Top is equipped with respirator 13, is equipped with the partition 16 for being divided into oil back chamber and oil sucting cavity, the upper and lower side of partition 16 in cabinet 11
Have notch；The bottom plate of cabinet 11 is equipped with the inlet port B of connection oil sucting cavity, and inlet port B is fuel-displaced with oil-suction oil filter 15
Mouth connection, oil back chamber are interior by being fixedly connected with return oil filter 12 at the top of flange and cabinet 11；Return oil filter 12 has perpendicular
Vertical oil return filter cylinder 12-1, the bottom of oil return filter cylinder 12-1 are welded with fuel-displaced steel pipe 12-3 straight down, are welded on side wall
Two oil returning steel pipe 12-5 outside cabinet 11 are stretched out, the outer end of oil returning steel pipe 12-5 is welded with oil return flange 12-4, oil return method
Blue 12-4 is equipped with oil return opening A；The inner end of oil returning steel pipe 12-5 is equipped with oil return baffle 12-2, as shown in Figure 6.This excavator liquid
Pressure oil case has the disadvantage that oil liquid flows out impact tank bottoms from fuel-displaced steel pipe in use, can make to generate in fuel tank
A large amount of bubble；Oil liquid flows into oil return filter cylinder from oil returning steel pipe impacts oil return baffle, can also make to generate a large amount of gas in fuel tank
Bubble；Bubble can enter oil sucting cavity from the notch of partition lower end with hot oil, and a large amount of bubble also can be inhaled into hydraulic pressure system with oil liquid
In system, causes hydraulic system to generate noise, vibration, air pockets erosion etc., cause the working efficiency of Hydraulic Elements low.Oil liquid is in oil
It cannot get abundant circulating cooling in case, a large amount of hot oils are directly pumped from inlet port into hydraulic system, accelerate hydraulic pressure system
The rising for oil temperature of uniting, energy consumption increase, and can also accelerate the aging of oil liquid.
Summary of the invention
The problem to be solved by the invention is to provide a kind of excavators to drop bubble hydraulic oil container, it can solve existing excavator
When the oil liquid of hydraulic oil container flows into fuel tank from return oil filter, it can make to generate a large amount of bubble in fuel tank, bubble can be with oil liquid quilt
It is drawn into hydraulic system, causes the working efficiency of Hydraulic Elements low and oil liquid is in fuel tank cannot get abundant circulating cooling
The problem of.
To solve the above-mentioned problems, the technical solution adopted by the present invention is that: this excavator drop bubble hydraulic oil container includes
Cabinet, the cabinet is interior to be equipped with the partition for being divided into oil back chamber and oil sucting cavity, and the upper end of the partition is provided with notch, described
The bottom plate of cabinet is equipped with the inlet port for being connected to the oil sucting cavity, and the oil outlet connection of the inlet port and oil-suction oil filter is described
The bottom plate of cabinet is equipped with the oil return opening for being connected to the oil back chamber, and the oil inlet connection of the oil return opening and return oil filter is described
Return oil filter is installed in the oil back chamber, and oil liquid flows into the oil back chamber by the return oil filter from inside to outside.
In above-mentioned excavator drop bubble hydraulic oil container technical solution, more specific technical solution may also is that the oil return filter
The oil inlet of oily device is connect with the oil return opening by oil revolute chamber, and the oil revolute chamber has the shell connecting with the return oil filter
The lower end of body, the shell is equipped with multiple oil nozzles by connecting plate, and the connecting plate is equipped with oilhole corresponding with the oil nozzle.
Further, to the oil suction cavity dumping, inclined angle alpha is 15~20 ° on the top of the partition.
Further, gap is equipped between the partition lower end and the bottom plate of the cabinet.
Further, the notch area of the partition upper end is greater than the area of the inlet port.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
1, the present invention enters oil liquid in return oil filter from oil return opening, and the oil liquid in return oil filter flows from bottom to top, so
Flow into the oil back chamber of cabinet from inside to outside afterwards, oil liquid enters oil sucting cavity by the notch of partition upper end, inhales from inlet port by pump
Enter into hydraulic system.This circuit oil liquid will not impact tank bottoms, avoid generating a large amount of bubble in fuel tank, simultaneously
Increase the circulation time of oil liquid in fuel tank, bubble can emersion liquid level, improve bubble separation efficiency, hydraulic oil container can be eliminated
In most of bubble, prevent bubble to be inhaled into hydraulic system with oil liquid, avoid hydraulic system generate noise, vibration,
Air pockets erosion etc., improves the working efficiency of Hydraulic Elements.Since the circulation time of oil liquid in fuel tank increases, oil liquid can be obtained
To circulating cooling, hot oil is avoided to be pumped in hydraulic system, prevents oil temperature in hydraulic system from rising too fast, energy consumption drop
It is low, delay the aging of oil liquid.Oil return opening, inlet port are all located on the bottom plate of cabinet, be can also be used as the Butterworth Hatch of fuel tank, are convenient for
Oil tank cleaning is clean.
2, the oil inlet of return oil filter is connect with oil return opening by oil revolute chamber；Extend oil liquid in fuel tank by oil revolute chamber
Circulation time further enables bubble emersion liquid level, and oil liquid can obtain sufficient circulating cooling, and the structure is simple, manufacture at
This is low.
3, to oil suction cavity dumping, inclined angle alpha is 15~20 ° on the top of partition；Bubble can be guided to float along partition
To liquid level, the efficiency of bubble rising is greatly promoted, reduces the air bubble content for entering oil sucting cavity.The reduction of air bubble content can contract
Small volume of fuel tank realizes the hydraulic oil container of miniaturization.
4, gap is equipped between the lower end of partition and the bottom plate of cabinet, convenient for removing fuel tank siltation and maintenance.
5, the notch area of partition upper end is greater than the area of inlet port, and control enters the oil liquid flow of oil sucting cavity, makes to enter
The oil liquid flow of oil sucting cavity meets the needs of hydraulic system, while extending oil liquid in fuel tank more than the flow of sucking hydraulic system
Circulation time.
