What is DG checklist?
DG A Check this check is preventive maintainance of DG sets(1000-1500KVA). 1) A-check is done on daily basis here we check: a) oil level b) coolant level c) gauge valve level d) check for any leakage. e) cleanliness of DG set. 2) B-check(done after 300hrs of cycle or 6 months whichever is earlier. )
What is the working principle of DG set?
The functioning principle of a diesel generator is actually based on the law of energy conversion. This law states that the energy can neither be created nor be destroyed but can only be transformed from one form to other. A diesel generator contains an engine that uses diesel for its functioning.
How do you maintain a DG set?
Common Manufacturer Inspections guidelines for diesel generators below,
- Disconnect generator batteries.
- Drain fuel system and change fuel filters.
- Drain coolant and change coolant filters.
- Replace air filters.
- Ensure all intake and exhaust ports are covered.
- Disconnect all generator supply connections.
What is PT pump in DG?
PT Cummins diesel generator fuel pump: low pressure fuel pump, literally P pressure T time. Two of them on the diesel fuel supply control. It provides the maximum supply pressure of fuel injector for 2Mpa. Mainly by the PT fuel pump, PT injector composition.
What are the checks in diesel generator?
engineers and operators can follow this template guide when performing their inspections: perform physical and visual inspection of diesel generator. take photo evidence of leakage, damages, and defects. check the battery, oil and fuel condition. provide overall condition assessment of diesel generator.
Which coolant is used in DG?
1.2 Engine Coolant – Water is the most common coolant used in diesel engines.
How do you calculate diesel per hour?
Simple Method
- Formula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight.
- 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.
- 300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.

How much diesel does a generator use?
Diesel Generator Fuel Consumption Chart
| Generator Size (kW) | 50 Percent Load | 75 Percent Load |
|---|---|---|
| 20 | 0.90 gal/hr | 1.30 gal/hr |
| 30 | 1.80 gal/hr | 2.40 gal/hr |
| 40 | 2.30 gal/hr | 3.20 gal/hr |
| 60 | 2.90 gal/hr | 3.80 gal/hr |
What is the process of maintaining diesel generator?
Preventive maintenance should include a regular general inspection that includes checking the coolant level, oil level, fuel system, and starting system. The charge-air cooler piping and hoses should be inspected regularly for leaks, holes, cracks,dirt and debris that may be blocking the fins or loose connections.
How often should I run my diesel generator?
As a general rule, a generator should be exercised without a load between once a week and once a month. Testing with a load should be done on a monthly or quarterly basis. Your generator’s exercise cycle may be automated by a timer, which ensures the generator is tested on a regular basis.
