Abstract
A kind of plunger assembling relating to plunger displacement pump assembly tool heads into device, its support tube is on push rod, head mechanism is in the front end of push rod, the top of its head mechanism is connected in pressure cap front end, taper roll bearing is had between pressure cap rear end and push rod, have pad between push rod and taper roll bearing, its pad, pressure cap, taper roll bearing, push rod are connected by screw rod.During use, after plunger being loaded plunger pump head intracoelomic cavity, the top of head mechanism is contacted with the taper hole of plunger and locates, rotate push rod and make piston advances forward by locating after packing.The utility model improves service life and the operating efficiency of plunger and packing, reduces labour intensity.
Description
Technical field
The utility model relates to plunger displacement pump assembly tool.
Background technology
Plunger displacement pump is the critical component in reinforcing oil well fracturing unit.Plunger is one of plunger displacement pump major part, and it is the common tool used in plunger assembling process that plunger assembling heads into device.The plunger assembling that current oil field uses heads into device in use, plunger is filled in pump head body inner chamber packing hole, then push rod front end sphere plunger assembling being headed into device contacts with plunger end surface taper hole, and push rod promotes plunger advancement by the thread helix transmission precession between support tube and puts in place to packing hole.The feature that this plunger assembling heads into device is that structure is simple, but there is following shortcoming: (1) plunger is in the process headed into, plunger front-end-cone hole surface and the sphere phase mutual friction of push rod front end, easy damage plunger front-end-cone hole surface, simultaneously push rod front end sphere also easily excessive wear cause push rod to be scrapped; (2) plunger is being headed in process, and between push rod front end sphere and plunger front-end-cone hole surface, frictional resistance is comparatively large, comparatively requires great effort during use; (3) plunger is being headed in process, and plunger is sagging due to deadweight, and plunger and packing axially bored line disalignment, easily cause eccentric wear to damage to packing, packing flange even can be caused to cause it scrap time serious.
Summary of the invention
The purpose of this utility model is to provide a kind of plunger to assemble and heads into device, and it is after a head mechanism has been set up in a kind of front end at push rod, effectively can protect plunger and packing and the device that can reduce labor intensity.
The technical solution of the utility model realizes as follows:
The utility model comprises support tube, push rod, head mechanism, and support tube is connected on push rod, and head mechanism is connected to the front end of push rod,
Head mechanism comprises pad, taper roll bearing, screw rod, pressure cap, top, top is in the front end of pressure cap, and be threaded connection integrally, taper roll bearing is had between the rear end of pressure cap and push rod, have a pad between push rod and taper roll bearing, pad, pressure cap, taper roll bearing, push rod are connected by screw rod.
The utility model has the advantages that:
1, the utility model is fitted due to the pressure cap end face and plunger end face heading into device, stressedly can play the effect of plunger auto-strengthening, decreasing plunger is being caused eccentric wear to damage by the process that heads into packing, improve the service life of plunger and packing, and improve the assembly quality of plunger packing;
2, the motion between plunger and push rod is taper roll bearing rotary motion by the utility model, decreases frictional resistance, alleviates labour intensity, improves operating efficiency;
3, top of the present utility model and pressure cap are as a whole all the time and do not have Relative friction to move between plunger, and available protecting plunger end surface taper hole, decreases the wearing and tearing of instrument simultaneously, extend the service life of instrument.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the Ι place enlarged drawing of Fig. 1;
Fig. 3 is the utility model assembling plunger figure.
Detailed description of the invention
See accompanying drawing embodiment, the utility model is described in further detail.
In Fig. 1: support tube 1 is threaded connection on push rod 2, the front end of push rod 2 is connected to a head mechanism 11, and push rod 2 rear end through hole is used for interting pole rotation push rod 2.
In Fig. 2: head into mechanism 11 and be made up of pad 3, taper roll bearing 4, screw rod 5, pressure cap 6, top 7, top 7 is in pressure cap 6 front end, by screw thread, top 7 is connected in aggregates with pressure cap 6, taper roll bearing 4 is installed between pressure cap 6 and push rod 2, inner ring and the push rod 2 of its taper roll bearing 4 adopt tight fit, its outer ring and pressure cap 6 also adopt tight fit, and pad 3 is housed between push rod 2 and taper roll bearing.Pad 3 and taper roll bearing 4 inner ring are fitted, play taper roll bearing 4 axial location and the effect of protecting its roller, pad 3 and pressure cap 6, taper roll bearing 4 are connected by screw rod 5 with between push rod, hole on screw rod 5 optical axis and pressure cap 6 is matched in clearance, and screw rod 5 and push rod 2 are fixing by being threaded on screw rod 5.
In Fig. 3: during use, first plunger 9 is filled in the endoporus of packing 8 in pump head body 10, then the support tube 1 on the utility model is threaded fixing with pump head body 10 by it, rotate push rod 2, push rod 2 is travelled forward by the worm drive between support tube 1, the top 7 of head mechanism 11 contacts with plunger 9 front end taper hole and positions, along with push rod 2 continues to push ahead, pressure cap 6 end face and plunger 9 end face fit gradually compress stressed, and plunger 9 is travelled forward along with the movement of push rod 2, plunger 9 is seated by packing 8 endoporus.In whole assembling process; pressure cap 6 and top 7 as a whole and between plunger 9 without any relative motion; avoid the wearing and tearing that between instrument with plunger 9, phase mutual friction causes; effectively protect the taper hole surface of plunger 9 front end; decrease the wearing and tearing of instrument simultaneously, extend the service life of instrument.Relative motion between plunger 9 and push rod is the relative rotary motion of taper roll bearing 4 Internal and external cycle, decrease the frictional resistance of push rod 2, alleviate labour intensity, improve operating efficiency, pressure cap 6 end face and plunger 9 end face are fitted and stressedly can be played the self-righting effect of plunger 9, reducing plunger 9 being headed in process damages the eccentric wear that packing 8 causes, and improves the assembly quality of plunger 9 and packing 8.
