According to the oil tank, air can be rapidly exhausted,, and running safety of a hydraulic system is ensured.
Description
Technical field
The present invention relates to a kind of oil cylinder is and in particular to one kind can improve system operation safety used in hydraulic system
The fuel tank of performance.
Background technology
Hydraulic oil container is used for storing the container ensureing the fluid needed for hydraulic work system.Master in hydraulic system for the fuel tank
The function is wanted to be：
1. it is stored for the fluid needed for system circulation.
2. produced heat during emanation system work.
3. release is mixed in the gas in fluid.
4. provide position for the installation of element in system
Wherein, the gas that release is mixed in fluid is particularly important.Reason is, can lead to air pocket containing bubble in fluid
The generation of phenomenon, bubble is pressurized what is more leads to system failure.
The entrance of bubble is to be mixed into air when fluid enters point of use by pipeline to cause, and existing fuel tank finds fluid
What after being mixed into air, big multipotency did be to wait for, and bubble pays fluid rupture naturally.This way very passive it is impossible to clear in time
Bubble in degreasing fluid, leads to schedule delays.Also have and fuel tank is divided into multiple units, when the oil of some or certain several units
When liquid has been mixed into air, can be operated using the fluid of other units.This way makes fuel tank volume become big, standby fluid
Increase, cost improves.
Content of the invention
It is an object of the invention to provide a kind of hydraulic oil container that ensure that the fluid not bubbles entering workpiece.
To achieve these goals, the present invention includes, a kind of hydraulic oil container, including a casing, is provided with one in this casing
Individual flowline and an oil inlet pipe, flowline is all connected with oil cylinder by reversal valve with oil inlet pipe, and described flowline is provided with oil
Pump, the bottom of described casing is provided with air vent it is characterised in that also including a spill box, and described oil inlet pipe inserts this overflow
In case, the top of described spill box is fixed with an annular seal cup, and the lengthwise position of the excircle of seal cup is higher than in casing
Liquid level when fluid amount is maximum, the bottom surface of described spill box is provided with exhaust apparatus, this exhaust apparatus by hard screen cloth and
The ventilated membrane adhering on hard screen cloth outer surface is made, and the bottom of this exhaust apparatus is connected with the sealing bottom surface of spill box, and
The bottom of exhaust apparatus is connected with a fumer, and the vacuum pump that this fumer is located at outside casing with connects.
Spill box makes the fluid of bubbles all flow to the upper surface of the fluid in casing, so that bubble cannot be introduced into oil
Inside liquid.Further it is ensured that low gas content amount in work fluid.It is arranged at the exhaust apparatus on overflow cylinder bottom surface simultaneously, by
In the effect of ventilated membrane, fluid cannot pass through, but bubble, under the effect of ventilated membrane opposite side negative pressure-pumping, is quickly discharged.Thus
So that there being the air bubble content in wild fluid quickly to reduce.
The distance apart from the bottom surface of casing for the bottom of described flowline is not more than ten centimetres.The bottom of flowline generally within
The bottom of casing, herein due to the buoyancy of bubble basic containing bubble such that it is able to reduce the pressure at expulsion of oil-feed tank.Enter one
Step ensures not bubbles in flowline.
Preferably, exhaust apparatus is cone, and the vertex of a cone is located at the underface of oil inlet pipe, and the bottom surface of spill box is fixed at cone bottom
On.Taper can improve leaving area.
Preferably, the upper surface of described seal cup is provided with netted cutting.Netted cutting can make also flow velocity slow down, and increases
Aerating bubble and the time of contacting external air, improve the probability of bubbles burst.
Brief description
Fig. 1 is schematic diagram of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in detail.
As illustrated, a kind of hydraulic oil container, including a casing 1, be provided with a flowline 2 in this casing 1 and one enter
Oil pipe 3, flowline 2 is all connected with oil cylinder 6 by reversal valve 5 with oil inlet pipe 3, and described flowline 2 is provided with oil pump 25, described case
The bottom of body 1 is provided with air vent 11, also includes a spill box 31, and described oil inlet pipe 3 inserts in this spill box 31, described overflow
The top of case 31 is fixed with an annular seal cup 32, and the lengthwise position of the excircle of seal cup 32 is higher than fluid amount in casing 1
Liquid level when maximum, the bottom surface of described spill box 31 is provided with exhaust apparatus 33, this exhaust apparatus 33 by hard screen cloth and
The ventilated membrane adhering on hard screen cloth outer surface is made, and the bottom of this exhaust apparatus 33 is connected with the sealing bottom surface of spill box 31
Connect, and the bottom of exhaust apparatus 33 is connected with a fumer 36, the vacuum pump 4 that this fumer 36 is located at outside casing 1 with connects.
The distance of the bottom surface apart from casing 1 for the bottom of described flowline 2 is not more than ten centimetres.Exhaust apparatus 33 is cone, vertex of a cone position
In the underface of oil inlet pipe 3, bore bottom and be fixed on the bottom surface of spill box 31.The upper surface of described seal cup 32 is provided with netted quarter
Groove.
Spill box makes the fluid of bubbles all flow to the upper surface of the fluid in casing, so that bubble cannot be introduced into oil
Inside liquid.Further it is ensured that low gas content amount in work fluid.It is arranged at the exhaust apparatus on overflow cylinder bottom surface simultaneously, by
In the effect of ventilated membrane, fluid cannot pass through, but bubble, under the effect of ventilated membrane opposite side negative pressure-pumping, is quickly discharged.Thus
So that there being the air bubble content in wild fluid quickly to reduce.
