First, the maintenance of centrifugal lubricant filter
1. After every 250 hours of operation of the lubricant filter, the dirt on the inner wall of the rotor should be cleaned. When cleaning, the fixing nut on the upper part of the housing should be removed, then the nut on the upper end of the rotor is removed, the rotor is taken out, and then the rotor body and the rotor seat are disassembled and placed in clean diesel oil for cleaning.
2. The speed of the centrifugal lubricant filter rotor is an important indicator to assess its filtration efficiency. When the diesel engine is running at a rated speed, the rotation speed of the rotor is generally 5500-6500 r/min. When the rotation speed of the rotor is lower than 5000r/min, the filtration effect of the centrifugal filter is significantly reduced; if the rotation speed of the rotor is lower than 2000r/min, the filter will lose the filtering ability.
3. Detection method of rotor rotation speed: After the diesel engine is started, it is adjusted to the rated rotation speed. When the temperature of the lubricating oil is above 60 CC, the diesel engine is stopped. At this moment, the rotor will continue to rotate due to inertia and issue a crisp and continuous “嗡.å—¡ å—¡ å“ å“ å“ å“ å“ å“ å“ å“ å“ å“ å£°éŸ³ 。 。 。 。 。. Under normal circumstances, this sound lasts for about 40 seconds. The rotor cover can also be removed for inspection. If there is no deposit in the rotor cavity and the coarse filter element and lubricant are dirty, this means that the rotation speed of the rotor is too low to meet the specified requirements.
Second, winding lubrication oil filter maintenance method
Winding lubricant filter easy to use in the damage: metal belt loose, open welding and filter plugging. When the filter element is damaged, open or metal tape is loose, it can be cleaned with gasoline and dried, and then soldered for soldering. Under normal conditions, the area of ​​the weld plug should not exceed 10% of the total area of ​​the filter core.
3, the maintenance method between the side and the pressure limit: Bypass valve and pressure limiting valve under normal circumstances do not have to dismantle and repair, but if the ball valve and seat inside the bypass valve has serious wear, limited elastic spring weakened or broken , should be disassembled for inspection. When the ball valve and the valve seat are worn lightly, a grinding noise can be applied between the ball valve and the valve seat for grinding. When the abrasion is serious, the seat surface can be mirrored or ground, and then the valve surface can be replaced or ground. Ball valves can be replaced with steel balls of the same diameter.
The above is the maintenance method of the diesel generator set oil filter introduced by Hua Quan Power. Hopefully the above introduction can help the user.
