Although both the blast cleanness tester and the seed cleanness tester measure the degree of clarity, there is a great difference in the accuracy of the measurement. The principle of the blast-type cleaner is based on the principle of wind mechanics, because there is a certain difference between the weight of the seeds and the impurities. The power of the wind is used to distinguish the seeds from the impurities. This instrument can For the preliminary test of the seed's clarity. The Seed Clarity Workbench was developed based on the principle of optics. The principle of optical transmission, reflection and amplification was applied, combined with the design of electronic technology and ergonomic principles, which greatly improved the scientific and technological level of the instrument. Make the measurement of the instrument more accurate. It can be used to determine the quality of rice, this will be able to see that the seed clarity table is very helpful in the subtle observation of the seed's clarity, but also through him to observe some of the seed's lesions, because the seed The epidermis can see some tiny seed lesions, so the seed clarity desk has an important position in the test of the seed's clarity.
The cleanliness of seed cleanliness workbench is comparatively user-friendly in design. When seeds are placed on the workbench during operation, the good seeds are separated from the bad seeds by the enlargement principle, and excellent seeds can be placed under the instrument. In the drawer. The blast cleanness meter is based on the size of the seed particles to control the size of the wind, the excellent seeds to the lower layer, and impurities are placed in the bottom of the instrument, when in use, you can use the blast style net The instrument is subjected to a preliminary test and the seed cleanness table is used for fine inspection.
A finned tube is a heat transfer device consisting of many parallel metal fins commonly used for heat dissipation and cooling applications. Finned tubes increase the surface area of the pipe, thus increasing the heat transfer efficiency. Finned tubes are commonly used in applications such as air coolers, automotive radiators, condensers, and evaporators. They are also used in industrial heaters and refrigerators to increase heat transfer surface area and improve efficiency.
Finned tube is a kind of new, wear-resistant, efficient heat exchange material, is a kind of energy-saving heat exchange element, it uses high-frequency power source as heat source, the steel strip, steel pipe heating at the same time, so that the fusion welding together into one, with high heat exchange efficiency, large cooling area, long service life, adapt to a wide range of temperature, high pressure characteristics, it can also be made of a variety of materials, Excellent heat transfer, durability, heat resistance and corrosion resistance. Widely used in waste heat recovery, petrochemical, power plant boiler, economizer, bus, industrial and civil construction heating, refrigeration, medical drying, wood drying, food drying system and other industries.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
