Automatic decapping centrifuge fault repair

On automatic decapping centrifuge the other information please visit http://www.shlxj.com.cn/ for more details.

(1) a sensation strong, big noise
Check the automatic hat centrifuge can exist, not balanced question fixed machine nut loose, if have, fastening; check bearing can be damaged or twists, such as there is conversion bearing; machine cover deformation or range is not correct attack conflict, such as there is on one check adjustment.
(2) motor rolling electricity
Automatic decapping centrifuge mainly on the power line, plug, socket suspend view, if damage should be changed; if no doubt check band switch or rheostat can damage or connection to get rid of, such as damage or get rid of the conversion component damage, ab initio welding connection; if there is no question is checked to see whether there is a motor coil break off (or circuit breaker internal), such as the connection ring break off to welding. As is the coil internal break only rewind coil.
(3) the motor speed is not up to the rated speed
The first view of bearings, such as damage to the bearing bearing bearing internal conversion, such as lack of oil or dirt too much should clean the bearing and grease. Check whether there are abnormal commutator or brush and detonation surface cooperation can meet, such as the commutator surface there is abnormal, such as automatic decapping centrifuge has a layer of oxide is to use fine sandpaper to check them; such as the commutator and brush cooperation does not conform to it should be adjusted to touch the outstanding; such as automatic decapping centrifuge no more questions check whether a rotor coil short-circuit phenomenon, such as automatic decapping centrifuge should be rewound coils; check whether the adjustable speed regulation resistance W, if there is no damage, measuring SCR, SCR2 thyristor turn-on voltage of Ug can be attributed to normal, if normal measuring SCR1, SCR2 conduction, normal positive guide through reverse cut-off, conversely, conversion of silicon controlled rectifier.
(4) the spark between automatic centrifuge commutator and a big hat
Check the automatic decapping centrifuge can flat commutator surface, such as uneven surface can be polished with sandpaper, if brush and touch bad, will be part of polished with fine sandpaper, start from the adjustment between the brushes and commutator brush cooperation; if in doubt, you can only change the brush; the assumption above without doubt, is to see whether the magnetic field coil there are some short circuit or coil on the ground, some open or shorted rotor coil is still. Magnetic field coil and the rotor coil whatever bad to rewind the field coil or rewind the rotor coil.
(5) the centrifugal indoor cooling
Automatic decapping centrifuge refrigeration is selection austerity type single-stage transpiration cycle refrigeration, the refrigeration process must be composed of two system. One is the control system, the second is the refrigeration system. Visible, the centrifugal chamber without cooling (i.e. no refrigeration) there may be control system and a refrigeration system appeared shortcomings, first check the confirmation is control system is still appear disadvantages of refrigeration system. Assuming the automatic hat centrifuge is the compressor operation and centrifugal indoor cooling, maybe that is refrigeration system leakage fluorine or infarction, will be on the refrigeration system leak ab initio fluoride; assume automatic decapping centrifuge compressor is not running, is the control system shortcomings, first check the centrifugal chamber temperature setting value, whether the normal flash changes and assuming normality check from the ventricular temperature sensor and inserted in the plug and wiring, can touch the outstanding, compressor starter (PTC) can damage the compressor coil wire, check and treatment.
