520W a team needs power consumption is much kW.h
If the 520W doesn't have a virtual target, it consumes 0.52 degrees per hour, two hours, 1.04 degrees, and that's about it.
The theoretical calculation is 4.16 kwh, but the hammer can not be 8 hours of continuous work, to hammer the actual working time by 0.52 to get the number of kilowatt hours.
520W a team needs the power consumption, a shift is calculated for 8 hours, 520/1000*8=4.16kw.h. In practice, generally do not work for a hammer shift time, so it can be calculated according to the actual working time; actual working time is calculated as follows: 520/1000*.
Hammer: a safety clutch of electric rotary hammer with a pneumatic hammer drilling mechanism. Hammer is the use of compressed gas piston, impact drill bit, need not make much effort, can open 6--100mm in concrete, brick, stone and other hard materials on the hole hammer in the above-mentioned materials on the opening of high efficiency, but it is not a hole in the metal.
