法兰式液位变送器应用深度污泥压滤脱水系统预处理/板框式压滤机工作原理为通过板框的挤压，使污泥内的水通过滤布排出，达到脱水的目的。它主要由凹入式滤板、框架、自动-气动闭合系统、侧板悬挂系统、滤板震动系统、空气压缩装置、滤布高压冲洗装置构成，体积庞大。板框式污泥压滤机为了达到压滤脱水的效果需要添加铁盐与石灰作为添加剂，这无疑增加了污泥压滤成本，并且给污泥进行了增量，然后再进行污泥脱水工作。且在污泥脱水、压滤后，处理滤布上的污中需要人工操作，工人的劳动强度大，工作效率低。

The flange type liquid level transmitter applies the pre-treatment / plate and frame type filter press of the deep sludge pressure filtration dehydration system, whose working principle is to squeeze through the plate and frame, so that the water in the sludge is discharged through the filter cloth, so as to achieve the purpose of dehydration. It is mainly composed of concave filter plate, frame, automatic pneumatic closing system, side plate suspension system, filter plate vibration system, air compression device and filter cloth high-pressure washing device, with huge volume. In order to achieve the effect of pressure filtration and dehydration, plate and frame type sludge filter press needs to add iron salt and lime as additives, which undoubtedly increases the cost of sludge pressure filtration, and increases the sludge, and then carry out sludge dehydration. After sludge dewatering and pressure filtration, manual operation is needed to deal with the waste on the filter cloth. The labor intensity of workers is high and the work efficiency is low.

法兰式液位变送器应用深度污泥压滤脱水系统预处理/ 在实际使用中,一般仪表技术人员都能注意小心使用,很少出现上述故障。而变送器的工作特性变成非线性的原因,大多数是由于毛细管中的灌充液泄漏所致。一般情况下,灌充液的密封是非常好的,正确使用台此类变送器,在3~6年内,泄漏量很小,线性还可以。如果使用时间更长的话,由于微小泄漏的长期积累,就会使灌充液过少,有时可以明显看到感应膜片凹陷,从而使变送器失去线性度而不可用。另一种情况是由于仪表技术人员未能注意工作温度所致。下面我们先看一看常用的几种灌充液的特性

The flange type liquid level transmitter is pretreated by the deep sludge pressure filtration dehydration system / in actual use, the general instrument technicians can pay attention to the careful use, and rarely the above failures occur. Most of the reasons for the non-linear working characteristics of the transmitter are due to the leakage of filling liquid in the capillary. In general, the sealing of filling liquid is very good. If the transmitter is used correctly, the leakage is very small and the linearity is OK within 3-6 years. If the service time is longer, due to the long-term accumulation of small leakage, the filling liquid will be too little, sometimes the sensing diaphragm depression can be seen obviously, so that the transmitter loses linearity and is not available. The other is due to the instrument technician's failure to pay attention to the working temperature. Let's take a look at the characteristics of several commonly used filling fluids
