Because turbochargers often work in high speed, high temperature, Marine electrical and mechanical supercharger exhaust turbine in 700-900 ℃, the temperature turbocharger rotor with tens of thousands of turn to turn more than twenty high speed rotating, so in order to guarantee the normal work of the supercharger, in use should be paid attention to the following:

You can't just drive away

After the engine is started, especially in winter, it should be idle for a period of time so that the bearing can be fully lubricated with lubricating oil before the turbocharger rotor runs at high speed. So just started after the accelerator must not slam, in case of damage to the supercharger oil seal.

Do not extinguish immediately　　

Qingdao ship mechanical and electrical engine captain time high speed operation, can not immediately shut down. When the engine is working, a portion of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling. After running the engine suddenly stop, oil pressure rapidly reduced to zero, the supercharger turbo spread to middle part of the high temperature and bearing shell heat cannot take away quickly, while the turbocharger rotor was still under the effect of inertia at high speed, therefore, if all of a sudden stop, the engine heat engine condition will cause the turbocharger stranded within the oil overheating and damage of bearing and shaft. In particular, to prevent a few hard shots after the accelerator suddenly flameout.

Keep clean

The ship mechanical and electrical demolition supercharger, to keep clean, all pipe joints must be plugged with clean cloth, prevent debris into the supercharger, damage to the rotor. The impeller shall not be damaged by collision during maintenance. If the impeller needs to be replaced, it shall undergo dynamic balance test. After reloading, remove the plug.

Because the supercharger often operates at high temperature

Its lubricating oil pipeline is affected by high temperature, the internal oil is easy to part of the coking, which will cause insufficient lubrication of the turbocharger bearing and damage. Therefore, the lubricating oil pipeline should be cleaned after running for a period of time.
