Shanghai centrifuge | use electric centrifuge matters needing attention

About Shanghai centrifuge the other information please visit http://www.shlxj.com.cn/ for more details.
A, device
(1) in Shanghai's centrifuge about supply voltage: voltage fluctuations must fit within +10% national standards, some manufacturers or centrifuge is not normal operation. If the voltage to shake this above, advocate the use of regulator, for meet the grid.
(2) wire to prison: wiring room power supply to meet the requirements. Our country is a three-phase four wire system. Three-phase three-phase industrial power in the use of three-phase power, when the zero line and the ground wire separation, more important is whether the three-phase electrical or industrial, single-phase electric usually worth mentioning, the ground should be firm, prevent leakage, ground shall not be connected to the heating pipe, the water pipe.
(3) in Shanghai's centrifuge on earth to flat, strong: for large centrifuge, the device address moving floor should be strong, to ensure the normal operation of the centrifuge rotor, not trapped concave, device is fixed at the ground should be flat and firm.
(4) find a good level: looking for small horizontal accurate ruler, centrifuge lid open, find the levels in the spindle, after adjusting the adjustment bolt around 4 caster wheels drive to find a good level, pay attention to during 1 feet fail.
Two, Shanghai on the device to find balance centrifuge
Centrifuge in planning and production, imbalance brought the machining errors on the rotor dynamic balance test, have been made to remedy, but generally the centrifuge, has its promise for sample loading unbalance. Centrifuge manufacturers in order to maximum in the centrifuge promised the unbalanced index of quantitative and other manufacturers competition, try to give a larger value. In this great value, centrifuge can work, but then the occurrence of unbalanced force to N times per minute frequency suddenly impact bearing and the bracket, the centrifuge is compromised. Therefore, users of those precious centrifuge, try to find a good balance and centrifuged, life has the advantages of centrifuge.
In three, finishing the centrifugal cavity hydrops
Centrifuge operation using refrigeration, because the moisture in the air, in the centrifuge chamber frost, after stopping the cream into the water. Low speed large capacity centrifuge most foreign, no drainage holes, the centrifugal cavity water greater accumulation. At the moment, the user shall remove the rotor, finishing water. In the new device of rotor, must be installed, prevent trouble.
Four, Shanghai's centrifuge on aluminum alloy can not be corroded
Centrifuge rotor is usually made of aluminum alloy, when the intensity decreased from corrosion, simple trouble. Aluminum alloy is susceptible to corrosion after cleaning liquid, use a hair dryer to dry, or upside down for a period of time, admit dry can use. Some blood imported centrifuge, 6 aluminium Cup due 6 plastic holder without. Plastic support should bloodletting bag, prevent directly on the aluminum cup. Note tube has no crack.
If the test tube (especially the repetitive use test tube) cracks, must not use, or in the use of tube rupture will cause the rotor rotation is out of balance, can cause the broken shaft malignant incidents.
Five, Shanghai's centrifuge on the broken shaft trouble
Rotor not good place, or contain the sample unbalanced beyond the quantity is too big, centrifuges running. Imported centrifuge modern although have no balance maintenance, namely when the unbalance move beyond a certain limit, should take the initiative to power, to stop the rotation of the centrifuge. But in this case has been late, will show the malignant incidents. Malignant trouble is one of the high speed rotating shaft broken, because the Russian contingent broken shaft, the rotor does not support in the centrifugal cavity around cross, can make whole centrifuge rotating 270 degree view. Now, if the surrounding people or equipment, will be the formation of casualties and damage equipment trouble.
