What is the reason for the excessive fuel consumption of 75kw Weichai generator set?

There is more than one reason for the high fuel consumption of diesel generator sets, and users should pay attention to the following checks when they find that the fuel consumption of diesel generator sets used is too fast:

1. When it is found that the oil consumption is too much, you should first check whether there is oil leakage at the connection between the body and the gear chamber cover, the first side of the wheel, the back cover, the cover and other connections. If there is oil leakage, attention should be paid to whether the gasket of each connection part is complete, and the damaged gasket should be replaced for generator leasing. If the gasket is complete, check whether the connecting screws in each part are loose.

For loose bolts, use a wrench to reach the specified torque. If the above parts are basically normal, and the oil leakage is in the frame position, the oil shell should be inspected, the main inspection part is at the front end of the oil shell side on the same side as the running wheel, the generator rental is mostly due to the loosening of the base screws, and the traveling wheel is pulled by the V-belt and the frame angle iron that protects the oil shell for a long time, and the oil shell is worn through to form a gap and produces oil leakage.

2. The normal wear and tear caused by the long-term use of the engine, or the abnormal wear caused by improper maintenance, will cause the cylinder liner of the diesel engine to form longitudinal pull marks, and the cylinder bore and piston side clearance exceed the specified value, so that the supporting force of the piston ring will be reduced accordingly, and the phenomenon of oil scraping will be unclean. Or because the inner support twisting spring in the oil ring is disconnected at the opening position of the oil ring, resulting in the oil scraping is not clean and participates in combustion, resulting in serious oil consumption symptoms, which is manifested as the difficulty of starting the diesel engine, the exhaust pipe has obvious blue smoke coming out, and the respirator is seriously injected. In addition, the piston should be on the upward side, in the assembly due to the direction of the inversion of the combustion chamber to form an inverted state, although it will not affect the start of the diesel engine, but the loss of oil will be quite serious, the daily fuel consumption is about kilograms.

3. Although it is rare for the valve guide to burn the oil of the diesel generator set due to serious wear and tear, it is also a reason that cannot be underestimated according to the introduction of relevant information.

100% (prime) load 217 g kWh, 75% (prime) load 213 g kWh, 50% (prime) load, 214 g kWh, 100% (prime) load fuel consumption.

This is the fuel consumption of your diesel engine, you can compare it.

Weichai 680kw generator no-load fuel consumption per hour is fuel consumption per hour. Weichai WP10 series engine displacement, emission standards China III Euro III, ZUI high output power 247KW, rated speed 2200rpm, full degenerate load ZUI low fuel consumption barrier tracking rate of 196g, this type of diesel engine in full load (rated power) working condition per hour fuel consumption of about 247 196 = 48412 (g), converted to. The no-load fuel consumption of diesel engine per hour is generally about one-fifth of the work, that is, the idle fuel consumption of the diesel engine, the full load fuel consumption of 200 kilowatt diesel generator, usually calculated at 210 grams per kilowatt per hour and 220 grams, the fuel consumption with full load is about 43 kilograms per hour, and the general fuel consumption at idle speed is about 8 10 kilograms.

<> expansion: The fuel consumption of the generator set when it is unloaded is mainly as follows: 1. The work done by the generator to overcome the frictional resistance of the engine and the motor to keep the unit running stably under the empty grinding load.

2. The work done by driving the cooling system (fan water tank). The fuel consumption of the generator set during normal operation is calculated according to the size of the load (power generation), which is related to the energy of the engine (low fuel consumption rate) and the efficiency of the motor. Now Xing can be more advanced engines, Zui low fuel consumption rate is generally 200G, Xing can be a little worse in 240-250G.

For example, the low fuel consumption rate of your 300kw diesel generator set is 200g diesel engine manual), and the fuel consumption for 1 hour at no load is: (overcoming friction work + driving heat dissipation system work) * 200g. The fuel consumption for 1 hour with a load of 200kw is:

200kw * 200g = 40kg, when the load is 300kw dust judgment 1 hour fuel consumption is: 300kw * 200g = 60kg. <>

The hourly fuel consumption of the 800kw generator set is related to the following two factors:

1. Fuel consumption rate, different brands of generator sets have different fuel consumption rates and different fuel consumption;

Second, the size of the electric load, the load is large, the throttle is large, the fuel consumption is larger, on the contrary, the load is smaller, the relative fuel consumption is smaller.

The fuel consumption of the generator is calculated as follows:

One liter of diesel fuel is approximately equal to kilograms (1l = or so.

Most of the generator manufacturers will use g as a parameter, which means how many grams (g) of oil is consumed per kilowatt per hour of the generator set, and then the unit is replaced with liters (l) so that you can know the cost of fuel consumption per hour.

From this, it can be obtained that the fuel consumption of 800kw generator = 168kg = 210L

30kw generator set fuel consumption = kg (kg) = liter (l) 45kw genset fuel consumption = kg (kg) = liter (l).

50kw generator set fuel consumption = kilogram (kg) = liter (l).

75kw generator set fuel consumption = kilogram (kg) = liter (l).

