Energy-saving single-stage centrifugal pumps, multi-stage centrifugal pump energy efficiency requirements

To carry out energy-saving pumps, our country issued on May 13, 2005 by the centrifugal water pump limited value of energy efficiency and energy saving evaluation value 'of the national standard ( GB19762- 2005). On December 1, and in the same year. The standard 5. Article 3 is mandatory, i. e. , water pump the allowable value of energy efficiency and energy conservation value.

'water pump energy efficiency limit value' is defined as: 'the tests specified in the standard conditions, the pump efficiency point minimum allowed value', can be understood as a pump run-time efficiency is lower than the highest efficiency value allows maximum value.

according to the centrifugal pump is classified into three categories:

1) Single-stage single-suction centrifugal pump, the allowable value of energy efficiency - a variety of flow 3%.

       ( 2) Single-stage centrifugal pump, double suction water flow 600 m/h for - or less 3%; - > 600 m/h of flow 4%.

       ( 3) Multistage centrifugal water pump: - 100 m/h or less of flow 3%; - > 100 m/h of flow 4%.

summing up the above, the centrifugal pump of high efficient area allows deviating from the highest efficiency point 3 ~ 4%.

to identify energy-saving pumps, the standard 5. Article 3 also provides the energy value, see the table below, namely 'the tests specified in the standard conditions, the energy saving efficiency of pump regulation point should reach the minimum guarantee of the value of'

choose pump material list should be the minimum efficiency

for procurement to high efficiency and energy saving of high quality water pump, the design personnel equipment materials listed in the table, in addition to the list of Q, H, N, must also indicate the lowest efficiency value, GB19762 - is recommended 2005 provisions are listed on energy value, design selection efficiency value of the pump.

At a time when technology is essential for submersible pump, ensuring that it works in a symbiotic way with your human employees is key.
Knowing these basics of is every essential. But if you don't know how to choose the proper for your specific need, let J&T INDUSTRY CO.,LTD. experts be your guide. Enquire us at J&T INDUSTRY.
