Abstract
The utility model discloses a special tool for installing a seal packing in a plunger tpe water pump, and solves the problems that time and labor are wasted when a packing is changed for a water injection well, and the service life of the packing is short. The special tool specifically comprises a fixed seat, a pushing part, a tension spring and a force applying mechanism, wherein the pushing part which is inserted into the fixed seat can move left and right along the track of the fixed seat, and the pushing part and the fixed seat are fixedly connected via the tension spring; two check blocks are welded on the fixed seat; two support legs are welded on the pushing part; semi-disc cams are respectively welded to the left end of two straight shafts of the force applying mechanism, the two semi-disc cams are respectively connected with the two support legs via pin shafts, and the two semi-disc cams and the two check blocks respectively form a cam mechanism. Due to the use of the tool, the time for replacing the packing is shortened, the service life of the packing is prolonged, the labor intensity of water injection pump operators is reduced, and material cost is reduced at the same time.
Description
Technical field
The utility model relates to a kind of sealed packing and adds holding tool.
Background technology
On oil field, existing plunger type water pump is changed a packing in average every 3 days, and each pump has 5 plungers, and each plunger need add 5 packings, so in oilfield process, change the workload of packing or sizable to water injecting pump.In replacing, install in the process of packing; to adding the operation of packing very time-consuming in plunger, effort; because there is no special instrument; workpeople uses copper rod to knock in rigid packing conventionally; knock in process and often fluid end rod surface can be got to pit; thereby damage the surface gloss of fluid end connecting rod; and then cause the phenomenon that packing_seal is not tight to occur; and the packing after changing is like this in use more fragile; cause the cycle of changing packing to shorten, having wasted raw material has affected again manufacturing schedule.
Summary of the invention
The purpose of this utility model is to provide a kind of plunger type water pump and adds sealed packing specific purpose tool, use this instrument to add packing and not only can obviously improve the speed of installing additional, and the packing_seal performance after adding is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of plunger type water pump adds sealed packing specific purpose tool, comprise: holder, yoke frame, tension spring and boosting mechanism, wherein, the main body of holder and yoke frame is semi-circular tube, along the two straight flanges welded rails respectively of holder semi-circular tube, yoke frame is inserted in holder along rail moving, between holder and yoke frame, be also fixedly connected with tension spring, on holder, weld two blocks, the right flank of two blocks is all concordant with the right side of holder; On described yoke frame, weld two supporting legs and two extension devices, two supporting legs and two extension devices are symmetrical in the central shaft of yoke frame respectively, and wherein the horizontal end face in the right side of two extension devices is concordant with the right side of yoke frame; Described boosting mechanism, comprise two straight shafts, the left end of these two straight shafts welds respectively half disc cam, two halves disc cam is connected on two supporting legs by bearing pin respectively, two halves disc cam and above-mentioned two blocks form respectively cam mechanism, are welded to connect part and the afterburning handle of welding in the middle of connector between two straight shafts.
The beneficial effects of the utility model: use this to add sealed packing specific purpose tool, single pump single has added packing time shorten 30 minutes on year-on-year basis, extended the service life of water injection pump packing simultaneously, through test, life cycle has on average extended 5-7 days, greatly alleviate water injecting pump operative employee's labour intensity, saved Master Cost simultaneously.This specific purpose tool also has feature easy to use, price is low, is suitable for applying.
Accompanying drawing explanation
Fig. 1 is the front view that the utility model plunger type water pump adds sealed packing specific purpose tool.
Fig. 2 is the left side view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
By Fig. 1 in conjunction with shown in Fig. 2, Fig. 3: a kind of plunger type water pump adds sealed packing specific purpose tool, comprise: holder 1, yoke frame 6, tension spring 2 and boosting mechanism, wherein, the main body of holder 1 and yoke frame 6 is semi-circular tube, along the two straight flanges welded rails 10 respectively of holder semi-circular tube, yoke frame 6 is inserted into that holder 1 is interior to be moved along track 10, between holder 1 and yoke frame 6, be also fixedly connected with tension spring 2, the right flank that welds 3, two blocks 3 of two blocks on holder 1 is all concordant with the right side of holder 1; On described yoke frame 6, weld the central shaft that two supporting legs 4 and two extension device 7, two supporting legs 4 and two extension devices 7 are symmetrical in yoke frame 6 respectively, wherein the horizontal end face in the right side of two extension devices 7 is concordant with the right side of yoke frame 6; Described boosting mechanism, comprise two straight shafts 8, the left end of these two straight shafts 8 welds respectively half disc cam 5, two halves disc cam 5 is connected on two supporting legs 4 by bearing pin respectively, two halves disc cam 5 forms respectively cam mechanism with above-mentioned two blocks 3, is welded to connect part and the afterburning handle 9 of welding in the middle of connector between two straight shafts 8.
During use, plunger type water pump is added to sealed packing specific purpose tool to be arranged in packing gland, then packing is put into stuffing-box, firmly pull afterburning handle, under the effect of cam mechanism, yoke frame along track move right to packing end contact, will act on force transmission on afterburning handle to packing, finally each packing is by the parallel stuffing-box of compressing into successively.Because be provided with extension device on yoke frame, the contact area of yoke frame and packing end face strengthens, so the stressed of packing end face is uniformly, also just makes the sealing property of packing obtain maximum protection.
