Abstract
A plunger mounting tool for a reciprocating plunger pump comprises a stress application rod, a push rod and a pipe casing, wherein external threads capable of being matched and fixed with threads at a suction inlet of a hydraulic cylinder are formed on the circumferential outer surface of the pipe casing, and an axial thread hole is formed in the rear end of the pipe casing; the push rod can extend into the thread hole, and external threads matched with the thread hole are formed in the circumferential direction of the push rod; and the rear end of the push rod is connected with the stress application rod. The plunger mounting tool for the reciprocating plunger pump is simple and reasonable in product structure, easy to mount and carry and safe, convenient and labor-saving to operate and use, and risks caused by common hammering of a plunger are avoided; and besides, through the plunger mounting tool, the plunger can be rapidly and reliably mounted in place in a labor-saving manner, so that the assembly efficiency is improved, the efficiency of field replacement of the plunger is improved, the replacement time is saved, and plunger parts are prevented from being damaged.
Description
Technical field
Patent of the present invention belongs to installation, the reparation field of reciprocating pump, especially a kind of specific purpose tool of plunger being applicable to install new plunger or more renew.
Background technology
In the use procedure of the reciprocating pumps such as reinforcing oil well pump, fracturing pump, plunger wear is very ordinary, changing plunger is common and loaded down with trivial details work, the method of installing plunger is with cork or rubber hammer hammering substantially, iron hammer hammering is even used at some scenes, chip can be caused to splash, damage the accident of plunger or miscellaneous part, and installation is wasted time and energy, operation is inconvenience extremely.
Summary of the invention
Object of the present invention is exactly for prior art Problems existing, provides that a kind of structure is simple, easy to operate, reliable and stable, plunger erecting tools safely and efficiently.
Technical scheme of the present invention is: comprise boosting-rod, push rod and pipe box, and the circumferential exterior surface of described pipe box is provided with external screw thread that can be fixing with fluid cylinder suction inlet end threaded engagement, and the rear end of described pipe box is provided with axial screwed hole; Described push rod can stretch in described screwed hole and push rod circumference is provided with the external screw thread coordinated with described screwed hole; The rear end of described push rod connects boosting-rod.
Such scheme can more preferably:
Described boosting-rod is connected with push rod is vertical.
Described boosting-rod is flexibly connected with push rod by threaded engagement.
Product structure advantages of simple of the present invention, easy installation is carried, operation use safety, convenience, laborsaving, avoid the risk that common hammering plunger causes, by this plunger erecting tools, can fast, plunger is in place by reliable, labour-saving, thus improve efficiency of assembling, and improve the efficiency of spot replace plunger, save replacing construction, avoid damaging plunger part.

Fig. 1 is structural representation of the present invention;
Fig. 2 is using state schematic diagram of the present invention;
In figure: 1, boosting-rod, 2, push rod, 3, pipe box, 4, plunger, 5, packing, 6, fluid cylinder.
Detailed description of the invention
See Fig. 1, a kind of plunger erecting tools for reciprocating pump, comprise boosting-rod 1, push rod 2 and pipe box 3, concrete connected mode is: the circumferential exterior surface of pipe box 3 is provided with external screw thread (external screw thread can be fixed with fluid cylinder 6 suction inlet end threaded engagement), and the rear end of pipe box 3 is provided with axial screwed hole; Push rod 2 can stretch in screwed hole and push rod 2 circumference is provided with the external screw thread coordinated with screwed hole; The rear end of push rod 2 is flexibly connected perpendicular boosting-rod 1 by threaded engagement.
Plunger 4, see Fig. 2, penetrates (in figure, plunger 4 microcephaly is front, penetrates plunger from right to left) by use procedure from suction inlet cylinder head bore, and microcephaly, front, when plunger 4 microcephaly encounters packing 5, because packing 5 holds plunger tightly, is difficult to advance; Pipe box 3 in installation piston tool is on fluid cylinder 6, and the front end of pipe box 3 is threaded, identical with the suction inlet gland screw thread of fluid cylinder 6, pipe box 3 can be threaded is screwed on fluid cylinder 6, pipe box 3 endoporus is slightly larger than plunger 4 size, and plunger 4 enters in pipe box 3, and pipe box 3 can support plunger 4; The rear end of pipe box 3 is threaded, and push rod 2 is screwed in by the screwed hole of pipe box 3 rear end, and plunger 4 is withstood in push rod 2 front end, boosting-rod 1 is installed on push rod 2, rotates boosting-rod 1, plunger 4 can be promoted forward by the screw thread of push rod 2, until plunger 4 microcephaly exposes packing nut 7, plunger is in place.
