Experience efficient fluid transfer with the XBC-XA Diesel Single stage centrifugal pump. With its unique design and powerful diesel engine, this pump offers reliable performance and exceptional pumping capacity. It is suitable for a wide range of applications, from industrial fluid transfer to fire protection systems.

It can be combined with electric pumps, jockey pumps, etc. to form an automatic water fire protection water supply system, and can be linked with the fire control center.

When the pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set to start the motor to start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine to the rated speed. . The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the pump set receives a signal that the pressure of the pipeline network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.

Whether it’s industrial facilities, commercial buildings, residential complexes, or public infrastructure, Diesel Engine Multistage Fire Pump ensures effective fire protection. With its robust design and advanced features, this pump set is ready to tackle emergencies and safeguard lives and properties in various firefighting scenarios.

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 Diesel Engine End Suction Fire Pump set is suitable for emergency firefighting scenarios, particularly ideal for high-rise water supply, building firefighting, central air conditioning water circulation, industrial process system circulation, cooling systems, boiler water supply, industrial water supply and drainage, water plant supply, irrigation in plantations, and more.

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.

A suction tank provides a stable and continuous water supply to the fire pump. It helps prevent air entrapment and ensures that the pump receives a consistent flow of water during operation.

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in the case of no power supply or abnormal power supply and other emergencies, other diesel engines can also be equipped as power engines according to the needs of users.

As a fixed fire-fighting equipment, the diesel engine fire-fighting pump set has been widely used in fire-fighting diversion, especially for fire-fighting water supply in unexpected situations such as no power supply or abnormal power supply (mains power). The fire pump equipped in the unit is a horizontal single-stage and multi-stage fire-fighting special pump. It is mainly composed of diesel engine, fire pump, connection device, fuel tank, radiator, battery pack, intelligent automatic control panel, etc.

It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. This product can transport clean water or other liquids with physical and chemical properties similar to water.

The number of impellers is different, and the head is also different: Generally speaking, a single-stage pump has only one impeller, while a multi-stage pump has two or more impellers, which enables it to suck water many times and segment it. processing, which greatly increases the lift. Therefore, under the same medium flow, the lift of the multi-stage fire pump appears higher.
