Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Basic ideas of the present utility model are: first arc sealing and two V-seals are installed, form packing assembly 3, be then pressed in plunger cavity 6 by this packing assembly 3 with frock is disposable.Because arc sealed material is softer, good guide effect can be played, as long as with the assembling of frock gently inward with packing assembly 3 just can be realized.
As shown in Figure 1 to Figure 2, a kind of packing installation frock, comprise dish seat 1, backstay 2 and pull bar 4, the left end of pull bar 4 is removably fixedly installed in the middle part of dish seat 1, dish seat 1 along the circumferential direction at least offers one group of installing hole, backstay 2 is removably fixedly installed on described dish seat 1 by this installing hole, and packing assembly 3 is sheathed on backstay 2, and backstay 2 and described pull bar 4 are all arranged on the left side of dish seat 1.By above-mentioned setting, backstay 2 is fixed on after in installing hole for determining the internal diameter of packing assembly 3, pull bar 4 is for being with Moving plate seat 1, and then drive the packing assembly 3 on backstay 4 to move, packing assembly 3 delivers to appointed place (in the plunger cavity 6 in pump head body 7) the most at last, realizes the installation of packing assembly 3.It should be noted that, the middle part of dish seat 1 preferably offers a screwed hole, and the left end of pull bar 4 is removably fixedly connected with dish seat 1 by this screwed hole.
Further, for better packing assembly 3 being delivered to infield, backstay 2 is provided with step, packing assembly 3 is sheathed on described step place, this step is used for applying pressure to packing assembly 3, and as shown in Figure 1, aforementioned step applies pressure left to packing assembly 3.It should be noted that, backstay 2 has certain length, and this length can ensure packing assembly 3 to be all in place and coil seat 1 and can not interfere with pump head body 7.
Simultaneously, for the installation of the packing assembly 3 of different-diameter can be met, dish seat 1 is along the circumferential direction provided with and organizes installing hole more, position, the hole diameter of the installing hole of different group is all not identical, particularly, the many groups installing hole offered from inside to outside, meets the size of packing assembly 3 under the different diameters of plunger such as 3.75 inches, 4 inches, 4.5 inches.It should be noted that, for easy for installation, aforementioned installing hole is also preferably screwed hole, obvious backstay 2 is then provided with the external screw thread matched with the internal thread of this screwed hole.But it is worth mentioning, other can realize installing installing holes of effect also also in protection domain of the present utility model, in this citing that differs.
In addition, in aforementioned many group installing holes, the aperture of installing hole is all identical, and often the installing hole organized in installing hole is circumferentially evenly arranged, by above-mentioned setting, the versatility of backstay 2 can be improved on the one hand, also can ensure the packing assembly 3 all directions uniform force on backstay 2 on the other hand, comparatively effortlessly packing assembly 3 be delivered to appointed place.
Preferably, in the utility model, the quantity of pull bar 4 is four, and the quantity often organizing installing hole in installing hole is four, and one end of every root pull bar 4 is installed in one group of identical installing hole of position, hole diameter respectively.Be embodied in: four backstays 2 with external screw thread and step are installed on dish seat 1, and then surround a circle, if the packing assembly 3 installed is 3.75 inches, then four backstays 2 are arranged in first group of installing hole of most inner face of dish seat 1, if the packing assembly 3 installed is 4 inches, then four backstays 2 are arranged in second group of installing hole on dish seat 1, by that analogy.
As shown in Figure 2,1 is tried to get to the heart of a matter for the pump head body 7 better from fracturing pump fluid end a bit pulls in addition, aforementioned packing installation frock also comprises handle 5, handle 5 is specifically arranged at the right-hand member of pull bar 4, and the setting direction of the right-hand member of pull bar 4 perpendicular to pull bar 4 offers through hole, this handle 5, through described through hole, moves left and right for driving pull bar 4 level, and then realize by packing assembly 3 integral installation in the plunger cavity 6 of pump head body 7, install comparatively laborsaving.
Fig. 3 is the assembling schematic diagram that packing assembly is mounted on pump head body by the utility model packing installation frock.During installation, first arc sealing and two V-seals are installed, form packing assembly 3, then four backstays 2 are fixedly mounted on and try to get to the heart of a matter on 1, then packing assembly 3 is sheathed with the step place on backstay 2, and the parts assembled are placed the suction cover place (Figure 3 shows that the right-hand member of pump head body 7) of pump head body 7, then pull bar 41 to be fixedly connected with through pump head body 7 (from left to right through pump head body 7 shown in Fig. 3) and with trying to get to the heart of a matter, finally handle 5 is arranged on pull bar 4, finally realize this packing assembly 3 to be pressed in plunger cavity 6 by pulling handle 5 (Figure 3 shows that and pull handle 5 left), complete installation.Because arc sealed material is softer, good guide effect can be played, as long as with the assembling of aforementioned frock gently inward with packing assembly 3 just can be realized.
In sum, the utility model discloses a kind of packing installation frock, comprise dish seat 1, four backstays 2, pull bar 4 and a handle 5.Dish seat 1 offers successively by position, different hole diameter and organizes installing hole more, the installation of the packing assembly 3 of different-diameter can be met.Backstay 2 one length of tape has external screw thread, and be conveniently connected with dish seat 1, one section has step, for applying pressure better to packing assembly 3, packing assembly 3 is pressed in the plunger cavity 6 of pump head body 7.Backstay 2 has certain length, packing assembly 3 can be made to be installed to correct position and coil seat 1 and be unlikely to interfere with pump head body 7.Pull bar 4 is long draw, makes pull bar 4 can put in together with coiling seat 1 and combining from the left end of pump head body 7 like this, and one end of pull bar 4 is threaded with dish seat 1, the other end offers through hole, for mounting handle 5, handle 5, through the through hole of pull bar 4, realizes pulling function.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
