Abstract
The present invention provides a rotor pump with simple structure and high efficiency, and its unique sealing structure ensure that said pump has no leakage at low rotating speed.
Description
Field under the present invention is a mechanical field.
The present invention introduces the notion of dynamic thinking, utilizes hydromechanical basic principle, adopts a kind of cellular sealing structure, and its purpose is to provide a kind of rotor pump of superior performance, and concrete characteristics show following several aspect:
1, a drum shape cylinder body is arranged, close suction port and exhaust port mutually arranged on each cylinder body, have one can hide between suction port and the exhaust port into active plate cylinder body and that can swing.The position that need seal on the active plate is useful on the cellular semicircle pitting of sealing.The end of active plate has axle, and axle is positioned axle sleeve or the bearing on the end cap.
2, in each drum shape cylinder body a cam follower is arranged, the maximum radius and the inboard wall of cylinder block of rotor leave certain interval; The maximum radius of rotor has sealing strip, and the radian of sealing strip is identical with the cylinder body radius, and sealing strip cloth is useful on the cellular semicircle pitting of sealing, maybe can adopt axially grooved labyrinth sealing mode.
3, seal ring and the bearing that matches with main shaft is housed on the two end cap.For improving the sealing effect of rotor end-face, under not many catabiotic prerequisite, can be furnished with the cellular sealing structure on the end cap
4, be furnished with cellular semicircle pitting on the projection of the sense of rotation of rotor, when being to turn round, purpose produces bigger air agitation or liquid disturbance, make the one side of active plate suction port form stronger negative pressure, guarantee the correct isolated location of active plate.
5, mechanical structure of the present invention is simple, and moving element cooperates rationally, and technological requirement is low, and technology is promoted and made all very favourable.
6, sealing means of the present invention is very reliable, when rotating speed reaches per minute 500 commentaries on classics, can accomplish to have no to leak.
For realizing above-mentioned purpose of the present invention, concrete technological scheme is as follows:
1, mutually suction port and exhaust port are arranged nearby on the drum shape cylinder, settle the separation plate that to swing between suction port and the exhaust port, suction port and exhaust port are separated under any motion state; Separating needs the position face of sealing that cellular semicircle pitting is arranged on the plate, be used to guarantee good sealing.
2, in the drum shape cylinder cam follower is arranged, the bump of rotor maximum radius axially has a sealing strip, and the radian of sealing strip is identical with the inboard wall of cylinder block radian, between keep slidably gap, looking working ability between its gap can have big worker poor; Be furnished with cellular semicircle pitting on the rotor end-face, the vortex with the gas that forms in the cellular sealing structure or liquid during running leaks in order to intercept.
3, the present invention is made up of drum shape cylinder body, axle, cam follower, separation plate and front and rear cover.The one side that end cap is relative with rotor end-face also can be furnished with the cellular sealing structure, in order to improve the air-proof condition of end face
With characteristics and technological scheme, provide position view of the present invention and structure principle chart according to last.
Fig. 1 is a basic block diagram of the present invention.
Fig. 2 is a position view of the present invention
The name of each several part is called among the figure:
1, cylinder body;
2, rotor;
3, separate plate;
4, main shaft;
5, separate the plate axle;
6, key;
7, front and rear cover;
8, bearing or axle sleeve;
9, suction port;
10, exhaust port.
Below in conjunction with accompanying drawing, provide most preferred embodiment of the present invention.
Be most preferred embodiment of the present invention as shown in Figure 1 and Figure 2.Its structure division is familiar with by Fig. 1, Fig. 2 description of drawings.Following is workflow explanation of the present invention.
According to the sense of rotation shown in the figure, in rotor when running,, will be separated plate 3 simultaneously and be adsorbed on rotor 2 cambered surfaces in gas or the liquid suction cylinder with suction port 9; By rotor 2 bumps gas or liquid are discharged by exhaust port 10, the rotor bump will be separated plate 3 jack-up in the time of discharge, cause negative pressure will separate plate when rotor streaks again and be adsorbed in the rotor cambered surface, reach the effect and the sealing of separation.
Claims (4)
1, the present invention is made up of drum shape cylinder body, axle, cam follower, separation plate and these critical pieces of front and rear cover, rotor is in the rotation down of being tended to act, to separate plate when sucking fluid and adsorb sub-rotor cambered surface by suction port, reach buffer action, discharge fluid by exhaust port under the state of rotation.
2, according to claim 1, all hermetic units of the present invention all are furnished with cellular semicircle pitting, and the fluid in the pitting forms vortex at a high speed under pressure or under the drive of moving element, in order to realize sealing
3, according to claim 1, guarantee reasonable clearance between rotor bump of the present invention and the cylinder body, sealing strip can be furnished with cellular sealing structure or labyrinth seal structure.
4, according to claim 1, the separation plate among the present invention is a device of putting that is subjected to the rotor motion domination.
