Description
Technical field
The present invention relates to the hydraulic system of a kind of automatic cooling, be specifically related to a kind of automatic cooling and avoid the hydraulic pressure system of heating
System.
Background technology
Britain Joseph Bu Laman in 1795, uses water as working media in London, is answered with the form of hydraulic press
For industrial, be born First hydraulic press in the world.Within 1905, change working medium water into oil, further changed
Kind.After the World War I, hydraulic drive is extensively applied, and particularly after nineteen twenty, develops the rapidest.Hydraulic Elements are big
About between 20 years of 19 beginnings of the century in the end of the century 20, just initially enter the regular commercial production stage.Nineteen twenty-five Vicks VapoRub is invented
Pressure balance type vane pump, or hydraulicdriven progressively set up industrial for Hydraulic Elements in modern age is laid a good foundation.20 beginning of the century health
The theory and practical study carried out is transmitted in energy hunting by Si Tanding Nice gram；1910 to the tribute in terms of hydraulic power
Offer, make these two aspects field be developed.During World War II, have 30% to apply hydraulic pressure in US Machine Tools and pass
Dynamic.It it is noted that nearly more than 20 years of the Japanese hydraulicdriven development country such as more American-European evening.Before and after nineteen fifty-five, Japan is rapidly
Development hydraulic drive, has set up " hydraulic industry meeting " in 1956.Between nearly 20 ~ 30 years, Japan's hydraulic drive development is fast, occupies the world
Leading position.Hydraulic system is controlled by signal and hydraulic power two parts form, and signal control portion is used for driving hydraulic power
Control valve action in part.Hydraulic power part uses loop diagram mode to represent, to show the phase between difference in functionality element
Mutual relation.Hydraulic power source contains hydraulic pump, motor and hydraulic pressure auxiliary element；Hydraulic control portion contains various control valve, and it is used
In controlling the flow of work fluid, pressure and direction；Executable portion contains hydraulic cylinder or hydraulic motor, and it can be by actual requirement
Select.
But can generate heat in oil pipe during conventional hydraulic long-term work, the accumulation effect of generation can cavitate, damage
Pump head or pipeline, the most effective problem hydraulic system cooled into a research of having to.
Summary of the invention
The technical problem to be solved is to cool hydraulic system, it is therefore intended that provide a kind of cooling automatically
Avoid the hydraulic system of heating, the problem solving hydraulic system is cooled.
The present invention is achieved through the following technical solutions:
The hydraulic system of heating is avoided in a kind of automatic cooling, including main hydraulic cylinder, separatory cylinder pressure oil pipe, fuel tank and separatory cylinder pressure
Internal pump head, connects and arranges multidirectional flow divider on the oil pipe of two hydraulic cylinders, connects and sets on the oil pipe of main hydraulic cylinder and fuel tank
Put oil sucting one-way valve, connect and on the oil pipe of separatory cylinder pressure and fuel tank, stop valve is set, the oil pipe connecting two hydraulic cylinders sets
It is empty chamber and air-permeable layer, fuel tank arranges passage；Described cavity is that one end that outward expansion is formed centered by oil pipe is closed
The unification cavity opened of end and the one end opened and air-permeable layer connect, and cavity is arranged on hydraulic oil and hoists transmission from lower
Position；Described air-permeable layer is in cylindrical sleeve outside oil pipe, and one end is opened the other end and is connected with cavity, and air-permeable layer is internal and oily
Tube-surface forms cavity layer and air-permeable layer surface is provided with N number of aperture, and N is natural number；Described passage is arranged on outside fuel tank.
Can generate heat in oil pipe during existing conventional hydraulic long-term work, the accumulation effect of generation can cavitate, damage pump head or
Pipeline.In order to solve this problem, the present invention improves in terms of 3, first aspect increase cavity at hydraulic oil from low
Place hoist transmission position, from lower toward eminence effect be need more energy and extrude generation substantial amounts of heat energy, lead
Cause temperature during hydraulic oil incoming separatory cylinder pressure too high.So the present invention adds cavity and operationally at cavity inside in this position
Adding dry ice to lower the temperature, second aspect increases air-permeable layer, can become water when understanding the dry ice cooling of cavity due to heat transfer
Steam, arranges aperture in air-permeable layer and steam is distributed from little empty position, be so further to change on the basis of cavity
Kind, because steam is in whole air-permeable layer cavity, moreover it is possible to take away the heat on oil pipe surface, so ratio and directly arrange cavity by water
Steam effect of freely volatilizing is more preferable, and the 3rd aspect arranges passage at fuel tank, when ambient temperature amplitude of variation too when hold
Easily fuel tank internal assembles steam, and this is can to open passage heat radiation to be avoided analysis of hydraulic oil overheat.
Connect between described stop valve and fuel tank and have Pressure gauge, a Pressure gauge is set and can check pressure more intuitively
Power changes, and preferably controls hydraulic system.
The material of described air-permeable layer is copper, the good heat conduction effect of copper, and price material benefit.
Described main hydraulic cylinder connects motor, and conventional hydraulic uses manual pump mode oil-feed, wastes time and energy, and the present invention adopts
With motor mode oil-feed, the pointing out and save the time of economical manpower.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the hydraulic system of heating is avoided in a kind of automatic cooling of the present invention, and fuel tank arranges passage, when ambient temperature amplitude of variation
The when of too, easy fuel tank internal assembles steam, and this is can to open passage heat radiation to be avoided analysis of hydraulic oil overheat；
2, the hydraulic system of heating is avoided in a kind of automatic cooling of the present invention, arranges aperture in air-permeable layer and makes steam from little room
Put and distribute, be so further to improve on the basis of cavity, because steam is in whole air-permeable layer cavity, moreover it is possible to take away
The heat on oil pipe surface, the quantity of aperture can be according to free setting；
3, the hydraulic system of heating is avoided in a kind of automatic cooling of the present invention, arranges a Pressure gauge and can check pressure more intuitively
Power changes, and preferably controls hydraulic system.
