Running of diesel generator sets and the use of the plateau area

1.diesel engineMill
New or overhauld diesel engines must be operated through 60 hours before formal use, and can be put into full-load use. Improve the working conditions of the diesel induction, improve the operational reliability and service life of the diesel engine. The engagement of the diesel engine use and the way of dragging, considering the specific mill. In principle, with the increase in the increase of the diesel time, the transfer speed and load in the entire mill are preferably 50% -80%, and the speed should not be more than 80% of the calibration speed of the calibration speed. However, the operation time in the case of the running stage or too small load is not too long. Whenever the cylinder liner, the piston, the piston ring, the connecting rod, and the curved stroke are also appropriately carried out in accordance with the above-described grinding conditions.
2. Normal use of diesel
After the diesel engine is in normal use, you should often watch the indication value of all instruments and the dynamics of the observation of the machine operation; often check the liquid level of the cooling system and the various parts of the lubricant, if it does not match the requirements or if the damage is found, it should Give a supplement or inspection reason. During the operation, especially when the load is suddenly loaded, it should be taken to prevent the failure of the speed to suddenly increase the diesel speed (commonly known as the speed) exceed the specified value, and this situation should quickly take urgent measures, then check Cause.
3. Matching of diesel engine and work mechanical power
When users choose a diesel engine, it should not only consider the size of the power required to support the work machine, but also consider the load rate of the work machine, such as intermittent use, or continuously. At the same time, consider the operational economy of work machine, that is, the load work characteristics and the characteristics of the diesel engine must be reasonably allocated. Therefore, the correct calibration of diesel engine and reasonable matching of diesel engine and working mechanical properties are the premise of ensuring reliable diesel engine, long life, and economic operation, otherwise it will cause diesel overload operation and unnecessary failure; or load power is too small, Diesel power does not have sufficient use, which is not economical and produces disadvantages such as slanting oil.
4. Diesel engine in the plateau area
Diesel Engines are different from the plain regions in the plateau area, bringing some changes to diesel engines in performance and use, and the following descendants are used in the plateau area.

1) Due to the low air pressure in the plateau, the air is thin, the oxygen-containing component is small, and the naturally inhaled diesel engine is deteriorated due to insufficient intake, so that the diesel engine cannot be issued for the original specified calibration power. Even if the diesel engine is the same, the variational power of each type of diesel engine is different, so they are different from the ability of the plateau. For example, the 6135Q-1 diesel engine, the calibration power is 161.8kW / 2200R / min, due to the large calibration power, the overhead is small, the power is 1000m per liter during the plateau, and the power is reduced by about 12%, so The plateau should be appropriately reduced according to the local sea digit height according to the long term of the plateau. The 6135k-11 diesel engine, although the combustion process is the same, but due to only 117.7kW / 2200R / min, the performance has sufficient balance, so that the diesel engine itself has a certain plateau working ability. Taking into account the tendency of the delay in the plateau conditions, in order to improve the operational economy of the diesel engine, the natural suction diesel oil supply advancement should be recommended to advance. Due to the increase in sea, the dynamic decline, the exhaust temperature is rising, so the user should also consider the plateau's plateau working capacity when choosing a diesel engine, and strictly avoid overload operation.
According to the experiment in recent years, the diesel engine used in the plateau area can be used as the power compensation of the plateau. The exhaust gas turbine boost can not only make up for the lack of highlights, but also improved smoke, restore power and reduce fuel consumption rate.

2) As the sea dialect, the ambient temperature is also lower than the plain area, generally 1000m per liter, about 0.6 ° C, the ambient temperature is thin, and the highlights are thinner, so the starting performance of the diesel engine is more than the plain area. difference. When the user is in use, the auxiliary starting measures corresponding to the low temperature start should be taken.
3) Due to the increase in the sea dialect, the boiling point of water is lowered, and the wind pressure and cooling air of the cooling air are reduced, and the heat dissipation conditions per kilowatt in unit time are increased, so the heat dissipation conditions of the cooling system are quapchase. Generally, the high sea-directed area should not be used to use an open cooling cycle, and a pressurized closed cooling system can be used to increase the boiling point of the coolant when used in the plateau.
