(1) the material of the contact part of the pump and the liquid should be exposed to the corrosion and electrochemical corrosion of the medium.
(2) in the structure should also take into account the impact of the media to prevent corrosion.
(3) with the motor should be based on the different medium to match the different power of the motor. For the viscosity of the acid, but also consider the effect of viscosity on pump performance.
F type corrosion resistant pump has two kinds of structures, the front door and the back door open door. Front door structure in the inspection of the impeller is to check the impeller, remove the suction pipe from the front, and then open the structure of the pump is not required to remove the pipeline. Its main components are: pump body, impeller, pump cover, pump shaft, bracket, etc.. The direction of rotation of the pump, from the motor side to see the counter clockwise direction.
According to different media, different materials can be used F type pump. These different materials of the same type of pump is just different materials, the same performance.
1.F type corrosion resistant pump should pay attention to matters:
(1) the tray in the gland below, to prevent the leakage of the medium to the bracket bracket corrosion.
(2) the sleeve itself corrosion, corrosion and Jianai washers, to avoid leakage into the medium sleeve pump shaft made from corrosion.
(3) the gap of the mouth ring should be larger than that of the pump.
(4) single spring structure is used in the mechanical seal (with tetrafluoroethylene or other plastic), to avoid leakage caused by corrosion of spring.
(5) to avoid operation under the condition of small flow to prevent the liquid temperature, corrosion; when parking should be closed to prevent the leakage of suction valve, medium pump.
Characteristics of 2.FY type liquid pump:
(1) the pump body is immersed in the liquid of the container, the motor is exposed to the upper part of the container, so that the upper part is not corroded by the transmission medium (two parts can be used for different materials).
(2) because the pump is immersed in the liquid, good sealing performance, the use of soft filler, has been to ensure that no leakage.
(3) if the liquid level above the pump body, can not fill the pump or valve installation and startup.
(4) the pump body is in the container, and the area is small.
(5) the structure of the pump is simple and the service life is int.
The pump is suitable for conveying corrosive medium, and can also be used for sulfur recovery device, conveying liquid sulfur and concentrated sulfuric acid, etc.. In addition, there are FS type stainless steel corrosion resistant pump.
Corrosive medium chemical corrosion pump is widely used in chemical, acid, alkali, metallurgy, rare earth, pesticides, dyes, medicine, papermaking, electroplating, electrolysis, pickling, radio, foil, scientific research institutions, national defense industry and other industries transfer any of the concentration of acid and alkali, oil, rare valuable liquid, toxic liquid volatile.
Fluorine plastic corrosion pump manufacturing mainly TCSF fluorine magnetic pump without leakage (plastic), TCF fluorine leakage magnetic pump (liner type), TCBF fluorine magnetic pump, TCGF fluorine insulation high temperature magnetic pump, TCZF fluorine magnetic pump, TICF fluorine lining magnetic pump, TICBF no leakage no leakage of fluorine high temperature magnetic pump (coupling type), TIBF fluorine magnetic pump without leakage insulation (coupling type), TICZF fluorine leakage self-priming magnetic pump, TSF fluorine plastic centrifugal pump (plastic), TIF fluorine international standard centrifugal pump (liner type), TIBF fluorine insulation centrifugal pump TIGF fluorine high temperature centrifugal pumps, TIZF fluorine self-priming centrifugal pump, TLF fluorine pump and TYF fluorine pump etc.
