News Detailed Information
Ultra-high-speed refrigerated centrifuge operation and Notes |
| Author： Date：2009-07-03 |
1.the operational procedures:
1) will be placed in an equivalent sample test tube, and turned into symmetry;
2) tightening shaft nut, cover to cover doors and equipment will be connected to the power supply, measured the speed of light is bright, LED display, "00000", said the equipment had been connected to power;
3) key to start operation by the apparatus, equipment manufactured in accordance with the parameters set by the work of the LED display the actual speed and temperature; For cooling, the key to open by refrigeration, digital temperature control cavity shows that the actual temperature.
4) For the equipment to adjust operating parameters:
(1) Set the time and operating speed of operation: can function keys, so that the indicator light, LED display that is the value of digital control in a number of flashes in, available at this time and "","" " "Key combination to adjust the parameters required to value, and memory storage button to confirm.
(2) Set temperature: refrigeration function keys, so that the (minimum or maximum) bright light, LED display that is the value of digital control in a number of flashes in, available at this time and "","" "" Key combination to adjust the parameters required to value, and then a cooling function keys, from the set-up process.
(3) machines running LED display speed, when the need to view the other parameters, can function keys, so that the parameters of the indicator light, the LED display that Value. When the equipment arrived at the set time or half-way down, down in the process of digital display speed, is a normal phenomenon.
2.attention:
1). In order to ensure the safety and effectiveness of centrifuge equipment to be placed on a solid level of the table, engineering plastics can not be placed on doors to build anything; samples must be symmetrical and placed in the boot to ensure that the former has been tightened nuts;
2). To carry out regular checks and turned the experiment using centrifugal whether there is a crack pipe, such as aging, if any should be replaced in a timely manner;
3). After the experiment, the apparatus will be required to wipe clean to prevent corrosion;
4). If the sample accounted for more than 1.2g/cm3, the highest speed n = nMax ? SQRT (1.2 / proportion of the sample);
5). 6mm smaller than the length of the brush machine, it must be replaced in a timely manner;
6). In the centrifuges came to a complete stop is not the case not to open the door cover;
7). Equipment must be reliable ground;
8). The instrument, such as voltage instability in the region, regulators should be created to ensure that the equipment to play the best performance.
9). Plug in the power, open the power switch, equipment control system of digital display, please stop button, the speed of digital display OPEN, electronic door locks moves to build Weitai automatic doors, this time by hand can open the door cover, such as cover Automatic doors can not be Weitai, 3 seconds to be built by hand to open the door, more than 3 seconds, electronic door locks and locked the door automatically. If the cover open the doors, must stop button panel on the speed of digital display OPEN, to open the door cover.
10). If the user to set the parameters for the factory to make any changes, please test solution with an equivalent sample of the test-tube rotor into symmetrical hole, the door cover to cover. Then operate direct operation of the key. For change parameter settings, press the panel to conduct the Settings button and memory, according to the operation after operation of key equipment. The end of the show running from 0 to OPEN, then you can open the door cover, such as 3 seconds did not open the door, OPEN become 0, according to the need to stop the emergence of key OPEN, 3 seconds to open the door. |
