The centrifuge is a device that separates different substances under the action of a certain centrifugal force due to the different sedimentation coefficients of different substances. Just like a tube rotates like a wheel, the mixture contained in it varies according to the mass of the particles, so the centripetal force required for centrifugal movement will separate the material. F = MV ~ 2 / R formula. They are generally of great use and can also purify uranium to make high-uranium atomic bombs.
The role of the centrifuge is well used in public production, such as the dehydration of chemical materials. Drying requires the use of a centrifuge. This is the centrifuge speed measurement system. The separation of oil and fat uses a disc separator, and the processing of starch uses a horizontal scraper centrifuge, etc., all of which are well used.
The role of the centrifuge is not only in industry, but also in the analysis of laboratories and other industries. In short, the role of the centrifuge is a device that uses the principle of centrifugal force to separate different kinds of materials.
Main functions of centrifuge speed measurement system
The centrifuge speed measurement system has three different detection and control methods, namely: automatic detection, local control, and remote control. The system generally works in automatic detection mode; local control method and remote control method are process operators in accident handling Or selected for the performance analysis of the centrifuge.
The system works in automatic detection mode, automatically turns on all sensors in turn, and generates OB (single out-of-step) and OP (single machine loss) signals in the second inspection cycle, and in the third inspection cycle Form FB (out-of-synchronization in groups), FP (out-of-group loss), A3 (accident protection) and CH (fault signal), execute accident protection commands and send alarm signals to the central control room.
The system works in the local control mode. The process operator can also select the automatic patrol inspection and manual patrol inspection mode. In the automatic patrol inspection mode, all the sensors are automatically turned on for detection, and the signals OB, OP, FB are generated. , FP, A3 are displayed on the spot, and the signals CH and CT are sent to the central control room. In the manual inspection mode, the sensor address is manually selected to detect the frequency and power supply frequency of the centrifuge; the sensor is shielded and unshielded; automatic search is generated The address and number of sensors for signals OB and OP.
The system works in the remote control mode, you can automatically or manually turn on the sensor for detection on the console of the central control room, display the frequency of the sensor and the OB, OP, FB, FP, A3, CH signals; search to form OB, OP The number of sensors; shielding and unblocking the sensors; you can also use the computer (CM-2M) in the central control room to turn on all sensors in sequence to detect, store and print the frequency of the sensors, and calculate the friction power consumption of the centrifuge.
