Diesel Genset Fire Pump Set to Automatic Control System Requirements

Jan. 11, 2022

Diesel engine cooling system should choose heat exchanger type or radiator type program.  The cooling water circulation system must have an opening for adding refrigerant, checking refrigerant, and replenishing refrigerant as needed.  The refrigerant should meet the requirements of the diesel engine manufacturer.  

 

The cooling circulating water for the heat exchanger shall be sourced from the fire pump outlet in front of the outlet check valve.  The connection shall be a rigid flange connection.  There shall be a manual shutoff valve with indication in the line along the cooling circulating water direction.  When the diesel engine is running, the self-propelled valve shall allow the cooling circulating water to flow to the diesel engine.  The size of the outlet pipe of the heat exchanger shall exceed the size of the inlet pipe.  The outlet line shall be as short as possible and connected to a visible connector, in which no valve shall be assembled.

The radiator shall be designed to ensure that the diesel engine does not exceed its maximum allowable operating temperature when the air inlet temperature at the air filter is 49℃.  The radiator shall include the pipe to the diesel engine and the flange of the exhaust pipe side from which the flexible pipe can connect the fan exhaust pipe side to the exhaust pipe vent/equipment.  

The diesel engine exhaust pipe and exhaust pipe are connected by seamless splicing or electric welding wavy flexible pipe.  Exhaust pipe size should not be lower than the diesel engine exhaust pipe and should be as short as possible.  The exhaust pipe should be wrapped with heat-resistant insulation material.  

Diesel engine hour output power can not be lower than the required operating conditions of the pump shaft power 1.. 1 times;  Diesel engine 1 hour output power can not be lower than the required working conditions of the pump shaft power 1.1 times.

Clutch can not be used in connection between diesel engine and pump.  The diesel engine should be connected with the deep well pump according to the conical bevel reducer and the flexible drive shaft.  The drive shaft should avoid unnecessary stress on the diesel engine or gearbox.  When the solid core shaft is selected and the deep well pump is connected without the use of tapered bevel reducer, the anti-reverse turntable should be included.  

Operation and shutdown requirements of diesel generator set: it should have basic functions of self-operation and manual operation.  Manual operation shall include manual operation beside the diesel engine and on the control cabinet.  It should have excellent operating performance at normal temperature, ensure smooth operation within s, and make the fire pump reach the rated working condition within s after water is added.  Diesel engine fire pump unit can not shut down by itself, only manually operated shutdown, except for overspeed short circuit equipment behavior.  

The overload test should be carried out in 10min. During the test, the pump group should operate normally without abnormal vibration, oil leakage, water leakage and other phenomena.  Operation procedure and warning: there should be operation procedure including emergency operation procedure on diesel fire pump set.  On the diesel engine fire pump set, there should be obvious warning and warning mark on the part of the actual operator's life safety hazard damage.
