Acquisition demand structure speck f 4200. 1. 2 cg-business providers MPC-PMS detail guidance card E. †A-M-3356(A=auxiliary M=monthly 3356=identification number) M-primary impetus apparatus An assistant E-electrical R-harm control NEM-m9000. 6 ELC site - present a change Engineering dept will keep up single tag-out log Tag out-comdtinst 9077. 1 * Check and reviews once at regular intervals by i nsightful dept * Tag numbers will begin once again OCT 1 * Size of the vessel decides the quantity of tag-out logs required * Replacing a missing tag-next consecutive number on tag out sheet * Check effectively introduced visual think about tag out record sheet and label review Recommend change in PMS strategies must: In composed structure * Given to the PSM facilitator FPD( budgetary and obtainment) gives acquisitions and bookkeeping First quarter-is oct-dec Take material from stock you should do an underlying solicitation Tachometer-is an instrument that produces, transmits, and shows information that is changed over into an estimation of revolution speed Verify perusing against data found on nameplate information 4 sorts of Tachometer: 1. Chronometric Tachometer, open shaft, press and discharge start button, shows after 5sec 2. Outward tachometer, nonstop perusing of rpm’s on available shaft 3. Thunderous tachometer, vibrating, when shaft isn't available 4. Photograph electric tachometer, battery worked, non-contact(place intelligent tape on shaft Calibration done-12 to year and a half, sticker has last adjustment and due date Frequency = number of cycles in a given time F (Hertz) = number of posts X rpm/120 Rpm=120 X f/no of shafts Transducers Pressures Transducers-convert pressure into an electrical yield signal that is proportionate to the information pressure. Continuously get consent before investigating, disengage from the pressurized framework Replace with same kind or a higher evaluation King nutronics-2250 psi Uses 4-20ma so it travel longer separations Don’t zero and range to repay perusing Easily controlled Prone to obstruction Troubleshooting-confirm transducer is the issue Resistance Temp Detector RTD (opposition temp locator) temp sensor whose electrical obstruction changes directly with change in temp RTD is associated with wheatherstone connect Two components with isolated temp measure 1. Nickel: - 40 to 1000 degree for all setups 2. Platinum: - 40 to 1000 degree for thermowell, exposed bulb and installed design Two wire detecting component: red and white * needs remuneration circuit Three wire detecting components: 2whites and red* no need pay Three sorts of RTD setups: 1. 5sec. installed( oil film temp in hardware bearing) 2. 8sec. Thermowell ( high weight) 3. 15sec. Exposed Bulb legitimately submerged in high weight gas Thermocouple is gadget to quantify temp as temp changes an electrical potential in MV is produced Used in pyrometer Air temp change in a cool intersection will cause mistaken understanding Cleaning: affirmed dissolvable, checking free or messy association, adjustments UAW tech manual by makes Two unique metals that is alluded as HOT JUNCTION(thermocouple sensor) Two divergent metals become comparable is Cold intersection (reference intersection) Two kind of therocouples 1. Type K, chromel(+yellow) Alumel (- Red) 2. Type J, Iron (+white) constantan (- Red) Synchro Two kinds of damping techniques: 1. Electrical 2. Mechanical Most elevated estimation of powerful voltage instigated in one stator curl is 52v Rapid and precise transmission Electromagnetic enlistment Two general arrangements: 1. Troque - moves light loads like dials 2. Control - substantial burdens weapon executives Two basic synchro rotors or windings: 1. Remarkable shaft rotor 2. Drum or wound rotor Synchro looks like little electrical engine works like a variable transformer NEVER associate 400hz synchro to 60hz voltage Operating voltage and recurrence is mark on name plate Military norm and naval force prestandard synchros-115 vac or 26vac Load directs the sort of synchro and framework By switching s1 and s3 both synchro engines turn a similar sum, in inverse headings Change S2 causes 120 degree blunder †it inverts the bearing Oscillation and turning of the pointer: 1. Stator winding are shorted 2. Imperfect damper Reversal R1 and R2 180 degree blunder †pivot