Inspection steps of diesel generator

Diesel generating set in the purchase of the customer is the most concerned about the generator set price generator set according to the brand is divided into many kinds and different diesel engine power set the unit price is not the same diesel generating unit manufacturers for you to introduce how to compare the price of diesel generator set.
Inquire about the purchase time, use and sale of the old diesel engine, asking what main parts of the previous repairs were changing to ask what problems were in use so as to have a more comprehensive and systematic understanding of the old diesel engine.
Two look at the signs and appearances of the old diesel engine. Look at the time when the factory will produce the factory and how long it will take now to see whether the paint on the exterior is shedding, whether it is defective or not. Judging the old and new degree of the old diesel engine from the sign and appearance.
Three try the test machine. The old diesel engine is carefully inspected by shaking the crankshaft, pulling the flywheel and starting the machine. The test is a very important step. The specific inspection steps are as follows.
1 shake the crankshaft to fuel the nozzle. If the nozzle sends out a crisp sound, it shows that the performance of the nozzle and the piston pair is good, such as the abnormal noise inside the wheel room, which indicates that the gear wear is not serious.
2 up and down the flywheel, if no sound, indicates that the clearance between the spindle stem and the bearing bush is not large.
3 turn the flywheel so that the piston is near the bottom stop and then swaying around. If there is no click, the wear between the connecting rod shaft and the tile is not serious.
4, when the cylinder is reduced and the crankshaft is rotated, when the pressure is removed, the large flywheel of the piston swiftly rotated, indicating that the wear degree of the cylinder, piston and piston ring is small. When rotating the crankshaft, the pointer of the oil pressure gauge should not be less than 1 or the oil mark red mark can rise quickly, and the pressure on the hand should be laborious.
5 start the machine. For example, it is easy to start smoke exhaust, colorless or light grey, stable speed, no noise, indicating that the old diesel engine is in good technical condition.
The installation and testing process of the injection diesel generator set should all operate on the generator controller and track the data of air pressure and oil pressure to monitor the GU631A controller of KAYUN Industrial Company. Therefore, the diesel generator set has high requirements for the controller’s performance, quality stability and humanization of operation. A relatively large number of controllers used in the domestic market for Hongkong Kai Xun Industrial Company’s GU631A controller Market Evaluation of high spraying 150 cubic meters area.
