QY-30 gas medium lubricated piston pressure gauge Introduction: The Chuangwei QY series high-pressure gas piston pressure gauge adopts gas medium and gas lubrication, using high-purity nitrogen or dry clean gas as the pressure measuring medium, and is used for the calibration of oil pressure instruments and meters. It can be applied in fields such as national defense and military industry, industrial manufacturing, food and pharmaceuticals, and metrological verification. characteristic: 1. The pressure regulator is easy and convenient to apply pressure; The pressurization system adopts a combination of gas booster coarse adjustment and main engine pressure regulator fine adjustment. The pressure regulator handwheel will not move forward or backward due to pressure increase or decrease, saving workspace and making operation more convenient; The pressurization process of the regulator is easy and fast, with a maximum pressure of 70MPa; 2. The piston system is stable and prevents breakage; Anti break rod and anti friction structure ensure piston performance and extend service life; If there is uneven rotational force and significant shaking after the piston floats, the two bearings designed for the piston can effectively prevent the breakage of the piston rod; The upper limit of the piston is limited by bearings, which solves the problem of metal debris generated by friction with the limit screw when the piston reaches the upper limit position and gets stuck. 3. Flexible selection; The range covers a wide range, from 1MPa to 70MPa, meeting the diverse needs of different users. According to the actual usage frequency, users can choose high-purity nitrogen gas or dry and clean air source by themselves. Technical parameters: model: QY-30； QY-40； QY-60； QY-70； Range: including tray: （1 ~ 15）MPa、（2 ~ 30）MPa、（2 ~ 40）MPa、（5 ~ 60）MPa、（5 ~ 70）MPa； Pressure medium: high-purity nitrogen or dry clean gas; Nominal piston area (note: national standard requirement): 0.1cm2, 0.2cm2, 0.5cm2; Minimum resolution (manual weight): 1MPa; Accuracy levels: 0.005, 0.01, 0.02, 0.05; Weight material: non-magnetic stainless steel;
