New closed refrigeration compressor of rotary

Degree of Freedom, as: F = 3H a 2-Pn = 1 (1) style (1) From the perspective of mechanism that the new hinged vane rotary compressor body is a definite body, so its movement is the only determined. In other words, it does not interfere with the phenomena and the occurrence of body movement uncertain phenomenon. 2.2 Calculation and analysis of movement Vo1.29. No. 6.200lFLUIDMACHINERY shown in Figure 2, set the rotor axis 0. Q axis rotating cylinder with eccentric distance e, Sly P axis of the rotating cylinder distance q, the slider and the rotor axis of P O distance, the rotation of the rotor rotating inside the cylinder radius r pore radius R, rotor angular velocity, angular velocity of the cylinder rotation. .

I (1) (6) Clearly,[link widoczny dla zalogowanych], when the switch away from the rotor axis of the column from the farthest point away from the rotor axis of movement to the nearest point (where O ≤ a ≤), isolated from leaves of two relative to the funny position of just over the limit,[link widoczny dla zalogowanych], Lu can be obtained in the area relative to leaf segments isolated from the average transfer speed of Guangxi funny i is: aa: = (+ I: = a 2ewhr (7) The negative sign indicates the slider to the axis of P ol movement. Similarly rectifiable was the interval with the rotor rotating cylinder in contact with the relative speed at the i is: =. (z-M) = (ecorCO ~ ~ t.. === women = 1 ( Cool

because the small value of eccentricity e Therefore, from (7) and ( Cool

shows that, relative to the isolated leaves turn and the rotation speed of column slide cylinder in contact with the rotor speed is at a relatively very small, this area will help reduce their friction between, on the other hand also increases the lubrication between them difficult, because the movement is too small relative velocity of the lubricant film is more difficult to establish deputy. 3 Conclusions (1) This paper introduces a new gate closed rotary motion compression institutions were transferred flat slider bar mechanism is a movement of 1 degree of freedom to determine body; (2) Since the adoption of fixed axis rotation of the technology, so the moving parts of the centrifugal force generated by smaller, so the compressor vibration and noise is also small; also significantly reduced the rotor and the rotating cylinder cyberspace, and the isolation between the leaf cover and seal the side of the relative speed, helps to reduce the friction loss between them; (3) Compressor major zero Most of the cylindrical main component parts, no particular structure of parts, that is, technology is simple in structure and manufacturing cost advantages.