100kw generator set fuel consumption = 21 kg (kg) = liter (l).

150kw generator set fuel consumption = kg (kg) = liter (l).

200kw generator set fuel consumption = 40 kg (kg) = 50 liters (l) 250kw generator set fuel consumption = kg (kg) = liter (l).

300kw generator set fuel consumption = 63 kg (kg) = liter (l).

350kw generator set fuel consumption = kg (kg) = liter (l) 400kw generator set fuel consumption = kg (kg) = liter (l).

450kw generator set fuel consumption = kg (kg) = liter (l).

500kw generator set fuel consumption = kg (kg) = liter (l).

30kw diesel generator set fuel consumption = kg (kg) = liter (l) 45kw diesel genset fuel consumption = kg (kg) = liter (l) 50kw diesel genset fuel consumption = kg (kg) = liter (l) 75kw diesel genset fuel consumption = kg (kg) = liter (l) 100kw diesel genset fuel consumption = 21 kg (kg) = liter (l) 150kw diesel genset fuel consumption = kg (kg) =liter (l) 200kw diesel generator set fuel consumption = 40 kg (kg) = 50 liters (l) 250kw diesel generator set fuel consumption = kg (kg) = liter (l) 300kw diesel generator set fuel consumption = 63 kg (kg) = liter (l) 350kw diesel generator set fuel consumption = kg (kg) = liter (l) 400kw diesel genset fuel consumption = kg (kg) = liter (l) 450kw diesel genset fuel consumption = kg (kg) =liter (l) 500kw diesel generator set fuel consumption = kg (kg) = liter (l) The above is only an estimate and is for reference only.

The specific calculation of fuel consumption of diesel generators is as follows:

One liter of diesel fuel is approximately equal to kilograms (1l = or so.

Most of the parameters used by manufacturers of diesel generators will use g, which means how many grams (g) of oil are consumed per kilowatt per hour of the generator set, and then the unit.

Swap to liters (L) so you know how much fuel you consume per hour.

800kw Cummins generator set fuel consumption calculation can be as follows:

Fuel consumption is calculated according to 200-250g;

Diesel density is calculated according to the accounting;

The fuel consumption of 800kw Cummins generator set is;

The fuel tank has a chassis fuel tank and an external fuel tank, and the general chassis fuel tank capacity can support the generator set to work for 6-8 hours. You can choose 1000L or 2000L for the external fuel tank.

When purchasing 800 kilowatt diesel generator sets, the fuel consumption of the unit is also a matter of great concern to users, and the fuel consumption of diesel generators is affected by many factors, such as:

1. The power of the motor, the production process problems in the assembly process of the diesel engine and the motor, and the rationality of the gear matching also affect the fuel consumption of the generator set.

2. The working environment of the diesel generator set, good ventilation environment, and timely heat dissipation will also reduce the fuel consumption of the generator set.

3. The power of the diesel engine itself, the greater the power, the greater the fuel consumption.

4. Diesel engine manufacturers, due to the production process, technology research and development, application of new technologies, and the material of the internal combustion engine, are also important parts of the fuel consumption of diesel generator sets.

When using the 800 kW diesel generator set, the user should pay attention to the inspection and maintenance of the unit, and deal with abnormal fuel consumption phenomena such as oil leakage of the unit.

100kw diesel generator set fuel consumption = 21 kg (kg) = liter (l).

The specific calculation of fuel consumption of diesel generators is as follows:

One liter of diesel fuel is approximately equal to kilograms (1l = or so.

Most of the manufacturers of diesel generators use G, which means how many grams (g) of oil is consumed per kilowatt per hour of the generator set, and then the unit is replaced with liters (L) so that you can know the cost of fuel consumption per hour.

But in fact, the fuel consumption of 100kw diesel generator set for an hour is affected by many factors, such as the brand of the unit and the actual operation of the unit, so the above data is for reference only, and the actual situation shall prevail.

As a common power supply or emergency backup power supply, the diesel generator set will lose its function if it does not generate electricity, and the reason must be found.

1. Remanence is often lost after shutdown, because the data used in the magnetic pole of the exciter is close to the mild steel, and the remanence is small, and the magnetic field is missing when there is no current in the excitation winding after shutdown.

2. The magnetic pole of the generator loses its magnetism.

3. The excitation circuit components are damaged or the line has an open circuit, short circuit or grounding appearance.

4. Poor contact between the exciter brush and the commutator or the lack of brush holder pressure.

5. The wiring of the excitation winding is wrong, and the polarity is opposite.

6. The contact between the generator brush and the slip ring is poor, or the brush pressure is lacking.

7. The stator winding or rotor winding of the generator is broken.

8. The wiring of the generator lead wire is loose or the switch is poorly touched.

9. The fuse is blown out.

100kw diesel generator set fuel consumption = 21 kg (kg) = liter (l). However, the specific fuel consumption depends on the actual operation of the unit! If there is an oil leak or the fuel consumption is too fast, then this situation cannot be considered.!

Fuel consumption is generally related to two aspects, one is the fuel consumption rate of the unit itself, and the other is the size of the load.
