在粘胶生产过程中,碱液是其主要的原料之一。我公司对碱计量采用的是浮筒式遥测液位计。该仪表采用浮筒和重锤的指针指示,在使用过程中经常存在以下问题①鼓形轮经常被钢绳所帯带的碱液密死,导致仪表指示不准②重锤重量不足,至使重锤下滑迟最,甚至不下滑,无法带动指针,导致仪表指示
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
数字液位检测仪主要由四部分成:J检测电路,步电机脉冲分配电路,步电机驱动电路②计数、置控制高度、数部分电路」①控信号弘动、输出报警电路」④①齿轮变速构。图一为数字液位检仪结构棋图。
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
