Example 2:
Calculation of cleaning time for getting out a certain amount of
cleaning media (prewash).
- The total flow
Q
(m³/h) through the nozzles at the specific pressure used is
taken from the table in “5. Performance Data” on page 9. The total flow in the
tank is then calculated by adding the flow from all machines used at the same
time in the tank.
- Needed amount of washing media
R
(m³) calculated as per Prewash Regulations
or other.
- The time
T
the machine must be in operation is then calculated as:
T = Rx60
Q
(min)
Example 3:
- Prewash rules gives that 6 m³ of cleaning media should be used.
- We have a tank with two (2) machines, each with 2 x Ø 12 mm nozzles, and will
operate the tank cleaning machine at 8 bar pressure.
- How long time should we operate the machine?
Solution
Machine data at page 9 shows that at 8 bar and 2 x Ø 12 mm nozzles will give
a flow of 29 m³/h per machine. Total flow will then be calculated adding both
machines giving a total flow in the tank of 58 m³/h.
Needed time T = 6x60
58
= 6.2 min
