Diesel Generator Tech

The main reason why the diesel generator set fuel injection pump does not supply oil 1. There is no oil in the fuel tank or the oil switch is not open. 2. The diesel filter is clogged. 3. There is a lot of air in the oil road. 4. The plunger of the fuel injection pump is broken. 5. The plunger couple is excessively worn. 6. The plunger is stuck. 7. The screw groove of the plunger is installed in the wrong position. 8. The oil outlet valve is excessively worn or dirty. 9. The spring of oil outlet valve is broken or the spring force is weakened. 10. The plane contact between the oil outlet valve and the plunger sleeve is not strict, which causes the diesel oil to leak from the gap in the contact surface. The fuel valve is not opened at the top and the fuel injection pump is not supplied with oil. 11. The oil outlet valve is broken. Inspection method: If all cylinders do not supply oil, the diesel engine cannot work. If the individual...

A fuel water separator is a device that works to ensure clean fuel is delivered to the engine. Properly speaking, a fuel water separator is a small filtering device used to remove the water from the diesel fuel before it reaches to the sensitive parts of the engine. Water and contaminants have a direct impact on the service life and performance of  diesel engines . Besides being abrasive to engine components and cylinder walls, water and contamination displaces diesel fuel’s lubricative coating on the high precision injector components, causing tolerance erosion, surface pitting, fuel pressure loss and poor performance. Unfortunately, there is no way to completely prevent water from contaminating fuel. Condensation is constantly forming inside fuel tanks. Nowadays, there are number of manufacturers who make fuel water separators with their concept of operation being common and only design variations being the major difference. The first stage of the fuel water separator uses a...
