Embodiment
Core of the present invention is to provide a kind of oil-gas separator leak-checking apparatus.It is groundwork element that this device be take cylinder and shutoff fixture etc., utilizes the coordination of control system implement device, realizes the leak hunting robotization of operation of oil-gas separator, thus the process efficiency of leaking hunting of raising oil-gas separator.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
First, the structure of a kind of typical oil-gas separator in prior art is introduced, the leak-checking apparatus in embodiment designs mainly for this oil-gas separator.
Please refer to Fig. 1, the structural representation that Fig. 1 is a kind of typical oil-gas separator.
As shown in the figure, housing 1 one end of oil-gas separator is provided with the draft tube 2 being communicated with inner chamber, the other end is provided with the escape pipe 3 being communicated with inner chamber, bottom surface is provided with the scavenge pipe 4 being communicated with inner chamber, in the inner chamber of housing 1, be connected with " U " shape groove baffle plate 5 of two groups of arranged crosswise, the upper end of baffle plate 5 and housing 1 inner top surface close contact, lower end and housing 1 inner bottom surface leave gap, the labyrinth passage that it is inner, the air-fuel mixture gas that can guarantee high temperature is detained the sufficiently long time in the inner chamber of housing 1, and the heat radiation contact area of effective increase and baffle plate 5, the temperature fall of high-temperature oil gas mixed gas is increased, the drop of condensation increases, thereby raising oil gas separation.
Please refer to Fig. 2, Fig. 3, Fig. 2 is the structural representation of a kind of embodiment of oil-gas separator leak-checking apparatus provided by the present invention; Fig. 3 is the vertical view of oil-gas separator leak-checking apparatus shown in Fig. 2.
In a kind of embodiment, oil-gas separator leak-checking apparatus provided by the invention mainly consists of parts such as water tank 10, worktable 11, shutoff fixtures.
Water tank 10 is rectangular, and by tank bracket, 10-1 supports, and bottom is provided with ajutage 10-2.
Worktable 11 is a smooth rectangle back up pad, and its undersized is in water tank 10, so that move up and down in water tank 10 under the driving of lift.
Lift is by being positioned at water tank 10 both sides, by lift cylinder 12-1 and the support 12-2 that rises and falls, formed, lift cylinder 12-1 is fixed on water tank 10 outer walls by support, quantity is four, each two of one sides, its piston rod end is connected with the worktable 11 of a corresponding side by the support 12-2 that rises and falls, and the support 12-2 that rises and falls is " several " font substantially, to make way for water tank sidewall in lifting process.
Worktable 11 is provided with three groups of shutoff fixtures, each group shutoff fixture forms by parts such as support, cylinders, wherein, support comprises the first fixed support 13-1, the second fixed support 13-2 and the 3rd fixed support 13-3, and cylinder comprises clamping cylinder 14-1, lower clamping cylinder 14-2 and side clamping cylinder 14-3.
Particularly, the first fixed support 13-1 is the oblique bent plate that is fixed on worktable 11, it is bending on Width, its oblique part connecting working table 11 installation side clamping cylinder 14-3, center line and worktable 11 form angle, side clamping cylinder 14-3 is positioned at lower right and the oblique layout of clamping cylinder 14-1, and its piston rod points to upper left side; The longitudinal component of the first fixed support 13-1 overhangs worktable 11 and installs clamping cylinder 14-1, and upper clamping cylinder 14-1 vertically arranges, below its piston rod points to.
The lower clamping cylinder 14-2 of the upper installation of the second fixed support 13-2, the piston rod cardinal principle of lower clamping cylinder 14-2 is perpendicular to the plane at upper clamping cylinder 14-1 and side clamping cylinder 14-3 place.
The 3rd fixed mount 13-3 is for the draft tube 2 of supporting oil gas separating device, and it is positioned at the front side of lower clamping cylinder 14-2 piston rod and seal.
Upper clamping cylinder 14-1, lower clamping cylinder 14-2 and side clamping cylinder 14-3 are corresponding with the position of escape pipe 3, draft tube 2 and the scavenge pipe 4 of oil-gas separator fixed pose respectively, the piston rod end of each cylinder is equipped with the seal 15 of its corresponding mouth of pipe of shutoff, wherein descend the seal of clamping cylinder 14-2 to be provided with air admission hole 16, during work, air admission hole 16 is connected with air compressor exhaust port by pipeline.
Certainly, air admission hole 16 also can be arranged on the seal of clamping cylinder 14-1 or side clamping cylinder 14-3, as long as can be filled with test gas in oil-gas separator inner chamber.
Here it should be noted that, Figure 1 shows that the operating attitude of oil-gas separator, fixed pose when it leaks hunting need to be on the basis of Fig. 1 90-degree rotation counterclockwise.
Seal 15 adopts silica gel plates, and silica gel plate good airproof performance is not prone to the situations such as plugging effect is bad with its shutoff mouth of pipe, can guarantee the work quality of the work of leaking hunting.
For ease of it being carried out to Primary Location when oil-gas separator is placed on worktable, the first fixed support 13-1 is provided with and coordinates the locating piece 17 clamping with side clamping cylinder 14-3, and both can remain on oil-gas separator on worktable 11 by the scavenge pipe 4 of clamping oil-gas separator.
As can be seen from the figure, three groups of shutoff fixtures on worktable 11 according to a determining deviation, in the mode tilting, be arranged side by side, can make full use of table space like this, after inclination, the plane at upper clamping cylinder 14-1 and side clamping cylinder 14-3 place (i.e. the plane at the first fixed support 13-1 place) just forms angle with the cross central line of worktable 11.
While using above-mentioned oil-gas separator leak-checking apparatus to leak hunting work, first energising air-supply, secondly, press start button, lift cylinder 12-1 push work platform 11 rises, then toward 10 li, water tank, be filled to a certain amount of, then, oil-gas separator is placed on worktable 11, start gauge tap, upper clamping cylinder 14-1 is passed through in time delay for two seconds afterwards, lower clamping cylinder 14-2, side clamping cylinder 14-3 clamps and seals, then by air admission hole 16 inflation pressure testings, when inflation, worktable drops in water tank 10 automatically, the pressure testing time is 11 seconds, to check whether oil-gas separator has gas leak phenomenon, more than worktable 11 is raised up to the water surface automatically afterwards, so far the operation of once leaking hunting completes.
In order to prevent being down in process under water and having spray to splash at worktable 11, on worktable 11, offer the rectangular tank 11-1 that allows in three roads.
Can expect, the elevating mechanism of worktable 11 can also adopt other to exercise, for example, lift is set up in to water tank top, or adopts the modes such as hydraulic cylinder, rack-and-pinion, screw-nut to drive etc., can be used for realizing the object of the invention.
Certainly, above-described embodiment is only preferred version of the present invention, is specifically not limited to this, can make according to actual needs pointed adjustment on this basis, thereby obtains different embodiments.For example, when the structure of oil-gas separator changes, can adjust accordingly the cylinder location corresponding with its each mouth of pipe, or substitute cylinder etc. with hydraulic cylinder, because mode in the cards is more, just illustrate no longer one by one here.
Above oil-gas separator leak-checking apparatus provided by the present invention is described in detail.Applied specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment is just for helping to understand core concept of the present invention.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
