Abstract
The invention discloses a high-speed centrifuge. The high-speed centrifuge comprises a rack. A rotary shaft assembly is arranged on the rack. A drum assembly is arranged on a rotary shaft. A shell assembly is arranged on the rack in a sealed mode. A power mechanism for driving a spindle is arranged on the rack. The rotary shaft assembly comprises an installing base arranged on the rack. The installing base comprises bearing installing sections at the two ends and a middle installing section for connecting the two bearing installing sections. The spindle penetrates into the installing base through two sets of bearings arranged on the spindle. Bearing covers are arranged at the portions, on outer sides of the two sets of bearings, of the installing base. At least one annular oil tank is arranged on the contact surface of the bearing cover and the spindle. Oil guide passageways for allowing the bottoms of the annular oil tanks and an inner cavity of the middle installing section to be communicated are arranged on the bearing covers. An oil return port is formed in the lower portion of the middle installing section of the installing base. Oil inflow pipes are arranged at the portions, corresponding to the two sets of bearings, of the installing base respectively. Sealing covers are arranged at the portions, on the outer sides of the bearing covers, of the installing base. Labyrinth seals are arranged between the bearing covers and the sealing covers. When the high-speed centrifuge is used, the temperature rise of the bearings cannot exceed the limit.
Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 solution adopted in the present invention 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 invention has the beneficial effects as follows: 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.
