Dear sea friends, regarding the scope of application of \"GB32284-2015 Energy Efficiency Limits and Grades for Petrochemical Centrifugal Pumps\"
Thread Content
Dear sea friends, does the scope of application of \"GB32284-2015 Energy Efficiency Limits and Grades for Petrochemical Centrifugal Pumps\" include magnetic pumps and shielded pumps? If not, are there any specified energy efficiency limits and energy efficiency grades for magnetic pumps and shielded pumps?
The scope of application of GB32284-2015 Energy Efficiency Limits and Grades for Centrifugal Pumps in the Petrochemical Industry does not include magnetic pumps and shielded pumps. At present, there are no specific energy efficiency limits or energy efficiency grade standards for magnetic drive pumps and shielded pumps. .
It is only known that magnetic drive pumps and shielded pumps have low energy efficiency, but the standard \"GB32284-2015 Energy Efficiency Limits and Grades for Centrifugal Pumps in the Petrochemical Industry\" is also rather vague
“This standard specifies the basic requirements for petrochemical centrifugal pumps (hereinafter referred to as “pumps”), the methods for calculating pump efficiency, pump energy efficiency grades, pump energy efficiency limits, target pump energy efficiency limits, and pump energy conservation evaluation values. This standard applies to single-stage single-suction pumps and single-stage double-suction pumps that transport clean liquids and are equipped with closed (maximum) impellers. This standard does not apply to clean water centrifugal pumps, non-metallic centrifugal pumps, and shaftless rotary power pumps. ”Because magnetic drive pumps or shielded pumps also fall under the category of centrifugal pumps
For magnetic drive pumps and shielded pumps, although their energy efficiency may be relatively low, the standard \"GB32284-2015 Energy Efficiency Limits and Grades for Centrifugal Pumps in the Petrochemical Industry\" does not apply to them. This standard is primarily aimed at certain specific types of centrifugal pumps in the petrochemical industry. If information on the energy efficiency of magnetic pumps and shielded pumps is needed, it may be necessary to refer to other more relevant standards or industry guidelines. .
This standard does not apply to clean water centrifugal pumps, non-metallic centrifugal pumps, and shaftless rotary power pumps. Magnetic pumps and shielded pumps both lack shaft seals, so they are not suitable. Currently, there are no specific standards in China for the energy efficiency ratings of magnetic pumps or shielded pumps. However, based on the shaft power of the magnetic pumps we produce, it is possible to use the energy efficiency ratings of centrifugal pumps as a rough estimate. This is Anhui Aochuang Pump Industry Technology Co., Ltd. Wishing you health and happiness every day!
Magnetic pump efficiency is generally low; based on this standard, most of them fall below the specified efficiency limits
Devices that fall below the energy efficiency limits need to be phased out – is this understanding correct?
The standards are clear: shaftless rotary power pumps are not applicable
