1, the physical properties of the device starts running mechanical seals and circulation protection system (1) the need to ensure protection within the circulation system and the mechanical seal chamber (or lubrication box) have sufficient liquid seal (2) must be protected against circulating system is pressurized, then increased the pressure in the autoclave. Reducer (1) When the ambient temperature is below 0oC, measures should be taken before the start of the oil temperature rises above 0oC restart (2) There must be enough oil before starting, the oil should be consistent with the machine instructions for the stirring kettle liquid level in the container must be kept normal position, especially for non-flexible shaft screw below the ribbon blender is a ribbon -LD ribbon screw -LDG conical bottom ribbon -ZLD conical bottom ribbon screw -ZLG Such a slow agitator stirrer, often operating in the laminar flow area, the liquid rises or falls down cycle along an axial helical surface, suitable for high viscosity fluid mixing and heat transfer and other processes. Common Medium viscosity μ <105cP, common speed n = 0.5 ~ 50rpm, v = 2m / s. LD ribbon agitator ribbon stirred tank outside the gallery close to the wall, large diameter propeller stirrer stirring characteristics, strengthen the upper and lower circulating liquid near the tank wall, the heat transfer process is very suitable for high-viscosity liquids. LDG ribbon screw combined, but also has characteristics of screws and ribbon, and strengthen the liquid inside the peripheral circulation, especially for non-Newtonian pseudoplastic and viscoelastic fluid effective. ZLD cone bottom ribbon type, ZLG conical bottom ribbon screw type, which is characterized by a bottom and a conical-shaped bottoms can match, can be designed. Recently developed a new type of curved leaf runoff disk turbine is particularly suitable for a variety of fermentation tank. Promoting the dispersion of the operated stirrer for dispersing gas blender to use more traditional straight blade disk turbine, since the back straight blade attached to a lot of cavitation to reduce pumping capacity - usually in the air. In the high-speed propeller stirrer gas prices, sometimes entire agitator wrapped cavitation, stirred nearly idle, inefficient. According to cavitation theory reveals gas - liquid dispersion mechanism, the development of new curved leaf disc turbine agitator, to overcome the above drawbacks, its curved blade swirl on the back of it reduces, inhibits the formation of air pockets Four Leaf advance stirrer, with good gas - liquid dispersion mixing performance. Curved leaf disc turbine agitator has the following advantages. ① carrier gas capacity is increased, low-speed generic point. ② improve the dispersion and mass transfer performance, Kla can be increased by 20% to 30%. Since the degree of agitation power ventilation so that the decline is smaller than the other impeller, agitator pumping capacity increase.
