Widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, papermaking and other industries as well as environmental protection, municipal management, water conservancy construction and other fields. The measuring principle is Faraday's law of electromagnetic induction. It is an instrument for measuring the flow of conductive fluid according to the electromotive force induced by a conductive fluid when magnetic field is applied. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke housing. .
Product introduce:
In the machining process, the common methods of sheet cutting are manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting. Manual cutting is flexible and convenient, but the quality of manual cutting is poor, the size error is large, the material waste is large, the subsequent processing workload is large, and the labor conditions are harsh and the production efficiency is low. Among the semi-automatic cutting machines, the profiling cutting machine has better quality of cutting workpieces. Because it uses a cutting die, it is not suitable for single piece, small batch and large workpiece cutting. Although other types of semi-automatic cutting machines reduce the labor intensity of workers, they have simple functions and are only suitable for cutting parts with relatively regular shapes. Compared with manual and semi-automatic cutting methods, CNC cutting can effectively improve the efficiency and quality of plate cutting, and reduce the labor intensity of operators. With the development of the modern machinery industry, the requirements for the work efficiency and product quality of plate cutting processing have also increased at the same time, so the market potential of CNC cutting machines is still very large, and the market prospects are relatively optimistic.

    Electromagnetic flowmeter failure analysis during operation:
    Run-time failure is a failure that occurs after the electromagnetic flowmeter has been commissioned and operated for a certain period of time. Common operational failures are caused by factors such as the adhesion of the inner wall of the flow sensor, lightning strikes, and changes in environmental conditions.
    1, sensor inner wall adhesion layer
    Since electromagnetic flowmeters are commonly used to measure dirty fluids, after a certain period of operation, an adhesion layer accumulates on the inner wall of the sensor and often causes failure. These faults are often caused by too much or too little conductivity of the adhesion layer. If the attachment is an insulating layer, the electrode circuit will be open circuit, the meter can not work properly; if the adhesion layer conductivity is significantly higher than the fluid conductivity, the electrode circuit will appear short circuit, the instrument can not work properly. Therefore, the adhered scale layer in the measuring tube of the electromagnetic flowmeter should be removed in time.
    2, lightning strike
    Lightning strikes easily induces high voltage and inrush currents in the instrument line, causing damage to the meter. It is mainly introduced through the power line or the excitation coil or the flow signal line between the sensor and the converter, and is particularly introduced from the control room power line. 
Usually, the CNC cutting system automatically processes the processed parts according to the pre-programmed processing program (the commonly used drawing software AUTOCAD). We put the machining process route of the part, process parameters, tool motion trajectory, displacement, cutting parameters (spindle revolutions, feed, back-feeding amount, etc.) and auxiliary functions (tool change, spindle forward rotation, reverse rotation, The cutting fluid is turned on and off, etc.), according to the instruction code and program format specified by the CNC cutting system, write a processing program list, and then record the content of the program list on the control medium (such as perforated paper tape, magnetic tape, disk, magnetic bubble, etc.). memory), and then input into the numerical control device of the numerical control machine tool, thereby directing the machine tool to process the parts.
This whole process from the analysis of the part drawing to the production of the control medium is called the compilation of the numerical control program. The difference between CNC cutting equipment and ordinary manual and semi-automatic cutting equipment in processing parts is that CNC cutting equipment automatically processes parts according to the program, while ordinary manual and semi-automatic cutting equipment needs to be operated by humans, we only need to change the control machine action. The program can achieve the purpose of machining different parts. Therefore, CNC cutting equipment is especially suitable for processing parts with small batches and complex shapes that require high precision!
Since the CNC cutting equipment needs to process parts according to the program, after the programmer has compiled the program, it is input into the CNC system to direct the machine tool work. Program input comes through the control medium. In this way, the CNC system is used to control the finished processing parts, and the graphics can be modified in time by the drawing staff, which can be used more freely, and the accuracy of the workpiece parts is also greatly improved compared with that of semi-automatic cutting equipment!
