Abstract
The utility model relates to an improved digital display table type micro high-speed centrifuger, comprising a centrifugal disc which can do centrifugal analysis for the dosage of two samples simultaneously, and a digital display system which can exactly display rotating speed and maximum centrifugal force simultaneously, wherein, the centrifugal disc is provided with an inclined reaming and a capillary centrifuge tube groove. The utility model changes the prime cowling to a cowling which is provided with a bottom and two air vents 45DEG apart in the sky to ensure the centrifugal disc running within the range from 36DEG. C to 38DEG. C, and changes the propelling centrifugal disc cover to a hand-press cover to ensure unchanged balance precision of the centrifugal disc and easy assembly and disassembly. The utility model is widely used in the biology, the medicine, and the agricultural sciences.
Description
The utility model relates to the improvement technology that a kind of numeral shows desk type high speed centrifugal machine for minim.
Existing numeral shows that micro-table model high speed centrifuge is the centrifugal pan that has oblique cutting hole and the centrifugal tube seat of capillary, can carry out the centrifugal analysis of two kinds of amount of samples simultaneously, and having can be with the digital display system (88208515.8) that advances accurate demonstration rotating speed and maximum centrifugal force, the centrifugal disk cover of this machine is the screw thread screw type, there is following problem, (1) centrifugal disk cover and centrifugal pan are to combine to carry out high-grade balance, but when using at every turn, the precession lid can not all begin from same position, therefore, after screwing, the Gai Yupan matching requirements when being difficult to reach former balance that matches, thus destroyed original balance quality requirement.Increased vibration and noise when making work like this, caused easily simultaneously that teat glass breaks in the dish, and the temperature rise because of wearing and tearing and produce with air-flow when having increased centrifugal pan work.(2) because of being left-hand thread on the lid, after experiment work finishes, increased the difficulty of getting lid, sometimes even need to unload lid with instrument.In addition, the radome fairing of this machine is the no end, ventilating system system is from body top cap central bore inlet chamber warm air, force air-flow downwards by discharging at the bottom of the machine through centrifugal pan, take heat out of, so ventilating duct is desirable not to the utmost, cause former machine work several cycles test after, the centrifugal pan temperature is unfavorable for testing continuously up to 40 ℃.
The purpose of this utility model is to overcome deficiency of the prior art, and it is hand that a kind of screw type disk cover that changes is provided, and radome fairing is that the end and the space centrifuge of 45 ° of two air vent is apart arranged.
Solution of the present utility model is as follows: the centrifuge that is provided comprises disk cover, centrifugal pan, radome fairing, motor, cartridge type magnet, coil, line interface, at the upper surface of centrifugal pan, it is equidistant radially to have an end and an axis, length is identical, can show the digital display system of centrifugal pan rotating speed and maximum centrifugal force simultaneously along the centrifugal tube seat of circumferential equally distributed capillary and.This digital readout system is by electromagnetic conversion and signal shaping, step-by-step counting and latching, and centrifugal radius is selected, memory decoding, data output, seven sections of BCD-show, latch, decoding, driver, charactron shows composition.Disk cover is a hand, the loading and unloading plate, all hand springs, and nationality ball are fastened on the centrifugal pan, at the bottom of the radome fairing band, respectively there are an air vent in bottom and wall portion, two holes in the space at a distance of 45 °, corresponding wall portion air vent, also there is an air vent at the place at the casing back side.
The utility model has following advantage compared with the prior art:
1. centrifugal disk cover changes the rotary hand that is, has guaranteed that the centrifugal pan balance quality is constant, and has loaded and unloaded quick and convenient.
2. change radome fairing of the no end for the end is arranged, and have two in the space at a distance of 45 ° air vent, changed former machine ventilation condition, test tube blood sample temperature is remained in 37 ℃ ± 1 ℃ the scope, and supercentrifuge is tested continuously.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing 2 is a hand disk cover structural representation
Accompanying drawing 3 is the dome structure schematic diagram

Seven sections demonstrations of 16--data output 17--BCD-are latched, decoding, driver
The 18--charactron shows
Among Fig. 2, centrifugal disk cover is hand disk cover (1), promptly with lid upper spring under the hand, makes the last mark of mark aligning centrifugal pan (2) on the lid, directly disk cover (1) is inserted on the centrifugal pan (2), and the back nationality ball (10) of loosing one's grip is fastened on the centrifugal pan (2).Get and need only the hand spring when covering, be easy to take off vertically upward disk cover (1), so neither destroy original balance quality, overcome the difficulty and the inconvenience of origin operation again.
Fig. 3 is end radome fairing (5), have on the cover two in the space at a distance of 45 ° air vent (11) and (3), this just makes this machine ventilating system from body top cap central bore inlet chamber warm air, through the wall portion air vent (3) of radome fairing (5), discharge heat by body back air vent (4) corresponding to this hole.Utilize the instantaneous vacuum of centrifugal pan (2) bottom of rotation at a high speed, self-rectifying cover (5) bottom vents (11) extracts the motor heat, press centrifugal pan (2) excircle tangential direction, the wall portion air vent (3) of self-rectifying cover (5) is discharged through casing back air vent (4).Make centrifugal pan (2) temperature be no more than 38 ℃, and test tube blood sample temperature can remain in 37 ℃ ± 1 ℃ scope, thereby supercentrifuge can repeated multiple times be used, not need to shut down cooling midway, be interrupted test.
Claims (1)
