Routine maintenance of diesel engine fire pump

The fire pump impeller plays a crucial role in the operation and performance of a fire pump. It is a key component responsible for generating the flow and pressure of water or firefighting agents. Here are the main roles and characteristics of the fire pump impeller:

Flow Generation: The primary role of the impeller is to create the flow of water or firefighting agents within the pump. It consists of curved blades or vanes that spin rapidly when driven by the pump’s motor or engine. As the impeller rotates, it draws water into the pump and imparts energy to the fluid, causing it to move radially outward towards the pump outlet.

Pressure Generation: The impeller also contributes to the generation of pressure within the fire pump. The curved blades of the impeller impart centrifugal force to the water, increasing its velocity. This increase in velocity is then converted into pressure as the water is directed towards the pump’s outlet. The shape and design of the impeller blades play a crucial role in optimizing pressure generation.

Efficiency: The impeller design influences the overall efficiency of the fire pump. Efficient impeller designs are aimed at minimizing energy losses and maximizing the conversion of input power into hydraulic energy. Factors such as blade shape, size, and spacing are carefully considered to optimize the impeller’s efficiency and hydraulic performance.

Material Selection: The impeller is typically constructed using materials that are resistant to corrosion, wear, and erosion. Common materials include bronze, stainless steel, or composite materials. The chosen material must withstand the demands of pumping water or firefighting agents, especially when operating in challenging environments.

Impeller Trim: The impeller trim refers to the adjustment or modification of the impeller’s diameter or blade length. By changing the impeller trim, the pump’s performance characteristics, such as flow rate and pressure, can be adjusted to meet specific requirements. Trim modifications are often made during the pump’s installation or commissioning phase to optimize its performance for a given system.

Compatibility and Performance Matching: The impeller is carefully selected to match the pump’s design, performance requirements, and system characteristics. Proper selection ensures that the impeller’s characteristics, such as flow capacity and pressure head, align with the intended application and hydraulic conditions. Matching the impeller to the pump system helps achieve optimal performance and efficiency.

Maintenance and Inspection: The impeller requires regular inspection and maintenance to ensure its proper functioning. Over time, debris or particles may accumulate on the impeller blades, affecting its performance. Regular cleaning, inspection of blade condition, and realignment of impeller components are necessary to maintain optimal pump performance and prevent efficiency losses.

The fire pump impeller is a critical component that contributes to the overall performance and efficiency of a fire pump system. Its role in generating flow and pressure ensures the effective delivery of water or firefighting agents to combat fires and protect lives and property. Proper design, material selection, maintenance, and performance matching are essential to maximize the impeller’s effectiveness and overall fire pump performance.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little influence on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the body is between 85 and 95 °C. If the water temperature is too high, the opening of the ball valve can be increased, the heat dissipation capacity of the heat exchanger can be increased, and the water temperature of the engine cooling water can be reduced. On the contrary, the opening of the ball valve can be closed to increase the water temperature of the engine cooling water.​​
Diesel engine fire pump sets, such as automatic control fire pump sets, add a solenoid valve in parallel with the ball valve in the heat pipe. Under normal circumstances, the solenoid valve is closed, and the cooling water can meet the engine cooling requirements through the gate valve. When the engine cooling water temperature exceeds 95°C, the solenoid valve will automatically open to increase the cooling water flow and reduce the engine cooling water temperature. After 20 seconds, when the water temperature of the diesel engine still exceeds 95°C, the automatic control system will issue an audible and visual alarm and call the staff to the scene to check the cause.

The biggest difference between diesel engine fire pump and electric water pump is that it has its own independent power supply system – battery. Therefore, the start and operation of diesel engine fire pump will not completely depend on city power.

The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.
