The first intelligent variable seeding, fertilization, rotary tillage machine Shanghai came out
ZKB series oil-gas recovery vacuum pump is a relatively consummate pump
for oil-gas recovery, working under the ambient temperature at -40~60°C.
It can be used separately or as a part of oil-gas recovery system in
gas stations, which is mainly used for oil-gas recovery, to reduce
pollution and save energy. ZKB Oil-gas Recovery Vacuum Pump Oil-Gas Recovery Pump, ZKB Series Oil-Gas Recovery Pump, Gasoline Vapor Recovery Vacuum Pump Shanghai Jiasong Machine Co., Ltd , http://www.fuel-dispenser-parts.com
China's first intelligent variable seeding, fertilizing and rotary tillage compound machine with independent intellectual property rights was successfully developed by the School of Mechanical Power of Shanghai Jiaotong University and put into use in Shanghai Songjiang Fuxin Farm. Its advent marks that China's digital agricultural technology has reached the world's advanced level.
According to the introduction, GSP-based intelligent variable seeding, fertilization and rotary tillage compound machine can scientifically analyze the farmland soil condition by electronic information technology, and then scientifically carry out precise variable fertilization and sowing according to the data analysis results, which can greatly save the seed fertilizer. The amount of use and the reduction of agricultural inputs will not only increase the planting benefits, but also help protect the ecological environment.
For agricultural countries like China, precision agriculture technology is of great significance. Due to the low utilization rate of chemical fertilizers, the annual loss of nitrogen fertilizer in China has reached 13 million tons, equivalent to more than 300 billion yuan. While wasting resources, the damage to the ecological environment is also growing. Such problems are widespread in countries all over the world and have aroused widespread concern in the international community.
Precision agricultural technology has developed rapidly in foreign countries, and the technical system has gradually improved. It has become a frontier research field for the major developed countries to rationally use agricultural resources in the 21st century, improve crop yields, reduce costs, reduce environmental pollution, and improve the competitiveness of agricultural products in the international market.
Professor Liu Chengliang, director of the Institute of Mechanical and Electrical Engineering of Shanghai Jiaotong University, and other scientific research personnel, with the support of the Ministry of Science and Technology and the Ministry of Agriculture, after more than two years of collaborative research, finally developed a machine-electric-liquid-suitable for China's national conditions. "Integrated intelligent composite machine, the project has completely independent intellectual property rights, has applied for 8 patents, and passed the national agricultural machinery testing and identification. Experts believe that this new technology fills a gap in the field of domestic agricultural machinery research.
With the growing requirement on taking
advantage of environmental pollution and energy well, this oil-gas
recovery vacuum pump will be applied to this field widely.
Structural Characteristic
Characteristic
of ZKB series oil-gas recovery vacuum pump: a shaft drived by motor is
fixed on the pump body, and its one end in the pump body is fixedly
connected a crank which is jointed to a connection rod; a piston in
liner with reciprocating motion is fixed on the top of the connection
rod, and the liner is fixed in the pump body; a valve seat assy above
the piston has inlet valve and outlet valve which are check valves.
Besides, the inlet cavity and outlet cavity on the pump body are
connected with the inlet valve and outlet valve respectively; through a
pipeline, the inlet cavity is connected with the coupling of an air
eliminator, and one end of the coupling is connected with the hose
through the hose coupling; the hose with internal and external casing is
connected with nozzle.
