Excavator repair engine white smoke first to see whether the excavator engine water temperature is too low caused.
Then see if the excavator injection advance Angle is too small, atomization is not good. The poor quality of diesel used in Kobelco's excavators may also be to blame.
So what to do when the excavator engine white smoke failure?
First of all, check the water temperature of the hydraulic excavator engine. Under normal circumstances, if the engine water temperature is too low, the temperature in the combustion chamber will be relatively low, so that the diesel oil will be poorly atomized after entering, and some of the poorly atomized diesel oil will be gray and white with the gas discharge, and the excavator white smoke fault will occur. Therefore, when the excavator is operating, it is generally necessary to idle the excavator engine for 3-5 minutes, and then work at the fuel door, so as to avoid the occurrence of the Kobelco SK480LC-8 excavator white smoke fault.
After the occurrence of the white smoke fault of the excavator, the injection advance Angle of the mountain heavy excavator should be checked in time, and if the advance Angle is too small, it should be adjusted. In addition, the excavator should select and add diesel in strict accordance with the provisions of the instruction manual in the daily operation to prevent excessive moisture in the diesel and avoid the occurrence of the excavator white smoke fault.
What is the cause of black and white smoke from excavator maintenance?
1. the white smoke is generally the water in the cylinder will appear. The white smoke from the excavator may also be the wrong ignition timing, the black smoke may be the diesel filter and air filter is dirty, and these situations may occur if the diesel oil is not pure
2. this situation is generally a problem with the cylinder pad, resulting in the cylinder, oil passage, watercourse between the seal is not tight, when the pressure is too large when the oil or water into the cylinder to participate in combustion. When the oil enters the cylinder and burns, black smoke is emitted, and when the water enters the cylinder and participates in the combustion, white smoke is emitted.
3. the large excavator nozzle atomization is not good, first change the nozzle to see in saying, it is possible to change the nozzle or smoke, that is, the pump plunger wear after the high pressure lower top does not move the nozzle, then the school pump is good, so the maintenance will delay a lot of time, generally speaking, the nozzle and the injection pump together to school more simply a success.
