br />P: Compressor line port<br />R: Exhaust port (T is case of hydraulics)<br />A, B: Working ports connected to actuator.<br /><br />38 What is the use of Time Delay Valves?<br />Pneumatic time delay valves are used to delay operations where time based sequences<br />are required. <br /><br />39. What is a fast exhaust valve?<br />A fast exhaust valve is used to vent cylinder quickly. It is primary used with spring<br />return (single acting) pneumatic cylinders.<br /><br />40. Differentiate between hydraulic and pneumatic systems?<br />The working fluid of hydraulic system is water (or) oil (or) any liquid.<br />The working fluid of pneumatic circuit is air Hydraulic systems are designed for heavy loads<br />where as pneumatic systems are designed for low (or) medium loads.<br /><br />41. What is the function of pneumatic circuit using quick exhaust valve?<br />By quickly exhausting the air from the cylinder, the cylinder speed can be exhausted.<br /><br />42.What is Time delay circuit?<br />In certain applications, the impulse to the main direction control valve may have to be<br />delayed to pre-determined time for different operational reasons. A pneumatic time delay<br />valve may be used in such cases. A pneumatic circuit using this time delay valve is known as<br />time delay circuit.<br /><br />43. What is the use of compressor?<br />A compressor is a machine, which compresses air (or) any other gas from atmospheric<br />pressure to a desired higher pressure level.<br /><br />44.Name two basic types of compressors?<br />1.Positive displacement compressors<br />2.Dynamic (Turbo) compressors.<br /><br />45. Differentiate between single acting and double acting compressors.<br />In a single acting compressor, the compression takes place 011 one side of the piston<br />for each revolution of crank shaft.<br />. In a double acting cylinder, compression takes place on both faces of the piston giving<br />two compression strokes for each revolution of the crankshaft.<br /><br />46. Define FRL unit?<br />Air is not clean and hence contamination may result in pneumatic circuit. Also, due to<br />time fluctuations, the receiver air pressure does not remain constant. Also, some parts of the<br />pneumatic system have to be lubricated for proper maintenance.<br />For cleaning the air, regulating the pressure of air and lubricating pneumatic parts, three<br />units 'Filter - Pressure Regulator - Lubricator' (Trio unit) are put together and this combined<br />unit - Trio unit - is called FRL unit.<br /><br />47. Explain Fluidic Logic Control?<br />In many plants, closed loop control is achieved by electronic devices based on<br />different logic functions such as AND, OR, NOT and MEMORY.<br />Logic controls can be defined as design of control system based on reasoning arising out<br />of deductive principle. However, the electronic control system is not only control system used<br />in industries. If the pneumatic control system using low-pressure air is used to achieve the<br />above logic control functions, then it is known as Fluidic Logic Control.<br /><br />48. What is fluidics?<br />Fluidics is the technology that utilizes fluid flow phenomena in components and circuits<br />to perform a wide variety of control functions including sensing, logic and m more functions.<br /><br />49. How pump cavitation is identified?<br />Cavitation is the inability of a pump to draw a full charge of oil either because of air<br />leaks or restrictions in the inlet line. When a pump starts to cavitate, its noise level increases<br />and it may become very hot around the shaft and front bearing. Other symptoms of cavitation<br />are erratic movement of cylinders, difficulty in building up full pressure, and a milky<br />appearance of the oil.<br /><br />50. Write about leakage testing of air cylinders?<br />Piston seals and rod seals become worn to the point that cylinder performance (or)<br />I efficiency is affected. Leakage around the rod seal can easily be detected and the seal can<br />be replaced. At that time, the rod bearing which is usually brass, bronze (or) Teflon,<br />It should also be replaced.<br /><br />51. What is air receiver?<br />Air receiver is a large cylindrical vessel used to store high pressure air from the<br />compressor. Large surface area of the receiver dissipates the heat of compression (heat in the<br />compressed air) to the surrounding atmosphere. It will have safety relief valve, pressure<br />indicator and temperature switches.<br /><br />52. What are the advantages of fluidic elements?<br />a. No wear and tear of elements.<br />b. No actuating force is needed.<br />c. Very little space needed for mounting.<br />d. Insensitive to noise, vibration, temperature, electric noise and radiation.<br /><br />53. Name the common methods used for designing logic circuits?<br />a. Cascade method<br />b. Classic method<br />c. Step counter method<br />d. KV map method<br />e. Combinational circuit design<br /><br />54. What is the difference between pressure switch and temperature switch?<br />Pressure switches open and close contacts based on the system pressure.<br />Temperature switches senses change in temperature and open and close contacts when<br />a predetermined temperature is reached.<br /><br />55. How does a limit switch differ from a push button switch?<br />Push button switches make or break contact only as long as they held pressed.<br />But limit switches make or break contact permanently when they are actuated.<br /><br />56. What is an electric relay?<br />Electric relay is a switch whose contacts open or close when its coil is<br />energized. Relays are used for energising and de-energising solenoids.<br /><br />57. What is ladder diagram?<br />The ladder diagram is a representation of hardware connections between switches,<br />relays, solenoids, etc. The left leg of the ladder connected to the power and right to the<br />ground.<br /><br />58. What is the advantage of using micro electronic control for fluid power compared to electro mechanical control?<br /><br />When the sequence changes, the hard-wired electro mechanical has to be changed.<br />This is expensive, but micro electronic control is programmable. So when the sequence<br />changes, the program only has to be changed.<br /><br />59. What is PLC?<br />PLC is a digital electronic device that uses a programmable memory to store<br />instructions such as logic, sequencing, timing counting and arithmetic to control<br />machine or process. <br /><br />60.What are the basic elements of PLC?<br />(i) Central processing unit with memory.<br />(ii) Input modules.<br />(iii) Output modulesUnknownnoreply@blogger.com0tag:blogger.com,1999:blog-8024952236071513501.post-75211762511916577332011-11-08T07:56:00.000-08:002011-11-08T07:57:46.600-08:00CS2401 computer graphics question bank<b style="color: blue;">CS2401 QUESTION BANK | DOWNLOAD</b><br /><br /><br />QUESTION BANK<br />UNIT- I OUTPUT PRIMITIVES<br />Part-A (2-MARKS)<br />1.
