Chemical pump leak-free is the eternal pursuit of chemical equipment, it is this requirement contributed to the growing use of magnetic pumps and shielded pumps. However, there is still a long way to go without leakage, such as the life span of the magnetic pump isolation sleeve and shielding pump shielding sleeve, the material pitting problem, the reliability of static sealing, and the like. Chemical pump is often transported corrosive, or toxic volatile media, so the sealing performance is to measure the chemical pump is good or bad one of the criteria. In the choice of chemical pumps, should refer to the following criteria. 1, the seal has a static seal and dynamic seal points. For the static seal, usually only the seal and seal two seal forms, and in the O-ring seal again the most widely used; for the dynamic seal, rarely used packing seal, which is mainly mechanical seal as Lord, and the mechanical seal is divided into single-ended and double-ended, balanced and unbalanced. Balanced type which is more suitable for high pressure medium seal, which usually refers to the pressure greater than 1.0MPA. The double-sided machine seal is mainly used for high temperature, easy crystallization, viscosity, containing particles and toxic volatile media, double-ended machine seal should be injected into the sealed chamber isolation fluid, the pressure is generally higher than the medium pressure 0.07 ~ 0.1MPA . 2, sealing material. Chemical pump static sealing materials usually use fluoroelastomer material, in special circumstances will use PTFE material; mechanical seal ring material to be careful, not all are selected carbide like. If all choose cemented carbide, then the price will be high. The general situation is static ring hard, moving ring soft. Such as silicon carbide and graphite. Relatively affordable, only in special high temperature, and the media in the case of particles, static and dynamic ring to use hard to hard materials. It should be as the case may be. Chemical pumps are widely used in various fields of the chemical industry. At present, the chemical pumps produced by domestic manufacturers include: IH stainless steel chemical pump, IHF fluorine plastic chemical pump, FSB fluorine plastic chemical pump, CQB chemical magnetic pump, CQ chemical magnetic force Pump, FZB chemical self-priming pump. These chemical pumps are widely used in chemical, metallurgical, pharmaceutical, foil and other industries, have important uses.
Disperse Blue series include disperse blue 354, Disperse Blue 366, Disperse Blue 165, Disperse Cyanine Blue B, Disperse Blue 3, disperse blue 14, disperse blue 72 etc. Disperse blue 366 is suitable for polyester high temperature and high pressure and thermosol dyeing. Light greenish blue, suitable for printing and high degree of dyeing.
