FPG-type pipe centrifugal reinforced polypropylene

■ FPG-type reinforced polypropylene pipeline pump Product Overview: FPG-type reinforced polypropylene pipeline pump, using reinforced polypropylene (RPP), an injection molding, high mechanical strength and corrosion resistance can be strong, the media is not in contact with the metal, mechanical seal sealed long life, high efficiency, low price, is an alternative to stainless steel pumps and other non-metallic pumps ideal product. RPP Material: non-polar, non-toxic pollution, anti-acid and alkali salts in general, the working temperature -14 ℃ -80 ℃, widely used in chemical pipelines. ■ FPG-type reinforced polypropylene pipeline pump Model significance: ■ FPG-type reinforced polypropylene pipeline centrifugal pump performance parameters: Model flow m3 / h Head m Speed ??r / min Efficiency% m Suction Importers mm matching motor kW 25 FPG- 11 4 11 2 90 0 46 5 25 × 25 0.55 40 FPG-18 12 18 2 900 54.4 3 6 40 × 40 1.5 50 FPG-22 18 22 2900 5 1.74 6 50 × 50 2.2 40 FPG-25 18 25 2 900 55.63 6 40 × 40 3 50 FPG-28 22 28 2 900 53.6 3 6 50 × 50 4 ■ FPG-type reinforced polypropylene pipeline pump for use: 1, chemical pumps should be used before starting the irrigation pump or vacuum means to make the pump filled with a liquid, non-slip and reverse. 2, plastic pump transmission fluid should be free of sediment, particles and long fiber material, to prevent clogging cause impeller and mechanical seal damage. 3, the proportion of transmission medium pump is more than 1.2 should reprovision motor, so as not to affect the head or burn out the motor. 4 parking off before the discharge pipe valve. In the case of the need to close the inlet pipe intrusion valve, after closing down. ■ FPG-type reinforced polypropylene pipeline pump Maintenance: 1, chemical pumps use for some time, we found that the end face mechanical seal leakage is caused by mechanical seal face wear, adjust ring, tighten loose semicircle of two stainless steel screws, The ring appropriate to move forward unimpeded better. 2, 8-16 hours daily power pumps optimal use. 24 hours of continuous use should be equipped with spare parts, regular maintenance and replacement, the replacement period is usually two to three months to maturity should be inspected, inspected at any time without affecting the continuous operation of production or use. 3, repair methods Naifushibeng: a. Clear pump casing, cover, impeller and outside the dirt impurities washed away after careful examination, no damage can continue to use. b. Clear and flush mechanical seal assembly inside and outside the dirt, impurities, check the seal face wear, abrasion or minor scratches can be used fine sandpaper on a flat metallurgical polishing to smooth and no scars after can continue to use, by grinding can not eliminate Take scars to be replaced. ■ FPG-type reinforced polypropylene pipeline pump disassembly: Direct order of removal plastic pump: Remove eight bolts connected with the pump bracket (with the front cover of the pump needs to remove the front cover with the pump connected to the pump eight bolts) Remove the casing (a stainless steel front cover fastening screw pump impeller shaft and sleeve dismantle connected, go to the impeller shaft with the motor shaft disconnected inverted; loosen the mechanical seal ring on two stainless steel bolts, take Under mechanical seal ring; remove the impeller, remove the static ring gland disassembled.
