GYRO COMPAS
Azaz: similar will repel, which will pull different ie the north magnetic pole and south magnetic poles.
Compass kettle, there are two, namely: Wet and Dry
- Wet contains a solution of 30% alcohol and 70% distilled water.
Usefulness tersbut solution is for shock absorbers.
The condition is that the material is free of iron means thirsty aluminum.
How to check: the way the dish will quickly swung back its original position.
Compass storage method:
- Put into a special box and should be soft pads.
- Free from vibration means vibration of ship engines.
- Each will be used means that if the ship will sail always be corrected atinya APPOINTS ONE (ST)
LINE SCREEN:
- The location of the line of the screen should always be in front of the circle in the kettle
- must be parallel to the keel
- Baring fore one of the mast.
- plane center point lying: it means the locus pijera lat gap for membaring
Ring-Hoop:
- each disc sits on the ring
- To remain closed pijera gap
Terms-of Personality KETTLE:
- Bolh not contain magnets.
- Glass lid must remain in the flat state.
- If the boiler will not swing menuyentuh anything.
- Berdir Tuntung fixed pin in the middle.
- Line screen should remain in place.
Things that need dipehatikan:
- Fluids should be in a state of full kettle
- The float must be watertight.
- Guidelines wet mounted on Ring Hoop.
SENSITIVE:
If the disc dikluarkan of position then he should quickly return.
COOL DOWN:
If the disc is interrupted by outside influences, then he can not quickly swing.
Example:
- Influence by rocking the boat
- Vibrations aboard the ship backwards time machine
- Ship turnaround.
One of collimation;
When you have a deviation angle axis magnetic needles roses with roses line the US guidelines.
Errors of the magnetic guidance as follows:
1.eror own
Ie if the US does not coincide with the magnetic axis guidelines
2.eror from outside
The influence of body magnitterhadap ship / metal that affects the magnet.
The means test CALM:
- Rotate the dish with a small angle
- Remove and read his appointment
Turn the opposite direction, separated continue reading = 1-2 = 1/2 (quiet)
Enterprises enlarge SENSITIVITY:
- Large magnetic moment
- Heavy disc SMALL / LIGHT
Gains and Losses guidelines for liquid and dry
LUCKILY:
- Because there is pressure, vibration can be muted sehinggan nand pin sangkup not wear out quickly.
- Can be made more sensitive and quiet
- If there are outside influences aside quickly and after the effect is lost right back its original position.
Disadvantages:
- Often arise glembung-bubble
- At the time counterbalance the guidelines will be very difficult
CAUTION:
- Prohibited from carrying a kettle with a dish sitting on hook
- At the time of installing a new pin between the old and new the same height. Because the glass lid will ncepat damaged.
GUIDELINES GASING (GYRO COMPASS)
Definition:
Gyros which means;
spin
Skopein which means seeing) see the earth spinning. Theory of a French sarjanadari
An object that can be rapidly rotating rpm.6000 x. Surrounds the shaft and can berpyter free 3-way.
Terms Gyroscope:
- Reseltante all styles must rely on gravity top
- Third shaft should stand perpendicular to each other.
- The third axis intersect at the point of a top heavy.
Type guidelines GASING:
- Sperry (USA)
- Brown (Ing)
- Anschuts (Jer)
Some of the advantages of the Guidelines Gyro:
- Direction is always true
- Readings very carefully, enlargement rose pedman Steering meticulous = up to 1 degree
- Installation Repeater, L / R outside the pavilion so that the horizon is free.
- At the time the ship swerved, helmsman see fast turnaround.
Disadvantages of using Pedman Spinner:
- Installation is very complete and very expensive.
- The arrangement is also very complicated, if there is a change in the power generator and decrease the voltage designation guidelines direction going awry before the normal voltage
- If there is damage at sea is difficult to repair because their experts on the ground
STEERING ARRANGEMENT
Consists of:
- Penatan steering wheel
- Successor to the steering wheel to the steering driving machine
- Clutch in motion successor
- Driving machine leaves the wheel
REQUIREMENTS ON PASSENGER SHIP:
- Must be cikar 35 Ka / Ki with full speed within 28 seconds. Ki 35 - Ka 30.
- Emergency steering with power
- If the boat with twin engines are not required any emergency steering.
CATEGORI TO SHIP GOODS:
- Pangsi or double hinge with a diameter of 14 inches. Emergency steering with power allowed.
- Same with no.3 on passenger ships
ARRANGEMENT STEERING AND POWER DRIVER
- Hand
- Steam power
- Power
- Power hydraulis
Drifting:
Angle changes that occur between the meridians of the earth with the axis of the gyroscope in the horizontal direction caused by the vertical component of the earth's rotation
Position the tip top of a gyroscope axis views of the earth's rotation.
Gyroscope can not be used as a guideline for:
- The weight of tops is not possible precisely arranged on the shaft
- If a top foreign body touched the shaft will be pointed in the other direction
- Foreign shaft is not sitting in the direction of the US but it would spin
ERROR ON GUIDELINES GYRO:
1.Course and speed error depends on:
- Latitude overseers
- Course
- Speed boat
2.Error reduction
- Depending on the overseer, a fixed value for all bow
Due to the sudden change of pace.
How to eliminate it as follows:
- Gyro hung on a horizontal azis
- Gyro dibalance each semester.
4.Error swing
Action to prevent it:
- Sensitive element must balance.
- HG narrowed connecting pipe.
- At the top of the vessel given ballast.
- Spider hung with oil cylinder.
