Generating set remote control system solutions

The generator field loss

The cause of the problem: generating the captain time need not, cause before delivery contains the remanent magnetization in core loss and excitation coil can't afford to build its magnetic field, engine functioning but not sent out the electricity at this moment, this kind of phenomenon in xinji, stored in humid environment or long-term unused units more.

Methods: inspection on generator output circuit, to prevent the output short-circuit excitation cannot be established;Have the magnetization magnetization button button click on the field excitation;Without battery for its excitation button, use the magnetization.

The spill

The cause of the problem: there were more due to the engine in the form of pressure seal, such as cylinder liner - piston, piston ring, turbo - supercharger rotor shaft, this seal in the engine, about one-third of the load to give full play to the role, and load hours will likely slight leakage phenomenon, otherwise may be the following problems:

The piston - cylinder jacket seal is bad, the oil is up, into the combustion chamber combustion, exhaust blue smoke;

For supercharged diesel engine, due to low load and no-load, boost pressure is low.Easy to cause the supercharger drops, oil seal (non-contact) seal oil into the pumping chamber, along with the inlet into the cylinder;

Is up to the part of the cylinder oil burnt, part of the oil can't complete combustion, at the top of the valve, inlet, piston, piston ring, the place such as the formation of coke, and part with the exhaust and together and form a carbon deposit in the exhaust pipe when the accumulation of oil and carbon deposit to a certain extent will flow from the exhaust manifold outlet;

Supercharger turbo indoor oil accumulation to a certain degree, is seeping from the combination of the supercharger surface;

Small load operation for a long time, will lead to the moving parts wear, more serious engine burning overhaul period of early consequences such as environmental degradation.

Methods: should reduce as far as possible when using low load/no-load running time, and the minimum load unit cannot be lower than the rated power of 25% to 30%.

The output power is insufficient

The cause of the problem: the fuel filter clogging caused poor oil supply;Fuel oil pipeline leak, there is air infiltration into the tubing;The engine air filter clogging caused by poor inlet;Fuel oil temperature is too high;Engine exhaust pressure is too high;The oil level of oil is too high, has a resistance leading to engine power loss on the crankshaft;Engine turbocharger between the backend and engine intake manifold may lead to insufficient intake pressure leakage phenomenon;

Check the fuel filter element, such as the clogging or exist a large number of impurities, please replace the fuel filter.Check fuel oil pipeline, such as the leakage situation exists, for processing, to prevent the air into the engine run time for tubing;Check air filter cartridge, use compressed air to clean or replace filter;Measure the fuel temperature, if oil temperature more than 50 ℃, please cool down or the fuel added fuel to reduce the temperature;Check the engine exhaust pipe, to ensure that the exhaust to open, ensure the exhaust pressure is less than 90 MMHG;In cold state machine or downtime for 5-10 minutes, through oil scale check machine oil pan oil surface height, if machine oil surface has more than "H", please get rid of excess oil, liquid level in a "L" and "H" near "H" between a advisable;In running state, with the aid of the tools necessary to turbocharger backend to check between the intake manifold of the trachea (note the check due to high temperature and high pressure gas burns), the existing flat fastening parts;

Oil Pressure insufficient

The cause of the problem: oil crankcase oil level is too low or no oil;Engine coolant temperature is maintained at a higher temperature, lead to the oil caused by oil viscosity is low;Oil pressure sensor or sensor signals might be in short circuit;Oil filter clogging, resulting in shortage of lubricating oil in oil duct;The use of lubricant viscosity level does not accord with the requirement of using the environment;Other fault

Troubleshooting: check the oil the scale of the scale, make sure that the stop after 5 minutes the machine oil surface height between the L and H of the scale close to H to full oil level, if not, please add the same type of oil to the provisions of scale;The processing method, according to a cooling fluid temperature is too high, to ensure that the coolant temperature within a normal range;Check on the pressure sensor wiring to ensure that the connection is firm and reliable, on record press pressure sensor resistance pressure display value, and comparing with the table below, if there is a big difference, please replace the pressure sensor;Replace the oil filter;Check engine oil specification, according to the climate conditions of oil change;If the fault has been ruled out, the engine oil pressure is still low, please contact the generator manufacturer for processing.

The engine coolant temperature is too high

The cause of the problem: an insufficient cooling fluid in the water tank on cooling capacity is insufficient;Crankcase oil too little or no oil;Coolant temperature sensor fault, lead to inaccurate readings or on the high side;Ventilation blocked radiator, cooling air cannot normal circulation led to the decrease of the tank heat capacity;Drive belt loose of cooling fan, fan speed is not caused by the tank heat dissipation ability;Probe is fault engine section, an engine coolant temperature, not normally open large cycle, cause the coolant temperature is too high;Cooling liquid circulating pump problem, which leads to the coolant does not appear high temperature normal cycle.

Fault handling: in the condition of cold machine open the tank cover, check the height of the cooling liquid tank, general with into index can reach the level of shall prevail, if not please add coolant;Check oil scale scale, make sure it down after 5 minutes the machine oil surface height between the L and H of the scale close to the H to full oil level, if not, please add the same type of oil to the provisions of scale;Check the temperature sensor wiring to ensure that the connection is firm and reliable, the measurement of temperature sensor resistance and record the resistance when the temperature of the display value, and comparing with the table below, if there is a big difference, please replace the temperature sensor.Radiator radiator cooling window, if the presence of large amounts of oil or dirt jam the heat-sink window vent, please clean the radiator, ensure the ventilated smooth;Check the wear condition of the radiator fan belt and tensioning degree, according to the need to replace or tension belt;Replace the thermostat;Check the pump impeller, if damaged, should replace the water pump.

Remote fault diagnosis technology
