Structure and special

The upper and lower flange of the feed valve shell has two types, the circular flange and the square flange, so as to be convenient for users to match. The transmission type has the direct connection type and the chain wheel, the chain wheel type is the side connection type, its structure is compact, the appearance is beautiful. Seal between the right end of the cover and the impeller shaft for the company's advanced technology to ensure reliable sealing, no leakage. Pressure balancing device can be provided according to the pressure requirements of the upper and lower chamber. The utility model has the advantages of easy arch and easy to stick material, and the arch breaking device and the glue removing and cleaning device can be adopted. Impeller with "one" "V" "U" and other forms, according to specific requirements for targeted selection. According to the type is divided into standard type, high pressure, wear resistant, lining type, card type, cleaning type. Different materials can be selected according to different requirements, such as cast iron, cast steel, cast aluminum, carbon steel, 304, 316, 316L, etc.. Can be equipped with speed reducer or explosion-proof motor to meet the explosion-proof requirements of the occasion. Bearing chamber (both sides) can be equipped with air tight seal cover, to ensure that the bearing is filled with high pressure air, so that the material can not enter, improve the reliability of use. The blade end can be provided with a wear resistant sealing strip, which is used to further improve the locking effect. Can be used to improve the wear resistance of chromium or nitriding treatment. The rigid structure of the shell is designed. The main parts are precision casting. The leakage gas balance is set up to improve the transmission efficiency. Can use a special form of shaft seal structure to ensure the reliability of shaft seal. Can easily configure the sensor.
