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 for pumping iron ore concentrate slurry and piston diaphragm pump.

Background technique

Piston diaphragm pump is the visual plant of long-distance slurry Cemented filling, especially relates to high-pressure slurry Cemented filling.

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

Fix slide block 3 under normal circumstances to dismantle back piston bar 1 and drive connecting rod 2 to get final product delamination.But in actual motion, because piston rod 1 is in high load, high pressure (such as: 200 MPas) state for a long time with driving connecting rod 2, easily cause piston rod 1 and driving connecting rod 2 in conjunction with tension, after fixing slide block 3 is dismantled, piston rod 1 and driving connecting rod 2 still separation difficulty.

The maintenance of piston diaphragm pump such as piston pressure ring, guide ring, seal ring etc., maintenance all require that piston rod 1 is separated can operates with driving connecting rod 2.Based on piston diaphragm pump piston cylinder narrow space, large-scale maintenance separating tool cannot be suitable for, therefore the device being applicable to piston diaphragm sucker rod 1 according to actual design and driving connecting rod 2 to be separated.

Summary of the invention

The present invention devises a kind of piston diaphragm sucker rod segregating unit and piston diaphragm pump, to be piston rod be in high load, high pressure conditions and cause being difficult in conjunction with tension the difficult problem that is separated with driving connecting rod to its technical problem solved for a long time, and also cannot be applicable to large-scale service kit because piston-cylinder volume is little and be separated.

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

A kind of piston diaphragm sucker rod segregating unit, when piston rod (1) is separated with driving connecting rod (2), piston rod (1) to be connected with screw rod (8) by piston diaphragm sucker rod segregating unit and to form a traction fixed end, drives connecting rod (2) one end to be subject to tractive force effect and forms a 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 a collar and is socketed in the annular groove (9) of piston rod (1), anchor ear (4) two ends are connected with a retaining ring (6) respectively by a pull bar (5), and it is upper and undertaken spacingly can not leaving screw rod (8) by the nut on screw rod (8) that two retaining rings (6) are socketed in two not threaded (8) respectively.

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

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

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

Further, two pull bars (6) with diameter for be arranged on described anchor ear (4) circumferentially axisymmetrically.

Further, the tractive force driving connecting rod (2) one end to be 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), fixing slide block (3) also correspondence is provided with projection, fixing slide block (3) is by piston rod (1) and drive connecting rod (2) to be fixed, and it is characterized in that: also comprise piston diaphragm sucker rod segregating unit.

Further, fixing slide block (3) is combined and is fixed by bolt for upper and lower two pieces.

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

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

(2) the present invention due to two connecting ends of piston diaphragm sucker rod segregating unit be all utilize existing parts in diaphragm pump: screw rod and annular groove, thus only existing parts need be utilized when arranging segregating unit, without the need to carrying out any substantial destructiveness transformation to diaphragm pump, thus structure is more simple, and user cost is also lower.

(3) inventive piston diaphragm pump piston bar segregating unit can adjust the girth of anchor ear within the specific limits owing to regulating movable button, makes the adjustable of anchor ear girth, has easy-to-operat and is suitable for the advantage of different-diameter type piston rod.

(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.
