Abstract
A plunger pump reciprocating apparatus comprises a cylinder body, a plunger, an upper plate, a power shaft, and a lower plate. The upper and the lower plates are buckled with each other, eccentric holes are aligned and sleeved on the power shaft, the upper and the lower plates rotate with the power shaft, the plunger is arranged inside the cylinder body, a boss is arranged at one end of the plunger, a ring-shaped groove is arranged inside the upper and the lower plates, and the boss of the plunger is buckled by the ring-shaped grooves inside the upper and the lower plates. During operation, because the eccentric holes on the upper and the lower plates are aligned and sleeved the power shaft, when the power shaft rotates, the ring-shaped grooves inside the upper and the lower plates continuously push and pull the plunger to allow the plunger to reciprocate, so as to realized the operation of a plunger pump. The inventive apparatus replaces the crank-link mechanism on the prior plunger pump and allows the plunger to perform reciprocating movement; and is suitable for multi-cylinder plunger pumps. The plunger pump equipped with the reciprocating apparatus has the advantages of simple structure, reduced volume, convenient production, low production cost, stable operation, and low noise.
Description
One, technical field:
The present invention is the device on the plunger pump, is a kind of reciprocating apparatus of plunger pump.
Two, background technique:
The plunger of plunger pump is reciprocating, and the motor that drives plunger motion is to rotatablely move, and rotatablely moves to become to-and-fro motion and need connecting rod, therefore, present plunger pump complex structure, bulky, make difficulty, the cost of production height moves not steadily, and noise is big.
Three, summary of the invention:
The objective of the invention is to design a kind of reciprocating apparatus of plunger pump, make it simple in structure, volume is little, operates steadily.
The object of the present invention is achieved like this: be made up of cylinder body, plunger, last dish, line shaft, lower wall, on last dish, the lower wall eccentric opening is arranged, last dish, lower wall make-up, the eccentric opening alignment bosses is contained on the line shaft, last dish, lower wall rotate with line shaft, and plunger is in cylinder body, and an end of plunger has boss, in last dish, the lower wall annular groove is arranged, the boss of plunger is fastened by the annular groove in last dish, the lower wall.
Cylinder body, plunger have several, around last dish, the even circle distribution of lower wall central axis.
The eccentric hole wall of last dish, lower wall has keyway.
The invention has the beneficial effects as follows: the present invention can make plunger move reciprocatingly, and has replaced the connecting rod on the existing plunger pump, makes it simple in structure, volume reduces, and is easily manufactured, and cost of production is low, move not steadily, noise is little, is particularly useful for the multi-cylinder plunger pump.
Four, description of drawings:
Accompanying drawing 1 is the plan view of the embodiment of the invention.
Accompanying drawing 2 is plan views of lower wall 5 in the accompanying drawing 1.
Five, specific embodiment:
Below in conjunction with accompanying drawing the embodiment of the invention is described.
By cylinder body 1, plunger 2, on coil 3, line shaft 4, lower wall 5 form, on last dish 3, the lower wall 5 eccentric opening is arranged, last dish 3, lower wall 5 make-ups, the eccentric opening alignment bosses is contained on the line shaft 4, last dish 3, lower wall 5 are with line shaft 4 rotations, and plunger 2 is in cylinder body 1, and an end of plunger 2 has boss, in last dish 3, the lower wall 5 annular groove is arranged, the boss of plunger 2 is fastened by the annular groove in last dish 3, the lower wall 5.Cylinder body 1, plunger 2 have several, around last dish 3, the even circle distribution of lower wall 5 central axis.The eccentric hole wall of last dish 3, lower wall 5 has keyway 6.
During work, line shaft 4 rotations are owing to the eccentric opening alignment bosses on last dish 3, the lower wall 5 is contained on the line shaft 4, therefore, during line shaft 4 rotation, on coil 3, the annular grooves in the lower wall 5 constantly push away, stay column plug 2, make plunger 2 to-and-fro motion, realize the work of reciprocating pump.
