Low-speed centrifuge cleaning method
1. Clean the centrifuge chamber and rotor and dry the condensate in the chamber.
2. Open the door after use until the chamber returns to normal temperature.
3. Balance the sample before centrifugation.
4. Pay attention to disinfection and sterilization after centrifugation.
5. Pre-cool the rotor if necessary, maintain and store the rotor, and pay attention to the protection ring at the bottom.
6. When the main power indicator is off, check if the indicator fuse and the indoor distribution board fuse are blown. Also check whether the power line is in good contact. If the fuse is broken, replace the fuse and keep the circuit unblocked.
7, should also check the vacuum pump table and oil pressure indication value, if the oil pressure is too high and the host can not start, it is necessary to check whether the oil circuit is blocked, especially whether the throttle hole is smooth, if not smooth, it should be cleaned to make it smooth.
8. The bearing is damaged or the rolling is blocked. There is no oil in the bearing or there is more dirt in the bearing, which causes the frictional resistance to increase. If the motor does not reach the rated speed, the bearing should be cleaned or replaced in time.
9. There is a layer of oxide on the surface of the commutator. Even if the bump is uneven or the brush does not match the outer edge of the commutator, the rotation speed can be lowered. The commutator and the brush should be cleaned to make the contact good.
