43APG是一种基地式比例——积分调节器,其气源压力为0.14MP_a的压缩空气,输入信号为原油温度,输出信号为0.02～0.10MP_a气压信号,属气动温度调节器.该气动仪表从美国进口,用于从东营到黄岛的原油长输管道上,实现时管输原油温度的自动控制.由于目前国内气动仪表仍广泛用于石油、化工等部门,因此笔者写下这篇维修小经验以供同行们参考.
43APG is a base proportional-integral regulator, the air pressure of 0.14MP_a compressed air, the input signal is the crude oil temperature, the output signal is 0.02 ~ 0.10MP_a pressure signal, which belongs to the pneumatic temperature regulator. The United States imports for the long-distance pipeline from Dongying to Huangdao crude oil pipe to achieve automatic control when the temperature of crude oil pipelines due to the current domestic pneumatic instruments are still widely used in petroleum, chemical and other departments, so I wrote this small maintenance Experience for colleagues for reference.
