1. filling efficiency
1) Filling with single box
The filling is directly carried out from the oil filling port 1, the filling efficiency is 60L/min, the oil tank volume is 50L, the filling time is 50s, two persons are required to carry after filling, and the barrel replacement time is about 30-40s, so that taking the case of filling 16 boxes as an example, the barrel replacement is 15 times, and the total duration is 50 multiplied by 16+15 multiplied by (30-40) =1250-1400 s, and is about 20.8-23.3min. .
2) Centralized filling
Oil is injected from the first through hole 7 at the bottommost layer, the maximum height of the oil is 1m (calculated according to the height of the 4 layers of oil tanks), and the static pressure of the oil port at the bottommost layer can be calculated according to the pressure formula p=ρgh:
P＝ρgh＝820(kg/m 3 )×9.8(m/s 2 ) X 1 (m) =8036 Pa; oiling machine pump-out pressure: 0.2-0.25MPa
The filling pressure is far greater than the oil depth pressure, so that centralized filling can be realized.
The connection time of the 16 empty oil tanks is about 2min, the total filling time is 50×16+2×60=920 s, about 15.3min, and compared with the single tank filling, the concentrated filling time is reduced by 5.5-8min when the 16 oil tanks are filled.
