Bir dizel jeneratör ne kadar sürebilir sürekli çalışabilir?

Diesel generators are one of the most commonly used backup or main power devices, and are widely used in industrial, reklam, medical, communication, şantiyeler ve diğer yerler. Many users are concerned about a key question when selecting: “Bir dizel jeneratör ne kadar sürebilir sürekli çalışabilir?”

Aslında, the continuous operation time of a diesel jeneratör is affected by many factors, including fuel capacity, load rate, cooling system design and maintenance status.

Factors affecting the continuous operation of diesel generators

6 key factors

Yakıt kapasitesi: determines how long it can run after each refueling. The larger the fuel tank, the longer the continuous operation time.

Load rate (%): Full load operation consumes fuel faster, and partial load can extend the operation time.

Yakıt tüketim oranı (g/kWh) or L/h: affects the fuel consumption per unit time.

Soğutma sistemi: Industrial-grade generators are usually equipped with water cooling systems, which are suitable for long-term high-load operation.

Equipment design: Some high-end models are designed to run for a long time or around the clock

Maintenance level: Regular replacement of filters and oil can reduce the risk of downtime.

Influence of diesel generator load characteristics

What will happen to a 500kW diesel generator set under load?

Parameter table of six different specifications of diesel generators

How long can the six types of diesel generators run continuously?

Detailed analysis of dizel jeneratörler of various specifications

1. Cummins 20kW small generator

Uygulanabilir senaryolar: home backup, small shops or temporary activities.

Running time calculation:
Full load (20KW): 50L fuel tank ÷ 20kW×0.27L/kWh ≈ ​​8-10 hours.

75% load (15KW): 50L ÷ 15kW×0.27 ≈ ​​12-15 hours.

Avantajlar: Silent design (78dBA), suitable for noise-sensitive environments.

Limitations: It is only recommended to run continuously for no more than 24 saat, and long-term high load should be avoided.

2. Hitachi 100kW medium-sized generator

Uygulanabilir senaryolar: hastaneler, hotels or small and medium-sized factories.
​​Running time calculation​​:
Full load (100KW): 200L fuel tank ÷ 100kW×0.25L/kWh ≈ ​​15-18 hours​​.
75% load (75KW): 200L ÷ 75kW×0.25 ≈ ​​20-25 hours​​.
​​Advantages​​: Water cooling system ensures stable operation in high temperature environment.
Not: Turbocharger and coolant level need to be checked every quarter.

​​3. Volvo 500kW industrial-grade generator​​

Applicable scenarios​​: Critical facilities such as data centers and manufacturing plants.
​​Running time calculation​​:
Full load (500KW): 1000L fuel tank ÷ 500kW×0.22L/kWh ≈ ​​24-30 hours​​.
75% load (375KW): 1000L ÷ 375kW×0.22 ≈ ​​35-40 hours​​.
​​Advantages​​: Redundant cooling system supports 72 hours of uninterrupted operation.
​​Maintenance​​: Check the wear of the turbocharger every 200 saat.

4. Perkins 800kW remote site generator​​

Applicable scenarios​​: Mining operations, construction in remote areas.
​​Running time calculation​​:
Full load (800KW): 1500L fuel tank ÷ 800kW×0.2L/kWh ≈ ​​30-35 hours​​.
75% load (600KW): 1500L ÷ 600kW×0.2 ≈ ​​45-50 hours​​.
​​Features​​: Equipped with anti-corrosion coating, suitable for dusty environments.
​​Recommendations​​: Clean the air filter weekly to prevent clogging.

​​5. Caterpillar 1500kW large generator​​

​​Applicable scenarios​​: oil drilling platforms, refineries.
​​Running time calculation​​:
Full load (1500KW): 3000L fuel tank ÷ 1500kW×0.18L/kWh ≈ ​​40-45 hours​​.
75% load (1125KW): 3000L ÷ 1125kW×0.18 ≈ ​​60-70 hours​​.
​​Advantages​​: Double lubricating oil capacity, reduced mechanical wear.
​​Maintenance​​: Check the piston ring sealing every 100 saat.

​​6. Delixi 3000kW power station-level generator​​

Applicable scenarios​​: acil kurtarma, power supply for large-scale events.
​​Running time calculation​​:
Full load (3000KW): 5000L tank ÷ 3000kW×0.15L/kWh ≈ ​​50-60 hours​​.
75% load (2250KW): 5000L ÷ 2250kW×0.15 ≈ ​​75-80 hours​​.
​​Technical highlights​​: Modular design allows for quick replacement of damaged parts.
Not: Replace turbine lubricating oil quarterly to prevent high temperature oxidation.

How long can a 150kw diesel generator set run?

A diesel generator set with a normal power of 150kw, then its operating power for 12 hours is 150kw, and the standby power may reach 180kw. Fakat, if you buy a standby 150kw diesel generator set, then its main power is likely to be only around 120kw. This results in the diesel generator set being small to drag the big, greatly shortening the service life of the diesel generator set, and it is very easy to fail. Genel olarak konuşursak, diesel generator sets should be bought larger rather than smaller. The best power selection is to add about 10% to the actual power consumption.

The best economic operation condition of a diesel generator set is between 75%-90% of the rated power. How long can a 150kw diesel generator set run continuously? If the load power is equal to the 12-hour power of the generator set, then it must be shut down after running continuously for 12 saat. If the load power is 80% of the 12-hour power, it can usually run continuously without time limit. Just pay attention to whether the diesel, yağ, coolant are sufficient, and the temperature. But in actual use, it is best to shut down and rest after 48 saat.
