A kind of piston diaphragm sucker rod segregating unit and piston diaphragm pump

Technical field

The present invention relates to a kind of piston diaphragm sucker rod segregating unit and piston diaphragm pump, especially relate to a kind of piston diaphragm sucker rod segregating unit and piston diaphragm pump for pumping iron ore concentrate slurry.

Background technique

Piston diaphragm pump is the visual plant that the long-distance slurry pipeline is carried, and especially relates to the high pressure Slurry Pipeline Transportation.

As shown in Figure 1, be existing piston diaphragm sucker rod connection diagram.Piston diaphragm sucker rod 1 by fixing slide block 3 with drive connecting rod 2 and be connected, piston rod 1 is respectively equipped with annular groove with the connecting end of driving connecting rod 2, fixedly slide block 3 also correspondence be provided with projection and be connected in the annular groove.

Generally fixedly slide block 3 dismounting back piston bars 1 get final product delamination with driving connecting rod 2.But in the actual motion, since piston rod 1 with drive connecting rod 2 and be in for a long time high load, high pressure (such as 200 MPas) state, easily cause piston rod 1 and drive connecting rod 2 in conjunction with tension, fixedly after slide block 3 dismountings, piston rod 1 and driving connecting rod 2 be separation difficulty still.

The maintenance of piston diaphragm pump such as piston pressure ring, guide ring, seal ring etc., maintenance all require piston rod 1 to separate and can operate with driving connecting rod 2.Based on piston diaphragm pump piston cylinder narrow space, large-scale maintenance separating tool can't be suitable for, thus according to actual design be applicable to piston diaphragm sucker rod 1 and the device that drives connecting rod 2 and separate.

Summary of the invention

The present invention has designed a kind of piston diaphragm sucker rod segregating unit and piston diaphragm pump, the technical problem of its solution is piston rod and drive connecting rod and be in for a long time high load, high pressure conditions and cause the difficult problem that is difficult to separate in conjunction with tension, and because the piston-cylinder volume is little also can't be applicable to large-scale service kit and separate.

In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:

A kind of piston diaphragm sucker rod segregating unit, piston rod (1) with drive connecting rod (2) when separating, piston rod (1) is connected with screw rod (8) by piston diaphragm sucker rod segregating unit and forms a traction fixed end, drives connecting rod (2) one ends and is subject to tractive force effect formation one traction force side.

Further, described piston diaphragm sucker rod segregating unit comprises anchor ear (4), pull bar (5) and retaining ring (6), anchor ear (4) is in a collar and the annular groove (9) that is socketed in piston rod (1), anchor ear (4) two ends are connected with a retaining ring (6) by a pull bar (5) respectively, and two retaining rings (6) are socketed in respectively two not threaded (8) and upward and by the nut on the screw rod (8) carry out the spacing screw rod (8) that can not leave.

Further, the screw rod of described screw rod (8) for the piston cylinder of piston diaphragm pump is fixed.

Further, described anchor ear (4) is spliced by movable button (7) by two semicircle metal rings, adjusts the girth size of anchor ear (4) by regulating movable button (7) link position.

Further, the diameter of described anchor ear (4) is less than the diameter of described piston rod (1).

Further, two pull bars (6) take diameter on the circumference that is arranged on axisymmetrically described anchor ear (4).

Further, driving the tractive force that connecting rod (2) one ends are subject to adds by jiggering is real.

A kind of piston diaphragm pump, comprise piston rod (1) and drive connecting rod (2), piston rod (1) is arranged in piston cylinder, the connecting end of piston rod (1) and driving connecting rod (2) is respectively equipped with annular groove (9), fixedly slide block (3) also correspondence be provided with projection, fixedly slide block (3) is fixed piston rod (1) and driving connecting rod (2), it is characterized in that: also comprise piston diaphragm sucker rod segregating unit.

Further, fixedly slide block (3) for up and down two combine and be fixed by bolt.

This piston diaphragm sucker rod segregating unit and piston diaphragm pump are compared with the conventional piston diaphragm pump, have following beneficial effect:

(1) the present invention because by piston diaphragm sucker rod segregating unit so that piston rod and screw rod be fixed, thereby when jiggering applies tractive force, piston rod will easily separate with the driving connecting rod, and can separate quickly and efficiently piston rod and driving connecting rod in conjunction with tension, be convenient to safeguard and maintenance.

(2) the present invention is because two connecting ends of piston diaphragm sucker rod segregating unit all are to utilize existing parts in the diaphragm pump: screw rod and annular groove, thereby when being set, segregating unit only need utilize existing parts, need not diaphragm pump is carried out any substantial destructive transformation, thereby structure is simpler, and user cost is also lower.

(3) piston diaphragm sucker rod segregating unit of the present invention so that the anchor ear girth is adjustable, has advantages of easy-to-operat and applicable different-diameter type piston rod owing to regulating the girth that movable button can be adjusted anchor ear within the specific limits.

(4) the present invention becomes the novel kit that piston diaphragm pump such as piston pressure ring, guide ring, seal ring etc. are safeguarded, overhauled.
