Troubleshooting: According to common practice, it is generally considered to be caused by air, blockage or loose seal in the diesel generator oil system. However, specifically for this diesel generator, the maintenance personnel first checked the oil system. , filter element and in other related components, no leaks or motor blocking defects were found; fuel pump, fuel injector, etc. were checked and no problems were found in addition, valve clearance, injection advance angle, etc. ; The diesel generator was also checked and adjusted, and the problem was detected. The phenomenon still exists. Finally, after careful observation and analysis by the staff, it was concluded that although the diesel generator stalled automatically, it was easy to start, and the noise and operation were basically normal. The root cause of this type of paIt always resides in the generator oil circuit system, which can be caused by insufficient fuel pre-pressure. Since there is no problem with the oil transfer pump, there is only one reason left for insufficient pre-pressure. -low pressure oil circuit pressure, which is the oil return element. There is a problem with the valve bolts. You can refer to Troubleshooting Daily Engine Failures
Pacific Automotive Network. There are four main reasons: first, no oil; secondly, a blockage of the oil circuit; third, the body temperature is too high; the load is too great. If the machine is not very old or old, replace the spark plug and carburetor. If the machine takes time, the piston rings will need to be replaced.
Gasoline generators are generally composed of stators, rotors, end covers, bearings and other components. The engine is a machine that converts chemical energy into mechanical energy. Its conversion process is actually the work cycle process, it burns the fuel in the cylinder to generate kinetic energy, which drives the piston of the engine cylinder to reciprocate. It drives the connecting rod connected to the piston and the crank connected to the connecting rod to reciprocate in a circular motion around the center of the crankshaft to produce power.
The stator consists of the stator core, wire windings, machine base and other structural parts that secure these parts. The rotor is composed of a rotor core winding, a retaining ring, a center ring, a slip ring, a fan and a rotating shaft. The stator and rotor of the generator are connected and assembled by the bearings and end covers, so that the rotor canit rotates in the stator and performs the cutting movement of the magnetic lines of force, thus generating an induced electric potential, which is evacuated. across the terminals and connected in the circuit to generate current.
Precautions before using the gasoline generator:
1. Check if there is enough gasoline in the fuel tank. ?
2. Check the fuel valve and oil line for oil leaks. ?
3. Check if the oil level is between the upper and lower limits. ?
4. Check the quality of the engine oil to determine if it needs to be replaced. ?
5. Check whether the battery starting voltage is higher than 12V and observe whether the battery appearance is damaged or leaking. ?
6. If the generator is not used for a long time (more than a month), the starter battery will lose power due to self-discharge. An external charger mustbe used to charge the battery.
