Abstract
The utility model relates to a fairwater type centrifugal rotor for centrifuges, which comprises a rotor, a rotary shaft and a centrifugal cup, the rotor is arranged on the rotary shaft, the centrifugal cup is arranged on the rotor, the fairwater type centrifugal rotor also comprises a fairwater, a fairwater cover and a rotor connector, the fairwater is fixed on the rotor connector, the rotor connector is fixed on the rotor, and the top of the fairwater is covered by the fairwater cover. Compared with the prior art, the fairwater type centrifugal rotor has the advantages of large capacity, high rotational speed, low noise and the like.
Description
Technical field
The utility model relates to a kind of centrifuge, especially relates to the centrifugal rotor of a kind of centrifuge with kuppe.
Background technology
Centrifugal mechanism causes sample to be separated is inserted in rotor by containers such as pipe or bottle, thereby then makes rotor high-speed rotation separation and refine this sample.The purposes of rotor is according to the difference of rotary speed and difference, and comprises various types of rotors, and for example the fixing angle rotor of pore and the bucket that is mounted with pipe swing to the swing-rotor of level from vertical state along with the rotation of rotor.
The centrifuge of existing level rotor, as TDL-40B etc., heap(ed) capacity 100ml * 4, maximum speed 4000rpm, noise has reached 70dB.Rotating speed is low, and capacity is little, and noise is large, can not meet client's demand.
Owing to having increased the capacity of centrifuge, heap(ed) capacity has reached 500ml * 6, rotating speed 5000rpm, and the overall weight of horizontal rotor is large, and centrifugal radius is large, Centrifuge Cup Heavy Weight, overall weight has reached 15kg.So can produce very large resistance in centrifugal running, send very large noise.Owing to will reaching certain centrifugal force, certainly will to increase rotating speed, produce shake, cause centrifugal weak effect, noise is large.
Summary of the invention
The purpose of this utility model is exactly to provide the centrifugal rotor of the centrifuge that a kind of capacity is large, rotating speed is high, noise is low with kuppe in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: the centrifugal rotor of a kind of centrifuge with kuppe, comprise rotor, rotating shaft, Centrifuge Cup, described rotor is arranged in rotating shaft, described Centrifuge Cup is arranged on rotor, it is characterized in that, also comprise kuppe, water conservancy diversion cover cap, rotor connector, described kuppe is fixed on rotor connector, described rotor connector is fixed on rotor, and described water conservancy diversion cover cap lid is located at kuppe top.
Described rotating shaft top is provided with rotary head nut, and described water conservancy diversion cover cap center is provided with screw, and water conservancy diversion cover cap is bolted on the rotary head nut at rotating shaft top.
Described rotor center is set in rotating shaft, and described rotor connector is fixed on rotor center place.
Described rotor connector connects respectively rotor and kuppe by bolt.
Described rotating shaft is provided with axle and embraces, and described kuppe is provided with a loop connecting platform near rotating shaft place, and this loop connecting platform butt axle is embraced, and described rotor connector is set in outside rotating shaft, and its top connects rotor, and bottom connects ring-type connecting platform.
Compared with prior art, the utlity model has following advantage:
1. increased once centrifugal heap(ed) capacity to 500ml * 6
2. improved rotating speed by original 4000rpm to 5000rpm
3. owing to having adopted kuppe, control the formation of turbulent flow in centrifugal chamber, greatly reduced noise when centrifugal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, the centrifugal rotor of a kind of centrifuge with kuppe, comprise rotor 6, rotating shaft 9, Centrifuge Cup 2, kuppe 5, water conservancy diversion cover cap 4, rotor connector 8, described rotor 6 is arranged in rotating shaft 9, and described Centrifuge Cup 2 is arranged on rotor 6, and described kuppe 5 is fixed on rotor connector 8, described rotor connector 8 is fixed on rotor 6, and described water conservancy diversion cover cap 4 lids are located at kuppe 5 tops.Rotating shaft 9 tops are provided with rotary head nut 1, and water conservancy diversion cover cap 4 centers are provided with screw, and water conservancy diversion cover cap 4 is fixed on the rotary head nut 1 at rotating shaft 9 tops by bolt 3.
Described rotor 6 center are located in rotating shaft 9, rotating shaft 9 is provided with axle and embraces 7, rotor connector 8 is set in outside rotating shaft 9, and do not contact with rotating shaft, rotor connector 8 tops are connected with rotor 6 by bolt, and junction is in rotor center near rotating shaft 9 places, and kuppe 5 is provided with a loop connecting platform near rotating shaft 9 places, this loop connecting platform butt axle embraces 7, and rotor connector 8 bottoms are bolted the loop connecting platform of kuppe 5.
This programme is that the rotor with kuppe is arranged on the centrifuge of LXJ-IIC, this kuppe structure is, rotor fitting 8 is equipped with in rotor 6 belows, rotor fitting 8 is connected 6 by kuppe 5 with rotor, and in rotating shaft 9, cover has axle to embrace 7, and rotating shaft 9 centers are aimed at rotor 6 centers, form shaft hole matching, rotary head nut 1 is tightened, and rotary head nut 1 intermediate projections part is aimed at water conservancy diversion cover cap 4 centers, surrounding and kuppe sealing 5.Centrifuge Cup 2 is hung on rotor.Formed so a relatively space for sealing, when centrifugal, kuppe 2, along with rotor is rotated counterclockwise together, has reduced the resistance of air, has reduced noise, has improved rotating speed.Kuppe diameter is 460mm, is highly 185mm, and stainless steel 304 is made, and thickness is 1.5mm.Rotating speed is 5000rpm, heap(ed) capacity 500ml * 6, Max RCF 5000g, noise 65dB.
