Flowmeter measurement medium has many kinds, there are also normal corrosive, in view of the corrosive medium, on the flowmeter selection must do anti-corrosion corrosion process. Flow meter manufacturer technology below small make up, to explain about flowmeter flow measurement of corrosive medium, instructions are as follows: 1, the corrosion phenomenon of corrosion is the metal in the environment destruction phenomenon due to chemical action. All metals and alloys for some specific environment can be decay resistance, but in other environments is sensitive to corrosion and. In general, for all the bad corrosion resistance of metal materials used in industry is not there. 2, corrosive medium of the damage to the flow measuring medium corrosion resistance is a serious threat to the flow measurement instrument: a. Corrosive medium flow measurement instrument and direct contact with the key components of medium corrosion, damage, loss of function. For example, the corrosion damage of diaphragm, differential pressure transmitter silicone oil leakage and complete failure. Electrode electromagnetic flowmeter leakage caused by corrosion medium, which leads to the excitation coil burned down, etc. b。 Flow measurement instrument of the key parts for a long time by the corrosion of corrosive medium and change the geometry size, results in the decrease of meter accuracy. For example, after the rotor in the rotameter is fluid corrosion, dimension decreases, and lead to flow value is low. And as the spiral vortex flowmeter in body fluid corrosion and reduce the width, face flow plane surface become rough, causing flow coefficient change. c。 Shorten the life of instrument. Such as metal tube rotameter in tapered tube parts and components, such as using a few years later, the welds are rotten. d。 Leakage of corrosive medium, such as not timely detection, timely treatment, also easily lead to safety and accidents. 3, measures of corrosion on the flow measurement of fluid a and replaced periodically instrument on metal corrosion, resistance to corrosion medium is varied. Some corrosion speed, namely general corrosion, some corrosion is slight, speed is slow, the local corrosion. On instrument selection should be according to particular case is particular analysis, and then make a decision. B, the brief.

For more flowmeter manufacturers to choose models and price quotations, you are welcome to inquire. The following is the details of the analysis article on the dual-frequency non-interference switching system of circulating fluidized bed boiler fans. 0 Introduction With the“Twelve Five”The Comprehensive Work Plan for Energy Conservation and Emission Reduction has been carried out in depth, and my country's electric power, steel and other industries have strictly followed the“Adhere to the combination of reducing energy consumption intensity, rationally controlling the total energy consumption, and promoting technological progress to greatly improve energy utilization efficiency”policy guidelines, and actively implement energy conservation and emission reduction measures to contribute to sustainable development. Shandong Weihai Botong Thermal Power Co., Ltd., as the main heating unit of Weihai Economic and Technological Development Zone, provides steam for production and undertakes the central heating task of nearly 5 million square meters for more than 130 enterprises and institutions in the area. The company has two 130t/h and one 220t/h boilers as the main boilers, which undertake most of the heating and heating tasks. However, due to the shortcomings of the traditional design scheme, relying on the wind baffle to adjust the wind pressure leads to a large amount of energy consumption and a serious waste. In order to actively respond to the call of national policies and improve comprehensive economic benefits, Shandong Weihai Botong Thermal Power Co., Ltd. has carried out frequency conversion and speed regulation transformation of fans. 1. Necessity of the reformation of the flue gas fan system of the circulating fluidized bed boiler First of all, the speed regulation operation of the fan was not considered in the initial stage of the boiler investment. The fan runs at a constant speed, and the wind pressure is completely adjusted by the air baffle. The adjustment and control characteristics of the baffle are poor, and the pressure loss is serious. The baffle is open at 30%~80% for a long time, and the system efficiency is low, resulting in high power consumption