磁翻板液位计容易出现哪些问题?

磁翻板液位计常见问题与故障及注意事项磁翻板液位计常见问题与故障及注意事项为您解决一般常见的液位的问题与故障。现场调校中偶尔会发现浮子上下移动不够灵活。这大多是由于安装不当引起的,磁翻板液位计此时要注意上下法兰的中心是否在一条线上,是否与水平面垂直。一般来说,与水平面夹角最好不小于87度,如果偏差较大,可能会影响浮子的顺利移动。    液位计调校正常,投用后发现浮子在某一位置出现一段时间的“吸住”现象。这主要是液位计穿过钢制平台安装时,与钢板距离过近产生的。因此,穿过钢制平台安装需要特别注意液位计连通管管壁与平台切割边线的间距。烟台铭科、根据现场使用经验,此间距在100㎜左右即能保证对磁性浮子不产生影响。    液位计现场投用时,要特别注意应先打开上部闸阀,后打开下部闸阀。玻璃管液位计这是由于液位计连通管的底部装有保护浮子的止推弹簧,否则,大差压的作用可能撞碎浮子导致液位计无法使用。    液位计投用一段时间后,出现浮子难以浮起且浮子移动不灵活的情况。这基本上是因为磁性浮子上沾有铁屑或其他污物造成的。可先排空介质,再取出浮子,消除磁性浮子上沾有的铁屑或其他污物即可。    如果因运输或其他原因导致现场指示用的密闭玻璃管破裂,则可用国产玻璃管更换。但最好能抽真空。烟台铭科、重锤式料位计还要注意玻璃管是否垂直,以免影响指示器的指示。    液位计使用过程中,如果输出信号产生频繁扰动或有干扰脉冲,就要检查信号电缆屏蔽层是否可靠接地,工作接是电阻能否满足要求。倘若干扰仍然没有完全消除,可用信号隔离器来解决。    液位计使用时尤其要注意,千万不要用强磁铁在连通管外上下拉动浮子进行检查.否则会导致磁性浮子磁化而改变极性,甚至会使浮子磁性减弱,以致难以正常工作。    选用本安型液位计时,尤其要注意液位计与安全栅的阻抗是否匹配。由于此液位计电源电压为14.5-36VDC,小于一般变送器的14.5-45VDC,故负载较大时不能正常工作
Magnetic level indicator is common problems and faults and matters needing attention of magnetic level gauge common problems and faults and the matters needing attention to solve the problem and fault common level for you. Field adjustment will occasionally find the floater moves up and down is not flexible. This is mostly due to improper installation, magnetic level gauge at this time to pay attention to whether the center of the upper flange and the lower flange in a line perpendicular to the horizontal plane, whether. In general, and the horizontal plane angle should not less than 87 degrees, if the deviation is big, may affect the smooth movement of the floater. Liquid level gauge adjustment is normal, after the commissioning of the float in a position that a period of "suck" phenomenon. This is mainly liquid level gauge through the steel platform installation, and the steel plate are too close to the. Therefore, through the spacing of steel platform installation should pay special attention to level meter pipe wall and platform of cutting edge. Yantai Mingke, according to the practical experiences, this distance in 100 mm or so to ensure that it does not affect the magnetic float. Using field level meter, special attention must be paid to open the upper valve, lower valve open. Glass tube level gauge which is due to the communicating pipe liquid level gauge is installed at the bottom of the protection float thrust spring, otherwise, the big differential effect may float level gauge cannot be used to crash. Liquid level gauge for use after a period of time, appear to float to float and float can not move flexibly situation. This is basically because the magnetic float stained with iron or other contamination caused by. Can first emptying medium, and then remove the float, eliminate magnetic float with some iron or other filth. If for transportation or other reasons for airtight glass field for indication tube rupture, usable domestic glass tube replacement. But the best vacuum. Yantai Mingke, hammer type material level meter also note glass tube is vertical, so as not to affect the indication. Liquid level meter in use process, if the output signal to generate frequent disturbance or interference pulse, it is necessary to check signal cable shielding layer is reliable grounding, grounding resistance can meet the requirements of the work. If the interference is still not completely eliminated, can be used to solve signal isolator. Pay particular attention to the liquid level gauge is used, do not use strong magnets in the connecting pipe to inspect pulling floater outside. Otherwise it will result in changing the polarity of magnetization and magnetic float, and even make the float magnetic weakened, so that it cannot work normally. The intrinsically safe level timing, with particular attention to the impedance level meter and safety grid matches. Because this level of the supply voltage is 14.536VDC, less than the general transmitter 14.545VDC, the load is large can not work normally
