Noise Analysis TaiBang NYP high viscosity pump rotor to generate
NYP high viscosity fluid delivery pump rotor system, a common cause of flow rate, rapid changes in flow and pressure , rupture and alternating load bubbles are noise , high-viscosity fluid delivery pump high viscosity induced system noise The main sources.
Reasonably determine NYP high viscosity pump operating speed of the rotor , the rotating shaft of the gear meshing avoid the resonance frequency can be increased to prevent noise . Because when engaging prone resonance frequency is close to the natural frequency of the gear train . Using appropriate isolation techniques to prevent vibration transmission to adjacent structures . For this reason , the gear pump and drive motor should be connected via a flexible coupling and mounted on the same substrate , in order to ensure concentricity of the resilient support mounted on the base plate can be further improved vibration isolation effect. The pressure on the outlet duct of a high viscosity pump is provided to describe the expansion chamber or accumulator, the pressure pulsation of the pump to absorb or mutation within the buffer line is an effective means to control the high viscosity pump noise.
In general , an open-air work station NYP high viscosity pump rotor maximum allowable noise should be less than 90 decibels of noise sources otherwise deal with active or passive containment , while reducing operating time workers directly exposed to the noise environment. If you really can not control the noise , hearing protection measures should be taken . High viscosity pump during operation if abnormal noise , you should immediately stop check .
