Description
Technical field
The utility model relates to a kind of hydraulic shovel, specifically a kind of large hydraulic digger engine oil-fired system.
Background technique
At present, digger engine oil-fired system on domestic and international market is fuel tank inlet port and out directly connects oil and water seperator by diesel oil pipeline afterwards, then through the filter of diesel oil pipeline Bunker of Redelivery essence, arrive engine oil inlet mouth again, with regard to current alternative oil and water seperator, the filter of fuel oil essence and intermediate fuel pipeline, the requirement of motor producer to oil-fired system resistance and inlet oil temperature can be met.Along with the fast development of China's economic construction, the quality of construct to various infrastructure and speed have had higher requirement, so the demand of large-scale even super sized type hydraulic shovel will rapidly promote.Power system is the heart of hydraulic shovel, the reliability of engine fuel oil system ensures the key factor that engine power exports especially, and the requirement of the oil-feed resistance of large hydraulic fuel oil system of excavator all improves a lot, the engine fuel oil system that current hydraulic shovel adopts can not adapt to the requirement of large hydraulic digger engine oil-fired system.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of engine fuel oil system being applicable to large hydraulic excavator, can effectively reduce fuel oil resistance, improves combustion efficiency, increases engine output.
To achieve these goals, a kind of large hydraulic digger engine of the utility model oil-fired system, comprises fuel tank and engine assembly; Also comprise the first four-way valve block, three oil and water seperator and the second four-way valve block; Described fuel tank oil outlet connects the first four-way valve block through fuel pipe and is divided into three branch roads, article three, branch road connects the filler opening of the oil and water seperator that three are arranged in parallel respectively, it is an oil circuit that three oil and water seperator oil outlets are connected to the second four-way valve block interflow through fuel pipe, and connecting engine assembly filler opening.
The utility model fuel oil is divided into three branch roads through four-way valve block, flow into respectively in three oil and water seperator, then a loop is merged into through another four-way valve block, inflow engine filler opening again, three oil and water seperator adopt and are arranged in parallel and can effectively reduce fuel oil resistance, improve combustion efficiency, increase engine output, the power system of large-scale even super sized type hydraulic shovel can be applicable to.
For preventing oil temperature higher, ensure that motor works under optimum state of temperature.As further improvement of the utility model, described engine assembly oil outlet connects fuel oil radiator through fuel pipe, and fuel oil radiator connects fuel tank filler opening.
As further improvement of the utility model, directly over described first four-way valve block and described second four-way valve block, all have a small ventilating holes.If entrained gas can produce loss to motor in fluid in the process of fuel delivery, therefore offer ventilative osculum at four-way valve block, can by removal of bubbles in fluid.
As further improvement of the utility model, transit joint assembly when described fuel pipe is arranged, is adopted to be separated by fuel pipe.Adopt excessive joint arrangement diesel oil pipeline, can avoid easily bending in the middle of long pipe runs increasing oil-feed resistance, and facilitate diesel oil pipeline care and maintenance.
As further improvement of the utility model, described three oil and water seperator are three townhouse oil and water seperator.Three townhouse oil and water seperator, are just equivalent to nine monomer oil and water seperator and are arranged in parallel, more effectively can reduce fuel oil oil-feed resistance.

In figure: 1, fuel tank, 2, fuel oil radiator, 3, engine assembly, the 4, the 3rd oil and water seperator, the 5, second four-way valve block, 6, transit joint assembly, the 7, second oil and water seperator, the 8, first four-way valve block, the 9, first oil and water seperator.
Embodiment
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, the utility model large hydraulic digger engine oil-fired system, comprises fuel tank 1, engine assembly 3, first four-way valve block 8, three oil and water seperator and the second four-way valve block 5; Fuel tank 1 oil outlet connects the first four-way valve block 8 through fuel pipe and is divided into three branch roads, article three, branch road connects the oil and water seperator be arranged in parallel respectively, namely three branch roads connect the filler opening of the first oil and water seperator 9 respectively, the filler opening of the second oil and water seperator 7 and the filler opening of the 3rd oil and water seperator 4, it is an oil circuit that three oil and water seperator oil outlets are connected to the second four-way valve block 5 interflow through fuel pipe, and connecting engine assembly 3 filler opening.
Fuel flow direction is as shown in arrow points in Fig. 1, fuel oil from fuel tank 1 inlet port out after, three branch roads are divided into through the first four-way valve block 8, then three oil and water seperator be arranged in parallel are entered, an oil circuit is combined into again, last fuel oil inflow engine assembly 3 filler opening by the second four-way valve block 5.
On this external said structure basis, the utility model can also have following improvement project, and connect fuel oil radiator 2 at engine assembly 3 oil outlet through fuel pipe, fuel oil radiator 2 connects fuel tank 1 filler opening.Fuel oil radiator 2 can reduce fuel oil temperature, ensures that motor works under optimum state of temperature.If because in fluid in the process of fuel delivery, entrained gas can produce loss to motor, therefore directly over the first four-way valve block 8 with described second four-way valve block 5, all have a small ventilating holes, can by removal of bubbles in fluid.Adopt transit joint assembly 6 to be separated by fuel pipe when fuel pipe is arranged.Adopt excessive joint arrangement diesel oil pipeline, can avoid easily bending in the middle of long pipe runs increasing oil-feed resistance, and facilitate diesel oil pipeline care and maintenance.Aforesaid three oil and water seperator can be preferably three townhouse oil and water seperator, three townhouse oil and water seperator, are just equivalent to nine monomer oil and water seperator and are arranged in parallel, more effectively can reduce fuel oil oil-feed resistance.