continues as before Damping circuit forestalls gear train motions or turning Common focusing techniques: 1. Air conditioning Voltmeter strategy( generally precise) 2. Electrical-lock( quickest) Rotor gets voltage by essential winding â€Å"excitation† Stator gets voltage from the Rotor by attractive coupling GYRO Heading, roll and pitch Transmits information to weapons control, sonar radar, profundity control, dead retribution Gyrocompass has two essential properties: 1. Unbending nature in space(rigid, no power) 2. Precession(right edge, applied power) MK27: 1. Comprises of ace compass, electronic control unit and force converter 2. Looks for genuine north 3. ECU-working control->servo Amplifier->alarm Circuitry->power gracefully >latitude control hardware 4. S-1 switches-Slew, Start, Run-manual or auto 5. E-center pickoff-produces signal from corresponding to gyro from invalid 6. J3 test focuses ace compass 7. Full wave connect rectifier â€rectifies AC to DC 8. Stifle input channel >creates smooth DC voltage Anemomter Wind direction(HD) and speed(HE) marker comparative with ships heading and speed Wind speed pointer visual sign of wind speed and direction(single stage 115vac) Voltmeter is utilized with anemometer Wind speed indicator(HE) transmits signal voltmeter(magneto) Capacitor forestalls RF obstruction or lessens stator flows Set discharges RF impedance: flawed capacitor at back, swap for magneto Remove 2300 ohm resistor from the two sides when utilizing to markers Salinity New water defiled abundance of 0. 25 grains of ocean salt per gallon alert will go off (audio&visual) After the solenoid is de-empowered it must be physically reset Dumper valve solenoid de-invigorated when contaminations arrive at caution extents occupying water over the edge Cell test resistor-little compact unit with contact fingers System test and cell examination > month to month Inspection-> every other month Thermistor-> temp touchy resistor which limits ebb and flow stream over the hole between the plates Salinity Module test/establishment > 23 vac across tp1-tp2 holes shorted cell/wiring ciruit VLA) Visual Landing Aids Helo deckarea marker-Lighting-Approach helps Wave off lights-prompt to steer landing is inadmissible Wave-off light won't quench when wave-off switch is made sure about order is being sent from remote board Homing reference point - >white light >main pole >flashes 90x per min Lamp circuit-wired: advance down transformer(115/32 volts) t o variable diminishing circuit Line-up-lights-20 lights-white and glimmer in arrangement uni or bi-directional VLA power prerequisites lighting framework 120v/60hz WIPER Window wipers-DC voltage, taking 115vac single-stage utilizing full-wave connect rectifier Oil to outside oil cup lubs the brushes Replace at regular intervals or two times each year Life length is one year Drive component changes over the revolution of the engine to go to and fro Pendulum window wiper-wiper change to stop (to put wiper out of view) Steering To decide rudder rate a HARD-OVER-TO HARD â€OVER order is given while transport is moving in max speed. Overtravel-is a directing situation on rudder past the request point and stays at that position Overshoot-not many degrees past the more established edge yet comes back to the request edge Three methods of activity of guiding framework: 1. Follow up 2. Auto pilot 3. Non follow up Four segments: 1. Pressure driven framework water driven force units and rudder actuators 2. Crisis gear 3. Rudder position criticism framework 4. Directing controls Control circuit-produces an electrical sign to move the rudder Hydroulic power unit(HPU) ports pressure driven liquid to the Actuator transforms pressure driven force into mechanical movement Steering power of water following up on the rudder Solenoid valve-controls water driven liquid to the actuators-> to move rudder Utilizations power through pressure to control rudder as a result of the high torque â€to-weight proportion Maximum blunder permitted on rudder edge is + or - 2 Battery Normal temp-80f degrees Initial: a low-rate charge given to another battery Normal: Routine charge IAW nameplate information Emergency: a quick or lift charge Equalizing: broadened typical charge given at a particular gravity Floating: voltage kept up inside the cutoff points
