Deep well pump how to control the noise

Deep well water pump how to control the noise? Believe that many users do not understand, then follow the small make up to look at this! 1. Control from the aspects of deep well submersible pump design: in order to reduce noise, when the design, to make the number of impeller blades and guide under plate match each other, avoid the resonance, and reasonable control of the impeller and guide vane and diffuser radial clearance, this process a number of factors is bad also can produce noise. Went up from the structure and hydraulic design to reduce noise, this ensures the superiority of congenital control source. 2. Installation and operation to a reasonable: installation should strictly according to the installation program execution, when produce sound source in case. To pay attention to emptying, guarantee allowed on the suction height or necessary NPSH, pump minimum flow control and avoid overload flow operation. 3. Add protective measures: when installed, placed in the bearing parts of the pipe rack antivibration gasket, can also set enclosures around the water pump and motor. Enclosures to sound insulation good material, this method is relatively simple, with fast. 4. No pulsation muffler: double layer cylindrical without pulsation muffler was made abroad, which has two kinds of expansion form and phase entangled form type, as the appearance of this kind of no-pulsation muffler. Will be installed on the device, this kind of no-pulsation muffler received obvious effect. pressure pulse of the frequency of the noise is due to installation without pulsation muffler, the frequency of the noise attenuation almost completely.
