Draw the internal cooling water system of the dual water internal cooling generator

It can be seen that the desalinated water enters the water tank and the cooling water in the water tank is pumped into the chiller by the cooling water pump (one on and one off). day before). Water comes out of the cooler and). is divided into two paths, one leading to the stator and the other to the rotor. The stator winding and the stator winding are cooled, and the water that carries away the heat returns to the water tank and the cycle repeats.

1. Demagnetization of the generator

Cause of failure: The generator has not been used for a long time, causing the residual magnetism contained in the iron core to be lost before leaving. the factory and the excitation coil cannot be installed. At this time, the motor runs normally but cannot produce electricity. This phenomenon is more common in new machines, units stored in humid environments, or units that have not been used for a long time.time. . ?

Treatment method: check the main output circuit of the generator to avoid excitation cannot be established due to short circuit at the output end; if there is an excitation button, press the excitation button; there is no excitation button, use a battery. Magnetize it.

2. Oil leak

Cause of failure: Because there are many places in the engine that use pressure sealing, such as between the cylinder liner, piston and piston ring, compressor overfeeding. rotor shafts, this type of seal usually operates fully when the motor is less than about 1/3 load. A slight leak may occur when the load is low.

Processing method: When using, the low load/no load operating time should be minimized, and the minimum load should not be less than 25% to 30% of the powerunit rating; /p>

3. Insufficient power

Cause of failure: the fuel filter is clogged, resulting in poor fuel supply; the fuel line is leaking and air is entering the fuel inlet pipe; the air filter is clogged, causing poor air intake; the fuel temperature is too high; the engine exhaust pressure is too high, causing crankshaft resistance and loss of engine power; the rear end of the engine compressor and the engine intake manifold, causing insufficient air intake.

Troubleshooting: Check the fuel filter element. If it is clogged or contains a lot of impurities, please replace the fuel filter; If there is a leak, treat it to avoid the engine. air enters the fuel supply pipe during operation; check the air filter element, use compressed air toe clean or replace the filter element, if the fuel temperature exceeds 50°C, please cool the fuel or add fuel to reduce its temperature; check the engine exhaust pipe to make sure the exhaust pipe is clear and the exhaust pressure is less than 90mmHg in cold engine condition or after 5-10 minutes of stopping, check the oil level in oil; pan through the oil dipstick. If the oil level exceeds the "H" position, please drain the excess oil. It is advisable to keep the liquid level between positions "L" and "H" and close to "H". " position; in working condition, use the necessary tools to clean the rear end of the compressor to check the air pipes between the intake manifolds (pay attention to avoid burns caused by high temperature and high gas pressure) and tighten parts with air leaks.
