When the rotor is rotating and the power is turned on, it is
strictly prohibited to use emergency tools to open the door cover!
2.33 cavity system includes a stainless steel inner liner and a rubber sealing ring. It
can provide a stable working environment.
2.3.4 This equipment uses a variable frequency motor to directly drive the rotor of the
load sample to rotate together. The drive system adopts a direct drive method, which
ensures high precision in matching the rotor with the shaft and smooth operation.
2.3.5 The rotor system is composed of various rotors (see Table 1: Rotor Types and
Technical Parameters for details), centrifugal test tubes and other related accessories.
The function of the rotor is to rotate the load sample at a certain speed, creating a
relative centrifugal force field, thereby achieving the purpose of separating the sample.
Since the centrifugal force reached when the rotor rotates at low speed is thousands of
times more than the Gravitational acceleration g value of the earth, it is very
important for the safe use and careful maintenance of the rotor!
2.3.6 The base system consists of a rack, a base plate, a body shell, and rubber support
feet.
2.3.7 The power supply system includes power sockets and switches, which are
responsible for the mains power supply required for the normal operation of the
machine.
2.3.8 The control system includes settings for rotational speed and centrifugal force,
operating time, selection of lifting and lowering rate, control of the entire machine
display system, and alarm system. To ensure the normal operation of the machine and
the personal safety of the operator, please do not disassemble the machine casually!
The display system consists of a 7-inch color LCD touch screen and a PET touch
keyboard panel (control panel). It is a medium for human-machine dialogue. It can
synchronously display various parameters set and track the actual changes of various
parameters. In addition, it can also display and alarm various faults.
2.3.10 The alarm system is equipped with alarms for door cover failure, overspeed,
imbalance, overvoltage, etc. In case of overspeed, door cover opening, imbalance and
other faults of the machine, the system will give an alarm. At this time, the buzzer will
give an alarm sound, and an error Tooltip will appear in the middle of the screen. The
machine cannot be started (it is not allowed to start). The running machine will
automatically stop until the fault is eliminated, and the machine can be restarted. Note:
To eliminate the alarm sound emitted by the buzzer, press the stop button on the
control panel.
2.4 Security Protection Agency
The high-speed freezing centrifuge has a series of safety protection mechanisms:
The frame and protective steel ring are made of steel plates, and the internal cavity is
made of stainless steel inner liner;
The door cover adopts an explosion-proof structure, and there is a locking mechanism
at the front of the door cover. Only when the centrifuge is powered on and the rotor is
