1 high speed refrigerated centrifuge assumptions often appear the motor can not start phenomenon in the use process, or a power indicator light does not light, check the indicator lamp fuse and indoor distribution fuse board can fuse, check the power line can touch the outstanding at the same time.
2 high speed refrigerated centrifuge such as rotor winding short circuit or open circuit, use a multimeter to check, ab initio winding. The rotor in the use of metal fatigue, due to speeding, stress, chemical corrosion, improper selection, turn back because of balanced and temperature control in the application of centrifugal pipe incurred split sample leakage, rotor damage. The main operator skillful manipulation begged operating procedures, accurate selection of suitable for centrifugal pipe and the centrifugal rotor, pay attention to the severe control every step of the operation operation order, try to reduce as the unnecessary damage, used in the safety coefficient of rotor and ensure period.
3 high speed refrigerated centrifuge in working process, if any abnormal phenomenon will be shut down immediately, shall not be forced to work, in order to avoid missing or unexpected trouble unnecessary.
4 high speed refrigerated centrifuge bearing damage or rolling blocked, bearing of oil or bearing in with dirt more and cause friction resistance increases, the motor is not up to the extra speed, should be timely cleaning or replacement of bearings. The commutator surface has a layer of oxide, so that the firing uneven or brush and the outer edge do not coincide, also can make the speed landing, should liquidate commutator and brush, the touch of outstanding.
5 if the oil pressure is too high and the host can not start, please check the oil can jam, particularly saving holes can dredge, if not dredging should be clean to dredge.
6 high speed refrigerated centrifuge launched one of the reasons why the refrigeration effect and the difference is the power is disconnected, should check the power supply and the fuse respectively, and the voltage is too low, safety installation defects can make freezer can't start.
