2 inch marine tachometer

• 2022-06-28

Our company can provide 2 inch marine tachometer , the 2 inch is 52mm size . The tachometer is first used to check the idle speed, that is, after the water temperature is normal, the idle speed should generally be about 800-1000 rpm . The second is the reference of shift timing . Generally, it is controlled at about 2000 rpm to shift in time . If the speed is too high , it will waste oil . If the speed is too low, the marine will lack power.

Why is there a 2 inch marine tachometer on the dashboard ? Why do most people still put the tachometer in a prominent position when they only pay attention to the tachometer , and some ships marines even highlight the tachometer ? This shows that it is very important ! So what information can the tachometer give us ? How can we make good use of this information ?

Although the speed is only a parameter of the engine, as in the above scenario , the tachometer can convey many important information : indicating the operating status of the engine , indicating the safe operating area of the engine , and identifying and labeling .

At too high speed , the lubrication and heat dissipation effect of the engine is poor . If the rotating speed is too high and exceeds the bearing capacity of some engine parts, these parts will be damaged. Therefore , the tachometer of early marines was equipped with a red line area to remind the driver . At this time , the engine is working in an unsafe area . If the waves continue , the engine will be lost .

Up to now, all ships have been equipped with tachometers, even electric marines with engines . However , the tachometer can still be used as an identification tag . For example , the red line mentioned above can be said to have lost its original function of indicating unsafe working areas , because the current engine control technology will be equipped with speed limit function , which will not allow the engine to run to this unsafe area . The red line can be said to have degenerated into habitual signs and labels .
