Compressor interlock logic
Thread Content
There are several conditions that must be met before starting our compressor: the lubricating oil pressure must be normal, the dispatch switch must indicate an active status, the shut-off valves at the compressor’s inlet and outlet must be open, and the button for confirming compressor startup must also be in the proper position – only then can the compressor be started. In SIS, this also has interlocks, and it can be operated in automatic or manual mode. By \"automatic,\" I mean that driving is not allowed if the conditions are not met. What I want to ask is: if this circuit is bypassed, can one still drive even when the conditions are not satisfied?
The compressor lubrication oil pressure is abnormal – do you dare to start the compressor? ? ? ?
On our end, the lubricating oil pressure of the reciprocating machine is above 0.2 MPa, and the oil temperature is above 10°C, which allows the machine to operate
It’s possible to cut it off as a bypass; we’ve tried it before!
Generally, if the conditions for operating a particular chain parking system are not met at startup, a bypass is used; systems that are allowed to start should not use such a bypass.
If it’s not allowed, then why are there automatic and manual settings?
You’ll need to ask your designers about this; we use it during the debugging of sequential logic, and accessing the bypass route requires certain permissions
Logically speaking, it is possible
It’s possible after bypassing, but some chains that use bypassing are simply seeking disaster~~~~
