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 1-3, the flat vertical high-pressure plunger pump that revolves of the present invention, comprise power end and fluid end, described power end comprises with lower pump body 1 and is arranged on plunger driving device in the lower pump body, described plunger driving device comprises upper bearing (metal) plate 30, the main shaft 10 that is rotatably connected with described upper bearing (metal) plate 30 and can be in transmission connection with motor and intermediate transmission dish 13 that is fixedly connected with main shaft and two and main shaft keep the side drive plates 14 that are in transmission connection, be provided with regularly respectively drive link 15 on described intermediate transmission dish and the side drive plate, the major part axle of described drive link and connecting rod 16 is rotatably connected, the plunger 21 that described fluid end comprises the upper pump casing 2 that is fixedly connected with lower pump body 1 and is arranged in the upper pump casing and can be in transmission connection with connecting rod 16.
Specifically, described two side drive plates 14 be fixedly connected on respectively driven shaft 17 two ends from cylindrical gears, this driven shaft center and upper bearing (metal) plate are rotatably connected, be about to side driven disc 14 and from cylindrical gears 19 coaxial separation upper bearing (metal) plate 30 both sides that arrange, simultaneously two are connected with a joggle with the main cylindrical gears 11 that is arranged on the main shaft from cylindrical gears simultaneously, when main shaft 10 driven rotation, main cylindrical gears 12 and intermediate transmission dish 13 rotate thereupon, simultaneously two from cylindrical gears 19 because rotate with being connected with a joggle of main cylindrical gears 11, then two side drive plates 14 rotate, and are main, the rotation of side drive plate is drivening rod final the moving up and down of plunger of realizing that move up and down.
Wherein, preferably, described main transmission dish is identical with side drive plate structure, and it comprises disk 110 and the lug along disk diameter to outwardly formation 120 that center and upper bearing (metal) plate 30 are rotatably connected, and described drive link 15 vertically is arranged on the lug.Simultaneously be formed with the drive plate that the arc groove corresponding with described lug lug when avoiding rotating is adjacent at disk and interfere, drive link is arranged on the lug prejudicially, increased its turning radius, improved plunger stroke.
To sum up, the present invention is changed to the split type drive mechanism of three drive plates with bent axle, and this structure has compact structure, is easy to processing, and the cost cost is low, is convenient to assembling and maintenance and debugging.Its force-bearing situation can be reduced to single simply supported beam that supports, Rigidity and strength is better, in the identical situation of physical dimension, can bear larger plunger force, the distance in the axle center by regulating drive plate axle center and pitman shaft place, direct pilot plunger stroke, simultaneously because the relative position between each drive plate, determined by the cylindrical gears on the main shaft and key, when the different flow of needs, in the situation that does not change plunger, change the drive plate of different size and can realize that flow changes, a nearlyer step ground, the advantage of this mechanism is to change arbitrarily the distance in the axle center at the drive plate axle center of one of them drive plate and pitman shaft place, in addition two drive plates are unaffected, even three plungers, reach the different jig frequency of three plungers with different speed output to satisfy particular demands.
Further, described main shaft outer end is fixedly installed from arc bevel gear, simultaneously vertically be provided with driving shaft 40 at described lower pump body and described main shaft, described active axle head and main shaft opposite end are fixedly installed and the described main arc bevel gear that is connected with a joggle from arc bevel gear.Adopt the arc bevel gear transmission, this drive mechanism has transmission stabilization of speed, compact structure, noise is little, cost is low, is convenient to install.
Further, described connecting rod and plunger are in transmission connection through crosshead 24, and crosshead to-and-fro motion in the crosshead housing is converted into the linear motion of crosshead with rotatablely moving of drive plate, and convert thus the linear motion of plunger to.Simultaneously, because should invention adopt vertical structure, this structure is so that the crosshead centring property is good, and therefore eccentric wear has not improved the life-span of plunger and sealing greatly yet, thereby has prolonged life cycle and the life-span of easily damaged parts.
As mentioned above, the present invention adopts the lower pump body bolt fastening structure, is fixedly installed dismountable side plate at described lower pump body rear side and top simultaneously, and both sides are fixedly installed dismountable side plate before and after described upper pump casing.Adopt split-type structural and design side plate, so that maintenance becomes simple, do not need the complete machine dismounting crucial easily worn part can be changed, greatly reduce maintenance cost.
When work, because motor is connected with shaft joint with driving shaft, the rotation of motor has driven the rotation of driving shaft, and the rotation of driving shaft has driven the rotation of main shaft by the master and slave arc bevel gear of engagement.Simultaneously the main cylindrical gears on the main shaft drive synchronously both sides from the synchronized rotation of cylindrical gears.Final realize the main transmission dish and from the synchronous rotation of drive plate, drive link then drivening rod swings.Because connecting rod links to each other with crosshead, crosshead links to each other with pull bar again, so the swing of connecting rod passes to sliding up and down of crosshead, crosshead slided up and down and passed to sliding up and down of pull bar.Pull bar links to each other with plunger, pull bar slide up and down the to-and-fro motion that has driven plunger.The to-and-fro motion of plunger has realized the synchronization motion of the Push And Release of liquid feed valve and liquid discharging valve, thereby has realized whole actions of pump.
Of the present invention putting down revolved vertical high-pressure water pump, has structure advanced person, little, lightweight, the efficient advantages of higher of volume.Can be used for the liquid that is similar to water carrying water, emulsified liquid and do not contain graininess.Be applicable to the industries such as oil, chemical industry, food, shipbuilding, building, electric power, coal mining, municipal administration, communications and transportation, cleaning unit.This high-pressure water pump need to be specially adapted to the mobile occasion of using because its volume is little, lightweight simultaneously, the desirable power plant of high-pressure water shot flow device, simultaneously liquid feed valve and liquid discharging valve are done suitable improvement, the flat liquid that vertical high-pressure water pump can also have for delivery of mud, cement slurry etc. certain viscosity that revolves of the present invention.
The two ends of this pump add valve group and control system simultaneously, can adjust the working pressure of whole system, can guarantee that again system is no more than rated pressure.Safe and reliable, self-organizing system, extremely easy to use.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle 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.
