Maximum sound pressure level of the pump
Thread Content
If a maximum sound pressure level is required, then what should this maximum sound pressure level be?
For ordinary chemical companies, is it 85dba?
It can be a pump with just one piston, or one that comes with both a pump and a motor. Pumps with 2950 revolutions per minute and a power level of less than 132 kW have a noise level of around 85 dBA; those equipped with motors are likely not able to maintain a noise level of 85 dBA
For a single-finger pump, I’m not sure what the general requirements are
It is usually 85 dBA, but for pumps with a power output of over 132 KW and two poles (with a rotation speed of 2950), it’s difficult to determine this value
Refer to GB/T29529-2013. It is related to the pump’s input power and operating speed.
At 1 meter distance, the overall machine noise (sound pressure) is less than 85 dBA.
