Classification Thiab Inspection Method Ntawm Marine Magnetic Compass.

Ua ntej, Marine magnetic compass classification
1, raws li kev siv thiab kev teeb tsa txoj haujlwm:
1) Tus qauv compass: qhib sab saum toj lawj, nkoj sib nqus lub zog me me, pom kev zoo.
Siv lub tshuab refraction lossis cov cuab yeej ntsuas los tso cov dials thiab cov hauv paus
Reflected rau hauv tus choj rau kauj.
2) Steering compass: kauj log pem hauv ntej, kauj.

3, raws li kev faib ua kua: 1) kua compass; 2) Qhuav compass

Qhov thib ob, xyuas qhov rhiab heev ntawm Marine magnetic compass: xyuas los ntawm kev ntsuas lub stagnation Angle. Kev kuaj xyuas yog raws li hauv qab no:
1, tej yam kev mob: lub nkoj yog tsau ntawm qhov chaw nres nkoj, lub nkoj ntug hiav txwv machinery tsis ua hauj lwm thiab lub deviation tsis loj;
2, sau cov nqi kawm kom raug;
3. Siv cov hlau nplaum me me los yog hlau kom deflect lub compass 20-30 mus rau sab laug (txoj cai) thiab tshem tawm sai sai;
4. Tom qab lub compass rov qab mus rau qhov sib npaug, qhov sib txawv ntawm cov ntawv nyeem thiab cov nqe lus tseem ceeb yuav tsum tsawg dua 0.20;