in the plant. The power consumption of 130t/h furnace ton of steam reaches 9~10kWh/t, and the power consumption of 220t/h ton of steam reaches 11~12kWh/t, resulting in a great waste of energy. Secondly, the traditionally designed primary fan, secondary fan and induced draft fan use the opening of the inlet restrictor (or baffle, damper) to adjust the pressure. Since the general design air volume and air pressure are required to have a larger design margin than the rated operating conditions, the general fan and motor selection are too large, so the actual air door opening is 30%~80%, resulting in the fan often working at a low efficient area, wasting a lot of energy. Thirdly, the linearity of the air volume adjusted by the damper is not good. When adjusting the damper opening, it often occurs that the opening degree changes little but the air volume changes greatly. It is difficult to achieve the automatic combustion required by the precise air volume ratio, which affects the circulating fluidized bed. The operating efficiency of the boiler. Therefore, the application of frequency conversion speed regulation equipment to the fan of the circulating fluidized bed boiler can reduce the power consumption rate of the unit, and due to the excellent characteristics of the frequency converter speed regulation, its application can lay the equipment foundation for the automatic control of the boiler unit. In terms of energy saving and operation management, the operating cost of the unit is reduced. 2. Energy-saving principle of high-voltage frequency converter speed regulation technology The frequency conversion speed regulation of asynchronous motors is achieved by changing the synchronous speed by changing the stator power supply frequency f. In the speed regulation, a small slip rate can be maintained from high speed to low speed. Therefore, the consumption of slip power is small and the efficiency is high, which is the most reasonable speed regulation method for asynchronous motors. It can be seen from the formula n=60f/p(1-s) that if the power supply frequency f is changed uniformly, the running speed n of the motor can be changed smoothly. Variable frequency speed regulation of asynchronous motors has the advantages of wide speed regulation range, high smoothness and hard mechanical characteristics. At present, variable frequency speed regulation has become the most important speed regulation method of asynchronous motors, and has been widely used in many fields. For centrifugal fans, the fluid mechanics has the following principles: the output air volume Q is proportional to the speed n; the output pressure H is proportional to the square of the speed n; the output shaft power P is proportional to the cube of the speed n. Namely: Q1/Q2=n1/n2; H1/H2=(n1/n2)2; P1/P2=(n1/n2)3. When the air volume of the fan needs to be changed, such as adjusting the opening of the damper, a large amount of electric energy will be consumed in vain on the resistance of the valve and the pipeline system. If the frequency conversion speed regulation is used to adjust the air volume, the shaft power can be greatly reduced with the decrease of the flow. In frequency conversion speed regulation, when the fan is lower than the rated speed, the theoretical power saving is: E=(1-(n′/n) 3)×P×T where: n is the rated speed, n′is the actual speed, P is the motor power at the rated speed, and T is the working time. It can be seen that the transformation of the fan by frequency conversion not only saves energy, but also greatly improves the operating performance of the equipment. The above formula provides a theoretical basis for frequency conversion energy saving. 3 Implementation plan for the technical transformation of dual-frequency non-disturbance switching of boiler fans Since the three boilers of Shandong Weihai Botong Thermal Power Co., Ltd. are all single fans, that is, each boiler is an induced draft fan, a primary fan, and a secondary fan, and there is no backup. The outage of any fan will cause the shutdown of the boiler. In order to avoid the normal operation of the boiler due to the unstable operation of the inverter, the boiler DCS system was reconfigured and seamlessly connected with the inverter. After many cold and hot state tests, the boiler DCS system was combined with the high-voltage inverter. Together, the function of automatic two-way switching between frequency conversion and power frequency is realized, and the non-disturbing switching is truly realized.

