Abstract
The utility model discloses a hydraulic dismantling device for a cap nut of a membrane chamber, and relates to improvement of a structure of the hydraulic dismantling device for the cap nut of the membrane chamber. The utility model provides the hydraulic dismantling device for the cap nut of the membrane chamber, which is labor-saving for assembly and disassembly, and is capable of improving the working efficiency. The hydraulic dismantling device comprises a pressure bearing ring provided with a hydraulic groove at the surface, and is characterized in that a plunger is arranged in the hydraulic groove, a position at the side of the pressure bearing ring, which corresponds to the hydraulic groove, is provided with an oil inlet; the middle of the plunger is provided with a through hole corresponding to a stud of the membrane chamber, and a fixed nut matched with the stud of the membrane chamber is arranged outside the membrane chamber.
Description
Technical field
The utility model relates to a kind of improvement of diaphragm chamber cover screw nut hydraulic extracting tool structure.
Background technology
Chamber of septum in the membrane pump is one of critical component of membrane pump equipment, and it bears high pressure, and the impact of highly corrosive slip, wearing and tearing need regular maintenance and maintenance, and changes inner consumable accessory--the barrier film of diaphragm cavity; Especially for the high-pressure high-flow membrane pump, the chamber of septum pressure-bearing is higher, and double-screw bolt quantity is more, and the double-screw bolt pretightning force is large, so that the nut of dismounting diaphragm chamber cover is very inconvenient, extremely is necessary to design a kind of easily diaphragm chamber cover nut dismounting tool.
Summary of the invention
The utility model is exactly for the problems referred to above, provide a kind of remove and install laborsaving, and the diaphragm chamber cover screw nut hydraulic dismantling device that can increase work efficiency.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises that the surface has the bearing ring of hydraulic pressure groove, its structural feature: be provided with plunger in the hydraulic pressure groove, the bearing ring side is provided with oil-in corresponding to the hydraulic pressure groove; Be provided with the corresponding through hole of chamber of septum double-screw bolt in the middle of the plunger, plunger is outside equipped with the hold-down nut that matches with the chamber of septum double-screw bolt.
As a kind of preferred version of the present utility model, described plunger is set to stepped.
The beneficial effects of the utility model: when the utility model uses, the through hole of chamber of septum double-screw bolt by plunger passed, and by hold-down nut the chamber of septum double-screw bolt is fixed as one with the utility model; By injection liquid force feed in the hydraulic pressure groove, make plunger jack-up, by hold-down nut the chamber of septum double-screw bolt is elongated; Make that frictional force reduces between itself and the chamber of septum nut, then use spanner to pull the diaphragm chamber cover nut, can make the dismounting of diaphragm chamber cover nut more convenient, solve diaphragm chamber cover nut artificial unloading and inconvenient problem is installed, improve the operating efficiency of chamber of septum maintenance.
In addition, plunger of the present utility model is set to stepped, can effectively utilize hydraulic coupling, and is during use, more laborsaving.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
1 is that bearing ring, 2 is that oil-servicing facilities, 3 is that hold-down nut, 4 is that plunger, 5 is that oil-in, 6 is that hydraulic pressure groove, 7 is that chamber of septum double-screw bolt, 8 is that chamber of septum nut, 9 is spanner in the accompanying drawing.
The specific embodiment
The utility model comprises that the surface has the bearing ring 1 of hydraulic pressure groove 6, is provided with plunger 4 in the hydraulic pressure groove 6, and bearing ring 1 side is provided with oil-in 5 corresponding to hydraulic pressure groove 6; Be provided with chamber of septum double-screw bolt 7 corresponding through holes in the middle of the plunger 4, plunger 4 is outside equipped with the hold-down nut 3 that matches with chamber of septum double-screw bolt 7.
As a kind of preferred version of the present utility model, described plunger 4 is set to stepped.
The number of described plunger 4 and hydraulic pressure groove 6 is identical with the number of chamber of septum double-screw bolt 7, is interconnected between hydraulic pressure groove 6 and the hydraulic pressure groove 6.
Below in conjunction with description of drawings one-off process of the present utility model: during dismounting chamber of septum nut 8, bearing ring 1 is pressed on the diaphragm chamber cover, the through hole of plunger 4 is passed chamber of septum double-screw bolt 7 cooperate with bearing ring 1, hold-down nut 3 is matched with chamber of septum double-screw bolt 7, and be tightened against on the plunger 4.
Use oil-servicing facilities 2, to hydraulic pressure groove 6 interior adding hydraulic oils, hydraulic oil is with plunger 4 jack-up by oil-in 5, and the hold-down nut 3 on plunger 4 surfaces elongates chamber of septum double-screw bolt 7, has reduced chamber of septum nut 8 and chamber of septum double-screw bolt 7, and the frictional force between the diaphragm chamber cover; By spanner 9, can easily chamber of septum nut 8 be unloaded.
When chamber of septum nut 8 is installed, first chamber of septum nut 8 is installed on the chamber of septum double-screw bolt 7, again the utility model also is fixed as one with chamber of septum double-screw bolt 7; To hydraulic pressure groove 6 interior adding hydraulic oils, hold-down nut 3 elongates chamber of septum double-screw bolt 7 by oil-in 5; By spanner 9 with nut screwing clamping; After discharging the oil pressure in the hydraulic pressure groove 6, chamber of septum double-screw bolt 7 shortens, and for chamber of septum nut 8 provides pretightning force, has reduced the labour intensity the when workman installs chamber of septum nut 8.
