Abstract
The utility model discloses an efficient circulating compression pump which comprises a drive wheel and a driven wheel. Grooves are formed in the driven wheel, wherein the number of the grooves is even. Clamp bodies are arranged on the drive wheel, wherein the number of the clamp bodies is matched with the number of the grooves. A through hole is formed in the bottom of each groove. A pump chamber is formed in the through hole. A piston is arranged in the pump chamber and is matched with the pump chamber. Two pistons are connected through a rigid connecting piece, wherein the axes of the two pistons are in the same straight line. The driven wheel rotates around a fixed shaft. An air inlet and an air outlet are formed in the fixed shaft. When a clamp body is clamped with a groove, the pump chamber which corresponds to the groove is communicated with the air outlet, and another pump chamber which is on the same axis with the pump chamber is communicated with the air inlet. Due to the fact that a circular motion mode is made full use of, the efficient circulating compression pump has the advantages of being stable in operation, capable of greatly reducing shock and noise of a pump body, small in loss, high in efficiency, long in service life, and free from suction and exhaust valve pieces. Meanwhile, due to the fact that the rotating mechanical structure is adopted to carry out suction and exhaust, the efficient circulating compression pump is good in tightness and is capable of achieving a high vacuum degree.

Technical field
The utility model relates to a kind of vacuum pump, particularly a kind of high efficiency vacuum displacement pump.
Background technique
Vacuum pump is widely used in all trades and professions, and the vacuum pump kind is more has various structures, and various structures have pluses and minuses separately, and the limiting vacuum value that can reach also has very large difference.Large and the efficient low (as reciprocating piston pump, sliding vane rotary pump) of some surface friction drag, but easy to manufacture, cost is low; High but the processing difficulties (as Roots pump, screw pump) of some efficient, cost are high.Wherein the reciprocating piston type vacuum pump is the most ripe and the most reliable a kind of structural type at present, it realizes air-breathing, exhaust by cylinder, can reach higher vacuum values, reliability is high, maintenance is easy, easy to process, assembling is simple because piston has, the low significant advantage of cost, thereby the reciprocating piston type vacuum pump is still present most popular vacuum pump.
Reciprocating piston type vacuum pump forms of motion is that piston is done linear reciprocating motion in pump chamber, the spatial volume generating period that piston and pump chamber surround is changed, to reach the purpose of air inlet and exhaust.The form that mostly is to rotatablely move due to providing of current driving force provides, so for the driven plunger linear reciprocating motion, must drive reciprocating motions of the pistons by mechanisms such as bent axle, connecting rods, will make like this size of complete machine become large.The linear reciprocating motion of piston is acceleration and deceleration motion, and connecting rod is plane motion, certainly lead to so unbalanced inertial force and cause vibration and the mechanical noise of machine, and piston is easy to wearing and tearing, and the working life of vacuum pump is shorter.Eccentric swing has also increased force of sliding friction greatly in addition, thus consume more powerful, and rotating speed can not be too high, so efficient is lower.Comprehensive above-mentioned reason, how to find a kind of easy to manufacture, cost is low, efficient is high, the vacuum pump of high vacuum values, is the target that the Professional visitors tries hard to gain all the time always.
The model utility content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of noise is little, reliability is high, long service life, vacuum pump with high vacuum values.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
a kind of efficient circulation compressor pump, it comprises a driving wheel and a follower, described driving wheel is connected with a motor, described follower is provided with the even number groove, described groove radially evenly distributes along described follower, described driving wheel is provided with several engaging bodies, described engaging body distributes along the even circumferential of described driving wheel, when described engaging body engages with described groove, described driving wheel rotation can drive described follower rotation, the bottom of described groove is provided with through hole, form pump chamber in described through hole, be provided with the piston that matches with it in described pump chamber, two pistons that axis is located along the same line connect by rigid connector, described follower rotates around a stationary axle, described pump chamber is connected with described stationary axle motive sealing, described stationary axle is provided with an inlet hole and an air outlet hole, when described engaging body engages with a groove, the corresponding pump chamber of this groove is communicated with described air outlet hole, and another pump chamber that is positioned at same axis with this pump chamber is communicated with described inlet hole.
Preferably, described groove is the U-groove bevel that extends along described follower radial direction from described follower peripheral openings.
Preferably, described engaging body is a cylinder.
Preferably, be provided with cylinder block in the through hole of described channel bottom, described cylinder block inner chamber forms described pump chamber, described cylinder block both ends open.
Preferably, described follower is provided with 6 grooves.
Preferably, the number of described engaging body is corresponding with the number of described groove.
technique scheme has following beneficial effect: this vacuum pump is when work, the rotation of driven by motor driving wheel, the engaging body engages with a groove on follower after driving wheel rotates to an angle, rotation along with driving wheel, the engaging body moves inward along groove gradually, and then driven plunger inwardly moves in pump chamber, due to this moment this pump chamber be communicated with air outlet hole, so just the gas in this pump chamber can be discharged, meanwhile, can outwards move along the pump chamber at its place by another piston that rigid connector is connected with this piston, and this pump chamber is connected with inlet hole, this pump chamber can be inwardly air-breathing by inlet hole like this, by that analogy, driving wheel this vacuum pump that often rotates to an angle can be completed once air-breathing, the process of exhaust.This vacuum pump takes full advantage of the mode of circular movement, move more steady, can significantly reduce vibrations and the noise of the pump housing, loss is less, and efficient is high, long service life, and need not the intake and exhaust valve block, have this rotary machine structure of employing to carry out air-breathing, exhaust, its better tightness can realize higher degree of vacuum again.
