Diesel is the main fuel for diesel generator sets. The main requirements of diesel generator sets for diesel are good ignitability, good atomization, good low temperature fluidity, less carbon deposition in combustion products, less corrosiveness, and the most important mechanical impurities and less moisture. Therefore, it is necessary to take measures such as precipitation and filtration before the diesel generator set is put into use to remove impurities and moisture, so as to improve the cleanliness of the oil, reduce the wear of parts, prevent the blockage of the oil circuit, and ensure that the oil can play its role. , the following Cummins Engine parts will introduce the purification method of diesel oil for you.
1. Precipitation purification method
Before the diesel fuel is added to the fuel tank of the diesel generator set, according to the principle that the proportion of impurities is larger than that of diesel, the diesel oil is precipitated for a long time by using oil tanks or oil drums, so that most of the impurities will settle to the bottom of the oil drum, usually after 96 hours. The precipitation can remove 0.005mm particles. This method has good effect and is economical and convenient, but it requires sufficient time and oil storage equipment. Generally, the longer the precipitation time, the more obvious the removal effect of small impurities that cannot be removed by the filter. .
2. Do not shake when taking oil
The user must not shake when taking the precipitated diesel oil. The pumping hopper or hose for pumping oil cannot be directly inserted into the bottom of the oil drum, and there should be at least a distance of 80-100 mm from the bottom of the drum. Do not refuel by tilting the oil drum to pour oil. As for the diesel oil below 80-100 mm in the oil drum, they can be collected and used after precipitation and filtration again.
3. Filtration when refueling
When refueling the diesel generator set, the diesel oil must be filtered. This is the last point to prevent mechanical impurities from entering the diesel engine. When refueling with a drawer or self-flow method, it is best to filter it with a fine cloth or other filter material, which can filter the diesel oil. Purification at its best.
The above methods of purifying diesel oil are for your reference. The purification of diesel oil can not only prolong the service life of parts, but also make the generator set work efficiently and improve economy. But here, Hubei JVH would like to remind all users that it is very important to purchase high-quality diesel in order to maximize the performance of diesel generator sets. Users should purchase high-quality diesel that meets the specifications as required, rather than cheap or unqualified diesel. diesel fuel.
