Centrifuge machinery inspection project
Centrifuges have many advantages as a means. For example, ultracentrifugation can be operated at low temperatures, protecting the activity of biomacromolecules. The preparative centrifuge has a large loading capacity and can separate and purify a few grams of sample at a time, which is much larger than that of chromatography and electrophoresis. The analysis centrifuge can not only measure the molecular weight of the substance, but also the purity, conformation and sedimentation coefficient of the substance. Therefore, centrifugation technology plays an important role in biological research and is the most convenient and effective tool for isolating and purifying cells, viruses, proteins, nucleic acids and enzymes.
During the high-speed rotation of the centrifuge, the movement caused by the centrifugal force causes the solid matter suspended in the liquid to form a sediment, that is, the mass or volume of the suspended body fluid moves to the direction of the largest radius of the rotor, and the mass or The smaller part is deposited near the radius of the rotor.
For the inspection of centrifuge machinery:
Cleanliness of hydraulic oil: check every month and replace if abnormality is found.
⊙Noise: Confirm every shift, if there is any abnormality, immediately repair.
⊙ Current: Monthly inspection, should be within the rated range.
⊙ Pressure: Each shift is confirmed within the system's rated range.
Oyster oil temperature: confirmed every shift, below 55 °C.
⊙Sealing: Check every line and check whether there is oil leakage in each pipeline and installation surface. If yes, turn off the power supply for maintenance.
⊙Check each proximity switch regularly
⊙ Regularly check the setting current of each thermal relay
⊙ Regularly check whether the vibration detecting device is sensitive and reliable
⊙Check if the power distribution cabinet fan is in good condition and whether there is cover on the surface
吸 Regularly vacuum the control cabinet (recommended once a month)
⊙ After the power is turned off for a long time, the main circuit must be insulated before it can be energized.
⊙ Periodic calibration of oxygen meter
