4.5.4. Discharge of a sediment from the filter of thin purification of fuel
Hit of moisture in TNVD can put the pump out of action owing to formation of corrosion in it. Formation of water in TNVD is interfered by a settler of the filter of thin purification of fuel. It is necessary to merge a sediment from the filter of thin purification of fuel each 5000 km.
Fig. 4.12. Filter of thin purification of fuel: 1 – the union of removal of fuel to the line of discharge; 2 – the fuel supply union from tanks; 3 – a stopper for production of air; 4 – heater; 5 – laying; 6 – the case of the filtering element; 7 – water discharge stopper; 8 – fuel temperature sensor; 9 – a hose of a supply of the purified fuel to TNVD; 10 – heater socket; 11 – a hose of removal of gate-type fuel from TNVD; 12 – perepuskny valve
For discharge of a sediment from the filter of thin purification of fuel put on a hose the union of the valve of a stopper 7 (see fig. 4.12) a drain opening and turn off a stopper a little. After emergence from a hose of pure fuel wrap the valve and remove a hose.
