What is the interlock pressure switch, what is its principle of action

Answer:

The interlocking system includes a driving system and a parking system. Driving system refers to the conditions before and during driving, such as the compressor oil system is not normal can not start the host, the furnace fuel gas pressure is not normal do not have the reset conditions. These are essentially locking the system or called the system to prevent trouble, is the driving condition. The parking system is in the event of failure, the use of interlock protection system to stop some of the equipment, or to make some equipment, valves (opening and closing). The importance of the interlocking parking system is much greater than the driving system. Interlocking system is essentially an automatic control system, the interlocking content can generally be divided into four areas: 1, due to process parameters of a system limit (interlock value) caused by interlocking action, referred to as "process parameters interlock " Such as heating furnace parking system. 2, transfer equipment itself or between the unit interlock, known as the "unit interlock." Such as catalytic hull parking system. 3, the program interlock. Can control the operation of the process equipment according to certain procedure or time order. Such as switching of the PSA unit heat exchanger. 4, with the start of the unit interlock, that is, stand-alone open parking.
