300KW Diesel Split Case Pumps: Vital for Fire Prevention

The main advantage of the hand-held diesel fire pump is the high lift, which can reach 90 meters. It is generally used for fire emergency fire prevention, forest emergency fire prevention, and factory fire protection. When the diesel engine fire pump is working, the auxiliary impeller is together with the pump main shaft Rotating, the liquid in the auxiliary impeller will also rotate together, and the rotating liquid will generate an outward centrifugal force. On the one hand, this centrifugal force resists the liquid flowing to the mechanical seal, reducing the pressure at the mechanical seal. On the other hand, it prevents the solid particles in the medium from entering the friction pair of the diesel engine fire pump seal, reduces the wear of the mechanical seal grinding block, and prolongs its life. The auxiliary impeller of the diesel engine fire pump can not only play a sealing role, but also reduce the axial force. In the diesel engine fire pump, the axial force is mainly caused by the pressure difference force of the liquid acting on the impeller and the gravity of the entire rotating part. The direction of action of these two forces is the same, and the resultant force is formed by the addition of the two forces.

       The operation of the Fire Pump Set

     Operation of diesel engine fire pump

     Diesel engine fire pump operation:Start, Stop and Run of the Equipment

Start: first make sure of the correct rotatingdirection of the fire fighting pump and the inlet valve is as N.O and outletvalve N.C. Before the pipe network starts with no water. After no error is found, start the fire-fighting pump and, when the pump gets stable run, gradually open the outlet valve and adjust it to the work condition point for the pump to run. The outlet valve is N.O. when the network is filled with water at usual.
Run: when the pump gets a normal run, check the shaft seal and the bearing to see how it works. Theleakage for themechanical seal should not be over 3 drops/min and for the stuffing seal should be dot drop. The bearing’s temperature should not be over 75℃ and its temperature rise not over 35℃ Stop running for a checking case of an abnormal sound during the pump’s run.
To stop, first close the outlet valve, then the diesel engine.

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.

A self-priming pump is able to overcome the problem of air binding by mixing air with water. After it gets rid of the air, the pump will continue to move water like a standard centrifugal pump.It is important to note that self-priming pumps can’t operate without water.Self-priming pumps can handle a variety of fluids and they do well with slurries, corrosive fluids, and solids.Solids handling is one of its most important advantages, as some self-priming pumps can handle solids up to 3 inches.Another advantage, when compared to a submersible pump, is its ability to continue pumping fluid while pump is still situated out of the pit.
