Hydraulic pressure system is a kind of support intensity of pressure of change of hydraulic pressure force adds equipment of hydraulic pressure of your work emphatic thereby, a whole hydraulic pressure system includes 5 much, namely dynamical cell, executive component, control component, back-up component and working medium, among them back-up component reachs ball valve of pipe fittings, sealing ring, hydraulic quick coupler, high pressure, glue to manage assembly for gasoline tank, oil purifier, vitta respectively, measure crimp watch of head, pressure and oil level oil are lukewarm plan etc, article general with " gasoline tank " give for key classify explain. Above all, is gasoline tank how define? Learned, hydraulic pressure gasoline tank is to be used at storing to make sure place of work of hydraulic pressure system needs oily fluid to be in special container, the aviation science and technology that uses course to include one degree course and the aviation Electromechanical system of 2 degree course. Press recently the requirement with academic control of pollution of hydraulic pressure system, gasoline tank should not be to accommodate bilge to be in container, its ask the oily fluid itself in gasoline tank should achieve certain cleanness to spend grade, the working return that provides hydraulic pump and system of whole hydraulic pressure with clean oily fluid, the design because of this gasoline tank, make, safeguard with use should accord with corresponding requirement. On component design, oil absorption is in charge of and answer vitta to should maintain certain distance as far as possible, want to be separated with clapboard between two canals, in order to add space of oily fluid loop, make oily fluid has enough time depart bubble, precipitation impurity, abreaction quantity of heat, will tell clapboard height to should be height of face of the oil inside box in 3/4 commonly optimal. A vitta of gasoline tank should as far as possible face of juice of locate oily juice is the following, lest answer oily oily fluid to pound range of juice of juice of the oil inside gasoline tank, make oily fluid produces bleb to cause cavitation thereby, this will cause a series of undesirable effects to hydraulic pressure system. On main function, its include oil of deposit hydraulic pressure fluid, medicinal powder gas of clean of hair-oil fluid quantity of heat, excessive and remove bubble and installation element in all 4 kinds, specific content is as follows respectively: (1) in can depositing hydraulic pressure system, gasoline tank of oily fluid of deposit hydraulic pressure must work system of the oily amount that requires circularly, hydraulic pressure smokes oily fluid to send to the system from gasoline tank inside, ability makes oily fluid returns gasoline tank again after motivation is finished to deliver inside the system; (2) medicinal powder the cubage loss in process of work of system of hydraulic pressure of hair-oil fluid quantity of heat and mechanical loss bring about oily fluid temperature to lift, oily fluid brings back from inside the system have in quantity of heat very big one part relies on oily fluid wall to send out all round in air, this asks oily fluid needs to have adequate measure, install as far as possible in drafty locally, when necessary the wall outside oily fluid should install a wing piece come loose in order to increase heat energy force; (3) excessive clean gas and eliminate pressure of meiobar of system of bubble hydraulic pressure to be in charge of under saturated evaporate steam pressure, oil absorption when flat or fluid area is too small, cause pump by eddy action induction air and answering oily agitate to move action to wait is the reason that forms bleb. Oily vacuole foam can cause grating noise and attaint hydraulic pressure is installed buy, may cause cavitation in hydraulic pump especially, not deliquescent air can spill over in gasoline tank, because this hopes,oily fluid area wants as far as possible big, and can make oily fluid can keep longer time in gasoline tank. (4) installation component is in the hydraulic pressure system of medium, small-sized equipment, meet normally install hydraulic pump group and partial a powerful person or team of whole a powerful person or family on gasoline tank coping directly, gasoline tank must be made enough firm in order to prop up these component, this kind of setting still conduces to the noise with be reduced certain. The structure as a result of gasoline tank and utility somewhat difference, its can divide normally it is 3 kinds big: Integral type gasoline tank, amphibious gasoline tank and independent gasoline tank, specific content is as follows: (1) gasoline tank of type of whole of integral type gasoline tank is the gasoline tank that points to to be formed inside the component in hydraulic pressure system