Here are some more information for Manifold Stainless:

The rotary screw belongs to the positive displacement compressor family. Positive displacement pumps create flow by applying an expanding cavity on the suction side and a decreasing cavity on the discharge side. Gas that is trapped inside the positive displacement machine is a fixed volume which is then compressed or displaced into the discharge manifold.

The two most commonly used compressors today are the rotary screw (helical rotor) and the reciprocating piston. In comparison of the two, the rotary screw does not use valves, is lighter in weight than the reciprocating piston, is pulsation free making foundation requirements less extreme and maintains its design efficiency over operational time as the rotors never come in contact with each other. The screw compressor was originally designed in the mid 1950's and eventually developed to operate between the reciprocating piston and centrifugal machine capabilities for commercial, industrial and gas type applications.

The Rotary screw compressor is composed of two intermeshing helical rotors contained in a housing. Clearance between the rotors and between the housing and the rotors is typically .003" to .005". The male or drive rotor is connected through a shaft extension by an electric motor or engine. In the case of an oil injected machine, the female rotor is driven by the male rotor through a thin film of oil. A dry rotary screw compressor employs a set of timing gears to achieve proper rotation.

The diameter and length of the rotors regulate the final pressure and capacity the machine can produce. As the rotor diameter increases, so does the air pumps capacity; As the length of the rotor increases, so does the pumps final pressure.

As power is applied to the male rotor it begins to move out of mesh with the female rotor creating a void allowing gas to be drawn in through the inlet port. As the rotor maintains past the inlet port the intermesh space continues to expand until the gas completely fills the interlobe space. When the male rotor enters the interlobe space it begins to convey and compress the gas towards the discharge port. As the rotors turn the gas filled grooves are isolated by the housing walls, creating a compression chamber, where lubricant is then injected to provide cooling, sealing and lubrication.

Continued rotation causes the gas volume to reduce to the stated design pressure. The compressed gas and lubricant is finally sent through the discharge port, then into a two phase separator where the oil and gas are divided. The oil is filtered by a 10 micron automotive type spin on filter and then cooled via air or water before being re-injected into the compression chamber. The oil type used in these machines is a hydrocarbon synthetic of ISO 100, 150 or 220 viscosities and is selected based upon specific gravity of the gas. Proper gas analysis is critical in oil selection as during initial start up, gas will dilute the viscosity of the oil. In the case of an air compressor the gas is then directed to an air cooled after-cooler where up to 70% of the ingested water vapor is condensed out of the gas stream before entering the supply manifold.

The compression porting is located and cut to attain the application pressure ratio. To achieve the greatest efficiency, it's central the corresponding geometry match the application pressure requirements. Some rotary screw compressor designs employ a variable discharge valve that continuously seek maximum efficiency by opening and closing depending on system pressure conditions. When the compressor senses a decreased system air demand (rising pressure) the discharge valve allows air to circulate back to the inlet without being compressed to meet system demand. The net effect is a shorter length rotor resulting in variable displacement operation allowing power requirements to drop.

The displacement of the screw compressor is a function of the interlobe volume and speed. The interlobe volume is a function of rotor profile, length and diameter. The interlobe volume can be expressed by the equation;

Qr = d3 (L/d) / C

Where:

Qr = Displacement/Revolution

d = rotor diameter

C = typical profile constant

Qd = Qr x N

Where:

Qd = discharge volume

N = compressor speed

Qi = Qd x Ev

Where

Qi = actual inlet volume

Ev = volumetric efficiency

Volumetric Efficiency is a function of rotor slip which is the internal leakage created by gas expansion back to the low pressure side therefore reducing the potential volume capacity of the compressor.

The screw compressor discharge temperature can be evaluated assuming adiabatic compression, assumes no energy (heat) is transferred to or from the gas during the compression and all supplied work is added to the internal energy of the gas resulting in increase of temperature and pressure.

