The trap is based on the medium pressure, displacement, back pressure and many other factors to choose the suitable product, the trap must be selected, not expensive. The trap is an energy-saving valve product, so the choice of a trap, especially a high-quality steam trap to save energy and improve production efficiency will be several times the cost of purchasing a trap. Here, we will analyze the selection of traps for pipes of different media, but which type and size of traps should be used depends on the calculation of specific parameters. For the selection of steam traps, high sensitivity, accurate and unobstructed steam and drainage, no leakage of steam, improved steam utilization, reliable working performance, high back pressure rate, long service life and convenient maintenance are the preferred conditions. 1. In the production process of heat exchange equipment, drying room, rapid heat exchanger, distillation equipment, etc. need to rapidly heat up, do not allow the production of heating equipment with condensed water, should use mechanical traps. Mechanical traps are not affected by changes in operating temperature and pressure. Water is discharged, and the degree of subcooling is small. There is no water in the heating equipment, which can make the heating equipment reach the working temperature. Among them, the structure of the free float type steam trap is advanced and very sensitive. The small degree of subcooling of the Zui is 0 °C, and it can discharge the saturated temperature condensed water without steam leakage. The advantages are many, which can make the heating equipment reach the work efficiency. It is the ideal steam trap for the production process heating equipment. 2. In steam pipelines, heat tracing pipelines, small heating equipment, heating equipment, and steam equipment with low temperature requirements, thermostatic traps should be used. The thermostatic trap has a large degree of subcooling and a low condensing water temperature, which can fully utilize the sensible heat of the high temperature condensed water, and the energy saving effect is good. Among them, the structure of the membrane type steam trap is advanced, no manual adjustment is required, and it is very sensitive. The two membrane cassettes of 15°C and 30°C are available for selection. They are not afraid of freezing, small in size, and can be installed at any position. It can repair and replace the valve core on the pipeline, saves money and labor, has long service life and wide application range. It is a boutique of thermostatic steam traps. 3. On high temperature and high pressure superheated steam lines and equipment, special steam traps for superheated steam should be used. The superheated steam trap can separate the high temperature condensed water generated when the superheated steam disappears under the severe conditions of high temperature, high pressure and small load. The disc type steam heat preservation type steam trap uses the pipeline steam to heat the main steam chamber of the steam trap, and has an advanced structure. In the case of no condensed water, the steam trap is tightly closed, the working quality is high, the service life is long, and the high pressure is overheated. Steam special trap.
Additives mainly refer to various antibiotics, antioxidants, mold inhibitors, binders, colorants, flavouring agents, health care and metabolic regulation drugs, etc. are conducive to enhancing feeding effect, conducive to the production and storage of non-nutritive Feed Additives and their formulated products. It is mainly divided into food additives, feed additives, concrete additives, and oil additives.
Food additives refer to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are a term that refers to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are generally not food and may not have nutritional value, but they must conform to the above definition, that is, they do not affect the nutritional value of food, and can prevent food spoilage, enhance food sensory properties or improve food quality.
Feed additives, also known as feed additives, refer to the general term of additives manually added to formula feed in order to make up for the shortcomings of formula feed and some special needs. The functions of additives include: 1) insufficient nutrients in feed; 2) preventing deterioration of feed quality; 3) improving palatability of feed and utilization rate of feed; 4) enhancing disease resistance of feeding animals, promoting normal development and accelerating growth and production of feeding animals; and 5) increasing the output and quality of feeding animal products. The dosage of these special substances is very small, generally according to a few percent of the formula feed to several parts per million (mg/kg), but the effect is very significant. According to some data at home and abroad, it is considered that the average efficiency can be increased by 5%-7%, sometimes up to 10%-15%.
