Abstract
The utility model provides a pneumatic tank fuel supply system, which comprises a fuel tank and an air pump. Communicated with an inlet arranged on the fuel tank, the air pump pressurizes to the fuel tank so as to promote the fuel output of the fuel tank. A flowline is connected to the fuel tank, and a pressure switch electromagnetic valve is disposed on the flowline or the fuel tank. The pressure switch electromagnetic valve and pump control circuit are connected so that the air pump is actuated once the pressure inside the fuel tank is lower than the lower limit value A1. And conversely, pump is shut off once the pressure inside the tank is higher than the highest value A2, A2> A1> 1 atm. According to the arrangement, the pneumatic tank fuel supply system can resolve the problems of being prone to produce negative pressure caused by the use of fuel pump for pumping fuel in the prior art, being unsmooth in oil supply, being difficult in engine starting and operating caused by the high fuel viscosity under the condition of low temperature of the northern winter. Due to the high pressure inside the fuel tank, the transportation of the fuel becomes more smoothly.

The purpose of this utility model is to be achieved through the following technical solutions:
Compressed air type fuel tank oil supply system, comprise fuel tank and air pump, the suction port that arranges on described air pump and the fuel tank is communicated with, by air pump fuel tank is carried out pressurising, and then fuel oil output in the promotion fuel tank, access oil outlet tube in the described fuel tank, on described oil outlet tube or fuel tank be provided with a pressure switch solenoid valve, described pressure switch solenoid valve is connected with the control circuit of air pump, when making the interior pressure of described fuel tank be lower than lower limit A1, air pump starts, when the pressure in the described fuel tank is higher than CLV ceiling limit value A2, air pump cuts out, A2＞A1＞1 barometric pressure.
Preferably, the entrance of described oil outlet tube is near the bottom of described fuel tank.
Also be provided with a pressure-limit valve on the described fuel tank, pressure-limit valve was opened when the pressure in the described pressure-limit valve control fuel tank reached greater than the peak A 3 of A2, in the situation that prevents described pressure switch solenoid valve damage, air pump is worked always, and then causes the excessive problem of tank internal pressure.
Also be provided with oil filler, pressure gauge and Manual air-release valves on the described fuel tank, described pressure gauge is used for the pressure of monitoring fuel tank internal, when refueling, close described pressure switch solenoid valve, open described Manual air-release valves, when pressure gauge shows that tank internal pressure is normal pressure value, open described oil filler and refuel, whether described pressure gauge is used for the pressure that the personnel that drive monitor fuel tank internal constantly simultaneously, normal with the work of understanding whole oil supply system.
Be provided with moisture trap at described air pump with the pipeline that described suction port is connected, the bottom of moisture trap is provided with drain opening, so that the aqueous vapor in the gas is got rid of.
Be provided with one-way valve at described suction port, so that the gas of air pump can only be fed in the described fuel tank, prevent the gas backwash in the fuel tank.
Described suction port, oil filler, pressure gauge, Manual air-release valves all are arranged on the top of described fuel tank.
Further, be provided with sewage draining exit in the bottom of described fuel tank.
Oil supply system through above-mentioned design, can well solve and be easy to produce negative pressure when available engine adopts fuel pump pumping fuel oil, and then cause the obstructed problem of fuel oil feed, and under the low condition of north temperature in winter, the fuel oil stickiness is high, and then causes engine start and running hard problem.Because the existence of fuel tank internal high pressure can make fuel oil more smooth and easy in the feed process.