Discharge temperature can be calculated by taking the adiabatic temperature rise and dividing by the adiabatic efficiency, and then multiplying by the temperature rise efficiency to account for cooling. To find the final discharge temperature, add the inlet temperature to the temperature rise.

t2 = t1 + T1 (rpk-1/k-1) / na x nt

Where:

rp = pressure ratio

na = adiabatic efficiency

nt = temperature rise efficiency

Hho Generator Can Increase the Power of Your Car Dramatically

The term Water Car can be understood in two ways. 1) A water car that rides on water and 2) A water car that runs on water, but as a fuel. This article talks about using water as fuel for car. It sounds fascinating isn't it? Well, thanks to the technology that has brought water cars into existence. You can now have car fitted with an on board HHO generator which generates HHO gas to be fed into the engine manifold along with regular gasoline / petrol. The benefits of these kinds of water powered cars are that you get increased mileage, more power, less pollution and above all your cars engine stays much cooler.

Initially, water cars were popular only in Europe. However, you can now find water cars in USA and other parts of the world too. This is possible due to the awareness about the water car and thus creating a demand and supply like situation which also reflects on the selling price of a water car. Also, technology has brought in, intelligent and long lasting parts for the water car.

With a water car, you can experience the thrill and excitement of driving vehicles at high speed and that too in the water. This is all happening due to the coming of new technology which makes a whole new mode of transportation possible.

How does water fueled car works?
Your car can now be fueled by using water. It can be done when water is used as a supplement to gasoline. Yes, you can now convert your car to run on water and gas. This technology of using water as car fuel has been around since many years. However, recently, the concept of using water as car fuel has started getting more attention. These days there are water conversion kits available. You can use this kit to convert your car to run on water and gas. You can save about 40% on fuel costs. It also helps to improve the ecological balance.

When you use water as car fuel, you automatically improve the survival of life, called oxygen. The running car that is fueled by water leaves out oxygen and water vapor or steam. When condensation takes place, the water vapor quickly condenses back into water. This action helps to replenish the oxygen in our atmosphere. This is the main benefit for switching to water as car fuel.

Water conversion do it yourself kits are now available which teach you to use water as car fuel. You can use tap water as car fuel. So, no need for any distilled water or any kind of special water. The conversion kit cum guide teaches you how to use electricity from your car's battery in order to separate water into a gas called HHO ( 2 hydrogen + oxygen. The other name for HHO is called Brown's gas or Hydroxy. It has a smooth burning effect and provides effective energy. At the end, you get H2O. The atomic power of hydrogen is provided by HHO and at the same time it maintains the stability of water.

One must understand that you cannot use water entirely as car fuel. You will have to use gasoline too. But the main point that has to be kept in mind is that you can save much money on gas if water is used as a supplementary car fuel. Also, the after effects of using water as car fuel, helps the environment in a great way.

Pipe bending for exhausts intakes manifolds and roll cages ???

I was wondering if there was any cheaper manual/hydraulic type benders out there that would give me decent bends with out the inside of the bend flattening out or wrinkling? I am hoping not to spend over a couple hundred bucks on a bender so obviously theres no way i could afford a mendrel bender or anything, but I would like to get info from anyone else that has or does bend pipes and knows of a way to make decent quality bends in a fairly cheap way. I do want to be able to bend up to a 3" pipe with different thicknesses using stainless and aluminum. I am guessing the thinner intake pipes I want to bend will have the most distortion when bending. I know even a mendrel has a very slight distortion, but in my case I just want to get the least amount of distortion in the bends at a reasonable price. So is there any ways of doing this? certain tools/benders I should look into? Any advise from someone that actually does pipe bending would be appreciated, thanks

Unless you have a computerized bender that can be programmed to bend a specific piece or length and gauge of pipe a specific way then it's all trial and error as you custom fit each piece.

A muffler shop with one of those higher priced benders can do it but it's time consuming and you'd have to piece it together. The sharper the bend the more likely there will be inside wrinkles.

They sell the old manual hand cranked benders. Might check at Harbor Freight Tools for a Made in China bender at a decent price.

Good Luck!
