1. The high-viscosity rotor pump can only be operated under pressure, flow rate, viscosity, temperature, PH value, solid content and other conditions when selecting and ordering in principle. As far as possible, it can avoid running under the condition of exceeding the limit . 2. High-viscosity rotor pump material viscosity, flow, pressure increases easily lead to motor overload, pressure gauges should always check the safety valve, over-current protection device is normal. 3. High-viscosity rotor pump equipped with insulation device pump, should be turned on before the hot water (steam) preheating until the pump temperature rose to the delivery process requirements start. Stop the pump and then turn off the hot water (steam) before shutting down. 4. High-viscosity rotor pump equipped with mechanical cooling water seal, turn on the cooling water before starting, open the pump, and often observe the cooling water is normal, non-cooling water is running. 5 high-viscosity rotor pump should be cleaned within one year after the filter, filter, to avoid obstruction, resulting in the pump can not be normal operation. Try to avoid using Y-type pipe filter (Y-type pipe filter effective area is too small, affecting the feed medium flow rate, resulting in pump vibration). 6. High-viscosity rotor pump on the coagulation of high-viscosity medium delivery, the pump should be diluted before the pump medium to prevent residual high viscosity medium pump solidification, if necessary, please use the cleaning fluid through the pump cycle cleaning 5-10 minutes . 7. Conveying after cooling will condense the condensed medium, the operation should be promptly run with cleaning fluid 5-10 minutes to clean the lumen. Need to be replaced several times cleaning fluid, and extend the cleaning time. 8. The newly installed pipeline, you must remove the pipe slag, hard particulate foreign body, to avoid the use of free access to the pump chamber, damage to the rotor, the pump, the main shaft, mechanical seals and so on. 9. Regularly check the connection, fastening screws are loose, if any, please fasten. 10. Always check gearbox oil mirror, such as no oil surface visualization, you need to refuel, refueling amount to half of the oil mirror shall prevail. 11. If the conveying medium contains a small amount of metal impurities, magnetic filters should be installed before the inlet pipe.
