The Composition of the Mica Sheet in the Water Level Gauge
The mica sheet in the water level gauge is composed of multiple siliceous mica, quartz, garnet, and ruby, and may also contain sodium feldspar, amphibole, and actinolite. The garnet is rich in Fe and Mg, and the Si in the siliceous mica can reach 3.369, which is a high-pressure combination. It has insulation and low-loss thermal resistance functionality and is also a good blackbody.
The mica sheet in the water level gauge is a direct-reading instrument designed and manufactured for detecting water (liquid) level in steam boilers or other pressure vessels in thermal power plants, petrochemical industries, and other industrial and mining enterprises. It is a low-deviation mica water level gauge developed based on the advantages of various water level gauges at home and abroad, displaying “steaming red and water green” where it shows the level. It is all red when there is no water, full green when there is full water, and the red-green interface corresponds to the actual water level, which can be directly observed on-site. With a color industrial TV monitoring system, the actual water level on-site can be remotely monitored on the monitor screen in the control room.
It has good flushing effect, and the window is not easily fouled. The water level on the left and right side of the water level gauge is slightly different. Due to the large contact area with condensate for this series of products, and the addition of a condensate tank at the top, a part of the steam turns into condensate water and can flush the observation window surface along the window, making the window not easily fouled. The wall thickness of the condensate tank is smaller on the side away from the connecting pipe, and the condensation speed is faster, so that a large amount of saturated water can be replenished into the water level gauge, making the water level difference between the left and right side of the gauge very small.
What Is the Mica Sheet in the Water Level Gauge?
The mica sheet in the water level gauge is a type of connecting pipe principle water level gauge, which is designed based on the traditional two-color water level gauge and equipped with a set of heat-generating circulation system to improve the measurement accuracy.
This series of water level gauges mainly consists of an optical source box, a water level gauge body, a balance pipe, a sewage pipe, a water connecting pipe, a steam-side sampling pipe, a water-side sampling valve, a steam-side sampling valve, a saturated steam heat accompanying pipe, a drainpipe, a condensate tank, and other components.
The product uses the saturated steam in the steam pocket to enter the saturated steam heat associated tube through the steam-side sampling pipe, heats the water level gauge body, reduces the heat transfer of water in the water connecting pipe, and uses the saturated water condensed in the condensate tank to replace the water in the water connecting pipe, accelerating the water circulation, making the water in the water connecting pipe closer to the temperature of saturated water, thereby eliminating the deviation caused by the water column density in the measurement pipe of the water level gauge, ensuring that the water level in the water connecting pipe is close to the actual water level in the steam pocket under any conditions, achieving the goal of accurately monitoring the water level in the steam pocket.
