发明内容SUMMARY OF THE INVENTION

本发明的目的是提供一种磁力泵内磁转子偏移监控装置及使用该内磁转子偏移监控装置的磁力泵,以对转子系偏移情况进行实时监控,防止内磁转子与隔离套内壁发生摩擦,发生安全事故。The purpose of the present invention is to provide a magnetic pump internal magnetic rotor offset monitoring device and a magnetic pump using the internal magnetic rotor offset monitoring device, so as to monitor the rotor system offset in real time and prevent the internal magnetic rotor from being separated from the inner wall of the isolation sleeve. Friction occurs, safety accidents occur.

本发明磁力泵内磁转子偏移监控装置,由对称固定安装在内磁转子侧端上中心线上的第一内永磁铁和第二内永磁铁,对称固定安装在隔离套外圆面上中心线上的第一线圈和第二线圈,置于磁力泵外的变送器构成;The magnetic pump inner magnetic rotor offset monitoring device of the present invention consists of a first inner permanent magnet and a second inner permanent magnet which are symmetrically and fixedly installed on the center line on the side end of the inner magnetic rotor, and are symmetrically and fixedly installed on the center of the outer circular surface of the isolation sleeve. The first coil and the second coil on the line are composed of a transmitter placed outside the magnetic pump;

所述的第一线圈71a和第二线圈71b为扁平缠绕线圈,线圈外部由绝缘树脂包裹,采用耐高温胶粘贴固定在隔离套7外圆面上。The first coil 71a and the second coil 71b are flat wound coils, the outer parts of the coils are wrapped with insulating resin, and are pasted and fixed on the outer surface of the isolation sleeve 7 with high temperature resistant glue.

所述的第一内永磁铁和第二内永磁铁的体积、形状和磁力强度相同;所述的第一线圈和第二线圈的线圈参数相同;所述的第一线圈与第二线圈相位相反串联通过传输导线与置于磁力泵外的变送器相连,变送器进行就地显示和远传。The volume, shape and magnetic strength of the first inner permanent magnet and the second inner permanent magnet are the same; the coil parameters of the first coil and the second coil are the same; the phase of the first coil and the second coil are opposite The series connection is connected with the transmitter placed outside the magnetic pump through the transmission wire, and the transmitter performs local display and remote transmission.

本发明在内磁转子侧端上中心线上对称(即180°)固定安装第一内永磁铁和第二内永磁铁,在隔离套外圆面上中心线上对称(即180°)固定安装第一线圈和第二线圈。内磁转子转动时,所述的内磁转子上的第一内永磁铁、第二内永磁铁与所述的隔离套外圆面上的第一线圈、第二线圈在径向上对应,所述的内磁转子上的第一内永磁铁和第二内永磁铁切割所述的隔离套外圆面上的第一线圈和第二线圈,第一线圈和第二线圈分别产生感应电动势(感应电流),所述第一线圈与第二线圈相位相反串联通过传输导线与置于磁力泵外的变送器相连。In the present invention, the first inner permanent magnet and the second inner permanent magnet are fixedly installed symmetrically (ie, 180°) on the center line on the side end of the inner magnetic rotor, and are fixedly installed symmetrically (ie, 180°) on the center line on the outer circular surface of the isolation sleeve. first coil and second coil. When the inner magnet rotor rotates, the first inner permanent magnet and the second inner permanent magnet on the inner magnet rotor correspond to the first coil and the second coil on the outer circular surface of the isolation sleeve in the radial direction. The first inner permanent magnet and the second inner permanent magnet on the inner magnetic rotor cut the first coil and the second coil on the outer surface of the isolation sleeve, and the first coil and the second coil respectively generate induced electromotive force (induced current) ), the first coil and the second coil are connected in series with opposite phases to the transmitter placed outside the magnetic pump through a transmission wire.

当内磁转子没有径向偏移时,即内磁转子和其上的第一内永磁铁和第二内永磁铁与隔离套之间的间距相等时,内磁转子上的第一内永磁铁和第二内永磁铁与隔离套上的第一线圈和第二线圈之间的间距相等,第一线圈和第二线圈受第一内永磁铁和第二内永磁铁磁力线切割产生的感应电动势(感应电流)大小相同、方向相反;由于第一线圈和第二线圈相位相反串联,因此第一线圈和第二线圈相位相反串联产生的感应电动势(感应电流)互相抵消,其输出的感应电动势(感应电流)为零。When the inner magnet rotor is not radially offset, that is, when the distances between the inner magnet rotor and the first and second inner permanent magnets on the inner magnet rotor and the spacer sleeve are equal, the first inner permanent magnet on the inner magnet rotor The distance between the second inner permanent magnet and the first coil and the second coil on the isolation sleeve is equal, and the first coil and the second coil are subjected to the induced electromotive force ( Induced current) is the same in magnitude and opposite in direction; since the first coil and the second coil are connected in opposite phases, the induced electromotive force (induced current) generated by the first coil and the second coil in opposite phase and series cancels each other out, and the output induced electromotive force (induction current) cancels each other out. current) is zero.

当内磁转子发生径向偏移时,即内磁转子和其上的第一内永磁铁和第二内永磁铁与隔离套之间的间距在径向上向一侧偏移时,内磁转子上的第一内永磁铁和第二内永磁铁与隔离套上的第一线圈和第二线圈之间的间距改变,即第一内永磁铁和第二内永磁铁与第一线圈之间的距离和第一内永磁铁和第二内永磁铁与第二线圈之间的距离一大一小;由于永磁铁与线圈的距离不同,永磁铁磁力线切割线圈的强度不同,这样在第一线圈和第二线圈产的感应电动势(感应电流)大小不同,因此第一线圈和第二线圈相位相反串联产生的感应电动势(感应电流)不能互相完全抵消,输出感应电动势(感应电流)大于零;经变送器对感应电动势(感应电流)进行(滤波、放大)比对处理,从而判定内磁转子是否发生径向偏移和径向偏移量,进行就地显示和远传控制,从而对磁力泵主轴系偏移情况进行实时监控,防止内磁转子与隔离套内壁发生摩擦,发生安全事故。When the inner magnetic rotor is radially displaced, that is, when the distance between the inner magnetic rotor and the first and second inner permanent magnets on it and the spacer sleeve is displaced to one side in the radial direction, the inner magnetic rotor The distance between the first inner permanent magnet and the second inner permanent magnet on the spacer and the first coil and the second coil on the isolation sleeve is changed, that is, the distance between the first inner permanent magnet and the second inner permanent magnet and the first coil is changed. The distance and the distance between the first inner permanent magnet and the second inner permanent magnet and the second coil are larger and smaller; due to the different distances between the permanent magnet and the coil, the strength of the permanent magnet magnetic field line cutting coil is different, so that between the first coil and the coil The magnitude of the induced electromotive force (induced current) produced by the second coil is different, so the induced electromotive force (induced current) generated by the first coil and the second coil in series with opposite phases cannot completely cancel each other, and the output induced electromotive force (induced current) is greater than zero; The transmitter performs (filtering, amplifying) comparison processing on the induced electromotive force (induced current), so as to determine whether the radial offset and radial offset of the inner magnetic rotor occur, and perform local display and remote control, so as to control the magnetic pump. The deviation of the main shaft system is monitored in real time to prevent friction between the inner magnetic rotor and the inner wall of the isolation sleeve, resulting in safety accidents.
