The end suction pump is a kind of centrifugal pump, which uses the rotation of the impeller to make the water centrifugal move to work. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and water to perform high-speed rotational movement. The centrifugal motion of the water is thrown to the outer edge of the impeller and flows into the pump through the flow path of the volute casing. Pipeline.

The diesel engine pump unit is often used for drainage and municipal flood control in fixed occasions. It is directly driven by the diesel engine. The self-priming diesel engine pump is reasonably configured with a water distribution head. It has the advantages of simple and convenient operation and fast water filling. The unit is equipped with a vacuum auxiliary system, which avoids artificial irrigation and saves time and effort.

Is the fire pump pump shaft break really a product problem? Is the quality not enough, or is the manufacturer cutting corners and using cheap materials?

Fire pump is a water hydrant pump pump, is a higher performance requirements of a pump. Fire pump in the production process and material selection, the requirements are higher than the ordinary water pump.

The new vertical multi-stage fire pump does not have a final guide vane in the water discharge section. After the final impeller is released, the water directly enters the volute-shaped flow passage of the discharge section, and then is discharged from the outlet.

The role of the pump shaft is to support and drive the impeller rotation. The pump shaft shall have sufficient torsional strength, and the deflection shall not exceed the allowable value. The working speed cannot approach the critical speed of resonance. Individual users will encounter the fire pump pump shaft fracture problem. So why did the shaft of the fire pump break?
