为氨专用仪表，用于测量对普通碳钢、合金结构钢、澳氏体类不锈钢及锡铅合金钎焊料无腐蚀作用，非结晶和凝固的氨气、氨液介质的压力。 Ammonia pressure gauge is a special instrument for ammonia. It is used to measure the pressure of non-corrosive, non-crystalline and solidified ammonia gas and ammonia liquid on ordinary carbon steel, alloy structural steel, austenitic stainless steel and tin-lead alloy solder. . Ammonia pressure gauges are mainly used for measuring the pressure of ammonia liquids, gases or their mixtures during the production of fertilizers or other equipment. Can also be used to measure the pressure of various non-corrosive, non-crystalline and non-solidifying media such as ordinary carbon steel and austenitic stainless steel
是以弹性元件为敏感元件，测量并指示高于环境压力的仪表。 The pressure gauge for ammonia uses the elastic element as a sensitive element to measure and indicate the pressure higher than the ambient pressure. However, the pressure gauge will reduce its service life when it is corrosive. How to extend the service life of the pressure gauge will be briefly introduced. 1. If the medium has corrosion on the stainless steel pressure gauge and copper, the buffer tank can be replaced with an isolation tank, and a corrosion-resistant isolation liquid is added. The type of isolation liquid can be selected according to the nature of the measured medium, but it is better to use it for more than half a year without deterioration. 2. Diaphragm pressure gauges can be used. At present, there are molybdenum 2 titanium and tantalum plates. The pressure between the diaphragm and the ballistic tube is transmitted by methyl silicone oil. Pay attention to the permeability of the medium. Fluorine oil can be used as the transfer liquid. Isolation. 3. For general corrosive media, if the stainless steel spring tube can withstand 1 to 2 years of corrosion, it can be used as a pressure gauge for ammonia. When installing, the buffer coil should be replaced with a buffer tank, and the pressure guiding tube should be short to prevent impurities from clogging.
