DG multi-stage boiler feed pump suitable for conveying the temperature below 110 ° C water or physical and chemical properties similar to the water-free non-corrosive other liquids, widely used in industrial and mining enterprises and the boiler water supply and urban life water supply. DG-type multi-stage pump is particularly suitable for boiler feed water, can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, farmland irrigation , fire pressurization, hydraulic washing, food, brewing, medicine, chemicals, aquaculture, Environmental protection and other industries. For the safety of the operator, DG-type horizontal multi-stage boiler feed pump start operation, it should be noted that the boiler feed pump start operation precautions;       1, DG horizontal multi-stage boiler feed pump operation Note:         1) Before starting the pump, rotate the rotor and check whether the rotor is flexib...

Boiler pump noise is a reflection of the characteristics of the working state of the pump, the Boiler pump noise, mainly by the various parts of the pump parts or pump flow of media generated. Reduce the noise, it is necessary to carefully analyze the noise generated by the sound source to improve the structure of the sound source or medium motion. 1, the main causes of noise in the following areas:         1) mechanical noise         Multi-stage centrifugal pump with the guide vane, rigid or guide the population at the cross-sectional area and the entrance edge thickness with unreasonable, it may cause a larger vibration generated by the pump noise.         Second, the pump rotor parts and non-rotating between the pump, due to contact friction, will also produce higher frequency noise.         Due to the external structure of the boiler feed water pump and the installation of the problems arising fro...
