How NYP stainless steel inner ring type high viscosity pump installation and test run

high viscosity pump bearing or flange and its drive motor should use common installation basis, foundation, flange or support all needs to have enough rigidity, to reduce the vibration of gear pump is running and noise. Motor and gear pump with elastic shaft coupling, coaxial degree is less than. Mm, Angle shall not be greater than degrees. When installing coupling hammer shall not be used, in order to avoid damage gear and other parts of the gear pump.
if the high viscosity gear pump should be set when using a pulley, sprocket drive bracket support, in case of driving gear bearing by the radial force. Ground screw fastening gear pump, motor, screw force should be uniform, reliable connection. Turn the coupling with the hand, should feel high viscosity pump can be moved easily, and no abnormal phenomenon such as clamping, then can be piping. High viscosity pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp turn, reducing elbow, remove unnecessary pneumatic valves, fittings, as far as possible to reduce the high viscosity pump installation height, shorten the length of the oil suction pipe, in order to reduce the pressure loss.
high viscosity pump pipe joints and other components of the sealing is good, in order to prevent the air intrusion, which control the occurrence of cavitation and cavitation. Before starting operation, to gear pump casing filled with liquid, facilitate safe launch. If the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump. Direction of rotation of the gear pump, oil outlet in accord.
if the first run, high viscosity pump mooring Thai bond or long-term idle before using, had better under the condition of no load or small load to run one hour or so. If in the running-in stage in advance detect abnormal temperature rise, leakage, vibration and noise, should machine inspection.
high viscosity pump outlet pipe road also pneumatic valve shall be set up safety protection device, so that once the clogging pump export channels, to open the safe pneumatic valve pressure relief. For high viscosity pump need positive &negative, import and export all needs to set up the line security pneumatic valve.
