Description
Technical field
The present invention relates to a kind of oil cylinder, and in particular to a kind of to improve system operation safety used in hydraulic system
The fuel tank of 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
It is an object of the invention to provide a kind of hydraulic safe that ensure that into the fluid not bubbles of workpiece
Fuel tank.
To achieve these goals, the present invention includes, a kind of hydraulic safe fuel tank, 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 exhaust outlet, 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 vavuum pump that the fumer is located at outside casing with is connected, described fuel-displaced
The bottom of pipe connects with the top of the side elevation of a cylindrical oil-feed tank, and the bottom of the oil-feed tank is provided with two oil-ins, enters
The oil-feed direction of hydraulic fluid port is parallel and does not intersect with the axis of oil-feed tank, and a cylindrical air exhaust is fixed on the bottom surface of the oil-feed tank
Post, the exhaust post is by hard screen drum and adheres to the waterproof ventilated membrane on hard screen drum outer surface and makes, and the exhaust post bottom leads to
Cross pump-line to connect with a vavuum pump outside casing.
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 ward, quick to discharge.So as to
So that there is the air bubble content in wild fluid quickly to reduce.
Meanwhile, fluid is entered from oil-in, because oil-in deviates the axis of oil-feed tank, and exhaust is provided with oil-feed tank
Post so that fluid quickly rotates in oil-feed tank, the little exhaust post of being close to containing alveolate fluid inertia rotates, so as to pass through exhaust
Go out removal of bubbles.Simultaneously the fluid of bubbles is not thrown toward the side-walls of oil-feed tank, the oil that flowline is taken away from side wall top
Liquid is the fluid of not bubbles.Not bubbles in so as to ensure work fluid, improve the stable and security of system operation
Energy.
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.
Preferably, the flowline bottom is divided into two arms.Being divided into two arms and distinguish oil-feed can improve oil-feed tank
The stable shape of interior eddy flow.
