The entrance point of oil strain inlet valve V1 is being communicated with on-line oil filter 7, and the outlet of on-line oil filter is being communicated with the port of export of oil strain outlet valve V4 by pipeline.
Online oil filtration: can under the situation of not oil extraction of system, carry out the oil strain operation, reduce the oil dissolved gas concentration of component; Can carry out oil extraction, repairing operation by oil-filtering apparatus simultaneously.
Inflation: can fill the fault gas of various proportionings to the oil in the fuel tank, to satisfy test requirements document.
Sampling: sampling when can realize multiposition, plurality of specifications interface, grasp oil, gas quality in the fuel tank in real time.
Vacuumize: before the oil-feed fuel tank is vacuumized, reach self-cleaning function.
