The invention discloses a rotation-type on-line viscometer which comprises a shell (15), wherein the lower part of an inner cavity of the shell (15) is provided with an isolation panel (11); the isolation panel (11) separates the inner cavity of the shell (15) into a driving chamber (4) and a measuring chamber (9) in mutual isolation; the driving chamber (4) is internally provided with a driving motor (1), a signal detecting mechanism and a signal processing circuit (16); the driving motor (1) is connected with one end of a rotary main shaft (3) through a speed reduction mechanism (2), and the other end of the rotary main shaft (3) is fixedly provided with a magnetic force conducting head (5); the measuring chamber (9) is internally provided with a viscosity detecting head (7) which is opposite to the magnetic force conducting head (5) and rotates synchronously; the magnetic force conducting head (5) is internally provided with a driving magnet (6), the polarity of which is contrary to that of a driven magnet (8) arranged in the viscosity detecting head (7); and through holes are formed in the side wall of the shell (15) at the position of the measuring chamber (9). According to the invention, static sealing is adopted, and performances are stable.
Description
technical field [0001] The invention relates to a viscometer, in particular to a rotary on-line viscometer with static sealing and stable performance. Background technique [0002] At present, the measuring mechanism of the existing rotary viscometer is directly connected with the driving mechanism, and the measuring mechanism must be in direct contact with the measured medium, while the driving mechanism generally cannot directly contact the measured medium. When used for online detection, the driving mechanism must be placed outside the process device (reactor, pipeline, etc.), and a dynamic seal should be made at the connection with the measuring mechanism. This sealing method works online and is under rotating friction for a long time. When measuring at high temperature and high pressure, its performance changes will lead to errors in the measurement results. Contents of the invention [0003] The object of the present invention is to provide a rotary on-line viscome...
