You do not know what to do when operating fluoroplastic centrifugal pumps? Or know some but not very detailed? Here is a more comprehensive summary, hurry up and see it. First of all, the pump test run should meet the following requirements: ①drive the steering should be the same with the pump steering; ② identify the pipeline pump and coaxial pump steering; ③ fixed connections should be no loose, Lubricants specifications and quantity should be consistent with the provisions of equipment and technical documents; ④ pre-lubrication requirements of the site should be pre-lubricated; ⑤ all instrumentation, safety devices should be sensitive, accurate and reliable; ⑥ crank should be flexible, No abnormalities; ⑦ high temperature pump should be preheated before the test run, the temperature should be uniform rise, the temperature rise per hour should not exceed 50 ℃; pump body surface with a working medium import process pipe temperature difference should not exceed 40 ℃; ⑧ set to eliminate the impact of temperature rise of the connection device, set the bypass connection device to provide cooling water. Second, the fluorine plastic centrifugal pump should pay attention to the following points: ①prohibit water-free operation, do not adjust the suction port to reduce the displacement, prohibit the operation of the flow is too low; ② monitoring operation, completely prevent packing box leakage, replacement Fill the box with a new filler; ③ to ensure that the mechanical seal flush water, water-cooled bearings prohibit the use of excessive water flow; ④ do not use too much lubricant; ⑤ inspection according to the recommended cycle. Establish operating records including operating hours, packing adjustments and replacements, adding lubricants and other maintenance measures and times. Record and record pump suction and discharge pressures, flow rate, input power, temperature of wash fluid and bearings, and vibration conditions on a regular basis. ⑥ pump host is relying on the atmospheric pressure will be low water pumping to a height, while the atmospheric pressure can only support about 10.3m of water column, so the pump host to leave the water 12 meters can not work. See here is not found at least one is their usual use of fluoroplastic centrifugal pump did not pay attention to it, that is your harvest, and extend the life of fluoroplastic centrifugal pumps from now on.
