Definitions
- the invention relates to the technical field of vacuum pumps, in particular to a novel rotary vane vacuum pump.
- a vacuum pump is a device that creates, improves, and maintains a vacuum in a closed space in a variety of ways. According to the working principle, it can be divided into a water ring vacuum pump, a Roots pump, a new rotary vane vacuum pump, etc., which generally consists of a pump body, a rotor, a rotary vane, an end cover, a spring, etc., and is eccentric in the inner cavity of the pump body.
- a rotor is provided, the outer circumference of the rotor is tangent to the wall of the pump body, and two rotating vanes with springs are mounted on the rotor.
- the top end of the rotary vane When rotating, the top end of the rotary vane is kept in contact with the wall of the pump body by the centrifugal force and the tension of the spring.
- the rotation of the rotor drives the rotary vane to slide along the wall of the pump body, thereby changing the volume of the cavity separated by the rotary vane to complete the inhalation and exhaust. process.
- the rotary vanes of the body cavity of the conventional vacuum pump pump are expanded by a spring, and the spring will fail after long-term use, thereby causing damage to the vacuum pump.
- the technical problem to be solved by the invention is that in order to overcome the expansion of the rotary vanes of the vacuum pump body cavity by the spring, the spring will fail after long-term use, thereby causing damage to the vacuum pump, and providing a novel rotary vane type. Vacuum pump.
- a novel rotary vane type vacuum pump comprising a pump body, a sealing end cover and a rotor rotating piece, wherein the sealing end cover is fixedly mounted on both end faces of the pump body,
- the pump body is provided with an air suction passage and an exhaust passage communicating with the inner cavity, wherein the inner cavity of the pump body is rotatably mounted with a rotating shaft, and the outer circumference of the rotating shaft is uniformly provided with a retractable rotor rotating piece, two The ends of the rotor blades are respectively provided with a slider, and the inner wall of the pump body is provided with a slide rail in the circumferential direction, and the slider is slidably engaged in the slide rail, and the end portion of the rotor rotor blade is The inner wall of the pump is tangent.
- the two rotor blades each include a fixing plate and a sliding plate
- the fixing plate is provided with a through hole
- the through hole has a depth greater than a length of the sliding plate
- the sliding plate is slidably disposed at the In the through hole
- the end of the sliding plate is provided with the slider
- the end of the sliding plate is tangent to the inner wall of the pump.
- the rotating shaft is eccentrically disposed with the axial center of the pump body cavity, and the length of the fixing plate is equal to the shortest distance from the central axis of the rotating shaft to the inner wall of the pump body.
- the rotating shaft is driven to rotate by the motor.
- the end of the sliding plate is always tangential to the inner wall of the pump body, and the shaft of the rotating shaft and the pump body cavity
- the centering of the heart is set.
- the rotating shaft rotates, the distance from the central axis of the rotating shaft to the inner wall changes, and the depth of the sliding plate into the through hole also changes, and the sliding plate reciprocates in the through hole of the fixed plate; when the center of the rotating shaft
- the shortest distance from the axis to the inner wall of the pump is the shortest, the sliding plate completely enters the through hole, and the end of the fixed plate is tangent to the inner wall.
- the rotation of the rotor vane in the inner cavity changes the volume of the cavity separated by the rotor vane to complete the inhalation and exhaust process.
- the invention has the beneficial effects that the new rotary vane type vacuum pump of the present invention has a slider slidingly inserted into the sliding rail, and when the rotating shaft rotates, the distance from the central axis of the rotating shaft to the inner wall changes, and the sliding plate enters the passage.
- the depth of the hole also changes, and the sliding plate reciprocates in the through hole of the fixed plate, so that the end of the sliding plate is always tangent to the inner wall of the pump; this structure replaces the spring, avoiding the failure of the spring after long-term use. , causing damage to the vacuum pump.
