Abstract
The utility model relates to a pressure type pan seal oil, belongs to the mechanical field and comprises an oil tank body, a compression spring, a piston, a seal ring, a guide cap and a piston guiding sleeve; wherein, the guide cap is connected with the oil tank body through bolts, and forms a pan seal cabinet by pressing the spring; the compression spring is arranged between the piston and the guide cap; the piston guiding sleeve is fixed on the guiding base of the oil tank body through the bolts. The utility model has practical structure and is convenient in process, and is economical, simple with good performance, and is free of air bubbles and air when using, and is mainly applied in the subterranean tunnel shield construction as electric power, water conservation, traffic and urban water supply and drainage. The preset reinforced concrete pipe pieces are assembled as a ring in the tunnel under the hydraulic oil supplied by the oil tank.
Description
Technical field
The utility model relates to the pressurized sealed oil tank of a kind of fuel tank, particularly shield excavation machine, belong to mechanical field.
Background technique
Find by literature search: " mechanical design handbook " 19-585 page or leaf, this (Chemical Industry Press) and " the pocket pneumatic handbook of hydraulic pressure " the 417th page of the third edition in 1993, version in 1998 (China Machine Press) is introduced, all kinds of fuel tanks in the fuel tank design, even the circular fuel tank end face of big capacity also is a level, do not have the inclined-plane designing requirement and the example of circular arc again, relief opening and oil filler all are designed on same horizontal line.According to above-mentioned handbook introduction; Fuel tank divides two classes: a class is an open type oil tank, and a class is sealed reservoir (pressurized reservoir), and sealed reservoir is that liquid level directly is not communicated with atmosphere, fills with the inert gas less than 0.05Mpa shape employing rectangle in the case in the case.This fuel tank is owing to the inert gas that fills with certain pressure, improved the content of gas in fluid in the fuel tank, so pressurized reservoir, only should be used in necessary static special occasions, simultaneously, the pressure inert gas enter the small-sized air compressor that will use 0.7～0.8MPa, earlier aeration tank is full of gas during work, again by the filtering of aeration tank process, drying, the decompression back feeds on the fuel tank liquid level, the pressure GPRS is suitable during inflation, in order to avoid dissolve in excessive gas in the fluid, excessive for preventing pressure, air tank also will be provided with safety valve, for avoiding underpressure, need to be equipped with pressure gauge with electric contact and alarm,, can not realize revolution though this fuel tank can be realized forced feed, the fuel tank revolution can make the interior gas of fuel tank sneak in the fluid, makes hydraulic work system undesired.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, a kind of fuel tank is provided, can be applied in that a certain equipment need turn round or simultaneously about, move forward and backward and adopt hydraulicdriven occasion, it is pressure type spring closed tank that hydraulicdriven fuel tank is provided, can realize revolution, and not produce bubble with equipment; Oil box is an arc top ladder structure of right angle, helps the whole discharges of air in the fuel tank are not sneaked in the fluid, guarantees that oil pump do not draw the fluid that contains bubble.
The utility model is achieved through the following technical solutions, the utility model comprises: oil box, pressure spring, piston, seal ring, piston guide bush, the guiding cover bolt is connected with oil box, the while holddown spring, then form a totally enclosed casing, casing is arc top right-angled trapezium section, is a hermetic steel structure body, and the fluid in the fuel tank can not leak outside.Piston guide bush is by on the guide seats that is bolted to oil box.Pressure spring is arranged between piston and the guide cover, and spring length can change with the variation of oily volume.Piston moves with the internal surface of fluid variation along piston guide bush, is unique moving body in the fuel tank.Seal ring is separately fixed on piston guide bush and the piston, and the fluid in the fuel tank can not leaked outside.
Pressure spring is arranged on the certain precompression of generation between piston and the guide cover, spring length can change with the variation of oily volume, when casing inner fluid volume-variation, under the effect of pressure spring, piston promptly produces flexible, in time adapts to the variation of oily volume in the fuel tank.Oil pressure is in less than the 0.2MPa scope in the oil box.
Pressurized sealed oil tank need not any equipment for public use, only system all be provided with qualified after, in fuel tank, refuel, get final product when relief opening overflows fluid.Pressurized sealed oil tank belongs to the hermetically sealed fuel tank of no air pressure formula
The utlity model has structure practicality, easy to process, simple, economic, effective, do not produce bubble, not entrained air in the use.Be mainly used under the hydraulic oil that fuel tank provides, prefabricated steel concrete section of jurisdiction being assembled into ring in the tunnel in the subterranean tunnel shield-tunneling constructions such as electric power, water conservancy, traffic, municipal plumbing.
