Abstract
The invention relates to a reciprocating plunger pump, which comprises a shell, a frame, a crankshaft supported on the frame through a bearing, a connecting rod connected to the crankshaft and a driving device for driving the crankshaft, and also comprises a horizontal rod and a first cylinder barrel, a second cylinder barrel and a third cylinder barrel which are positioned on one side of the crankshaft and arranged in parallel, wherein the first cylinder barrel, the second cylinder barrel and the third cylinder barrel are respectively provided with a first plunger, a second plunger and a third plunger; one end of each of the first, second and third plungers extending out of the corresponding cylinder barrel is connected to the horizontal rod through a first connecting rod, a second connecting rod and a third connecting rod respectively; the free end of the connecting rod is connected with the middle of the horizontal rod through a spherical hinge. The plunger pump is simple in structure, a single rod simultaneously pulls the three plungers to move, and useless internal work caused by mechanism friction is avoided to the greatest extent.
Description
Technical field
The present invention relates to a kind of plunger pump, be specifically related to a kind of reciprocating plunger pump.
Background technique
Plunger pump is an important device of hydraulic system.It relies on plunger to-and-fro motion in cylinder body, makes the volume of seal operation cavity volume change to realize oil suction, force feed.The advantages such as plunger pump has that rated pressure is high, compact structure, efficiency is high and Flow-rate adjustment is convenient, are widely used in the occasion that high pressure, large flow and flow need to regulate, in hydraulic press, engineering machinery and boats and ships.
During plunger pump work, plunger is done upper and lower to-and-fro motion, and plunger upper part space (pump chamber) produces degree of vacuum, thereby completes pump oil task.Plunger pump be take a plunger as principle introduction, on a plunger pump, there are two one-way valves, and opposite direction, when moving to a direction, plunger there is negative pressure in cylinder, at this moment an one-way valve opens liquid is inhaled in cylinder, when plunger moves to another direction, another one-way valve after liquid compression is opened, the liquid being inhaled in cylinder is discharged from.This working method has just formed continuous oil supply after motion continuously.
Horizontal plunger pump is installed side by side by several plungers substantially, and the consumed work when a plurality of plungers of promotion move simultaneously between machinery is excessive.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of reciprocating plunger pump simple in structure.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of reciprocating plunger pump, comprise housing, frame, by bearing, prop up the bent axle being located in described frame, be connected to connecting rod on described bent axle and for driving the drive unit of described bent axle, also comprise transverse bar and be positioned at described bent axle one side parallel the first cylinder barrel being set up in parallel, the second cylinder barrel, the 3rd cylinder barrel, described the first cylinder barrel, the second cylinder barrel, the 3rd cylinder barrel has respectively the first plunger, the second plunger, the 3rd plunger, described the first plunger, the second plunger, head rod is passed through respectively in one end that the 3rd plunger stretches out from cylinder barrel, the second connecting rod, the 3rd connecting rod is connected on described transverse bar, described in free one end of described connecting rod, the middle part of transverse bar connects by ball pivot.
Further, it is mutually neat that described first, second, third plunger stretches out the end face of one end from described the first cylinder barrel, the second cylinder barrel, the 3rd cylinder barrel respectively, and the length of described head rod, the second connecting rod, the 3rd connecting rod is successively decreased successively.
Further, described frame is provided with the relative chute of twice, and the two ends of described transverse bar are located at respectively in the chute of described twice.
The invention has the beneficial effects as follows:
Plunger pump structure in the present invention is simple, by single bar, pulls three plunger motion simultaneously, the useless internal strength of farthest avoiding the friction of Liao Yin mechanism to cause.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, reciprocating plunger pump of the present invention is described further.
Fig. 1 is the structural representation of reciprocating plunger pump in the present invention.
