The role of small air separation unit dcs system

The role of small air separation unit dcs system
Grounding is to achieve a low impedance link between the circuit, the Danyun, and the first-class point or the equipotential surface that is used as the common reference point of the signal. The grounding of the dcs system is to ensure that when the signal entering the dcs system, the power supply or the equipment of the dcs system has a problem, the effective grounding system can withstand the overload current and can quickly lead the overload current to the ground.

In the process of operation, especially in the start-up and shutdown of the air separation unit, one-way force should be avoided on the instrument. During the start-up of the equipment, close the high pressure and low pressure valves firstly, then open the balance valve, and then slowly open the high pressure (or low pressure) valve, so that the measured medium can enter the positive (negative) pressure chamber of the transmitter. If the liquid is to be measured, the gas in the positive (negative) pressure chamber should be discharged from the upper vent. If the gas is measured, drain the liquid accumulated in the positive (negative) pressure chamber from the lower drain screw hole. After discharging the gas (liquid), close the balance valve, and then open the valve on the other side. When the equipment is shut down, the high pressure (or low pressure) valve should be closed first, then the balance valve should be opened, and then the valve should be closed on the other side.
