Magnetic drive pump is referred to as magnetic pump. Magnetic pump is a new product that applies the working principle of permanent magnet coupling to centrifugal pump. It is reasonably designed and has the characteristics of full sealing, no leakage and corrosion resistance. Now let's welcome Taicang Shunda magnetic pump, the manufacturer of Taicang magnetic pump, to introduce how the corrosion-resistant magnetic pump can reduce the noise of the pump.
Corrosion resistant magnetic pump is commonly used in industrial production. What is the reason for the large noise when the user selects the type and the device is used? What are the methods to reduce the noise? The noise of the water pump mainly refers to the aerodynamic noise generated during the transportation of gas / liquid, the structural noise caused by the vibration of the motor casing, the noise caused by the vibration of the base, and the noise of the motor. Such noise level peaks are mainly concentrated in the low octave band, in the range of about 100-450 Hz. The sound source is classified as steady-state noise during normal operation of the pump house. Pipeline noise refers to the noise generated when water flows in the pipeline. In addition, the cavitation phenomenon of the pump and the water hammer phenomenon of stopping the pump can also produce instantaneous noise. The noise generated by the water supply pipeline is affected by the flow rate and pressure.
The noise generated by the whole set of equipment in the pump house is mainly mechanical noise. Now, the noise management method based on the acoustic principle is often used to control the transmission of noise, mainly including sound insulation, sound absorption and noise elimination. Sound insulation is the use of sound insulation structure to isolate the sound source from the sound receiving point; Sound absorption is the use of sound-absorbing structures or materials to reduce noise; Silencing is to reduce the amount of noise by using the principles of impedance, resistance and porous dispersion.
The noise control method shall be based on the acoustic principle and make full use of the site environment and conditions. For example:
1. Control the noise generated by machine equipment and equipment parts. The pump base of the new pump house should be heavy to prevent vibration and noise., Moreover, rubber vibration isolation pads shall be provided for vibration isolation, and then the vibration noise shall be reduced; Each water pump unit shall be provided with a separate foundation to prevent resonance. The "soft" connection shall be selected as far as possible on the suction and pressure pipes of the water pump. Regular maintenance shall be carried out. In case of problems such as packing leakage, loose equipment parts, severe wear of equipment parts, mechanical vibration, etc., timely repair shall be carried out to reduce noise.
2. According to the environment of the pump house, the pump house where the sound source is not tightly closed shall be subject to sound insulation treatment. The room where the noise occurs in the pump house shall be subject to sound absorption / sound insulation treatment, and the doors and windows shall also be subject to sound insulation treatment.
Since different manufacturers and types of pumps have different operating principles and structures, it is very important to conduct on-site investigation and analysis of noise sources for the design of noise reduction plan and selection of materials for the pump house.
