Installation case:
Seven 7.5KW CNC machine tools for processing LED lampshades in a hardware processing factory in Zhongshan City have been equipped with PGC machine tool specific energy feedback devices, saving the factory 40880 degrees of electricity.
The test results of a single unit running for 168 hours are as follows:
1) Node table degree display: 112 degrees
2) Electricity consumption meter reading: 340 degrees
3) Total power consumption=Node meter degree+Power consumption meter degree=452 degrees
4) Power saving rate=112/452=24.78%
2. Annual comprehensive energy-saving calculation: a single machine tool can save 16 kWh of electricity per day, and 7 machine tools can save 40880 kWh of electricity per year
