Before the diesel engine fire pump set is commissioned, the relevant linkage equipment should be put into operation, the commissioning personnel should be professional engineers who are familiar with the equipment, and should be familiar with the technical data related to the project before commissioning.

 

 

The debugging site of diesel engine fire pump set shall meet the following requirements:

 

1. Sundries should be removed, and irrelevant personnel should leave the site to a safe location

 

2. There should be no flammable materials near the exhaust system, the exhaust port should not be blocked, and there should be no leakage in the fuel system.

 

3. The line inspection of the power supply system and the insulation resistance inspection of each circuit should be carried out

 

4. Manual cranking should be used to confirm that the diesel engine and the water pump rotate normally, and there should be no corrosion, jamming, or collision. The shaft alignment of the diesel engine and the water pump should comply with the provisions of the technical documents provided with the equipment.

 

5. The inlet valve of the diesel engine fire pump group should be in a fully open state; the outlet maintenance valve should be in a fully open state

 

6. The starting system of the diesel engine fire pump group should be in normal working condition, and the indications of the instruments, indicator lights and alarm devices of the pump group should be correct.

 

 

 

The start-up operation test shall be carried out when the diesel engine fire pump set is commissioned, and shall meet the following requirements:

 

1. When the diesel engine fire pump set is in the form of a centrifugal pump, the diesel engine fire pump set should be started and stopped in closed mode; the diesel engine fire pump set using other types of fire pumps should be started at the minimum power and stopped at the minimum power.

 

2. Continuous operation test should be carried out when the diesel engine fire pump set is debugged. The diesel engine fire pump set will run continuously for 4 hours under rated working conditions without any failure. During operation, the technical parameters of diesel engine speed, lubricating oil pressure, oil temperature, cooling water temperature, exhaust gas temperature, exhaust back pressure, fuel inlet and return resistance, vibration, noise and other technical parameters shall not exceed the limits specified by the diesel engine manufacturer

 

3. After the diesel engine fire pump set is debugged and shut down, the diesel engine fire pump set should be restored to the initial state
