(Yizhong Power Station Diesel Generator Set) How to maintain diesel filter of 300kw Cummins diesel generator set:
The wearing parts of diesel generator set include air filters, oil filters and fuel. the service life of the diesel generator set, it is necessary to strengthen the maintenance of the air filter, oil filter and fuel filter during use.
When installing the diesel generator air filter, seals and rubber connecting pipes should not be missing, installed backwards or installed incorrectly, and sealing of each embedding must be ensured. The air filter in the paper dust container used should be cleaned of dust every 50 to 100 hours of operation. Use a soft brush to remove surface dust. If the operating time exceeds 500 hours or is damaged, it should be replaced promptly.p.s. . Use an oil bath air filter. Every 100-200 hours of operation, clean the filter element with clean diesel and replace the engine oil. If the filter element is broken, it must be replaced immediately. in accordance with regulations during use.
If the oil filter of the diesel generator is not maintained in time during the use of the diesel generator set, the filter element will become clogged, the oil pressure will increase, the safety valve will s will open and the lubricating oil will flow directly into the main oil passage, which will intensify the wear of the lubricating surface, affecting the service life of the diesel generator set. Therefore, the oil filter should be cleaned every 180 to 200 operating hours. If it is found to be damaged, it must be replaced immediately to prevent impurities from penetrating the lubricated surface. When the diesel generator set is used at differentBetween seasons, the crankcase and lubricating surfaces should also be cleaned. The method is to mix engine oil, kerosene and diesel as washing oil. Once the engine oil has been released, the wash oil can be added. for cleaning. Then the diesel generator runs at low speed for 3-5 minutes, then drain all the wash oil and add new engine oil.
The various fuel filters of the diesel generator fuel supply system should be cleared of debris every 100 to 200 hours of operation, and the fuel tank and each oil pipeline should be thoroughly cleaned. Be especially careful when cleaning the filter element and seals. If damage is found, replace it in time. When changing oil during the seasonal transition, all parts of the entire fuel system must be cleaned. THEDiesel used must meet seasonal needs and undergo a 48-hour sedimentation and purification treatment.
Note: Air filter, oil filter and fuel filter are wearing parts when used for more than 500 hours, they should be replaced with new ones. In this way, the service life of the diesel generator set can be better extended.
Cummins generators, as the world's leading generator manufacturer, are known for their excellent quality. So after purchasing a Cummins generator, how to maintain it?
Cummins Generator Engine Maintenance
(1) New engine break-in is an important factor in the maintenance of Cummins generators. When using the Cummins engine for the first time, you should pay attention to the following points: 1. The car should drive at medium and low speeds before starting to avoid high-speed and low-speed driving.heavy load; be idle or run at full speed and full load for more than 5 minutes. 3. Appropriate shift gears to prevent the motor from straining. 4. Always observe the working condition of the oil temperature gauge, oil pressure gauge and water temperature gauge. 5. Check engine oil and coolant levels frequently. 6. Trailers are not allowed and the load capacity is less than 70% of the car's rated load capacity.
(2) When servicing Cummins generator sets, special attention should be paid to starting the engine. 1. Before starting the Cummins generator set for the first time each day, check the coolant level, oil dipstick and drain the oil-water separator. 2. After starting the engine, pay attention to oil pressure changes within 15 seconds. 3. After the prefirst start each day, the machine should be warmed up at medium to low speed for 5 minutes before starting. This should be done when the temperature is below 0°C.
(3) When servicing Cummins generator sets, special attention should be paid to stopping the engine. The engine should idle for 3-5 minutes before stopping, so that the lubricating oil and coolant can carry heat away from the combustion chamber, bearings and friction pairs. This is especially important for supercharged and intercooled engines.
(4) Things to note when servicing Cummins generator engines. 1. Avoid running the engine continuously when the coolant is below 60°C or above 100°C, and the cause should be found as soon as possible. 2. It is prohibited to run the engine when the oil pressure istoo low. 3. The engine must not run for more than 30 seconds at full throttle and maximum torque.
