SP 2000UV/UVPC Visible Spectrophotometer

SP 2000UV/UVPC Visible Spectrophotometer

SP 2000UV/UVPC Visible Spectrophotometer

Can you believe? An UV-Vis spectrophotometer costs less than ten thousand, but with power on self-testing, automatic wavelength calibration, light source auto- switching, PC controlled, etc. In the past, it might cost several ten-thousand even decuple with these advanced functions.

SP-2000UV UV-Vis spectrophotometer takes use of high precision sine mechanism as a wavelength driver. Program control, wavelength accuracy, and the linearity over the full wavelength are obviously better than those of the congener instruments in which gear and rack is used as a wavelength driver, and a gauge dial is used for wavelength display.

Spectral scanning

In the instrument s wavelength range, run spectra scanning for sample according to the setting wavelength range, get the curve of Absorption/Transmittance vs. wavelength to analyze the spectrum characteristic and identify the maximum absorbance peak. User can do spectrum smoothing, peak or valley detecting, and overlap several spectrum curves to do four basic calculations, print and save the data. http://www.hinotek.com/

Potterton Puma 80e Combination Boiler Fault

Potterton Puma 80e Combination Boiler Fault

Potterton Puma 80e Combination Boiler Fault

It was clear when we arrived that the 3 bar pressure relief safety valve had been letting water pass out of the system and out of the building through the pressure relief pipe. This could be simply a fault with the pressure relief valve but much more commonly it s caused by the failure of the expansion vessel in the boiler or the loss of charge pressure from the expansion vessel

Changing the internal expansion vessel wasn t going to be easy as there was insufficient clearance above the boiler; we d have had to take the boiler off the wall. We decided to fit an external 18 litre expansion vessel, connected to the central heating return pipe close to Once a 3 bar pressure relief valve has been operated, the valve will often refuse to re-seat properly and will drip water out through the pressure relief pipe, again losing pressure. We don t use the safety valve to drop the system pressure unless the valve has already been letting by. Dropping the pressure by draining water from a drain cock may be more effort but it saves changing the safety valve. The Puma boiler has a small bleed valve which can be used to drop the pressure. It s fitted on the flow pipe just below the diverter valve assembly.

The pressure relief safety valve valve on this boiler was slowly letting by so we changed it too and then raised the system pressure to just over 1 bar. The boiler then operated normally, with a rise in pressure from cold to hot of only about 0.3 bar. That rise in pressure will vary depending the size of the heating system and the size of the expansion vessel. It also depends on the rise in temperature of the system from cold to hot but typically it s up to ? a bar.

Finally, where we ve not been able to replace an expansion vessel straight away and the customer needed the heat, we have allowed air into one of the radiators (half full of air was usually OK). The air in the radiator then temporarily took up the expansion, allowing the boiler to run. http://www.luofuvalve.com/

Mine pump patented structure characteristics

Mine pump patented structure characteristics

Mine pump patented structure characteristics

The water supply is back to normal after water break, the water level rises and flushes pump base, mine pump can automatically drain. When drain line brake valve opening locked tonnage is larger than water inflow of mine, mine pump can automatically adjust flow rate and will not interrupt draining, and does not stop and open pump. Therefore, it has become new model of automatic draining.

Sprinkler is the watershoot extracted from air dome of top bump body.

Sprinkler is the channel of draining leaky water of axle hole of pump body promptly outside pump body (see picture one). Sprinkler has two or more, they can make the pressure in air chamber cavity always keep the same with atmospheric pressure outside cavity. Therefore, do not block the sprinkler.

Some people do not read operation instruction and mistake Sprinkler to be main watershoot, cause the accident, and make a joke. It should be a warning.

Oil storage chamber is also at the bottom of vertical motor.

Its greasy surface is higher than upper end ring of mechanical seal. It can make the lubrication of mechanical seal, cooling conditions better. If lubricating oil or water leaks from mechanical seal to motor, Sprinkler can accept and drain with dew.

In the same side of junction box, on the outerwall of motor, first install Oil storage chamber relief safety valve B (see picture one), When high pressure of main cavity transfers into Oil storage chamber or oil temperature rises unusually, automatic and timely relief safety. First increase pouring tube beside Safety valve B and inspect oil level or supplement motor oil.

Safety valve: safety valve A and safety valve B are the automatic relief safety protecting device set up first to eliminate hidden dangers of motor explosion.

In the past, mechanical seal of old submersible pump easily goes into the water, after motor overload or fault, winding overheating makes main cavity produce high temperature, make water going into the main cavity of high-pressure steam, often cause motor explosion accidents (cause panic in some mines). To prevent closed motor explosion, the new mine Pump installs sprinkler relief safety valve A on the outerwall of motor.when doing Explosion resistance experiment, main cavity of motor injects flammable gas, after lighting and exploding , Most gas flame cools after going through Flameproof surface of bearing cover (the first group), through bearings, enter sprinkler from via hole (A); small gas flames through the Flameproof surface of flameproof round pipe fittings and flameproof cylinder set up in the round hole (b) , enter sprinkler After cooling , And then drain automatically and safely from sprinkler relief safety valve A outside Motor. In common use, if overheat, the high-pressure gas produced by winding will carry out automatic and timely relief safety pressure along the path above, thus stop the motor explosion accidents caused by the accumulation of pressure and the superimposition of pressure. http://www.luofuvalve.com/

Green and Sustainable Woven Metal Mesh Reduces Energy Consumption

Green and Sustainable Woven Metal Mesh Reduces Energy Consumption

Green and Sustainable Woven Metal Mesh Reduces Energy Consumption

The inherent aesthetics and unique functionality of woven metal mesh make it a practical choice for almost any building application. Within the healthcare and educational building sectors, the unique material has become increasingly popular because of the added sustainable benefits it provides – a key consideration in conjunction with green building standards.

Depending on how it is incorporated into interior or exterior building design, woven metal mesh lends to an application’s green and sustainable attributes with benefits such as increased ventilation, reduced solar heat gain, light pollution reduction and recyclability to name a few. Metal mesh can additionally contribute to United States Green Building Council (USGBC) Leadership in Environmental and Energy Design (LEED) Certification. Specifically, woven metal applications can garner LEED credits within the New Construction (NC) category, and can also provide green benefits for renovation purposes.

These sustainable attributes – coupled with the stunning visual appeal and functional advantages that only woven metal can provide – make it an excellent choice for various solar and ventilation related applications within the healthcare and educational building segments.

Solar Canopies

For buildings with adjacent exterior courtyards, school playgrounds or any other outdoor area that requires shading, woven metal mesh can also be used for solar canopy purposes.

As an exterior solar shading system, a canopy fabricated from woven metal mesh maintains the unique ability to allow air to flow through it. Solar canopies fabricated from architectural mesh also lend an element of dynamic visual interest to an outdoor space while still providing the specified level of shading. http://www.xyl-wiremesh.com/
