微压气体压力源的操作需要注意什么?

发布时间:2022-01-06 14:32:56   发布人:
先将升降压手柄旋至更外端,检查仪表接口处是否放有密封圈。
First turn the pressure lifting handle to the outermost end and check whether there is a sealing ring at the instrument interface.
连接被检仪表及标准仪表,将排气阀拧紧。
Connect the tested instrument and standard instrument, and tighten the exhaust valve.
顺时针缓缓旋转升降压手柄,压力接近个检定点,然后旋转微
Slowly rotate the pressure lifting handle clockwise, the pressure approaches the first verification point, and then rotate it slightly
调手柄,使压力完全调定在该检定点。
Adjust the handle to fully set the pressure at the verification point.
记录该点的标准与被检的数据。
Record the standard and inspected data at this point.
再次缓缓顺时针旋转升降压手柄,进行第二点的检定。
Rotate the pressure lifting handle slowly clockwise again to verify the second point.

依次升压直到被检仪表的上限(满量程)。
Boost the voltage successively until the upper limit (full range) of the tested instrument.
降压过程的检定:
Verification of depressurization process:
逆时针旋转升降压手柄,压力接近回检过程的个检定点,旋转
Rotate the pressure lifting handle counterclockwise, and the pressure is close to the first verification point in the re inspection process
微调手柄,使压力完全调定在该检定点。
Fine tune the handle to fully set the pressure at the verification point.
记录该点的标准与被检数据。
Record the standard and inspected data of this point.
再次逆时针旋转升降压手柄,进行第二个回程检定点的检定。
Rotate the pressure lifting handle counterclockwise again to verify the second return verification point.
零点检定:回程检定结束时,应将排气阀打开,进行零点检定。
Zero point verification: at the end of return verification, open the exhaust valve for zero point verification.
负压表的检定:
Verification of negative pressure gauge:
负压表检定,应将升降压手柄旋至更里端,然后连接标准与被检
For the verification of negative pressure gauge, turn the pressure lifting handle to the innermost end, and then connect the standard and the tested
仪表,关闭排气阀。逆时针旋转升降压手柄,进行各检定点的检定。
Instrument, close the exhaust valve. Rotate the pressure lifting handle counterclockwise to verify each inspection point.
