Boiler water softening equipment, automatic water softener equipment, water softening equipment, water softener equipment manufacturers in Xuzhou, automatic regeneration softener, timed automatic regeneration softener, quantitative automatic regeneration of water softener control valve head, Jiangsu softener equipment manufacturers, boiler water softening equipment prices softener is a water treatment process equipment for boiler scale and the introduction of a long, raw water to remove calcium and magnesium ions and cause the boiler element length scale boiler water softening equipment works: As the hardness of the water main consisting of calcium, magnesium formation and representation, it is generally cation exchange resin (softener), the water Ca2 +, Mg2 + (the formation of scale main ingredient) to displace, as in the resin Ca2 +, Mg2 + increases, the resin to remove Ca2 +, Mg2 + efficacy decreased. When the resin to absorb a certain amount of calcium and magnesium ions, it must be the regeneration process is the salt in the salt water rinse tank resin layer, the hardness of the resin ion exchange out in, with the regeneration waste water discharge tank, the resin He resumed soften exchange. Since the hardness of the water main form and said that due to the hardness of water is mainly formed of calcium, magnesium, and represents the principle of the sodium ion exchange softening process is raw water exchange resin sodium cations, the hardness constituents in the water Ca2 +, Mg2 + and the calcium, magnesium resin is exchanged for Na +, Ca2 thereby adsorb water +, Mg2 +, the water is softened. Chemical equation to convert hard water demineralized water: calcium removal: CaCO3 + 2NaCl = CaCl2 + Na2CO3 magnesium removal: MgCO3 + 2NaCl = MgCl2 + Na2CO3 boiler water softening equipment control valve type: <1>, semiautomatic (manual) control valve <2 >, automatic flow control valve <3>, automatic time-of-reason softener valve boiler water softening equipment control excessive hardness analyze the causes of excessive boiler water softening equipment soft water hardness analysis: 1, the sampling port detection softener equipment is qualified but soft water tank hardness exceeded, the reasons causing this phenomenon as follows: A, the regeneration cycle is set too large, or meters - failures that result are not allowed, so that the resin of the failure to regenerate the reproduction, resulting in excessive water into soft water tank. B, the washing time is short, so this should be washed in the washing of the spent brine is part of the heart to the soft water tank. C, water pressure instability caused by salt water tank is too small, too little salt absorption, is inadequate washing, which can be caused by any one of the second regeneration after excessive water hardness, impact of soft water tank water quality. D, the salt in the salt tank rarely, the failure to add, resulting in poor regeneration of a particular effect. E, improper operation, close to the valve in a second regeneration process. The above error can be caused by any one of a large number of short-term excessive water soft water tank, need qualified excessive dilution water softener long before the soft water tank re-compliance. Cause boiler water softening equipment soft water hardness exceeded analysis: 2 sampling port softener equipment in multiple tests, are unqualified, this situation is divided into the newly installed equipment for the first time to test the water softener and the hardness is discussed separately in excessive hardness softener equipment: A, new clothes softener equipment for the first time exceeded the water hardness test reason: a central tube and control valve junction of O-ring seal is not formed, you should check: the length l central tube is enough, if the outer diameter meets the requirements l Forgot mounted O-ring l O-ring is broken on the b center pipe breakage, cracks. c water TDS value and the resin layer height ratio is too big. water TDS value ratio d and the resin exchange capacity is too large. e inlet and outlet reversed. B in reason with soft water softener equipment excessive hardness: the ratio of a water TDS value and the resin layer height or resin exchange capacity is too large. Compared with the initial test new resin water softener equipment for water with TDS values ??more stringent requirements, when the resin layer height of 1.5 meters, with a total hardness of 13mmol / L, water TDS value ≧ 900mg / L, make sure the soft water hardness ≤0.03 mmol / L will be more difficult. b resin poisoning, caused by aging of the resin exchange capacity decreases. Soft water hardness from such causes excessive is a gradual process, not a sudden obviously exceeded. c salt in the salt tank is too small. When the salt water tank normal, but less than the height of the salt water is 1/3 the height of the brine in the salt absorption step is likely to suck in the late unsaturated, leading through the ejector diluted brine concentration is lower than the regeneration requirements impact of regeneration. d salt box in the total amount of water is too small, our experience is that each of the resin tank 100L resin, desired salt water in the tank is about 35-40L, much less than this will lead to regeneration is not sufficient. e suction brine is too slow, in the normal time, can not inhale enough brine for the following reasons: l l low water pressure above and below the water, sediment and other debris clogging serious l waste water hose deformation, bending, and other row triggered l resin layer that restricts waste too many impurities l Brine pipeline leakage point, the air is sucked into the ejector l l a foreign body in the air check valve failure, early closure or blockage l ejector small boiler softening Selection The reason water equipment soft water hardness exceeded analysis: 3, resin tank in the presence of large amounts of gas, the gas may come from the feed water with gas, washing process or slow air check valve closed lax. g unused large grain non-iodized salt. h control valve internal leakage hard: general internal control valve leakage hard, often have soft water intake and waste water outlet at the same time, but for the 64D or 74A series may leak through the hole formed in the ceramic sheet on the move, if it is this intraspecific drain, rinse in a positive position, can be detected by a qualified soft water port, but then transferred to the operating position, soft water hardness exceeded.
