mixed-flow pump water pump delivers water flow with large pump strong mobility, suitable for no power supply or movement

The diagram shows a diesel-powered mixed-flow pump. It uses a diesel engine as its power source and transmits power through a belt drive to rotate the mixed-flow pump impeller for operation. The mixed-flow pump combines centrifugal force and axial thrust to transport water, offering a large flow rate and moderate head. This type of pump is highly mobile and is suitable for situations without electricity supply or where mobile operations are required, such as agricultural irrigation and temporary flood relief operations, enabling it to quickly and efficiently complete liquid transportation tasks.1. Power Part

- Diesel engine: The blue-green device at the top of the diagram is the diesel engine, which is the power source of the entire equipment. The diesel engine converts the chemical energy of fuel into mechanical energy by burning diesel. Its operating principle is based on the four-stroke cycle, including the intake, compression, working, and exhaust strokes. At the end of the compression stroke, the injector injects diesel into the cylinder, and the diesel spontaneously ignites at high temperature and high pressure air, pushing the piston to work. The generated power is output through the crankshaft.

- Fuel tank: It is usually integrated above or near the diesel engine, used to store diesel, providing fuel security for the continuous operation of the diesel engine. The fuel tank is generally equipped with an oil level observation device, which is convenient for operators to understand the oil level situation and timely add fuel.

- Air filter: Generally located near the intake of a diesel engine, although it may not be clearly shown in the diagram, it is an important component of the diesel engine. Its function is to filter the air entering the cylinder of the diesel engine, removing dust, impurities, and preventing these particles from entering the cylinder to exacerbate component wear, ensuring the normal and stable operation of the diesel engine.

2. Transmission Part

- Belt Pulley: The red wheel in the diagram is the belt pulley. The power output from the diesel engine is transmitted to the mixed-flow pump through the belt pulley. The belt pulley is connected to the belt pulley of the mixed-flow pump through a belt, utilizing friction to achieve smooth transmission of power. Combinations of different diameter belt pulleys can achieve variable-speed functionality, allowing for adjustment of the speed of the mixed-flow pump to meet actual needs.

- Transmission belt: Connecting the belt wheel of the diesel engine and the mixed flow pump belt wheel, it relies on its own elasticity and friction force to transmit the rotational power of the diesel engine to the mixed flow pump, enabling the mixed flow pump impeller to rotate at the corresponding speed.

3. Part of the mixed-flow pump

- Pump body: The blue shell part shown in the diagram is the pump body, which is the main structural part of the mixed-flow pump. It serves to contain the internal components such as the impeller and guide vanes, and to guide the flow of water in and out. The pump body is generally made of materials such as cast iron or cast steel, which have good strength and corrosion resistance, able to withstand the pressure and erosion of the water flow.

- Impeller: Located within the pump body, it is the key component for the mixed-flow pump to achieve energy conversion. The impeller rotates under the power, applying force to the water flowing into the pump body, making the water flow obtain kinetic energy and pressure energy. The impeller blades of the mixed-flow pump are between those of centrifugal pumps and axial flow pumps, combining the characteristics of both, allowing water to flow with a certain velocity in both radial and axial directions.

- Guide vanes: Some mixed-flow pumps are equipped with guide vanes, which serve to guide the flow of water from the impeller and convert energy. They convert some of the kinetic energy of the water into pressure energy, thereby enhancing the efficiency of the mixed-flow pump. At the same time, they make the water flow more smoothly out of the pump body.

4. Auxiliary Parts

- The chassis and wheels: The black metal frame at the bottom of the device and the wheels constitute the mobile unit. The chassis provides support and a foundation for the entire device, allowing its components to be firmly combined. The wheels give the device mobility, making it convenient to transfer between different work locations, suitable for scenarios such as irrigation in different areas of farmland and drainage at different construction sites.

- Supports and shock absorbers: Although not very apparent in the diagram, in actual equipment, the diesel engine and the mixed-flow pump are typically mounted on the frame via supports and may be equipped with shock absorbers, such as rubber shock mounts. Their purpose is to reduce vibration and noise generated during operation, protecting the equipment's own components from long-term vibration-induced looseness and damage; on the other hand, they reduce the impact on the surrounding environment.
