在粘膠生產(chǎn)過(guò)程中,堿液是其主要的原料之一。我公司對堿計量采用的是浮筒式遙測液位計。該儀表采用浮筒和重錘的指針指示,在使用過(guò)程中經(jīng)常存在以下問(wèn)題①鼓形輪經(jīng)常被鋼繩所帯帶的堿液密死,導致儀表指示不準②重錘重量不足,至使重錘下滑遲最,甚至不下滑,無(wú)法帶動(dòng)指針,導致儀表指示
Alkali liquor is one of the main raw materials in viscose production. Our company adopts float type telemetry liquid level meter for alkali measurement. The indicator of buoy and heavy hammer is used to indicate the instrument. There are often the following problems in the use process: ① drum wheel is often blocked by the alkali liquid carried by the steel rope, resulting in inaccurate instrument indication; ② the weight of the heavy hammer is insufficient, so that the weight of the heavy hammer is delayed or even does not slide, and the pointer cannot be driven, which leads to the instrument indication
數字液位檢測儀主要由四部分成:J檢測電路,步電機脈沖分配電路,步電機驅動(dòng)電路②計數、置控制高度、數部分電路」①控信號弘動(dòng)、輸出報警電路」④①齒輪變速構。圖一為數字液位檢儀結構棋圖。
The digital liquid level detector is mainly composed of four parts: J detection circuit, stepper motor pulse distribution circuit, stepper motor drive circuit; ② counting, setting control height, and several parts circuit ＂ ① control signal amplifying and output alarm circuit ＂ ④ ① gear speed change mechanism. Figure 1 is the structure diagram of the digital liquid level detector.

1。 In the detection circuit, there are three states of the relative position between the two ends of the detection head T1 and T2 and the liquid level. ① The detection head T1 and T2 are not immersed in the liquid level; ② the detection heads T1 and T2 are immersed in the liquid level; ③ T1 is immersed in the liquid level, and T2 is on the liquid level. When contacting the liquid level, the detection head is at high level "0 ° and becomes low level" 1 "after leaving the liquid level. Seven gates are used in the detection circuit
