[Asia Pump Network News] single screw pump suction liquid situation encountered how to deal with? Below, Xiao Bian to tell you the method, mainly in the following situations, as follows. Single screw pump encounter suction liquid situation how to deal with First, as the suction pipe or shaft seal leaks will lead to air is drawn into the single screw pump inside, so that single screw pump will be in the state of air intake, import pipe Can not form a negative pressure so screw pump suction liquid. Approach is to check, repair the pipe, remove debris, adjust the replacement seal. Second, the single screw pump motor reversal will lead to screw pump suction liquid phenomenon, adjust the motor polarity connector on it. Third, the suction of the pulp is too dry, or in the semi-dry state screw pump is not working on the reason the liquid can not be absorbed, this situation can only be diluted or to the feed port to add adequate pulp. Fourth, the liquid viscosity is too high will lead to screw pump suction liquid, if it is the problem of liquid viscosity is too high can only reduce the screw speed and then increase the liquid temperature to reduce the viscosity or use vertical screw pump . Fifth, the use of a single screw pump for a period of time on the liquid is not likely to be caused by damage to the stator and rotor, check the replacement of the new stator or rotor on it. Sixth, the import and export pipe valve is not open or opening enough to open the import and export valves on it. Seven, packing sealed single screw pump may be packing wear, mechanical seal screw pump may damage or wear mechanical seal surface, compress or replace the packing, mechanical seal damage to replace the new mechanical seal on it.
