Abstract
The utility model discloses a refueling system for continuous operation of an excavator, which belongs to engineering machinery refueling systems and is capable of guaranteeing fuel supply for high-load continuous operation. The refueling system comprises a fuel tank, an external refueling assembly (3) is arranged on the fuel tank (1), the fuel tank is communicated with an auxiliary fuel tank through an auxiliary fuel tank refueling assembly (4), and a fuel sucking pipe (8) communicated with an engine is arranged on the auxiliary fuel tank. Since the fuel system capacity is increased, frequencies of halting for refueling can be decreased, and operating efficiency is improved. The refueling system for continuous operation of the excavator is an ideal refueling system suitable for use of engineering machinery requiring high-intensity continuous operation.
Description
Technical field: the utility model relates to a kind of construction machinery and equipment fuel loading system, relates in particular to a kind of excavating machine continuous working fuel loading system.
Background technology: when major natural disasters take place, need the excavating machine operation of in complex environment, uninterruptedly speedily carrying out rescue work for a long time, fuel oil consumption significantly increases.Traditional excavating machine is owing to have only a fuel tank to carry out fuel supply; There is not outer fuel loading system; Therefore must refuel by frequent shutdown, the high-efficient homework ability of excavating machine is not in full use, and can not satisfy the special requirement of needs long-time continuous operation such as rescue and relief work.
Summary of the invention: to the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of excavating machine continuous working fuel loading system that can guarantee high load capacity continuous working fuel supply.
To achieve these goals, the utility model adopts following technical scheme: it comprises fuel tank; Fuel tank is provided with the outer assembly that refuels, and this fuel tank is communicated with the primary fuel case through primary fuel case oiling assembly, and this primary fuel case is provided with the oil suction pipe that is communicated with driving engine.
Fuel tank is provided with the oil return pipe that is communicated with driving engine, and this fuel tank is provided with high position sensor and low sensors, and the primary fuel case is provided with level sensor.
Compare with prior art, the utility model has increased a primary fuel case, thereby has increased the fuel oil system capacity owing to adopted technique scheme on the basis of original fuel tank, therefore can reduce and shut down the gas filed frequency, has improved operating efficiency.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: fuel tank 1 primary fuel case 2 outer assembly 3 primary fuel casees oiling assembly 4 high position sensor 5 low sensors 6 level sensors 7 oil suction pipes 8 oil return pipes 9 that refuel
The specific embodiment: the utility model is described further below in conjunction with accompanying drawing and concrete embodiment:
As shown in Figure 1: fuel tank 1 is provided with the outer assembly 3 that refuels, and this fuel tank is communicated with primary fuel case 2 through primary fuel case oiling assembly 4, and this primary fuel case is provided with the oil suction pipe 8 that is communicated with driving engine.For the ease of understanding the amount of fuel in the fuel tank, be provided with high position sensor 5, be provided with low sensors 6 near the position of bottom near the position at top at fuel tank 1 at this fuel tank, be provided with level sensor 7 at the top of primary fuel case 2.Shut down for fear of primary fuel case 2 et out of orders, on fuel tank 1, be provided with the oil return pipe 9 that is communicated with driving engine.
Principle of work: fuel oil is for 1 the case fuel oil reserve tank, and primary fuel case 2 is an operating oil tank.When the fuel level of primary fuel case 2 was low to moderate level sensor 7 setting values, primary fuel case oiling assembly 4 can be extracted into the oil plant in the fuel tank 1 in the primary fuel case 2 automatically, in time replenishes the fuel oil consumption of driving engine; When the fuel level of fuel tank 1 is low to moderate the position of low sensors 6, alarm equipment alarm, this moment, the available outer assembly 3 that refuels was extracted into the fuel oil in the oil drum in the fuel tank 1; When fuel level arrived the position that high position sensor 5 limits, high position sensor 5 was sent signal, cut off automatically refueling the power supply of assembly 3 outward, and the assembly 3 that refuels outward stops to refuel automatically; Certainly, in refueling process, also can stop oil pumping at any time.
