氣力輸送倉泵的就地控制柜是用于控制倉泵現(xiàn)場運(yùn)行的設(shè)備，通常每臺倉泵設(shè)置一臺，也可多臺倉泵設(shè)置一套，置于倉泵體上。以下是其相關(guān)介紹：

　　The local control cabinet of the pneumatic conveying bin pump is a device used to control the on-site operation of the bin pump. Usually, one bin pump is set up for each bin pump, or multiple bin pumps can be set up in one set and placed on the bin pump body. Here is the relevant introduction:

　　功能

　　手動操作：柜內(nèi)設(shè)有電器控制按鈕、電磁閥與模擬面板，通過“手動/自動”旋鈕切換至手動模式，可對倉泵上的所有氣動閥門進(jìn)行單獨(dú)操作，如打開或關(guān)閉進(jìn)料閥、出料閥等，主要用于倉泵的調(diào)試和故障維修時的現(xiàn)場操作。

　　Manual operation: The cabinet is equipped with electrical control buttons, solenoid valves, and analog panels. By switching to manual mode through the "manual/automatic" knob, all pneumatic valves on the bin pump can be operated separately, such as opening or closing the feed valve, discharge valve, etc. It is mainly used for on-site operation during the debugging and fault maintenance of the bin pump.

　　自動運(yùn)行：當(dāng)旋鈕打到自動位時，就地控制柜在控制系統(tǒng)的控制下，按照預(yù)設(shè)程序自動控制倉泵的進(jìn)料、流化加壓、輸送等工作流程，實(shí)現(xiàn)物料的連續(xù)輸送。同時，模擬面板可實(shí)時模擬顯示該泵的當(dāng)前工作狀態(tài)。

　　Automatic operation: When the knob is turned to the automatic position, the local control cabinet, under the control of the control system, automatically controls the feeding, fluidization pressurization, and conveying processes of the bin pump according to the preset program, achieving continuous material conveying. At the same time, the simulation panel can simulate and display the current working status of the pump in real time.

　　組成

　　compose

　　電源部分：通常接受就地配電箱提供的AC220V電源，為控制柜內(nèi)的電器元件、PLC分站等提供電力。

　　Power supply: It usually receives AC220V power from the local distribution box to provide power for electrical components, PLC substations, etc. inside the control cabinet.

　　PLC分站及模塊：部分就地控制柜內(nèi)設(shè)PLC分站，并選配AI/DI/DO模塊，用于采集現(xiàn)場信號（如壓力、料位等）和控制閥門等執(zhí)行元件的動作。

　　PLC substation and modules: Some local control cabinets are equipped with PLC substations and AI/DI/DO modules, which are used to collect on-site signals (such as pressure, material level, etc.) and control the actions of executing components such as valves.

　　電磁閥組：用于控制倉泵的氣動閥門，通過電磁線圈的通斷來切換氣路，從而實(shí)現(xiàn)閥門的開閉。

　　Electromagnetic valve group: used to control the pneumatic valve of the bin pump, switching the air path through the on/off of the electromagnetic coil to achieve the opening and closing of the valve.

　　技術(shù)參數(shù)

　　Technical Specifications

　　電源電壓：一般為AC220V。

　　Power supply voltage: generally AC220V.

　　防護(hù)等級：根據(jù)現(xiàn)場工況而定，部分采用雙層門密封，防護(hù)等級可達(dá)到IP54以上，以適應(yīng)粉塵、潮濕等惡劣環(huán)境。

　　Protection level: Depending on the site conditions, some parts are sealed with double-layer doors, and the protection level can reach IP54 or above to adapt to harsh environments such as dust and humidity.
