To achieve the service life of the backup generator during maintenance, if the reliability is not high and the main performance indicators cannot meet the requirements, the safe operation of the data center will be affected and the operation and maintenance cost will be high. Therefore, the data center should be scrapped or replaced resolutely. However, for generators that have exceeded their useful life, their main performance is still good and meet the operational quality requirements, and data center operators can continue to use them on the basis of comprehensive inspection and evaluation. At present, the service life of data center generator set is generally 10 years, and the service of more than 10 years can be called ultra-long service backup generator set.
Frequent engine stops in cold places (a bad habit of some old operating warmers) will result in clean oil and mixing in the cylinder and valve packaging, resulting in serious valve and piston collisions that fail. Cylinder water heater shall be used for heat preservation. For extremely cold areas, moderate viscosity lubricating oil should be selected, equipped with lubricating oil circulation pump, when the unit does not run, lubrication cycle should be carried out, and configured with diethyl ether auxiliary starting device. Unscrew the vent screw on the high pressure oil pump and empty the low pressure oil in the air by hand pump oil; The high-pressure tubing in the air is then drained into the net. The specific method is: the injector tubing joint in the large oil level loosen the throttle, until the crankshaft injector tubing joint oil short circuit.
Currently, a common operational problem in data centers is that generators run empty for long periods of time. The long-term no-load operation of the generator set will lead to the combustion of lubricating oil in the engine and cylinder, and the mixed liquid will be discharged from the exhaust manifold. More serious is carbon deposition in the cylinder, which will accelerate the wear of the cylinder liner.
One of the differences between engine and gasoline engine is compression combustion, so the cylinder should have higher sealing performance. Cold starting engine in cold winter, the piston ring and cylinder wall oil is less, sealing effect is not good, can not repeat the phenomenon of starting. Sometimes because the cylinder wear is too large, it is more difficult to start the cylinder, seriously affecting the sealing performance of the cylinder. For this, the injector can be removed, adding 30~40ml oil in each cylinder, in order to improve the sealing performance of the cylinder, improve the compression pressure. Remove air from oil lines.
Generator data center is the key equipment to ensure the reliability of data center users and power supply. In general, if the generator set size of the subsystem is correct, the appropriate generator set is selected, and the generator is installed correctly, the generator should be able to meet the requirements of the normal operation of the user. Generator maintenance becomes the key after the normal operation of the data center.
The data center of modern generator basically runs from the beginning, in the load reaches the rated frequency and voltage, the important parameter of generator operation state, can monitor from the remote monitoring system, power recovery or shutdown before 5 minutes (set) refrigerator stop, the whole process can be unattended. Therefore, operation, maintenance, training and job training personnel should not be difficult to master the operation of the generator set.
