Abstract
The invention relates to a double-chamber structure of a dry gas seal testing cavity. The double-chamber structure comprises chambers and a main shaft. Each chamber is of a cylindrical barrel structure, the two ends of each chamber are coaxially and symmetrically provided with two water sleeves, the two water sleeves and the chambers are fixedly arranged respectively, the main shaft is coaxially arranged in the two water sleeves, the two ends of the main shaft are movably arranged together with the chambers respectively through end covers, and dry gas seal components are arranged between the main shaft and the water sleeves respectively. The double-chamber structure can accommodate two dry gas seal components at the same time, so that work efficiency is effectively doubled, in addition, the dry gas seals in rotation can be quickly cooled through the water sleeves, a water inlet and a water return opening, the dry gas seals can be taken down right away after the testing is finished, and work efficiency is effectively improved.
Description
Technical field
The invention belongs to dry gas seals technical field, specifically, is a kind of double-cavity structure of dry gas seals test cavity.
Background technology
Dry gas seals, when carrying out dynamic and static test, is normally placed in a test cavity, then test cavity is placed on test board and is tested.
Traditional cavity can only hold a set of dry gas seals, so detection efficiency is low.In addition, owing to producing a large amount of heats in test, therefore after off-test, can not take off product at once, must wait product and test after cavity is cooled to room temperature and just can change product to be detected, thereby causing work efficiency low.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of dry gas seals simple in structure, raising experiment work efficiency to test the double-cavity structure of cavity.
The solution of the present invention is achieved in that
A kind of double-cavity structure of dry gas seals test cavity, comprise chamber and main shaft, this chamber is cylindrical tube body structure, described chamber two ends are coaxial is symmetrically installed with two water jackets, these two water jackets are solidly installed with chamber respectively, the coaxial main shaft of installing in two water jackets, these main shaft two ends are separately installed with dry gas seals assembly together with being movably arranged on cavity respectively by end cap between described main shaft and water jacket.
And, the outer rim of described each water jacket is radially evenly shaped with a plurality of inclined holes, cavity outer rim that should inclined hole is radially shaped with respectively to the air intake opening being communicated with it, cavity outer rim between coaxial two air intake openings is radially shaped with inner seal leakage hole, in the cavity outer rim end of coaxial two air intake opening outer ends symmetry, be radially shaped with outside seal leakage mouth, the cavity outer rim opposite side lateral symmetry of corresponding described inner seal leakage hole is shaped with two water inlets, outside two water inlets, symmetry is shaped with two water return outlets, described water inlet is communicated with the aqua storage tank that water jacket outer rim is shaped with respectively with water return outlet.
Advantage of the present invention and good effect are:
This double-cavity structure can hold two dry gas seals assemblies simultaneously, the work efficiency that therefore can effectively double; In addition, by water jacket, water inlet and water return outlet, can be fast to the dry gas seals in rotation, carry out fast cooling, take off dry gas seals assembly at once after can realizing thus off-test, therefore effectively improve work efficiency.
Accompanying drawing explanation
Fig. 1 is structure cut-open view of the present invention.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the invention will be further described.
A kind of double-cavity structure of dry gas seals test cavity, as shown in Figure 1, comprise chamber 6, water jacket 4, main shaft 5, this chamber is cylindrical tube body structure, these chamber two ends are coaxial is symmetrically installed with two water jackets, and these two water jackets are solidly installed by baffle plate 2 and chamber respectively, the coaxial main shaft of installing in two water jackets, these main shaft two ends are separately installed with dry gas seals assembly (not shown) together with being movably arranged on cavity two ends by end cap 1 respectively between described main shaft and water jacket.
The outer rim of described each water jacket is radially evenly shaped with a plurality of inclined holes 3, the cavity outer rim of corresponding each inclined hole is radially shaped with respectively the air intake opening B being communicated with it, cavity outer rim between coaxial two air intake openings is radially all shaped with inner seal leakage hole C, in the cavity outer rim end of coaxial two air intake opening outer ends symmetry, be radially shaped with outside seal leakage mouth A, the cavity opposite side outer rim lateral symmetry of corresponding described inner seal leakage hole is shaped with two water inlet E, the aqua storage tank 7 that these two water inlets are shaped with water jacket outer rim is respectively communicated with, the cavity outer rim in these two water inlet outsides is radially shaped with respectively two water return outlet D that are communicated with aqua storage tank.
This double-cavity structure can hold two dry gas seals assemblies simultaneously, the work efficiency that therefore can effectively double; In addition, by water jacket, water inlet and water return outlet, can be fast to the dry gas seals in rotation, carry out fast cooling, take off dry gas seals assembly at once after can realizing thus off-test, therefore effectively improve work efficiency.
It is emphasized that; embodiment of the present invention is illustrative; rather than determinate; therefore the present invention includes and be not limited to the embodiment described in embodiment; every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention, belong to the scope of protection of the invention equally.
