How to operate Cummins diesel generator set safely

How to operate diesel generator set safely? Of it is a cliche, there are many users in the use of diesel generating set at present a lot of problems, unit manufacturers after-sales engineers found in reviewing customer diesel generating set, some problems are customers in the process of generating set has no intention of running not standards of operation, actually complete can prevent these problems, diesel generator set in the work, It is necessary to have a special person on duty, and often pay attention to a series of problems that may appear, especially to pay attention to the changes of oil pressure, water temperature, oil temperature, voltage, frequency and other important elements. In addition, we should also pay attention to have enough diesel fuel, in operation, such as fuel infix, objectively formed with load stop, may lead to damage to the generator excitation control system and related components. It is proposed to make rules and regulations and working procedures of the machine room, and check each step and attention every day before starting up, so as to prevent damage to the machine.

One, the preparation before the boot

Check the diesel generator water tank and fuel tank before starting each time to see whether the cooling water or antifreeze in the water tank can meet the startup request, such as short to fill up; Pull out the oil ruler to check whether the smooth oil is short, such as short to add to the regular "static full" scale line. Then carefully check the other related parts for potential problems, found problems to be cleaned in time, all ready to boot. The preparation work before starting is very important. Once the machine is running, these problems are found, which will bring inconvenience to the machine and the work after running.

Two,it is strictly forbidden to start the diesel engine with load

The diesel engine should pay attention to the output air switch of the generator must be in the closed state before starting. After starting the diesel engine of the ordinary generator set, 3-5 minutes of idle operation (about 700 RPM) in winter, low temperature, idle operation time should be appropriately extended for a few minutes. After the diesel engine starts, it is necessary to check whether the oil pressure is normal and whether there is oil leakage, water leakage and other abnormal phenomena, (under normal conditions, the oil pressure must be above 0.2mpa) if abnormal, it should be stopped for maintenance immediately. If there is no abnormal phenomenon, the diesel engine speed is raised to the rated speed of 1500 RPM, and the generator frequency is 50HZ and the voltage is 400V, then the output air switch can be closed and put into use. The generator set is not allowed to operate without load for a long time. If a long time of no-load operation will make the diesel engine nozzle out of the diesel fuel can not be completely extinguished, resulting in carbon accumulation, the formation of valve, piston ring leakage. The other is the automatic generator set, there is no need for idle operation, because the automatic unit is generally equipped with water heaters, so that the diesel engine cylinder has been adhere to about 45 degrees Celsius, the diesel engine can be started in 8-15 seconds of normal power transmission.

Three,pay attention to the running status of the diesel generator

Diesel generator set in the work, time to pay attention to a series of problems may appear, especially to pay attention to oil pressure, water temperature, oil temperature, voltage, frequency and other important elements of the change. In addition, we should also pay attention to have enough diesel fuel, in operation, such as fuel infix, objectively formed load shutdown, may lead to damage to the generator excitation control system and related components.

Four,it is forbidden to stop the machine with load

Before each shutdown, it is necessary to gradually cut off the load, and then turn off the output air switch of the generator set. After that, the diesel engine will be decelerated to idle for about 3-5 minutes and then shut down.

Five, strictly in accordance with the safe operation process stop operation

The safe operation process of diesel generator set is the standard for the operation of diesel generator set in the whole industry, and it is the precious experience of machine operation summarized by many industry technicians, so we can rest assured to operate the machine in accordance with this operation process. The operation procedure meets the article of safe operation procedure of diesel generator set in this site.

The standard operation of the generator set is of great significance to the life of the generator set. In the future, continuous operation will introduce more standard requests for the operation of the generator set.
