Abstract
The invention discloses a mechanical seal transmission device applied to high-pressure working conditions, comprising a threaded pin (1), a transmission mechanism (2), a first O-shaped ring (3), a second O-shaped ring (4), a rotating ring (5), a snap ring (6), a stationary ring (7), a spring (8), a third O-shaped ring (9) and a shaft sleeve (10), wherein the transmission mechanism (2) is connected with the shaft sleeve (10) through the threaded pin (1); the first O-shaped ring (3) and the second O-shaped ring (4) are arranged on the shaft sleeve (10); the rotating ring (5) is connected with the shaft sleeve (10); the stationary ring (7) is connected with the rotating ring (5); the snap ring (6) is arranged in a snap ring groove of the transmission mechanism (2); and the spring (8) and the third O-shaped ring (9) are connected on the stationary ring (7). The mechanical seal transmission device applied to the high-pressure working conditions, disclosed by the invention, has the advantages that the axial stress and the radial stress of the transmission mechanism in high-pressure environments are balanced to ensure that the deformation does not happen under high pressure, therefore, stable and reliable transmission is carried out.
Description
Technical field
The present invention relates to a kind of mechanical seal transmission device, relate in particular to a kind of mechanical seal transmission device that is applied to the high pressure operating mode.
Background technique
Mechanical seal is that a kind of usefulness solves the device that seals between running shaft and the body; It is to be kept fitting under the cooperation of the effect of hydrodynamic pressure and compensation mechanism elastic force (or magnetic force) and auxiliary seal perpendicular to the end face of spin axis and slide relative and constitute the device that prevents escape of liquid by at least one pair of, is usually used in rotary type fluid machines such as pump, compressor, reaction stirred tank.Wherein one of basic building block of mechanical seal is exactly a driving mechanism, mainly plays transmitting torque.In rotary machine sealing, many spring structures are used mode transmissions such as dome pit, pin, shift fork always, and single spring structure is often with the gearing of having held concurrently of the doubling-up of spring self or buckle structure; In state type mechanical seal, rotating ring Chang Yijian, pin come transmission.Along with present equipment working condition parameter constantly improves especially under high-pressure situations; Existing driving mechanism is easy to deformation failure in transmission process; Influence whole mechanical seal device, have driving mechanism existing transmission problem in hyperbaric environment now so Here it is.
Summary of the invention
The purpose of this invention is to provide and a kind ofly under high pressure can not produce distortion, the mechanical seal transmission device that is applied to the high pressure operating mode that transmission is reliable and stable.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of mechanical seal transmission device that is applied to the high pressure operating mode; Comprise threaded (1), driving mechanism (2), O shape circle (3), the 2nd O shape circle (4), rotating ring (5), snap ring (6), stationary ring (7), spring (8), the 3rd O shape circle (9) and axle sleeve (10); Said driving mechanism (2) is connected with axle sleeve (10) through threaded (1); Said O shape circle (3) and the 2nd O shape circle (4) are installed on the axle sleeve (10); Said rotating ring (5) is connected with axle sleeve (10); Said stationary ring (7) is connected with rotating ring (5), and said snap ring (6) is installed in the annular groove of driving mechanism (2), and said spring (8) and the 3rd O shape circle (9) are connected on the stationary ring (7).
Said axle sleeve (10) transfers torque on the driving mechanism (2) through threaded (1).
Said driving mechanism (2) adopts Spielpassung with axle sleeve (10).
Said driving mechanism (2) transfers torque on the rotating ring (5) through dome mechanism.
A kind of mechanical seal transmission device that is applied to the high pressure operating mode of the present invention, driving mechanism be axial stressed and radial force balance in hyperbaric environment, can not be out of shape owing to high pressure produces, thereby carry out reliable and stable transmission.
