Common problems and solutions of diesel engine fire pump sets
XBC diesel fire pump sets may encounter a variety of problems during use, which may involve the start-up, operation, performance and other aspects of the equipment. The following are some common problems and their brief analysis:
1. Unable to start:
The power plug is not firmly connected or the switch has poor contact, resulting in the inability to transmit current normally.
Internal circuit failure of the motor or motor damage may also cause the equipment to fail to start.
2. Insufficient flow:
The head is set too high, resulting in the pump set requiring more power to provide sufficient flow.
Irrational pipeline design, such as too long pipelines and too many right-angle turns, will increase water flow resistance and reduce flow.
Pipe or filter blockage will also reduce water flow.
3. Motor overheating:
The motor runs for a long time or overloads, causing the motor temperature to rise.
There is a short circuit in the wiring or switch, which increases the current and heat when the motor is running.
The impeller or impeller cover is damaged, resulting in poor motor operation and generating additional heat.
4. Unable to suck water:
There is air in the pump body or air accumulation in the water inlet pipe, which affects the normal suction of water.
The check valve is not tight or there is air leakage in the pipe joint, which causes the pump group to be unable to absorb water normally.
5. Early warning failure:
Charging failure causes the battery to be unable to provide stable power support for the equipment.
Low oil pressure may affect the normal operation and performance of the equipment.
Excessive engine cooling water temperature may cause equipment failure or damage.
Engine overspeed or low speed may affect the operating efficiency and safety of the equipment.
Low battery voltage may cause the equipment to fail to start or run normally.
6. Abnormal exhaust color:
Black exhaust indicates imperfect combustion, which may involve problems such as fuel supply and combustion chamber cleanliness.
Blue exhaust indicates that oil has entered the combustion chamber, which may involve problems such as oil leakage and piston ring damage.
White exhaust indicates that diesel oil droplets have failed to ignite and burn in the combustion chamber, which may involve problems such as fuel supply and nozzle failure.
For the above problems, operators should be familiar with the working principle and common faults of the equipment and conduct inspections and repairs in a timely manner. At the same time, regular maintenance and maintenance of equipment are also important measures to ensure the normal operation of equipment and extend its service life.
