Selection and application of filling liquid for oil filled and shock proof pressure gauge

Selection and use of filling liquid for oil filled and shock resistant pressure gauge Oil filled and shock resistant pressure gauge is also called oil pressure gauge or shock resistant gauge The shock absorption effect of pressure gauge system is composed of filling liquid in the gauge case, so as to better protect the working life and service condition of pressure gauge The filling liquid of oil filled shock proof pressure gauge is mainly filled with glycerin, silicone oil and glycerin aqueous solution, but glycerin can be divided into vegetable glycerin, medical glycerin, high viscosity and low viscosity The oil filling pressure gauge of Yade instrument adopts imported high concentration 99.5% glycerin of Malaysian coconut brand as filling liquid The brightness of the glycerin is not yellow for two years, while the inferior and cheap glycerin will vaporize at high temperature, turn yellow and thin, as water generally thickens and discolors at low temperature, and is not resistant to low temperature At present, the oil filled pressure gauge produced by Yade instrument has been widely matched with many well-known hydraulic machine tool factories, such as Guangdong forging machine tool factory, Jiangdu forging machine tool factory, Hong Kong Renxing machine factory, Shenyang machine tool factory, etc., and it is produced and processed by many well-known hydraulic parts OEMs Chongqing Chuanyi and Guangdong Shengyi Technology Co., Ltd have designated Yade instrument brand pressure gauge as * product Vibration and pulsation are the reasons for the failure of the pressure gauge Yade instrument then developed a dry non liquid filled shock resistance pressure gauge It has the same performance as the liquid filled pressure gauge, and makes the observation of the instrument easier and the service life of the instrument longer Dongguan Yade Instrument Co., Ltd
