The structure and characteristics of the compass of the yacht magnetic compass.
May 02, 2022| The yacht magnetic compass is mainly composed of a compass basin, a compass cabinet and a self-difference corrector. Today, let me introduce to you the structure and function characteristics of the lower compass basin.
The Luopen is mainly composed of the Luopen body and the compass.
ONE. Luopen body
1. Generally made of copper material.
2. Liquid injection hole: It is used to eliminate air bubbles in the basin.
3. Baseline: The first baseline is used to read the course of the ship.
4. Luopen liquid: 45% alcohol + 55% distilled water mixed liquid, the function of alcohol is to lower the boiling point
5. Measures to prevent the liquid from thermal expansion and contraction: ①The bottom of the basin is made of copper corrugated sheets; ②The basin is divided into upper and lower chambers, which are connected by capillary tubes, and are adjusted by the pressure in the basin.
6. In order to ensure the stability of the lubricating basin, it is necessary to lower the center of gravity of the lubricating basin, increase the counterweight at the bottom of the lubricating basin, and place it on the gimbal ring.
TWO. Compass
The compass is a sensitive component used to indicate the direction, and there are 0-360° scales and direction points on the dial above. The center of the shaft cap is embedded with gemstones, and the shaft is made of hard metal such as iridium, which can reduce friction with the shaft cap.
