Answer 1

DATE 1 Pump - power into pump is the deviu. which con mechanical hydraulic power by pressuring Jump is the beast of hydraulic system the oil 2. Pressure Guages - It donates pressure: the system oil 8 Pressure Relief valve - It is used to relive excess pressure of the system 4 Direction control valve - It is used to control the direction of oil flowing through system provided to Dc valve 5 Push button - Button is to operate its direction 6 the pressure Spring The symbol shows that is adjusted by mean of spring. 1 It is used poured the oil Tank Cap into system 8 Tank - It is used to store the oil.ro 1 Input line - Pump sucks It is connected to pump with filter. the oil from tank through this input line. NO Diverting set this directing line. Hine - pressure, then When system pressure increases than extra pessur oil is passed through

| DATE By using this spring ayir Yariable pressure adjusted spring we can adjust the pressure of oil. Actuator 1- Single: acting spring operated vyunder Also called End effector. 12 ad 13 spring Omates side of pisten 14 pressurised oil is il Retum line - reigh supplied to tank. 15 End effector - Work is done by the system by moving by moving actuatori Return line from actuates & When piston moves backwald out throug this return and goes to tank. comes flow in 17 check valve & This valve allows the one diriction only. 081 part of a 4.

PAGE No. IDATE 88 false, The circuit has Actuator output element. As it has single operated spring loaded påstom f cytunder arrangement. So To and fro motion It will have only the 89 Yes Infact DC valve shown in diagramis 3/ DC operated valve. Ime for single acting cylinder always volve. we use 90 Ye PRV can be removed, but if the system pressure continueewly increasing then it will be harmful system will have damage with large vibration Temperature of oil can also increases which its fire hazardous to system. So the question would be false against safety 9L false The retention of the pistore without would not be spring done work contineonly. It will work only at onie It will not and position 92 False . By removing check valve the back flow will be there of Dc valve. so the pressure will increased. and it is desirable. not 93 we If then replaced PDP with swast place pump system will have large vibration. And discharge of swath flak pimp is continews Discharge is fluctuating

PAGE No DATE 94 If the pressure on both sick of valve jo Scome then there will be no How of oil from the valve.al
