High viscosity pump used as asphalt insulation pump：
When the high-viscosity asphalt heat preservation pump is working, the increase in material viscosity, flow, and pressure can easily cause the motor to be overloaded. Check whether the pressure gauge, valve, and overcurrent protection device are normal. , High-viscosity asphalt heat preservation pump is equipped with heat preservation device, it should be preheated by hot water (steam) before starting, and start after the pump temperature rises to the requirements of the conveying process. Before shutting down, stop the pump and then turn off the hot water (steam). After conveying the medium that will thicken and condense after cooling, the cleaning fluid should be run for 5-10 minutes in time after the work is completed to clean the inner cavity. It is necessary to change the cleaning fluid several times and extend the cleaning time. Newly installed pipelines, welding slag and hard particles in the pipeline, to avoid entering the pump cavity and damaging the rotor, pump body, main and auxiliary shafts, mechanical seals, etc. Regularly check whether the connections and fastening screws are loose, and if so, please fasten them in time. The high-viscosity asphalt insulation pump can meet the process requirements of the pump under different viscosity by adjusting the gear gap according to the need of viscosity. Frequently check the fuel tank mirror of the high-viscosity asphalt insulation pump. If the oil-free surface is visible, you need to add oil. The amount of fuel added is half of the oil mirror. If the delivery medium of the high-viscosity asphalt pump contains a small amount of metal impurities, it should be Install a magnetic filter before the pipeline.
