Background technique
Magnetic drive pump pump intake liquid medium in operation process reduces suddenly and even disappears, cause Magnetic Drive Pump Sliding Bearing generation dry friction situation, dry friction makes the wearing and tearing of sliding bearing and axle sleeve strengthen to accelerate, but also localized hyperthermia, the undergoes rapid expansion of bearing and axle sleeve can be caused, if be now subject to the rapid cooling of medium, rapid desufflation wanted by bearing and axle sleeve, making pressure local distribution inequality finally make bearing and axle sleeve burst because being subject to thermal shock, causing the serious consequence such as termination of pumping, motor damages.
Magnetic drive pump load exceedes scope of design, and motor meeting overload operation, the long-time overload operation of magnetic drive pump, can damage motor, permanent magnet clutch outer corner difference also can be made excessive and internal-external magnetic steel slippage occurs during serious overload, damages magnetic drive pump.
When magnetic drive pump is in operation process, blocked between internal rotor and separation sleeve by foreign matter, electric electromechanics fails to be convened for lack of a quorum and raises rapidly, and damage motor, therefore separation sleeve also can be damaged.
Summary of the invention
The object of this invention is to provide a kind of magnetic drive pump dry friction, overload, coupling slippage, rotor card mill protective gear, can realize magnetic drive pump dry friction, overload, permanent magnet clutch slippage, pump internal rotor card, the protection of mill situation.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises separation sleeve, is distributed in the interior magnet steel ring of separation sleeve both sides and outer steel ring, it is characterized in that described protective gear is made up of intelligent signal processing circuit board and more than one permanent magnet clutch outer corner difference sensor; Each permanent magnet clutch outer corner difference sensor by between separation sleeve and outer steel ring, two interval angles being fixed on separation sleeve outer surface and separation sleeve parallel to an axis are that the detection wire of θ forms, θ be 360 degree with the ratio of outer steel number, detect the wire wire axially vertical with separation sleeve to be connected along separation sleeve outer surface, each permanent magnet clutch outer corner difference sensor is in series and angle of being separated by is the odd-multiple of θ, and two line ends that are in series are signal output; Described intelligent signal processing circuit board is made up of sensor signal inlet opening, off signal delivery outlet, signal processing circuit and embedded scm intelligent system, the output signal of permanent magnet clutch outer corner difference sensor is by sensor signal inlet opening access signal processing circuit, after carrying out amplification and shaping, send into embedded scm intelligent system, by carrying out dutycycle calculating and intellectual analysis to this signal, judge magnetic drive pump operation conditions, send off signal by off signal delivery outlet.
The said structure that the present invention adopts, can protect magnetic drive pump dry friction, overload, permanent magnet clutch slippage, pump internal rotor card, mill situation, prevent pump and motor damage, thus increase the service life.