or machine. E.g. , the in-house cavity of the lathe bed of of all kinds machine tool in industrial machinery or base often slightly trifling cost can be made do not leak oily gasoline tank, or the position such as bottom of step of fluctuation of the canal on car and project machine component, cab uses as gasoline tank, do not need extra additional space so. Integral type gasoline tank is OK the least space provides the greatest performance, and can offer relatively neat outward appearance normally. Notable is, its are designed must attentive, what exist in order to overcome a likelihood is local and calorific be close to hard with handlers wait for working issue; (2) amphibious gasoline tank is amphibious gasoline tank is the public gasoline tank that the other purpose in pointing to hydraulic pressure oil and machine uses oil. E.g. , tractor drive fastens housing to be able to use the gasoline tank that makes system of suspension of tractor hydraulic pressure, or it is to use the gear of fluid drive to quench machine cavity base, hold <> concurrently do hydraulic pressure system and quench the gasoline tank that uses oil. The biggest advantage of amphibious gasoline tank depends on saving a space, but its also have a part to limit a condition. It is oily fluid above all must satisfy hydraulic pressure system to be opposite already the requirement of transmission medium, can satisfy transmission to fasten gear again lubricant or the job quenchs the corresponding requirement that waits for other technology purpose. In system of certain high-powered hydraulic pressure, these requirements as far as possible each other is antipathic. In addition, control of oily fluid temperature also has difficulty relatively, will tell existence to wear because of the oily fluid that decreased to gross two heat source, if must set condenser additionally to control oil lukewarm, the space that the space that needs with condenser place offsets place is saved possibly. (3) gasoline tank of independence of independent gasoline tank is a kind of gasoline tank with most wide application, its are the commonnest in industrial production facilities, to get used to working requirement, normally by make it rectangular, cylindrical or oilcan form. The quantity of heat of independent gasoline tank basically is to pass gasoline tank wall to rely on radiation and convection action to send out, so gasoline tank should be as far as possible narrow and tall figure. Canal of hydraulic pump oil absorption is under fluid face or above crosses gasoline tank sidewall to enter gasoline tank, if suck vitta to enter gasoline tank below in fluid face, criterion gasoline tank oily fluid is being pressed supply hydraulic pump, improved hydraulic pump to be in oil absorption condition, but box is discharged to put oil when so that overhaul,shut-off valve must be being installed on oil absorption canal. Outside removing type of these 3 kinds of common oil pump, still can be interlinked to differentiated according to face of gasoline tank fluid and air, leave namely type and shut type two kinds. Application of gasoline tank opening type is the widest, face of the fluid in gasoline tank and air are interlinked, to reduce oily fluid pollution, the setting answers to aerate on gasoline tank coping filter, make the air classics filter inside atmosphere and gasoline tank is interlinked. Apply in gasoline tank in damp area place, aerate the desiccative that sets certain amount still should be added on filter. The gasoline tank that shut type can be divided again for segregation type is mixed charge type two kinds. Segregation type gasoline tank has again take fold implement and take flexibility isolator two kinds of structures, when hydraulic pump works, fold implement or flexibility isolator contracts or expand, make fluid face retains atmosphere power, and outside air is not contacted with fluid of the oil inside gasoline tank again. General fold implement or the value of the largest flow that the bulk of flexibility isolator should compare hydraulic pump is great 25% above. Press under atmosphere to avoid pressure of face of the fluid inside gasoline tank force, need to install low pressure additionally warning apparatus, automatic stop gear or automatic and urgent filling oil unit. Charge in type gasoline tank, gasoline tank should close completely, connect course filter and dry air, charge baric force (more tallish than atmosphere) by set of pressure-relief valve place, it is normally 0.


07MPa. To avoid pressure undeserved, should set watch of pressure of contact of relief valve, report and warning apparatus. Because increase gasoline tank pressure in order to added content of the airy in oily fluid, because this is filled,press gasoline tank to be used at really necessary special situation only (wait like system of jetliner hydraulic pressure) .
