Drum double colour water level gauge

Products overview:

ZW - B69X seriesIs no instrument can take the place of in situ observation instrument at home and abroad.Red, it is using the optical principle with "steam aqua green" to display the steam in the boiler, the water level change.Two rows of compensation type window, dislocation type window to observe the continuous interval, and the light is downy, clear interface.On the table body has three waterproof line makes the sealing effect is better.Special bolt eradicated bite after quenched and tempered wire, broken wire phenomena.The table structure is simple, direct display, wide measuring range, high measuring accuracy, whether on-site or master control room monitoring effect.Is applied to high pressure, ultra-high pressure, subcritical power boiler ideal water level gauge.

Second, the working principle:

ZW series - B69X drum double-color gauge through steam, water valves and steam drum side and water side connected to form the tower, the use of the principle of communicating vessels so that water level gauge water level consistent with steam drum water level.Is, of course, after the normal operation of boiler, because inside the boiler steam drum and field of temperature in the water level gauge is different, can cause the proportion of interior and exterior saturated steam boiler steam drum water is different, so the water level gauge shows that steam drum water level with the actual boiler water level there is a certain difference.

Three, according to principle:

ZW series - B69X drum two-color level meter toward the table separately by the light source the light body of observation window, in the vapor phase section of the table body, red light headed, right in front of the green oblique to the wall is absorbed;At the same time in the liquid phase, in part due to the refraction of water makes the green light at front, red light slanted to the wall is absorbed.So in front observation steam will get red, aqua green;Steam water flooded all red, all over the green display effect.

Four, applications:

ZW - B69X series high temperature and high pressure steam drum double color water level gauge is mainly used for power plant boiler water level gauge observation hole, transparent, wave, high temperature resistance, corrosion resistance, scouring resistance, insulation, smooth and clear, high frequency low dielectric loss properties.Can be used in high frequency medium, high temperature vacuum and high temperature and high pressure, strong acid, strong alkali, working environment, under the rapid changes in temperature and pressure also does not affect its chemical properties and optical transparency, and therefore is a coal-fired power plant, oil refineries, chemical plants, etc. High pressure steam boiler water level gauge of ideal material for protecting lining.

Five, the main features:

1, table body bolt hole, the water level gauge slitting line, table body plane and plate surface using fine grinding, don't let it out.

2, table body by two rows of compensation type window, dislocation type window, eliminated the original mica double-color gauge shortcomings of blind area;Bolt and rotary table body, prevent the bite silk, silk, change the deficiency of the past.

3, the two rows of Windows on the table, through optics refraction principle, right in front of gauge can observe the arrival time when you watch the water level up your bag and the water level value accurately.

4, light meat change, red, green, clear, clear boundaries.

5, water level gauge adopts long window structure, wide observation inspection, high transparency.

On 6, table body has three waterproof lines, and USES the special sealing material, not leak, prolong the service life of the product, reduce working intensity of maintenance personnel, reduce the maintenance cost.

7, cold light source adopts the new light source, long service life.

8, when the water level TV monitoring system is used, the drum water level and water level monitor synchronization, the picture is clear.

Six, the technical parameters:

1, nominal pressure: 16 mp, 25 mp, 32 mp;

2, the interface form: welding, flange connection;

3, temperature, saturated;

4, center distance: 535 mm - 1270 mm;

5, visual length: 380 mm - 800 mm;

6, light source: led, halogen tungsten lamp, flat tubes;

7, power transformer: 40 v input 35 v, 220 v output, 45 v power 600 w, 1200 w.

Seven, product specifications:

1, no blind area (compensation) : five, five paragraphs long, 7, 9, 11;

2, no blind area (dislocation) : two, four, six paragraphs, eight, ten;

3, have blind area: three or four paragraphs;

Part 4, light source: led, halogen tungsten lamp, flat light could be selected according to user requirements.

Eight, double color gauge mica components technical requirements:

1, the thickness of mica components with 16 mpa pressure is greater than 1.5 mm, with 2 mm thickness pressure is greater than 25 mpa, match 32 mpa pressure is greater than 2.5 mm thickness, formulate specific thickness according to user requirements and component plant size and pressure to determine the mechanical and electrical group.

2, water level gauge with mica sheet length error must not exceed 0.5 mm, the width of the error must not exceed 0.3 mm, bull 's-eye type circular gauge mica sheet error must not exceed 0.2 mm, the thickness of the single chip requirements within 0.1 0.25 mm.

3, mica sheet of high quality, transparent, smooth and clarity is good, the surface must not have impurities, scratches, spots, sａnd holes, layering and corrugated exist.

4, double-color water level gauge glass mica components with high temperature and high pressure aluminum silicon glass, glass size appropriate, no crack, scratch, good transparency.

5, other graphite gaskets, monel alloy cushion, cushion gasket, protection zones are also pressing, the thickness of the standard, smooth, no cracks.

* our factory equipped with various types of water level gauge mica spot sealing components, after receiving the order, with the express mail delivery immediately, users receive product just 3 days, ensure the quality of products in the premise, each group of water level gauge mica component price is 10% lower than the other manufacturers - 20%.Reliable quality, reasonable price, timely delivery.

Nine, maintenance and matters needing attention:

1, the water level gauge of components by artificial mica sheet, natural mica sheet and the graphite pad.

2, synthetic mica sheet contact medium, graphite pad when installation, must according to the size of the surface installation.

3, red and green glass in the same bracket, green glass on the right side of the table body, such as steam upside will be green and pink, the water level of misleading.

4, install the mica sheet correctly placed, the screw fastening clamp again, then diagonally fastening, strength gradually to 90 n. m, 120 n. m, n. 150 m and 180 n. m four times and tighten closely, ensure the smooth.

5, water level gauge for a long time to run the mica sheet may also scaling, at this time must be to wash.Washing method: close the valve, open the water valve, make the table body internal water rose to the top, 4-5 times, open the drain valve rinsed repeatedly.Mica components such as flushing impurities should be replaced.
