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.

Throttle Body Spacers - All The Types You Want

Throttle Body Spacers - All The Types You Want



Whenever taking care of your car you should confirm that your car has a properly fitted body spacer. The throttle body spacer enables you to do a lot with your money because it helps you save the money that you would have otherwise spent on buying more fuel. More often the main reason why your fuel tank seems to empty very fast even after filling it, is because of fuel wastage- the fuel does not burn completely. If you want to know that your throttle body spacer is not working properly fitted, your car will produce a lot of smoke.



The throttle body spacer enables the large volumes of air incoming into the engine to be mixed with fuel properly so that there will be sufficient combustion of fuel. Fuel combustion will not be very effective in case there is a limited supply of oxygen. To ensure that this does not happen, then there should be plenty of air flowing into the engine. This is what the body spacers like the Acura throttle body facilitate. There are different types of throttle body spacers depending of the variety of engines. You can purchase a Mustang 5.0 throttle body spacer or you like to have more power with a less throttle then a 4.3 throttle body spacer will work for you very well.



To purchase a body spacer is very easy nowadays because of the increase in supply. They have become quite cheaper and readily available. The onset of Internet marketing has simplified the problem of find one for you. If you visit some website like www.throttlebodyspacers.com then you will be able to find the best throttle body spacer that works for you. They are categorized according to the models of the cars for example you will find a throttle body spacer for Toyota, KIA and the likes. Models like Nissan since they have different types of engines then you can purchase one that suits your need. If you want a 240sx throttle body, then such a website will be of great help. Considering how unavailable the 240sx spacers you can find them in abundance on the website stated above. Here you are assured of high quality stuff.

Cleaning the GM Electronic Throttle Body

Cleaning the GM electronic throttle body



You don t need to remove the Throttle Body to clean it. Now, having said that, the BEST and most thorough cleaning is done with the Throttle Body removed. But again... you don t have to.



The following instructions assume that you re cleaning the Electronic Throttle Body with it installed on the Engine.



OK, this is what you ll need to do:



Remove the MAF Sensor and Air Intake Hose Assembly as one unit.

The Throttle Bore and Throttle Plate are now exposed.

Important : The Key must be in the OFF position or completely removed.

If the Key is in the ON position, the Throttle Plate could suddenly move and cause physical injury to a finger or hands (when doing the actual cleaning).

Spray solvent on the Throttle Plate and Throttle Bore.

If the deposit build up is not that bad, you can use a shop towel soaked in the appropriate solvent to clean the Throttle Body bore and Plate.

If deposits are too stubborn, you can use a toothbrush to scrub the deposits on the Bore and Plate.

Once you re done, install the MAF Sensor and Air Duct Assembly and reconnect all electrical connectors.

Start the Engine and let it idle for about 5 minutes.

Your pickup or SUV will blow some smoke out the tail-pipe for about 30 seconds.... then clear up.  http://www.boweijc.com/

Relief valve

Relief valve



In the petroleum refining, petrochemical and chemical manufacturing, natural gas processing and power generation industries, the term relief valve is associated with the terms pressure relief valve (PRV), pressure safety valve (PSV) and safety valve.



In practice, people often do not stick to the technical distinctions between the most common abbreviations: SRV, PRV, SV and RV



pressure relief valve (PRV) or pressure safety valve (PSV). The difference being that PSVs have a manual lever to activate the valve in case of emergency. Most PRV are spring operated. At lower pressures some use a diaphragm in place of a spring. The oldest PRV designs use a weight to seal the valve.



Set pressure: When increasing system pressure reaches this value the PRV opens. Accuracy of set pressure often follows guidelines set by the ASME.



Relief valve (RV): A valve used on a liquid service, which opens proportionally as the increasing pressure overcomes the spring pressure.



Safety valve (SV): Used in gas service. Most SV are full lift or snap acting, they pop open all the way.



Safety relief valve (SRV): A PRV that can be used for gas or liquid service. But set pressure will usually only be accurate for one type of fluid at a time (the type it was set with).



Pilot-operated relief valve (POSRV, PORV, POPRV): device that relieves by remote command from a pilot valve that is connected to the upstream system pressure. Low-pressure safety valve (LPSV): automatic system that relieves by static pressure on a gas. The pressure is small and near the atmospheric pressure.



Vacuum pressure safety valve (VPSV): automatic system that relieves by static pressure on a gas. The pressure is small, negative and near the atmospheric pressure.



Low and vacuum pressure safety valve (LVPSV): automatic system that relieves by static pressure on a gas. The pressure is small, negative or positive and near the atmospheric pressure.



Snap acting: The opposite of modulating, refers to a valve that "pops" open, it goes into full lift in milliseconds. Usually accomplished with a skirt on the disc so that the fluid passing the seat suddenly affects a larger area and creates more lifting force.



Modulating: Opens in proportion to the overpressure formed.  http://www.luofuvalve.com/

Forged Steel Pipe Fittings

Forged Steel Pipe Fittings



Use a sharpening steel to realign the edge and to keep it sharp. The services location of the coal hopper is important since the coal has to be stored near enough the fire to allow for easy transfer of the coal from the hopper to the fire as and when more fuel is required. High Pressure die casting is one such method that employs a filler tube to pour the molten magnesium, which is referred to as a shot sleeve. We like the world condensed into bite- sized chunks Forged steel pipe fittings for our amusement; that way, as soon as we get bored, we can simply move on to Forged steel pipe fittings the next one, and the next one, leaving a trail of discarded phones, cars and kitchen appliances on our wake. Mr. It is applicable to manufacture the cutting tools for processing high temperature alloys, stainless steel, titanium alloys, high- strength steel, and other hard materials.

The downside of this process is its cost, therefore it is only implemented if significant cost reduction can be achieved. Stainless Steel Products tick all the recycling boxes. Always try and keep the pipe from the blower to the forge straight as bends will reduce the airflow. The sale of gas valves, and found such a primitive form of deception, as replacement faucet handles on manufacturing native yellow – gas ( gas valves are more expensive). Forging steel is one of the earliest heat treatment methods of steel discovered by man. Again, it depends on the scenario. These standards include the copper content 57- 60%, zinc – up die to 40%, lead within 0, 8- 2, 2%. His intention was to cultivate coffee on the lush volcanic island of Martinique. Tongs: These blacksmithing tools are used to elevate the metal pieces out of ” forge” and clutch it during the process. The more random grain structure found in standard cast wheels becomes a more highly organized and aligned grain structure when wheels are forged.  http://www.jo-pv.com/
