The main factors that cause diesel engines to "burn oil" due to Yuchai generator set maintenance are:
1. Cylinder liners and piston rings are seriously worn due to some reasons (these reasons; include: running-in Due to insufficient experiences, this uninterruptible power supply product is highly praised by industry insiders in many regions and industries;
2. The product market is large. Initially, it was thought that the piston rings and cylinder liners were badly worn, but when disassembling the cylinder, the piston. been found. The cylinder rings and liners are normal;
The generator set maintenance company reminds you when the temperature in the filter reaches 350°C, the deposited particles will oxidize and. will burn If the temperature does not reach 350°C, too many deposits will clog the filter.external energy (such as electric heaters, burners or changes in engine operating conditions). ) is necessary to increase the temperature in the DPF to oxidize and burn the particles. Passive regeneration refers to the use of fuel additives or a catalyst to reduce the ignition temperature of particles.
Common problems in using. Yuchai generator sets
1. Multi-phase short circuit of stator winding
Multi-phase short circuit is the most harmful to the generator and short circuit current. will cause the generator to burn.
2. Single-Phase Grounding of Stator Winding When a single-phase ground fault occurs in the stator winding, the current flowing through the stator core will cause the breakdown. core to burn or even partially melt the core
3. The excitation circuit is set toGround
There are some situations in which the excitation circuit is grounded during maintenance of the Yuchai generator set. two types: grounding and two-point grounding. Generally speaking, when a grounding point occurs in the excitation circuit, the Yuchai generator will not suffer any serious damage. However, if not treated in time, it may cause two-point grounding. grounding and destroys the rotor flux balance, causing strong generator vibrations and eventually burning the rotor winding
