Generally, the fuel cleaning system comprises coarse filtration and smart filter two-stage, and two-stage is separately design separately.Coarse filtration is promptly tentatively filtered fuel oil through oil and water seperator, and smart filter is promptly filtered the fuel oil through preliminary filtration through fine cleaner once more.Usually, oil and water seperator is installed on the vehicle frame and near fuel tank, and fine cleaner is installed in the air inlet side of motor and near the high pressure oil transfer pump of motor.Because motor needs fuel up before work, thereby, can there be air in certain amount in the oil circuit.For the air in the oil circuit is got rid of, be connected with hand oil pump between oil and water seperator and the fine cleaner, fine cleaner is connected with bleed valve.Connect through low pressure fuel pipe between oil and water seperator, hand pump and the fine cleaner.
Yet on the one hand, because the parts of existing fuel cleaning device relatively disperse and the low pressure fuel pipe that connects the two-stage filtering is grown not only but also many, thereby the complex structure of whole fuel cleaning device, occupation space is big and cost is high.On the other hand, when using the hand pump exhaust, on one side need operate hand pump; Observe the relief opening on the fine cleaner on one side; To confirm whether exhaust is accomplished, still, because hand pump in the prior fuel oil filter and fine cleaner be not in the same side of motor; Thereby, when exhaust, be inconvenient to observe the relief opening of bleed valve on the fine cleaner.In addition, there is the drawback that wastes time and energy in the hand oil pump exhaust.
Therefore, be necessary to provide a kind of integrated fuel cleaning device of compact structure to overcome above-mentioned defective.
The model utility content
The purpose of the utility model provides the low integrated fuel cleaning device of a kind of compact structure, exhaust and convenient and cost.
To achieve these goals; The utility model provides fine cleaner that a kind of integrated fuel cleaning device comprises that motor-drive pump, the oil and water seperator that is connected with fuel tank, oil outlet are connected with the high pressure oil transfer pump and the connecting base that is fixed on the engine charge side; Motor-drive pump is fixed on the upper surface of connecting base; Oil and water seperator and fine cleaner are fixed on the lower surface of connecting base; Be provided with a plurality of oil ducts in the connecting base; Between the filler opening of oil and water seperator and the fuel tank, all be communicated with through the oil duct in the connecting base between the oil outlet of the filler opening of fine cleaner and fine cleaner, the filler opening of motor-drive pump is socketed in the oil outlet of oil and water seperator, and the oil outlet of motor-drive pump is connected with the filler opening of fine cleaner.
Preferably, the integrated fuel cleaning device of the utility model also comprises the gear oil pump that is installed on the engine body, and the filler opening of gear oil pump is connected with the oil outlet of motor-drive pump and the filler opening of fine cleaner through oil pipe respectively with oil outlet.
Preferably, the upper surface of connecting base also offers the differential pressure pickup mount inlet, and the differential pressure pickup mount inlet all is communicated with the filler opening and the oil outlet of fine cleaner.
Preferably, the integrated fuel cleaning device of the utility model also comprises the mounting base that a side is fixedly connected with the air inlet side of motor, and connecting base is fixed on the opposite side of mounting base and vertical with mounting base.
Preferably, the integrated fuel cleaning device of the utility model also comprises bleed valve, and bleed valve is fixed on the upper surface of connecting base, and the valve port of bleed valve is communicated with the oil outlet of fine cleaner.
Compared with prior art; On the one hand; Because oil and water seperator, motor-drive pump and fine cleaner in the utility model are all concentrated and be fixed on the same side of the connecting base that is connected with motor, and part is communicated with through the oil duct in the connecting base between oil and water seperator, motor-drive pump and the fine cleaner; Thereby, simplified the integrated fuel cleaning device of the utility model structure, dwindled the assembling that has taken up room, made things convenient for integrated fuel cleaning device of integrated fuel cleaning device and provided cost savings.On the other hand, because the integrated fuel cleaning device of the utility model adopted collection pump oil, exhaust, melted wax and function of increasing pressure is the motor-drive pump of one, thereby, realize automatic vent and guaranteed locomotive cold start-up and proper functioning under rugged environment.In addition, because motor-drive pump is an automatic vent, thereby, made things convenient for the observation of bleed valve relief opening on the fine cleaner.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
