Diesel generator set "burning oil" refers to the lubricating oil in the lubrication system of the unit entering the cylinder and participating in combustion. Burning oil not only increases the fuel consumption of the unit, but also leads to insufficient combustion of the engine oil. Over time, it can cause a large amount of carbon deposits, affecting the power performance of the unit. Therefore, when we find that diesel generator sets are burning oil, we must deal with it in a timely manner. Below, Top Power will introduce the 6 reasons why diesel generator sets are burning oil. 1. Too much oil in the oil pan   Some users have inserted the dipstick incorrectly and failed to seat it to the bottom, resulting in the measured oil level being lower than the actual oil level. Therefore, they need to add new oil, causing the oil level to be too high. If the bottom end of the connecting rod of the high-pressure lubricated engine touches the oil surface, or if the oil ring of the spla...

In the AC circuit of a silent generator set, a pure resistance circuit where the current and voltage in the load are in phase and can cancel each other out. The method of paralleling capacitors on the inductive load of a silent generator set can compensate for the reactive power of the inductive load by the reactive power of the capacitors, thereby reducing or even eliminating the original energy exchange between the inductive load of the silent generator set and the power source. Most of the loads in the power system are inductive, so the total current will lag the voltage by an angle, and the   silent generator se t's parallel capacitors will be connected in parallel with the load. The current of the capacitor will offset a portion of the inductance current, thereby reducing the total current and increasing the power factor. Insufficient cooling water in a silent generator set can reduce its cooling effect. Silent generator sets overheat due to ineffective cooling, and high oil t...
