The technical scheme of the utility model is that the flexible connection between the small and big supporting plates and the hydraulic damper in the middle can overcome the imbalance of shafting, The centrifuge includes a small supporting plate, a frame, a middle plate, a support, a hydraulic damper, a big supporting plate, a hexagonal nut fastening assembly, a rotor assembly, a motor sealing ring, a bearing seat, a main shaft, an internal support, a coupling assembly, a motor connection plate, a motor assembly, the upper bearing and the lower bearing of the main shaft. The beneficial effects of the utility model are that the centrifuge can take a damping effect on the vertical vibration and circumferential vibration; the centrifuge is capable of reducing the circumferential amplitude to less than 0.04mm from previous 0.1mm, reducing the longitudinal amplitude to 2m-2.9m from the previous 4-5mm and the noise to less than 70 db from the previous 64 db.
Description
Technical field
The utility model relates to a kind of centrifuge structure, particularly relates to a kind of centrifuge structure with shock-absorbing function.
Background technology
Centrifuge is as laboratory and hospital's apparatus for conducting assay, be used for separated plasma, biological products, samples such as protein, the sample rotary head (level change or angle change) of packing into, drive the rotary head rotation by drive system, under the effect of centrifugal field, the particle that density is big, material is separated from mixed liquor, the imbalance of drive system and rotary head system, bearing problem or the like all can be brought the vibration and the noise of complete machine, and uneven unavoidable in processing, common oscillation damping method adopts spring, the combined shock absorption of rubber etc. has one-level that secondary and even multistage vibration damping are also arranged, but all unsatisfactory, vibration, noise problem is more outstanding in high rotating speed and jumbo centrifuge, is one of main difficult problem of centrifuge and even slewing performance.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is the purpose of this utility model place that a kind of centrifuge with shock-absorbing function is provided, the technical solution of the utility model is by little, big palette and middle hydraulic damper flexibly connect, overcoming axle is the imbalance that imbalance or other reasons have caused rotary system, the technical solution of the utility model is to come specific implementation by following technical measures, a kind of centrifuge with shock-absorbing function, it is characterized in that it comprises little supporting plate, the frame intermediate plate, support, hydraulic damper, big palette, the hex nut fastening assembly, rotor assembly, motor seal circle, bearing block, main shaft, interior bearing, coupling assembly, connecting plate for electric motor, electric machine assembly and main shaft metal (upper, wherein: electric machine assembly, coupling assembly, main shaft, the main shaft metal (upper is formed to drive, they are by bearing block and interior bearing, and connecting plate for electric motor is fixed on the little supporting plate with hex screw, little supporting plate is fixed on the big palette by three hydraulic damper, and big palette is lifted on the intermediate plate of frame; Described hydraulic damper specification is divided 25kg, 30kg, 32kg etc., the structure of hydraulic damper is that the bottom is the circular drain pan that metal plate punching is made, firmly connect between rubber and the drain pan and seal, the centre on top is a metal gasket, all around be hard rubber, formed a rubber bag tank, the rubber bag tank the inside is full of hydraulic oil, but in the middle of the bottom is the valve of topping up, acting in conjunction by rubber and hydraulic oil liquid comes vibration damping, is soft outside but hard inside oscillation damping method, and it is little to be subjected to vibrating little time distortion, vibrate that rubber deforms big the time, but liquid compressive deformation amount is little, and liquid can conduct compression shock the energy even distribution on all directions, stressed evenly in all directions, thereby damping effect is preferably arranged.
Good effect of the present utility model is to have adopted motor is installed on the little supporting plate, flexibly connect by little, big palette and middle hydraulic damper, big palette is lifted on the intermediate plate of centrifuge frame, easy for installation, damping effect is good, not only can play damping action, can play the effect of vibration damping to the vibration of circumferencial direction the vibrations of vertical direction; The pressure of the hydraulic oil in the hydraulic damper can conduct in all directions in addition, reaches the cushioning effect on all directions, and the hydraulic damper below is connected on the big palette of centrifuge frame.When the rotor assembly bringing onto load, starter motor makes the drive system rotation, drives rotor assembly and load and together rotates, because axle is the imbalance that imbalance or other reasons have caused rotary system, uses hydraulic damper after vibration and noise all to have significantly and descends.The utility model can make the amplitude of circumference from being reduced to below the 0.1mm below the 0.04mm, and pitch amplitude is reduced to 2-2.9mm by 4-5mm, and noise is from being reduced under 64 decibels below 70 decibels.
What the utility model was suitable for similar rotating mechanism is the equipment of feature with the hydraulic damper.
