Description
Technical field:
The utility model belongs to the electronic product technical field, is specifically related to the centrifuge unbalance protection device of band angular deflection sensor of the detection usefulness of the non-equilibrium state that produces in a kind of centrifuge running.
Background technology:
Existing centrifuge often produces vibration at work, and violent vibration directly influences the operate as normal of centrifuge, jeopardizes personal safety and causes device damage when serious.So must monitor to the vibration of centrifuge.And the vibration of centrifuge is uneven in case produce and will increase along with the rising of rotating speed mainly from the unbalance dynamic that rotor loading produced.Generally find out imbalance by the swing that detects the centrifuge motor shaft, traditional method has: mechanical location switch, mistor (MSR), supersonic sounding, acceleration sensing etc.Wherein the widest with the mechanical location switch application.But thisly find out unbalanced method and can only play in particular range and to limit the unbalanced effect of centrifuge rotor, can not really detect unbalanced position of centrifuge and amplitude of fluctuation.Up to the present, also there are not the better substitute products of performance to occur.
The utility model content:
The purpose of this utility model is to overcome above-mentioned defective and provide a kind of simple to operate, centrifuge unbalance protection device easy to detect.Influencing the unbalanced factor of centrifuge mainly is rotor loading imbalance and motor speed.Usually the amount of unbalance of centrifuge is directly proportional with rotor unbalance value, and rotating speed is inversely proportional to.During low-speed stage, motor speed is bigger to the uneven influence of centrifuge, high speed stage, and the laod unbalance amount is to influence the unbalanced principal element of centrifuge.This just need carry out a comprehensive quantitative analysis to the influence of this two factor, thereby judges under which kind of combined situation, and centrifuge can produce imbalance.
The utility model is to realize like this, it is by rotor, rotator seat, driving shaft, cushion blocking, the driving wheel variable-frequency motor, drive belt, driven pulley, support, the angular deflection sensor constitutes, on the main shaft of variable-frequency motor central authorities, be provided with driving wheel, be installed on driven pulley in the driving shaft lower end, be installed on the driving belt on driving wheel and the driven pulley, on driven pulley, be provided with driving shaft, at driving shaft, be provided with the angular deflection sensor, be provided with rotator seat and the rotor that is attached thereto in the driving shaft upper end, at the driving shaft periphery cushion blocking is set in addition, locate by support and with the driving shaft of rotor, on support, be installed on cushion blocking, on cushion blocking, be installed on and be attached thereto location-plate, this dress is that the angular deflection sensor is installed on the driving shaft, adopt the angular deflection sensor to detect the uneven function of centrifuge, described angular deflection sensor resolution height, noise is low, and operating temperature range is wide, it can accurately measure the deviation angle of centrifuge motor shaft, and output simulates signal and carries out data analysis for 16 central processing units.This apparatus system control is to adopt 16 central processing units, and central processing unit is compared with the angular deflection scope of setting by the analog signal that analyzing and processing detects, and makes relevant control.
