Description

A kind of oil supply system of wide dumper

Technical field:

The utility model relates to mine vehicle technical field, is a kind of oil supply system of wide dumper specifically, is specially adapted to the oil supply system of 6 × 4 wide dumpers.

Background technique:

Mine vehicle generally adopts the diesel oil of the single trade mark, adopts high trade mark diesel oil in the time that temperature is high, adopts the low trade mark diesel oil when temperature is low; But in the time that reality is used, exist significantly not enough: the diesel oil combustion value of the low trade mark is low, and price is high, uses low trade mark diesel oil can significantly increase user cost; If but in the time of low temperature, still used the diesel oil of the high trade mark, because bavin oil viscosity increases, mobility would reduce, and causes vehicle for shortage of oil, more difficult while especially just starting vehicle, even cannot start; The easily wearing and tearing of booster engine in addition; The way generally adopting is at present to work in the time that temperature can use the diesel oil of the high trade mark, and when temperature is reduced to cannot use high trade mark diesel oil can only use lower trade mark diesel oil (as-35#) time with regard to shut-down, vehicle utilization is low.

Also have on part vehicle and install fuel heating system additional at present, in the time of vehicle operating, utilize the diesel oil in electric current or engine cooling water heating fuel tank, can in the time of low temperature, use the diesel oil of high grade; But when cold start-up, cannot heated engine and oil supply system in diesel oil, the mobility of diesel oil is lower, the phenomenon that normal appearance cannot start.

Model utility content:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of quarry tipper oil supply system is provided, and mainly solves wide dumper and cannot use in the time of low temperature the problem of high grade diesel oil.

The technical solution of the utility model is: a kind of oil supply system of wide dumper, and its special way is, is made up of supply system, heating system, three subtense angles of control system; Described supply system is made up of drop tank, the first oil inlet pipe, main fuel tank, motor, the second oil inlet pipe, fuel filter, return tube, described drop tank is connected with motor by the second oil inlet pipe, main fuel tank is connected with motor by the first oil inlet pipe, between motor and main fuel tank, establish return tube, on the oil inlet pipe being connected with motor with the second oil inlet pipe at the first oil inlet pipe, establish fuel filter; Described heating system is made up of fuel heater, intake pipe, return pipe, and described fuel heater is arranged in main fuel tank, is connected by the intake-outlet on intake pipe and return pipe and motor; Described control system is made up of the second solenoid valve, circuit, oil path changing switch, the first solenoid valve, the second described solenoid valve and the first solenoid valve are arranged on respectively on the second oil inlet pipe and the first oil inlet pipe, and the second solenoid valve is connected with oil path changing switch by circuit respectively with the first solenoid valve.

Compared with the prior art the oil supply system of a kind of wide dumper described in the utility model has following good effect: when 1, vehicle normally moves, by the cooling liquid Heating Diesel Fuel of motor, thus can be in the time of low temperature with the diesel oil of the high trade mark; In the time that needs stop, low trade mark diesel oil is full of to whole system, the difficult problem that the vehicle that prevention causes because high trade mark diesel oil condenses in system cannot start; 2, start easily, vehicle utilization ratio is high, reduces costs simultaneously.

Accompanying drawing explanation:

Fig. 1 is schematic diagram of the present utility model.

Drawing explanation:

1 drop tank, 2 first oil inlet pipes, 3 fuel heaters, 4 main fuel tanks, 5 intake pipes, 6 return pipes, 7 motors, 8 second oil inlet pipes, 9 second solenoid valves, 10 circuits, 11 oil path changing switchs, 12 first solenoid valves, 13 fuel filters, 14 return tubes.

Embodiment:

For Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model in detail; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.

Embodiment 1, referring to Fig. 1, by designing requirement, fuel heater 3 is arranged in main fuel tank 4, fuel heater 3 is connected with the intake-outlet on motor 7 by intake pipe 5 and return pipe 6, form heating system, its effect is the diesel oil utilizing in the cooling water of motor 7 heating main fuel tank 4, drop tank 1 is connected with motor 7 by the second oil inlet pipe 8, main fuel tank 4 is connected with motor 7 by the first oil inlet pipe 2, the first oil inlet pipe 2 is connected by fuel heater 3 and main fuel tank 4, on the oil inlet pipe being connected with motor 7 with the second oil inlet pipe 8 at the first oil inlet pipe 2, fuel filter 13 is installed, between motor 7 and main fuel tank 4, install back oil pipe 14, return tube 14 is connected by fuel heater 3 and main fuel tank 4, form supply system, its effect is that diesel oil is supplied to motor from drop tank or main fuel tank, and send unnecessary diesel oil back to main fuel tank, the second solenoid valve 9 and the first solenoid valve 12 are arranged on respectively on the second oil inlet pipe 8 and the first oil inlet pipe 2, the second solenoid valve 9 is connected with oil path changing switch 11 by circuit 10 respectively with the first solenoid valve 12, for ease of handling, oil path changing switch 11 is arranged in operator cabin, form control system, effect is the switch of controlling the first solenoid valve 12 and the second solenoid valve 9 by oil path changing switch 11, thereby switches main fuel tank 4 and drop tank 1 fuel feeding.
