NYP high viscosity pump installation and commissioning of the need to pay attention
High viscosity pump for the petroleum, chemical , paint , oil , pharmaceuticals , dyes, food and other industries.
Applications include transporting organic acids, fatty acids, alkaline substances, caustic soda , soda water , polymers, soap , shampoo, animal fat , vegetable oil , chocolate and other special fluids.
Let's look at matters NYP high viscosity pump installation should be noted , in addition, we need to debug NYP high viscosity pump to protect it NYP high viscosity pump to work properly.
NYP high viscosity pump flange or abutment should be used with a common drive motor mounting base , foundation or bearing flange having sufficient rigidity is required , to reduce vibration and noise generated during operation of the gear pump . Motor and gear pump shall be connected with a flexible coupling , concentricity of less than 0.1 mm , the tilt angle of not more than 1 degree. Coupling may not be used when installing a hammer to avoid damage gear pump gear and other parts. If using pulleys , sprockets and other drive bays support should be set up to prevent the pinion gear bearing by radial forces. Fastening gear pump, the motor ground screw , screw force should be uniform , reliable connection . When turned by hand couplings, gear pumps should feel able to easily rotate , no clamping or other abnormal phenomena before you can pipe . Suction pipe diameter NYP high viscosity pump should be large enough and avoid sharp bends or narrow passages , reducing elbow, removing unnecessary valves , fittings, pumps reduce mounting height as possible to shorten the length of the suction pipe to reduce the pressure loss. Sealing pipe joints and other components to be good , to prevent air intrusion, thereby controlling cavitation and cavitation occurs.
NYP high viscosity pump before the start of the operation , to the internal gear pump casing filled with the liquid to be transported for safe start. If the ambient temperature is below freezing , the pump should advance to pass into the hot steam , preheating before starting the gear pump. The direction of rotation of the gear pump to the inlet and outlet ports consistent . Gear pumps if the first run , or long-term idle before use , the best start and under no-load or low load conditions Unity hours. If the running-in phase advance notice abnormal temperature, leakage , vibration and noise , you should stop to check .
The check valve and the output valve in the pipeline to install a gear pump is preferably a check valve . So that when access to the pump and the output pipe system liquid back does not occur. Gear pump with a load stop, rewind and also prevent the pump generates a partial vacuum in its output pipe . It should be noted that the outlet check valve is not installed backwards or appear stuck. Export pipeline NYP high viscosity pump should also set a safety valve and other protective devices , so that once the pump outlet passage blocked, you can open the safety valve relief . Safety valve and pump or pump cover can cast one, also can be fitted separately. The need for reversing the NYP high viscosity pump , its import and export pipeline are required to set up a safety valve .
TaiBang production NYP high viscosity pump , high viscosity pump , high viscosity gear pump in the well-known brands, products exported to over 110 countries and regions, ranking the forefront of the quality and quantity of high-grade products. Trustworthy ! ...
