Steyr generator set test machine inspection project
Previous viewing work
We check the unit's label, such as the nameplate, and read the instructions carefully to find out how the unit works, or consult the manufacturer's staff. Check for loose parts in all parts of the unit, do not ignore them because they are new machines; roll the crankshaft to see if there is any abnormal sound in the cylinder.
2. Need to clear the oil seal of the Steyr generator set.
In order to avoid corrosion of the generator set, many manufacturers have to seal the oil before leaving the factory. They need to heat the diesel to about 45-56 degrees so that the rust preventive oil can be removed from the outer chain. If the water is heated above 90 degrees, the local water jacket should be continuously irrigated for 2-3 hours to make the rust preventive oil of each part dissolve better. After the cleaning is finished, you can replace it with new oil and prepare for the start.
3.Start Steyr generator set
Because it is now a new machine, like fuel supply system, lubrication system, starting system, etc. No need to check, if you are not at ease, you can pay attention to the rated parts of the unit at startup to see if there are any abnormalities, so that we can better use the Steyr generator set.
Shutdown with load shutdown or sudden load unloading: After the Steyr generator set is turned off, the cooling water circulation is interrupted, the heat dissipation capacity drops sharply, the heated component loses cooling capacity, and the unit is easily overheated. , causing cracks in the cylinder head, cylinder liner, cylinder block, etc., or the piston is too short and stuck in the cylinder liner. On the other hand, when the Steyr generator set stops idle cooling, the conflicting surface lacks oil. When the machine is started again, wear will increase due to poor lubrication. Therefore, the load should be removed before the generator is turned off, and the speed and load are gradually reduced for a few minutes.
Steyr generator set with load before preheating after cold start: When the generator set starts, due to high oil viscosity, poor fluidity, insufficient oil supply to the oil pump, machine conflict Poor oil lubrication, and even caused problems such as cylinder pulling cylinders and burning tiles. Therefore, the Steyr generator set should be idling after cooling start, and then work with load after the oil temperature reaches 40 °C or higher; the machine should start with a low speed gear and advance a certain distance on each gear in order until the oil temperature Normal, after the oil supply is sufficient, it can become normal operation.
