connection line 2, the smaller oil tank 3 can be taken out in
order to clean and remove water from the smaller oil tank 3.
The oil supplied by Krambs' connection line 2 fills the
small oil tank 3 until the latter overflows. The oil that
overflows from the small oil tank 3 is then collected by
larger
oil-collection tank 1. Supported in the cover 6 of tank 1 is
a float 7 or some other level detection arrangement. The
float 7 has an upper switching position 8 and a lower
switching position 9. When the oil in the tank 1 rises and
float 7 makes contact with the upper switching position 8, an
electrical signal is generated, which is supplied through a
signal box 10 to a control device in a motor 11. This device
switches on a motor 11, which drives a pump 12. By means of a
continuous pumping suction line 13, the pump 12 pumps the oil
out of the tank 1 until the level of oil in the tank lowers
the float 7 to make contact with the lower switching position
9. Consequently, the motor 11 is switched off as a result of
a further signal generated by the lower switching position 9.
