The solution to the glass tube thermometer often encounter problems

Instrument and meter industry in China has developed rapidly in recent years, but still can't adapt to the development of the national economy strong demand, enterprises must find out my own shortcomings, can in order to enhance the glass thermometer industry competitiveness in the international market. Domestic glass thermometer USES mostly made pressure precision machinery processing, while abroad with special materials, the comprehensive mechanical properties, wear resistance, corrosion resistance, compressive ability and polishing brightness is better than domestic materials. Domestic glass thermometer manufacturers, different process conditions, the gap is very large. Many manufacturers with less equipment, less investment, a lot of work rely on manual workers, seriously affect the precision and quality of glass thermometer. Glass tube thermometer in terms of its nature belong to tooling, production of qualified products is the ultimate goal. Glass thermometer, general measurement is not allowed to float or cylinder has caused by adsorption of impurities, moreover measured liquid density changes. Try not to let the bucket vaporizing within the media. DN25 tube openings of borehole leakage panel can, only with asphalt felt paper on the package, outside a layer of paint brush stick spun glass cloth, brush and paint again can. Therefore, the quality of the glass tube thermometer industry, the performance inspection on test results. At present some small tube thermometer also belong to the glass tube liquid level, external materials using 304 stainless steel production, can use water, hydraulic oil, engine oil, etc. Higher dielectric adopts 316 stainless steel for corrosion resistance. Glass tube in the thermometer corker is also a very important part of. N3H magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