Overview The level parameter of the new dry process cement production line is one of the main measurement parameters for production control. With the improvement of the automation level of cement production and the reliability requirements of the control system, the role of material level measurement and control is becoming more and more prominent, which plays a very important role in production control and management. There are many methods for level detection, such as contact type, non-contact type, limit type, continuous type, 3D level detection, etc. The level measurement of the cement production line is mainly based on solid level measurement, and there is also a small amount of liquid level measurement. The solid materials are mainly block materials, granular materials and powder materials. The dielectric constant, bulk density, temperature and moisture content of these materials are different, and the requirements for measuring instruments are also different. With the development of level measurement instrument technology, the past measurement methods such as contact type and limit type have been seldom used in production control. In the new cement production line, the level measuring instruments are mainly radar level gauges. Features of Radar Level Gauge Radar level gauges began to be used in the late 1990s. The microwave frequency range is 300MHz to 300GHz, and the propagation speed is the speed of light. The microwave penetrating power is strong, the transmission speed is not affected by dust, steam and medium components, and the transmission attenuation is also small. The radar level gauge uses the principle of echo ranging. The transmitting antenna transmits microwaves to the measured target, and the microwaves reflected by the measured target are received by the receiving antenna, and the signal processor compares the transmitted signal with the received signal to calculate the measured distance. Since the microwave has attenuation and interference reflection on the propagation path, the key to the measurement is to be able to receive the reflected echo and identify the effective echo. The received echo energy is related to the transmitting and receiving efficiency of the antenna and the radiation power of the antenna, so the antenna design and shape of the radar level gauge are critical. The received echo energy is related to the dielectric properties of the material surface. The higher the dielectric constant value ε, the higher the reflectivity, and the higher the echo intensity. When the dielectric constant value ε is low, the material will absorb part of the microwave energy, and the echo intensity is also low. Usually the dielectric constant value ε of the material to be tested is required: liquid is ε>1.8, solid ε>2.5. Cement plant solid dielectric constant value ε>2.5, the dielectric constant value ε of cement is 3. Radar level gauges are usually divided into two categories: pulse radar (Pulse) and frequency modulated continuous wave radar (FMCW). Process monitoring occasions mainly use pulse radar level gauges. The currently used pulse radar level gauges are divided into low frequency and high frequency. Compared with the low-frequency pulse radar level gauge, the high-frequency pulse radar level gauge has the following advantages: high energy, small beam angle, small antenna size, and high precision. However, low-frequency radar has low energy and scattered energy, so the launch angle is large and the directivity is poor. The wavelength of 26GHz radar is 11mm, and the wavelength of 6GHz radar is 50mm. When the radar level gauge measures the material level, the radar wave reflection mainly comes from the diffuse reflection of the material surface. The intensity of the diffuse reflection is proportional to the size of the material and inversely proportional to the wavelength. 3 Selection of Radar Level Meter In cement factories, limestone silos, gypsum silos, etc. to store bulk materials, clinker silos to store granular materials, raw meal homogenization silos, cement silos, carbide slag silos, etc. to store powdery materials. The stored materials are different, and the selected instruments are also different. When used to measure the storage body level of bulk materials and granular materials, because these materials are densely packed in the storage, the dielectric constant is stable, and the microwave reflection intensity is high. The dust generated by solid materials during the feeding process is much smaller than that of powder materials, and has little effect on the attenuation of radar acoustic signals. According to the material repose angle and surface conditions formed by feeding and unloading, after determining the effective range, a radar level gauge with a rod or horn antenna is used.

The gas mass flowmeter consists of a gas flow quality sensor and a digital display integrator. The gas mass flowmeter adopts the American Microbridge gas flow mass sensor and pressure sensor. The airflow quality sensor is based on the heat transfer principle that the heat taken away by the airflow quality flowing through the sensor is proportional to its output voltage. The pressure sensor is that the pressure of the gas is proportional to the output voltage, that is, the gas mass flow and gas pressure are simultaneously converted into analog signal output. The function of the digital display integrator is to convert the airflow quality analog electrical signal output by the airflow quality sensor into a digital signal through the A/D inside the single-chip microcomputer. After calculation and processing, the mass flow rate of the gas is converted into the corresponding volume flow rate under the standard state or the mass flow rate under the standard state. After data processing and calculation, the real-time flow and cumulative flow are calculated respectively, and sent to four-digit and eight-digit digital tubes for display. The volume of fluid is a function of fluid temperature and pressure, and is a dependent variable, while the quality of fluid is a quantity that does not change with time, space temperature, and pressure. As mentioned above, the flow measurement values ​​of commonly used flowmeters, such as orifice flowmeters, turbine flowmeters, vortex flowmeters, electromagnetic flowmeters, rotor flowmeters, ultrasonic flowmeters and oval gear flowmeters, are fluid volume flow. The amount of fluid involved in activities such as scientific research, production process control, quality management, economic accounting, and trade transfer is generally mostly quality. Measuring only the volumetric flow rate of the fluid by using the above-mentioned flowmeter often cannot meet people's requirements, and it is usually necessary to try to obtain the mass flow rate of the fluid. In the past, the quality of the fluid could only be obtained indirectly through methods such as correction, conversion, and compensation after measuring the parameters of the fluid such as temperature, pressure, density, and volume.
