Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As Figure 1-4, the plunger pump of granule medium of carrying of the present invention comprises power end and fluid end, and described power end comprises drive motor or diesel engine, bent axle and the crosshead being connected with described transmission of crankshaft, described power end similarly to the prior art, no longer launches to describe at this.Described fluid end comprises the intake chamber 2 that inside is formed with the plunger compartment 1 of two plunger cavities, is fixedly connected on described outside, plunger compartment (being the distally of relative power end) and is communicated with described plunger cavity, described intake chamber also with through liquid entering hole 4 is communicated with constantly atmospheric dielectric is introduced with liquid inlet pipe simultaneously, reciprocally swingingly be arranged in intake chamber and discharge opeing bend pipe 20 that lower end mouth can be alternatively communicated with described plunger cavity, described discharge opeing bend pipe passes intake chamber and is communicated with pressure duct after the rotary seal with intake chamber's outer panel.
Described plunger compartment is a housing structure, it is arranged on fluid end chest portion and divides outside (being the distally of relative power end), its two of interior formation has can allow respectively the reciprocating plunger cavity 12 of plunger 11, described plunger cavity is through hole up/down perforation and that operation plunger slides up and down, through hole top is communicated with intake chamber, described plunger base is in transmission connection through connecting rod and crosshead, and the bent axle being driven drives plunger reciprocating action in plunger cavity to realize imbibition and discharge opeing is moved.Wherein, for realizing the transmission of granule medium, the top board of described plunger compartment (is the distally of relative power end, also can be with reference to Fig. 3, be the epipleural of plunger compartment) on be fixedly installed hard, wear-resistant plate 13, on described hard, wear-resistant plate, offer the through hole corresponding with described plunger cavity, same, the inner port of described discharge opeing bend pipe also adopts hard material to make or connect wear-resistant sleeve that a hard metal makes to improve its working life and sealing effect.Hard, wear-resistant plate close contact described in the inner port of described discharge opeing bend pipe and its swing relatively, the swing of described discharge opeing bend pipe has two stations, corresponding with the through hole on two hard, wear-resistant plates respectively.
Plunger pump of the present invention is when work, when one of them plunger is return, another ejects, discharge opeing bend pipe described in when plunger starts to eject is will be driven corresponding by its inner port through hole corresponding with this plunger, plunger ejects compression internal liquid and highly pressurised liquid can be drained into pressure duct via discharge opeing bend pipe so, finally reach using end, simultaneously, because another through hole is in open state, in plunger is return Shi Qijiucong intake chamber, imbitition enters plunger cavity, when it returns to minimum point and starts back to eject, now the inner port of discharge opeing bend pipe can be close to hard, wear-resistant plate and arrive through hole that this plunger is corresponding and realize liquid and derive, in moving process, discharge opeing bend pipe and hard, wear-resistant plate close contact do not have medium leakage, can keep the high pressure in discharge opeing bend pipe, and when aligning in process with through hole, close contact and shearing force between via openings and discharge opeing bend pipe inner port can arrange all impurity, even the particle at edge mouth place can be shredded to guarantee the sealing effect of contacting point.
Specifically, for driving described discharge opeing bend pipe to swing, on the top board of described plunger compartment, be rotatably provided with swing axis 22, on described discharge opeing bend pipe, be provided with integratedly can fixed cover be located on described swing axis and with the sleeve 21 of its interlock, described discharge opeing bend pipe can be driven along described swing axis reciprocally swinging so that the inner port of described discharge opeing bend pipe is communicated with the through hole of described hard, wear-resistant plate by swing axis, be communicated with plunger cavity, wherein, the driving mechanism of described discharge opeing bend pipe comprises that center and swing axis extend the vertical swing arm being fixedly connected with 30 of the outside tail end in plunger compartment, two chains 31 that are connected with described swing arm end respectively, two two rotating blocks 33 that can be rotatably set in respectively pump housing both sides, and the push rod 34 that can slide along plunger motion direction, described chain is fixedly connected with the rotating block of respective side after upper saw pulley 32, described push rod front end can collide and drive its rotation with described rotating block, wherein, the shape design of rotating block arbitrarily pulling chain to be as the criterion when swinging.When rotating, rotating block makes to pull swinging arm by chain, swing arm can drive swing axis to rotate, then the inner port that realizes discharge opeing bend pipe is pulled to the through hole of this side, the end of described push rod is provided with jacking block, when described jacking block can move upward at the plunger of place side, collides so that the lower end mouth of discharge opeing bend pipe is communicated with this plunger accent with crosshead or bent axle.
Adopt the cooperation of jacking block, push rod, rotating block and chain and swing arm, the action of discharge opeing bend pipe and crosshead or bent axle are connected, can realize synchronizeing of discharge opeing bend pipe and plunger action, the while has also been simplified holistic cost, makes overall structure more compact.
In above-described embodiment, be to take two plunger cavities to carry out exemplary illustrated as example, for three or three above plunger cavities, can realize object of the present invention equally, only need corresponding change driving mechanism of the present invention, do not repeat them here.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
