Drought disaster is one of the most serious natural disasters in agricultural production. In recent years, with the continuous changes in the climate, the area of ​​agricultural disasters has also been expanding year by year, and the frequency of occurrence has been gradually accelerating. Therefore, the monitoring of soil moisture and drought conditions using soil drought monitoring systems is imperative. Row. The use of the soil drought monitoring system to organize the implementation of soil moisture and drought monitoring work has important practical significance for realizing stable grain production and increasing farmers' income this year; it has a profound impact on improving water use efficiency and achieving sustainable agricultural development.
The application of soil drought monitoring system can realize scientific agricultural irrigation and optimize irrigation management according to the characteristics of unused areas. The use of soil drought monitoring system for scientific irrigation needs to be divided into the following three steps.
1. Collect Soil Moisture Data Soil moisture data is the basis for agricultural science irrigation. Therefore, the first step is to use soil drought monitoring system to collect soil moisture data. The system can automatically collect soil moisture data in real time or regularly, and the corresponding The data is sent to the control center for comprehensive analysis and summary, and the soil moisture content under different terrains, different ground forces, different soils, different crops, and different irrigation levels is collected, and the parameters such as irrigation quantity and irrigation time are determined accordingly.
2. Formulating irrigation schemes According to the monitoring data of the soil drought monitoring system, agricultural technicians can determine the irrigation schemes for different regions and different crops based on the crop water requirement law, soil water supply performance, and effective precipitation data, and provide the superior leadership decision-making. Scientific basis.
3. Popularizing Scientific Irrigation Knowledge Currently, many regions carry out agricultural irrigation or experience irrigation. Therefore, to further implement the scientific concept of development, it is necessary to popularize scientific irrigation knowledge to farmers' friends and further expand the use of soil drought monitoring systems. In the form of field guidance, technical training was conducted to transfer scientific irrigation knowledge to millions of households.
Chemical Liquid Truck
Chemical liquid truck is widely used in loading and unloading of acid, alkali, salt and other corrosive, medium risk. Chemical liquid transport tanks material could be selected according to the need of carbon steel, carbon steel lined with plastic, stainless steel, plastic cans, cans, etc.
The structure
Chemical liquid truck by the second class chassis, chemical liquid truck tanks, chemical pump and other parts
After the man build chemical liquid truck
classification
According to the transport medium
According to the different kinds of chemical liquid truck transport medium are: hydrochloric acid transporter, transporter of sulfuric acid, hydrofluoric acid transporter formic acid transporter, acetate (glacial acetic acid) transporter, hydrogen peroxide (h2o2) transporter, transporter phosphate, ammonia transporter, transporter, sodium hydroxide solution, potassium hydroxide transporter sodium hypochlorite (bleach water) transporter, transporter, formaldehyde ethanol transporter, toluene transporter, transporter, xylene isopropyl alcohol transporter, dimethylamine easy transporter, naphtha (solvent oil) transporter. According to these transport medium is different, the material is different also, according to different materials, the chemical industry is divided into carbon steel, stainless steel car, car all steel lining plastic car, car all plastic, aluminum and aluminum alloy and so on
According to the shape
Pointed chemical liquid truck, flat chemical liquid truck, small three axis after chemical liquid truck, build chemical liquid truck, after the first four eight chemical liquid truck, etc
According to the chassis
Dongfeng, liberation, Europe mann, steyr type chemical liquid truck, etc
According to the emission standard
Five, four, three, the two nations
CLW GROUP TRUCK Chemical liquid tank truck Special parts
1, tanks can choose material: carbon steel lined with plastic or stainless steel plate.
2, pot body shape: oval, square shape, round.
4, chemical pump: use domestic famous enterprises special chemical liquid pump with high quality.
5, function: can be independent or warehouse, packing different chemicals, liquid food.
6, set inside the multichannel all plastic wave plate. Comprehensive by high-pressure gas tightness test, high intensity of tank, the center of gravity, vehicle transport safety smoothly.
Tank production standard
1. The tank is wisco carbon steel 6-8 mm thick high quality steel or high quality stainless steel manufacturing according to international standards.
2. Vats with advanced welding technology, try to form high pressure gas after molding leak detection of tank, the tank has high strength, stable center of gravity, smooth vehicles carrying security etc.
3. Tanks after welding using blasting pretreatment process, realize the rust removing rust, appearance is beautiful and durable.
Security considerations
High chemical liquid truck is belong to dangerous goods transport vehicle types, through baidu encyclopedia, although we can know about the chemical liquid truck overview, structure composition and the material requirements, but few of them know what are the specific harm, should be how to prevent in driving at ordinary times? Here, the detailed explanation for everyone:
CLW GROUP TRUCK Chemical liquid truck is mainly with explosive, flammable, toxic, corrosive and radioactive hazard, the safety of the people have a certain potential hazards, complete the transportation task is a strong and professional technical work, taken in the process of transportation, can cause serious loss of life, property and environment.
Security considerations, the first is must have the qualification of dangerous goods transportation driver and supercargo; The second vehicle safety status and safety properties qualified; In the third when loading the goods should pay attention to details; The fourth driving carefully, smooth driving, driving the attendance check, choose proper route, driving time properly; The fifth careful unloading, prevent pollution; Emergency treatment well-prepared.
