Correct maintenance of diesel engines, especially preventive maintenance, is the easiest and most economical maintenance. Therefore, it is the key to prolonging the service life and reducing the cost of use. First of all, we must do a good job of the daily work of the diesel engine during its use, according to the conditions reflected. , Make necessary adjustments and repairs in time. According to this and refer to the contents of this chapter, different maintenance schedules can be formulated according to the special working conditions and experience of different users.
The content of a daily report generally has the following aspects:.
The date of each shift and the start time, routinely record the readings of all instruments, the use of power, whether the fuel, oil, coolant leak or over-consumption, exhaust smoke and abnormal sound, before and after the failure occurred And processing advice.
First, the main content of maintenance.
Users should carry out regular maintenance according to the technical maintenance items listed in this section. The maintenance levels are as follows:.
Daily maintenance (work per shift).
One-dimensional technical maintenance (cumulative work 100h or every other month).
2D technical maintenance (cumulative work 500h or every 6 months).
Tertiary technical maintenance (cumulative work 1000-1500h or every other year).
Regardless of the type of maintenance, there should be plans, step-by-step inspections and installations, and proper use of tools. The proper force should be applied. The surface of the disassembled parts should be kept clean and coated with anti-rust oil or grease. Prevent rust, pay attention to the relative position of the detachable parts, the structural characteristics of the detachable parts, as well as the assembly clearance and adjustment methods, and keep the diesel engine and accessories clean and intact.
The nameplate on the diesel engine is the effective power, and the Changchun Generator National Standard specifies that according to the use and characteristics of the diesel engine, the nameplate of the diesel engine indicates one or two of the following four types of power.
1,15 minutes Power: Applicable to situations that require short-term good overload and acceleration performance, such as automobiles, motor boats, etc.
2,1 hour power: Suitable for machinery that needs a certain power reserve to overcome sudden load increase, such as wheeled tractors, locomotives, ships and so on.
3, 12 hours power: Suitable for machinery that needs continuous operation within 12 hours and should make full use of diesel engine power, such as agricultural irrigation machinery, locomotives, construction machinery, tractors, etc.
4, Continuous power: Suitable for equipment that needs long-term continuous operation, such as agricultural irrigation and drainage machinery, ships, and power stations.
Therefore, the same diesel engine is used under different power depending on the use and the conditions of use.
(a) Automatic status.
1. Hold the battery of the starting motor up to the starting voltage.
2, keep radiator cooling water level normal, circulating water valve normally open.
3, The crankcase oil level is kept within ±2cm of the dipstick scribing line.
4, the fuel tank is more than half, and the fuel supply valve is normally open.
5. The "Run-Stop-Automatic" switch of the generator control panel is placed in the "Automatic" position.
6, the unit switch mode switch in the "automatic" position.
7, the radiator fan switch hits the "automatic" position.
8. After receiving the signal of loss of mains power, the unit started up, confirmed the loss of mains electricity, cut off the mains switch of the switch cabinet, closed the switch cabinet power switch, and started the air intake and exhaust fan of the engine room and the diesel generator set.
