The series of high-pressure magnetic float level gauges for steam drums are widely used as instruments for monitoring liquid level in petrochemical, metallurgy, thermal power plants and other industrial sectors. Especially in the use of various boiler drums of 50MW, 125MW, 200MW, 300MW and 600MW in thermal power plants, it is very popular among users. The special high-pressure magnetic float level gauge for steam drum has the characteristics of simple structure, clear display, less maintenance, low cost, safety and reliability.
The high-pressure magnetic levitation level gauge for steam drum is composed of three parts: the watch body, the float and the display. The watch body is made of stainless steel, and the float is made of high-strength titanium alloy material. They have the characteristics of high temperature resistance, high pressure, corrosion resistance, etc. Steel, which uses high temperature resistant rare earth samarium cobalt permanent magnet material, the Curie temperature of complete demagnetization is 800 ℃, and it will never demagnetize in the environment of 380 ℃ ~ 550 ℃.
The ceramic rotor of the display is composed of two colors, red and green (red and white). The rotor of the display is driven by the magnetic force of the float in the display to rotate half a circle. When the liquid level rises, it turns green (white), and when the liquid level falls, it turns red, and its red and green (white) The boundary is the liquid level. Can also be equipped with red and green LED electronic display. There are gauges on both sides of the display to indicate the liquid level value. In order to ensure that the float in the watch body can float up and down flexibly and prevent iron filings from entering, a magnetic filter device can also be installed on the connecting pipe of the product according to user needs.
