Paper Making Chemical Specify The Scope
Oct 24, 2017

Paper industry used in coatings and other batches, intermittent operation of the preparation of chemical measurement. Using three shear beam sensor, dedicated connection module and a balanced circuit board with a dedicated junction box composed of field weighing station. To ensure the stability of the weighing tank, the limit device will be installed. Like paint preparation often used multi-material a scale measurement, Paper Making Chemical feeding weighing using "cumulative method." The components of the material according to the recipe requirements set in advance. In the instrument control began to feed the weighing, to the formula set value, the first feeding end, the instrument clear and back to zero, ready to feed the next kind of material weighing, all materials added, Paper Making Chemical the instrument Returns the "total weight" status.

The whole process is under PLC or DCS control. Paper industry with an electronic scale error range of ± 2 kg, it can only be used for large quantities of materials in the formulation of the measurement, the small component of the material through the flow meter, metering pumps and other equipment with higher precision measurement.

(1) the plane of the sensor must be kept horizontal, Paper Making Chemical the roughness within the specified range; between the sensor elevation error within the specified range;

(2) the sensor can not bear the lateral force or super [Received date: 2011-08-04] set, installed to prohibit oblique hanging, twisted, the selected hanging point should be kept level; Paper Making Chemical screw to withstand the sensor arm, should be vertical ; Should be installed limit device;

(3) the sensor can not be damp, due to moisture will make the sensor insulation worse, resulting in internal short circuit, performance degradation. In the open air, where the humidity is large, should be installed in the sensor moisture cover;

(4) to prevent the sensor electric breakdown, Paper Making Chemical after the installation of the sensor with a soft connection wire will scale body and device active body shorted to avoid the scale body on the welding work.

The rotor flowmeter is a commonly used flow meter consisting of two components: a tapered tube extending from bottom to top and a rotor placed in a conical tube and movable freely up and down along the centerline of the tube. When the fluid flow is measured, the measured fluid flows from the lower end of the cone, Paper Making Chemical and the flow of the fluid impinges on the rotor and produces a force on it. When the flow is large enough, the force acts to hold the rotor and lift it up high. At the same time, the measured fluid flows through the annular cross section between the rotor and the tapered tube wall and flows from the upper end. When the measured fluid flow on the rotor force, just equal to the weight of the rotor in the fluid (called the display weight), Paper Making Chemical the rotor force is in balance and stay at a certain height. Paper Making Chemical The position height of the rotor in the conical tube has a corresponding relationship with the flow rate passing therethrough. Therefore, the corresponding flow rate value can be obtained by observing the position height of the rotor in the conical tube.
