By tests to determine the lining thickness δ≥2mm more appropriate. And with the increased diameter of the pump to increase the density of fluorine plastic should be used in about 2.16g / cm3, and does not allow the presence of impurities in raw materials. Lining material for food, medicine, sanitary valves, fluorine plastic chemical pumps, but also non-toxic, sterile, no impurities clean material. Surface fluorine plastic valves should be smooth, without pores, cracks, inclusions and other defects. Flange at the flange and the other at the corner should be uniform color, no whitening phenomenon. Large-diameter welded steel fluorine plastic centrifugal pump can be used the way, the welding point in line with GB / T150 standards. The internal shape of fluorine plastic centrifugal pump should be as simple and lined chemical pumps, easy liner and mold making, chemical pump mechanical seal housing by lining should be smooth and should show all of the corner arc transition radius of curvature R ≥2mm. a. fluorine plastic magnetic pump efficiency is lower than that of ordinary centrifugal pump, not less than 30% of the nominal flow rate in flow operation, more taboo idling. b. fluorine plastic magnetic pump due to the wear resistance containment shell material is generally poor, and therefore magnetic pump generally used for conveying solid particles of medium and magnetic particles into the pump (except for special material is strictly prohibited. c. The general structure of fluorine plastic magnetic pumps, chemical pumps, allowing the transmission fluid diameter of less than 0.15mm, the mass fraction of not more than 5 percent of solid particles containing (need to add auxiliary systems over). d. between the pump and motor are connected by a coupling, the coupling installation requirements for high precision, no time, will lead to the entrance of bearing damage and anti-wear single leak containment shell (low-power direct-coupled pumps are available). chemical pumps, IHF200-150-250A, nitric acid pump chemical provided by the Shijiazhuang-pump Pump Co. faction. chemical pumps, IHF200-150-250A, nitric acid pump chemical pump Pump Co., Ltd. Shijiazhuang-faction (www.shipaipump.com) this year introduced a new upgrade, the above picture is for reference Please call the telephone or pictures on this page, for the latest information, Contact: Manager Xu.
