Abstract
The utility model discloses a self-cleaning and overflow preventing fuel oil feeding system for an excavator. The self-cleaning and overflow preventing fuel oil feeding system is characterized in that the self-cleaning and overflow preventing fuel oil feeding system is provided with an oil feeding loop from an oil drum to a fuel tank, wherein the oil feeding loop is sequentially provided with a filter screen switch, a fuel oil filter, a fuel feeding pump and a on-way valve from the oil drum to the fuel tank; the filter screen switch comprises a one-way valve and a preliminary filtering screen arranged between the one-way valve and the oil drum; and the fuel filter consists of a filter element and a bypass valve arranged in parallel to the filter element. According to the self-cleaning and overflow preventing fuel oil feeding system disclosed by the utility model, the fueling operation and fuel cleaning of the excavator can be facilitated; and the waste due to overflow is avoided.
Description
Technical field
The utility model relates to construction machinery and equipment, relates to a kind of fuel oil automatically cleaning of excavating machine, automatic anti-overflow fuel loading system specifically.
Background technology
Existing excavating machine great majority are not configured to fuel tank gas filed fuel loading system, and majority all carries out fuel filling through external device.The part excavating machine refuels through choosing dress fuel loading system.
Existing fuel loading system is made up of fuel charger, transport pipe and ball valve basically, and this form exists following not enough in concrete use:
1, needs the hand switch ball valve in the refueling process, operation inconvenience;
2, the overflow of a part of fuel oil causes waste;
3, the fuel oil of filtered can cause in the fuel charger through fuel charger and stop up, and reduces and refuels efficient and the service life of reducing fuel charger; The fuel oil of filtered gets into fuel tank and causes fuel tank bottom deposit dirt easily.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of excavating machine fuel oil automatically cleaning is provided, from the anti-overflow fuel loading system, with handled easily, clean fuel oil, avoid waste.
The utility model adopts following technical scheme for the technical solution problem:
The utility model excavating machine fuel oil automatically cleaning, be the oil return line that adds that is provided with from oil drum to fuel tank from the constructional feature of anti-overflow fuel loading system, the said oil return line that adds is to set gradually filter screen switch, fuel oil filter, fuel charger and fuel tank check valve until fuel tank from oil drum; Said filter screen switch is to be made up of filter screen check valve and the first filter screen that is arranged between filter screen check valve and the oil drum; Said fuel oil filter is made up of the bypass disc of filter core and parallelly connected setting with filter core.
The utility model excavating machine fuel oil automatically cleaning, also be from the constructional feature of anti-overflow fuel loading system:
Said fuel charger is the single flow fuel charger.
The oil scale that is used to observe fuel liquid level is installed on said fuel tank.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model be excavating machine fuel oil automatically cleaning, from the anti-overflow fuel loading system, can make things convenient for excavating machine refueling operation, clean fuel oil, avoid overflow waste.
2, fuel charger adopts the single flow fuel charger in the utility model, its big flow, big lift; , can under the situation of not opening the excavating machine key switch, refuel directly by the storage battery power supply through wire harness, make refueling process safer.
3, the utility model can utilize oil scale to observe the fluid position in the fuel tank, and is intuitive and reliable.
Description of drawings
Fig. 1 constitutes scheme drawing for the utility model;
The specific embodiment
Referring to Fig. 1; Excavating machine fuel oil automatically cleaning in the present embodiment, be that the oil return line that adds to fuel tank E is set from oil drum F from the anti-overflow fuel loading system, adding oil return line is to set gradually filter screen switch A, fuel oil filter B, fuel charger C and fuel tank check valve D until fuel tank E from oil drum F;
As shown in Figure 1, filter screen switch A be by filter screen check valve A2 and be arranged on filter screen check valve A2 and oil drum F between first filter screen A1 constitute; Fuel oil filter B forms by filter core B2 with the bypass disc B1 of the parallelly connected setting of filter core B2.
In the practical implementation, fuel charger C adopts the single flow fuel charger,, can under the situation of not opening the excavating machine key switch, refuel directly by the storage battery power supply through wire harness, makes refueling process safer.
For the ease of observing, on fuel tank E, install one and be used to observe the oil scale of fuel liquid level.
Present embodiment is by first filter screen A1 the fuel oil among the oil drum F to be carried out filter just; Prevent that bigger particulate matter from stopping up fuel oil filter; Simultaneously; Fuel charger work the time is opened filter screen check valve A2 and fuel tank F is communicated with fuel loading system can refuel, when closing fuel charger, under the effect of check valve spring power, close filter screen check valve A2, prevent the fuel overflow in the fuel loading system under the pressure of fuel oil; Under the normal circumstances, the filter core B2 among the fuel oil filter B is used for fuel oil is further filtered, but when filter core B2 stops up, opens bypass disc B1, makes fuel oil pass through bypass disc B1 and gets among the fuel charger C, can protect fuel charger C like this; Fuel charger work the time is opened fuel tank check valve D and fuel tank E is communicated with fuel loading system can refuel, when closing fuel charger, under the effect of check valve spring power, close fuel tank check valve D, prevent the fuel overflow among the fuel tank E under the pressure of fuel oil.
Excavating machine fuel oil automatically cleaning in the utility model, be in the tool box of excavating machine and trim board, to arrange, do not influence the outward appearance of complete machine from the anti-overflow fuel loading system.
During operation, the source switch that only need open fuel charger C can be realized the automatically cleaning of excavating machine fuel oil, annotate from flowover-proof type.
