Low speed large capacity centrifuge cleaning method

Low speed large capacity centrifuge cleaning method

On low speed large capacity centrifuge the other information please visit http://www.shlxj.com.cn/ for more details.

New skills in low speed large capacity centrifuge respectively according to the state of particles in a suitable place in the centrifugal and start up. Centrifugal respectively skills also resume the generations of conversion, from low speed large capacity centrifuge, high-speed centrifuge, centrifuge speed to the preparative ultracentrifuge, super capacity refrigerated centrifuge. Settlement is not the same density, size or shape of the particles in different speed centrifugal places, so a roughly spherical non homogeneous mixture, can use the centrifugal method to respectively, centrifuges to further study of Biochemistry, respectively, a lot of matter. We recommend the following centrifuges disadvantages detection and cleaning method:
1, the main power indicator light, when should view the carbon brush wear level, such as carbon brush wear beyond 1/3 of the total, should be timely conversion of carbon brush new.
2, the main power indicator light does not light, check the indicator fuse and indoor distribution fuse board can fuse together, see power line can touch the outstanding, low speed large capacity centrifuge such as fuse fuse and adhere to the circuit should be converted to dredge.
3, should also check the vacuum pump and the oil pressure indicator value table, such as the oil pressure is too high and the host can not start, must check the oil can jam, particularly saving holes can dredge, if not dredging should be cleaned to dredge.
4, bearing damage or tumbling blocked, bearing of oil or bearings in the dirt is more and cause friction resistance increases, the motor is not up to the extra speed, low speed large capacity centrifuge recommendations should be timely cleaning or conversion of bearing.
5, the commutator surface has a layer of oxide, so that burning rough or brush and outer profile does not conform to also can make the speed decreased, should liquidate commutator and brush, the touch of outstanding.
6, such as the rotor winding short circuit or open circuit, use a multimeter to check, medical centrifuge re winding. The rotor when in use can be due to metal fatigue, speeding, stress, chemical corrosion, selected properly, use back because of balanced and temperature out of control caused by centrifugal tube split sample leakage, rotor damage.
7, cleaning centrifuge cavity and a back cavity of condensed water, and dry.
8, after using them to open the door, until the cavity rehabilitation at room temperature.
Equilibrium of samples to 9, centrifugal before.
10, centrifugal later to pay attention to disinfection and sterilization.
11, when necessary, pre cooling rotor, protection and kept back, pay attention to the protection of counting ring at the bottom of the.
