Description
Technical field
The utility model relates to a kind of supercentrifuge.
Background technology
Supercentrifuge, comprise frame, frame is provided with rotating assembly, rotating shaft is provided with drum assembly, in frame, sealing is provided with housing unit, and frame is provided with the actuating unit of drive shaft, and described rotating assembly comprises the mount pad of the hollow be arranged in frame, main shaft is rotated by disposed thereon two groups of bearings and is located in mount pad, and Bearing inner fills lubrication butter.In the process of centrifuge High Rotation Speed, quickly, often need to add, dismounting is inconvenient and labour intensity is large for the loss of lubrication butter.And centrifuge runs up bearing portion temperature rise can be made large, bearing life is shortened.
Utility model content
Technical problem to be solved in the utility model is: the supercentrifuge that when providing a kind of use, bearing temperature rise can not transfinite.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of supercentrifuge, comprise frame, frame is provided with rotating assembly, rotating shaft is provided with drum assembly, in frame, sealing is provided with housing unit, frame is provided with the actuating unit of drive shaft, described rotating assembly comprises the mount pad of the hollow be arranged in frame, mount pad comprises the bearing construction section at two ends and connects the installation stage casing of two sections of bearing construction sections, main shaft is rotated by disposed thereon two groups of bearings and is located in mount pad, mount pad is respectively equipped with outside two groups of bearings the bearing cap of gland bearing, annular oil groove together with bearing cap is provided with at least with the contact surface of main shaft, main shaft is provided with in the position corresponding to annular oil groove the annular drainage trough that cross section is V-arrangement, bearing cap is provided with the Oil Guide passage being communicated with bottom annular oil groove and installing stage casing inner chamber, in the installation of mount pad, pars infrasegmentalis is provided with oil return opening, mount pad is being respectively equipped with oil inlet pipe corresponding to two groups of bearing places, mount pad is provided with seal cover outside the bearing cap near drum assembly place, is provided with labyrinth sealing near between the bearing cap and seal cover at drum assembly place.
As the preferred scheme of one, being respectively equipped with temperature-measuring port corresponding to two groups of bearing places on described mount pad, in temperature-measuring port, be provided with temperature sensor.
As the preferred scheme of one, the exit of described oil inlet pipe is provided with nozzle.
The beneficial effects of the utility model are: the bearing due to main shaft have employed oil cooling but, cold oil passes through oil-in spray on two place's bearings, to reduce bearing temperature, the oil entering bearing block inside enters into coolant pump and cools through annular oil groove, Oil Guide passage, oil return opening and recycle.
Due to mount pad being respectively equipped with temperature-measuring port corresponding to two groups of bearing places, in temperature-measuring port, be provided with temperature sensor, give the alarm, to remind operating personnel to avoid the generation of accident if temperature exceedes the siren that setting requirement can trigger connection.
Because the exit of oil inlet pipe is provided with nozzle, can ensure that lubricating oil can accurately spray in bearing.
