Description
Technical field
This utility model is related to a kind of oil cylinder, and in particular to a kind of to improve system operation used in hydraulic system
The fuel tank of security performance.
Background technology
Hydraulic oil container is used for storing the container for ensureing the fluid needed for hydraulic work system.Master of the fuel tank in hydraulic system
The function is wanted to be：
1. the fluid being stored for needed for system circulation.
2. produced heat when emanation system works.
3. release is mixed in the gas in fluid.
4. the installation for element in system provides position
Wherein, the gas that release is mixed in fluid is particularly important.Reason is to cause air pocket containing bubble in fluid
The generation of phenomenon, what is more bubble is pressurized causes system failure.
The entrance of bubble be fluid by pipeline into point of use when be mixed into air and cause, existing fuel tank finds fluid
It has been mixed into the bubble that is to wait for that big multipotency after air does and has paid fluid rupture naturally.This way is very passive, it is impossible to clear in time
Bubble in degreasing fluid, causes schedule delays.Also have and fuel tank is divided into 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 causes fuel tank volume to become big, standby fluid
Increase, cost is improved.
The content of the invention
The purpose of this utility model is to provide a kind of hydraulic pressure that ensure that into the fluid not bubbles of workpiece
Fuel tank.
To achieve these goals, this utility model includes, a kind of hydraulic oil container, including a casing, sets in the casing
There are a flowline and an oil inlet pipe, flowline and oil inlet pipe are connected with oil cylinder by reversal valve, set on the flowline
The bottom for having oil pump, the casing is provided with air vent, it is characterised in that also including a spill box, and the oil inlet pipe insertion should
In spill box, the top of the spill box is fixed with an annular seal cup, and the lengthwise position of the excircle of seal cup is higher than case
Liquid level when fluid amount is maximum in body, the bottom surface of the spill box is provided with exhaust apparatus, and the exhaust apparatus is sieved by hard
Net and the ventilated membrane adhered on hard screen cloth outer surface are made, and the bottom of the exhaust apparatus connects with the sealing bottom surface of spill box
Connect, and the bottom of exhaust apparatus connects with a fumer, the vacuum pump that the fumer is located at outside casing with is connected.
Spill box makes the fluid of bubbles 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 the low gas content amount in work fluid.The exhaust apparatus being arranged at simultaneously on overflow cylinder bottom surface, by
In the effect of ventilated membrane, fluid cannot pass through, but bubble is under the effect of ventilated membrane opposite side negative pressure-pumping, quick to discharge.So as to
So that there is the air bubble content in wild fluid quickly to reduce.
Distance of the bottom of the flowline apart from the bottom surface of casing is not more than ten centimetres.The bottom of flowline generally within
The bottom of casing, contains bubble substantially due to the buoyancy of bubble herein 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, bores the bottom surface that spill box is fixed at bottom
On.Taper can improve leaving area.
Preferably, the upper surface of the seal cup is provided with netted cutting.Netted cutting can make also flow velocity slow down, and increase
Plus bubble and the time of contacting external air, improve the probability of bubbles burst.
Description of the drawings
Fig. 1 is this utility model schematic diagram.
Specific embodiment
This utility model is described in detail below in conjunction with the accompanying drawings.
As illustrated, a kind of hydraulic oil container, including a casing 1, a flowline 2 is provided with the casing 1 and one is entered
Oil pipe 3, flowline 2 and oil inlet pipe 3 are connected by reversal valve 5 with oil cylinder 6, and the flowline 2 is provided with oil pump 25, the case
The bottom of body 1 is provided with air vent 11, and also including a spill box 31, the oil inlet pipe 3 is inserted in the spill box 31, the 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 the spill box 31 is provided with exhaust apparatus 33, the exhaust apparatus 33 by hard screen cloth and
The ventilated membrane adhered on hard screen cloth outer surface is made, and the bottom of the exhaust apparatus 33 connects with the sealing bottom surface of spill box 31
Connect, and the bottom of exhaust apparatus 33 connects with a fumer 36, the vacuum pump 4 that the fumer 36 is located at outside casing 1 with is connected.
Distance of the bottom of the flowline 2 apart from the bottom surface of casing 1 is not more than ten centimetres.Exhaust apparatus 33 is cone, vertex of a cone position
In the underface of oil inlet pipe 3, cone bottom is fixed on the bottom surface of spill box 31.The upper surface of the seal cup 32 is provided with netted quarter
Groove.
Spill box makes the fluid of bubbles 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 the low gas content amount in work fluid.The exhaust apparatus being arranged at simultaneously on overflow cylinder bottom surface, by
In the effect of ventilated membrane, fluid cannot pass through, but bubble is under the effect of ventilated membrane opposite side negative pressure-pumping, quick to discharge.So as to
So that there is the air bubble content in wild fluid quickly to reduce.
