一、Outline： Oil mixing with water signal is used to monitor hydropower, thermal power plants and large-scale systems pumping oil mixing with water or water quantity. When the fuel tank, mixing with water or water in oil pipeline that is a warning signal to alert staff on duty promptl...
一、 the purpose and principleThe signal level meter for water, fire power plants and other industrial sectors of water, oil, medium level of monitoring, control, limit alarm, etc.The signal Simple structure, mainly magnetic and magnetic water float float oil packed in plexiglass tube, (WXJ type float insert liquid tank), the float level with the lift and upper and lower action, you can directly observe the test high and low level. In the ...
一、 use：One signaling device signaling device shaft peristaltic hydropower units are designed for condition monitoring. When the unit is shut down, when as a result of poor sealing vanes or other reasons, leaking is excessive, often leads to unit shaft motility, which each part of the unit pad thrust bearing bush in particular caused a very negative impact, damage to the unit performance and service life, therefore, at the unit shutdown, moni...
