Double Rotation Pulping Concentration Transmitter¹

Product Description  Base weight valveQuantitative control is the key link of papermaking, the quality of material discharge directly affects the quality and pass rate of paper forming paper. The control accuracy of electric material door is one thousandth, can fine- tune the material door, so as to accurately control the quantitative. Electric door repeat accuracy is high, in the paper machine to change different varieties, easy operators will be the door one step to adjust in place, reduce loss of paper / reduce costs. System composition: electric door has electric adjustment quantitative valve and valve controller composition. In a paper mill, it is very important to detect the flow of pulp entering the head box. This flow parameter directly participates in the control of the paper quantification. Due to changes in head box pressure and liquid level, the amount of pulp jetted onto the mesh through the lip plate will fluctuate. Therefore, controlling the stability of the head box pulp flow is vital to the control of the paper basis weight, and it will also directly affect the paper's quality. The final quality.      Through the measurement of the thickness and moisture of the final finished paper, the flow of pulp is controlled, which is called the "quantitative control system", and is usually considered to be the most important part of the paper machine "QCS" system.The measurement of pulp flow usually uses electromagnetic control valve system.Detailed PhotosProduct ParametersBecause of its structural characteristics, it is suitable for the control of related process parameters in the suspension medium containing fibers or small solid particles in papermaking, chemical, metallurgical and other industrial enterprises. It is especially suitable for the pulp in the pulping and papermaking production process. , White water, black liquor, white liquor and other suspended particle fluids and the automatic adjustment of thick and turbid slurry fluid media.System compositionElectric door has electric adjustment quantitative valve and valve controller composition.PrecisionControlled at 1-2 ‰ during fine-tuningMaximum output torque4000N·mWorking power supply220V AC 1Phase,50/60 Hz, ±10%Ball valve sizeDN150RC81 Consistency TransmitterRC81 Consistency Transmitter application and environmental conditionsRC81 concentration sensor has high sensitivity, good anti-vibration performance, and is almost insensitive to slurry flow rate. It can be applied to all aspects of pulp concentration detection and control in papermaking and pulping processes of papermaking enterprises.Ambient temperature 0~60 0CMedium temperature 0~90 0CEnvironmental humidity ≤85%RHExternal magnetic field ≤400A/m (5 Oersted)Dilution water pressure 0.2~0.4MPaVibration amplitude ≤0.05mm frequency ≤25HzSlurry flow rate 0.5~5m/s                                                                        Technical Parameters of RC81 Consistency TransmitterWorking range:better than ±0.005%1~16% concentration (according to measuring components)1~16% concentration (according to measuring components)Measurement accuracy:close to sensitivity under stable conditionsDamping time:1~100SMaximum working pressure:1MPa, 80°CShell:cast aluminumMotor:3-phase 380VAC, 370W, IP54Analog signal output:4~20mA, load 0~750ΩBlade Consistency TransmitterThe BC20 concentration sensor is an embedded system intelligent sensor, the signal is industry standard 4 ~ 20mA and RS-422 output, matching the BC20 converter, BC20 converter built-in Liquid Crystal Display and control unit, the sensor can be fully accurate calibration and operation, can be multi-point and single point calibration, calibration curve LCD. In the measurement of pulp consistency, the shearing force is the most mature.The BC20 concentration sensor actively measures the force signal produced by the shearing pulp suspension, which is converted into an electrical signal by a microprocessor. This method is insensitive to the normal changes of fiber composition, degree of freedom, filler, flow rate and pressure in the pulp suspension. The utility model overcomes the defects that the zero point of the fixed knife type sensor is easy to drift and is greatly influenced by the current velocity, and has a high performance-price ratio.    Technical parameter Measuring principle, using the pulp shearing force to measure. Working range:1.5 ~ 8% concentration The sensitivity : better than ± 0.0075% (under laboratory control) Damping Time :1 ~ 100s Flow rate: 0.5 ~ 5 m/s The repeatability  :better than ± 0.03% of full range (under stable working condition)  Flowmeter Products Description :Flow meters are widely used in the measurement and control of superheated steam,saturated steam,compressed air and general gases (oxygen,nitrogen,hydrogen,natural gas,gas,ete.). water and liquids(such as water,gasoline,alcohol,benzene,ete.)in petroleum,chemical,metallurgy,heat,textile,paper and other industries.Working PrncipleIf a non-streamline vortex generator (blocking fluid)is set in the ftuid,then two regular vortexes will begenerated alternately from both sides of the vortex generator.  Company Profile
