Software minimum flow stop provision?
Thread Content
A software minimum flow stop provision is included to maintain a minimum flow/pressure to the nozzles. A software-based mechanism to stop flow at low levels? This post was last edited by echommm on 2008-1-16 08:11]
Literally it seems that way, but something feels off; could the original poster provide more background information?
In my opinion, it should be translated as follows: Computer-controlled reduction of flow rate involves maintaining a low flow rate/pressure at the pipe outlet/nozzle.
I think \"provision\" here refers to equipment and facilities. And minimum means the smallest value; it should not be translated simply as ‘small’.
A software-based minimum flow stop mechanism is included to ensure that a minimum flow/pressure is maintained at the nozzles. This mechanism is usually activated during reduced operation. Is a mechanism included? ? Facilities to maintain the minimum flow/pressure at the nozzle. It generally works during load-reduction operations.

I provide an English explanation of a device that is somewhat comparable, for Echo’s reference: BLOCK 5 – EMERGENCY STOP Provisions. An Emergency Stop is a safety device designed to stop the movement of the machine’s axes in the event of a dangerous situation arising. It is typically a device that interrupts the power supply to the motor drivers in order to halt movement once activated. The Emergency Stop button must always be within the reach of the machine operator while he or she is inside the machine’s danger zone. Further details on the Emergency Stop functionality of this package will be provided on a subsequent page.
In the information you provided, the Emergency Stop button is referred to as the \"emergency stop button\", and it is usually installed on the control panel in the main control room. It’s a bit different from what I wrote.
\"Provision\" here should refer to measures and regulations. Software cannot be translated literally; it refers to a program for setting controls, while stop means to shut down the equipment urgently (such as closing valves). In general, it means including provisions for the minimum flow rate in emergency situations, in order to ensure a minimum flow rate/pressure at the pipe outlet.
“provision” is the noun form of “provide”, meaning to supply. There are usually two forms of minimum stops: software minimum stop and mechanical minimum stop. They are all used for the control of valves. In the active state, it ensures the minimum set value. For example, the mechanical minimum stop of a valve is a mechanical baffle installed at the bottom of the valve’s bore. In this way, when the valve is opened and closed, its maximum travel is limited to the position of the mechanical baffle, which ensures minimum flow control for the valve. Similarly, software min. stop is the minimum flow control value set in the control software. Personally, I think it can be translated as “software minimum data volume setting”. provision can be left untranslated.
A software minimum flow stop provision is included to maintain a minimum flow/pressure to the nozzles. I think it should be translated as: A set of software-based measures for stopping operation at the minimum flow level is included to ensure a minimum flow/pressure at the nozzles.
A software-based minimum flow stop mechanism is included to ensure a minimum flow/pressure is maintained at the nozzles. This mechanism is typically activated during reduced operation. The software implements a minimum flow limit to maintain a certain minimum flow/pressure at the nozzles. It is usually applied during load reduction. I agree with Pattaya’s view; what is meant here is to set a minimum valve position output in the DCS system for the control valves, in order to prevent the valves from closing completely when the load is reduced.
provision is translated as “facility”; it may include certain logic and components. It includes a set of software-based minimum flow facilities to maintain the minimum flow/pressure to the nozzle. It generally works during load-reduction operations. :handshake :handshake :handshake
I think this should be the low limit of DCS; by \"software\", it actually refers to what is implemented on DCS. Corresponding to this is the mechanical minimum stop. Mechanical low limit. “Provisions” is the noun form of “provide”; it serves to set a lower limit for the valve, and it does not refer to facilities in this context. This is my personal opinion for reference only.
