Faults and Solving Techniques in Observation of Soil Moisture Monitoring System

The observation of soil moisture content in China from the determination of the physical characteristics of soil moisture to the formal operation of the business, the overall situation is good, but some stations also have many problems. Having engaged in this work for a long time, the application of soil moisture monitoring system has encountered many problems in observation operations. Through careful study of the norms, careful analysis of research problems, treatment of similar problems at the consulting station, and continuous processing of emerging problems, we have accumulated some good experiences and methods. The following aspects are discussed in order to help the staff in the operation of the soil moisture monitoring system.

The four duplicate points shall be determined in the four communities according to the provisions of the code. After completing the soil samples required by the soil moisture monitoring system, they shall be marked to provide reference for determining the location of the next drill site. The larger stones encountered in the soil shall be taken out and cannot be placed in the soil box as soil samples. If too many stones affect the representativeness of the soil samples, the drill site shall be selected again. The amount of earth to be taken should be between 40 and 60g. No less, not too much.

Through longitudinal and lateral comparisons, pre-audit and proofreading records of the soil moisture monitoring system. Longitudinal comparison is to analyze the weight water content of each layer from the shallow depth to the deep layer according to the rainfall condition and the soil moisture evaporation status, and see if the change has continuity, if the weight water content value of a repeated layer or layers is too large or too large. Small, should be analyzed with the size and timing of precipitation and moisture evaporation.

After the application of the soil moisture monitoring system is detected and recorded, the soil moisture monitoring report needs to be written. First of all, the standards for soil relative humidity and drought should be well-known. Secondly, the past and future weather should be studied and analyzed in depth. The soil moisture monitoring report has no application value, because if we don't know the weather trend, we don't know the future drought trend. Therefore, the soil moisture monitoring report should be written based on the soil moisture monitoring system data at the monitoring site, the actual drought conditions, and the future weather evolution.

Taper Double-Screw Spiral Mixer

Taper double-screw spiral mixer Overview:

Through revolution and rotation of the screw, the materials make complex movements in the cone, which mainly include the four movement types:

●The screw makes revolution along the walls to make the materials make circumferential movement along the conical walls.

●The screw makes rotation to make the materials rise along the screw from the conical bottom.

●The screw makes revolution and rotation to make some of the materials absorbed into the cylindrical surface of the screw. Under the centrifugal force produced due to rotation of the screw, some of the materials in the cylindrical surface of the screw are discharged radially towards the cone.

●The rising materials fall due to their gravity. The four movements produce convection, shearing and dispersion in the mixer so as to realize the purpose of fast and even mixing.

Application:

It is widely used for mixing, reaction, drying and cooling of powders and powders (solid-solid), powders and liquids (solid-liquid) and liquids and liquids (liquid0liquid) in such industries as chemical industry, medicine, pesticide, dye, petroleum, metallurgy, building materials, etc.
