Since the supercharger is mounted on the exhaust side of the engine, the operating temperature of the supercharger is high and the speed of the turbocharger is very high at the time of operation, which can reach tens of thousands of turns per minute, The temperature makes the common needle roller or ball bearing can not work, so the turbocharger generally use full floating bearing, from the oil to lubricate, cooling. So for this structural principle, the use of this engine should pay attention to some of the problems:

1) When the downtime is too long or during the winter, and when the supercharger is replaced, the supercharger shall be pre-lubricated.

2) the engine should be idle after running 3 ~ 5min, so that the lubricating oil to a certain working temperature and pressure, so as to avoid a sudden increase in load due to oil without oil and accelerated wear, or even stuck.

3) When the vehicle is stopped, do not turn off immediately, should run idle for 3 ~ 5min, so that the superheater rotor temperature and speed gradually decreased. Immediate flameout will cause the oil to lose pressure, the rotor will be damaged by inertia and not lubricated.

4) often check the oil oil, to avoid the lack of oil and lead to Baotou North Ben heavy truck parts bearing failure and rotating pieces stuck.

5) regular replacement of oil and machine filter, due to the full floating bearing on the high requirements of lubricants, manufacturers should use the brand name oil.

6) regular cleaning replacement Baotou North Ben heavy truck accessories air filter, air filter dirty will cause increased intake resistance, the engine power down.

7) Always check the airtight system of the airtight, leakage will make dust into the supercharger and engine, damage the supercharger and engine.

8) Bypass Valve Actuator The pressure setting and calibration is carried out on a special setting / inspection body, and the customer and other personnel can not change at will.

9) Because the turbocharger rotor bearing high precision, maintenance and installation of the working environment is very strict, so the supercharger failure or damage should be to the designated service station for maintenance.

In short, the user must be strictly in accordance with the requirements of the operating instructions for the correct operation, as much as possible to play the role of three major lubricants (lubrication, decontamination, cooling), try to avoid man-made, unnecessary failure caused by supercharger Damage and scrapped, so as to ensure that Baotou North Ben heavy truck accessories supercharger should have the service life.
