How can you achieve constant air pressure with air compressor?
By the use of a tank and a regulator. The compressor discharges into the tank, where the pressure can vary but is always higher than the desired pressure. The tank feeds the regulator which delivers the desired pressure. Alternately, you might be able to size or modify the compressor to meet the load exactly with a 100% duty cycle, but that is less practical.
What does a compressor do on a car?
An AC compressor compresses the freon and circulates the freon through the system.
An air ride compressor pumps compressed air into air bags to level the vehicle and/or alter the handling of the vehicle.
Can you add an AC compressor to a 1989 Chevy k2500?
Yes. Look in the yellow pages for aftermarket a/c's
yes
What is the typical thermal adiabatic efficiency of a sliding vane compressor?
In discussing adiabatic efficiency, it is best to first define efficiency. In its broadest terms, efficiency can be defined as the ratio of work output to work input normally expressed as a percentage. With regard to a compression application, one measure of the efficiency of a compressor is the adaibatic efficiency (Volumetric Efficiency being the other). Adiabatic Efficiency is the ratio of the amount of horsepower required just to compress a particular gas (Adiabatic Horsepower) divided by the total brake horsepower required for a praticular type of compressor to accomplish the desired compression. Note that Adiabatic Power is the same regardless of the type of compressor used because it is a function of the physical properties of the gas being compressed, and not the type of compressor doing the work. In other words, it takes a specifc amount of energy to compress a specific volume of gas to a particular pressure and this energy is the same no matter what technology you use to accomplish the compression. Adiabatic HP is the numerator of the equation and is the same no matter what kind of compressor is used.
The denominator of the equation is total brake horsepower (BHP) and it is the total power required for a compressor to accomplish the desirder compression. This will be a larger number as BHP includes adiabatic power plus all the other energy required by the compressor to overcome other losses requiring energy such as drive losses, mechanical friction losses, intake/discharge valve losses, heat exchanger losses, lubrication system power, etc.
Therefore, to answer the question specifically would require information on the specific gas being compressed, flow, pressure, atmospheric conditions, etc. To answer the question in general terms, the rotary vane type compressor will typically have a higher adiabatic efficiency than screw compressors and reciprocating compressors by virtue of the fact that other losses from friction, lube systems, valves, etc. which tend to be significant with screws and recips are not substantial and sometimes not present at all with vane technology. As such, vane compressor total BHP is normally lower than other technologies resulting in higher adiabatic efficiency. Another reason vane machines often have higher adiabatic efficiency is that they are limited to a maximum compression ratio of approximately 4.5 to 1, (depending on the type of gas and the application requirements). As is documented in Marks' Standard Handbook for Mechanical Engineering, as compression ratio increases, both adiabatic efficiency and volumetric efficiency decrease on screws and recips. Therefore, for discharge pressures up to approximately 125 psig, the vane technology, even in a two stage system, will likely be more energy efficient than other compression technologies.
The above is a broad answer to a specific question and the degree to which the efficiency is greater (or not) will vary with the specifics of the application. Adiabatic efficiency is however, a good measure of efficiency and a good indicator of how energy efficient equipment will be once in operation. All the compression technologies mentioned are viable and proven and some are better suited than others depending upon the specifics of the application. For example, as noted above, the vane machine is well suited for relatively high flows and for compression up to about 125 psig. For processes requiring compression above 125 psig discharge pressure, the vane technology is not suitable and screws or recips are likely the more appropriate technologies. Finally, in addition to power cost, buyers should also other factors that impact the cost of ownership such as parts, service, and maintenance requirments when considering compression equipment.
Tire Pressure for Hyundai Accent?
There is a label on the door jamb that shows the tire pressure recommendations. Between 32-35psi is what I put in my tires.
Is an Air Compressor and an unfired pressure vessel the same thing?
A compressor increases the velocity of incoming air/gas and then converts this velocity energy into pressure energy. Using multi-stage compressor the pressure can be increased manifold. Most common compressor is the centrifugal type where air/gas is energized to high energy velocity by a rotating disc and impeller. A divergent duct then converts this high velocity air/gas into high pressure air/gas.
A compressor is not a container or a vessel and as such it does not store pressurized air/gas and hence cannot be termed as a pressure vessel. However to store and utilize this high pressure air/gas, an air receiver is connected to it through pipe and valves which stores such high pressure air/gas. This air receiver is a pressure vessel.
Air receiver which is a pressure vessel is subjected to periodic examination by a government certified competent person whereas compressors only need routine and preventive maintenance by inhouse engineers. The Factories Act and the Rules thereunder are very specific about this and has clearly mentioned such distinction.
What does an air conditioner compressor do in a 2001 Honda?
it breaks. like mine has been for the past three years. therefore, the a/c doesnt work and it needs to be replaced. i love it. the transmission also enjoys to die.
Green dye from air compressor in jeep?
Without any further information than this I'm going to take a stab at this question. First, by saying air compressor, do you mean the blower that sends cold or hot air into the Jeep from the vents or do you have some kind of aftermarket air compressor? What year Jeep is this?
My guess would be that you are seeing a fine mist blowing into the Jeep and that it's more than likely antifreeze coming from a leaking heater core in the evaporator box for the climate control system.
I don't know much about late model Jeeps but I wouldn't be surprised if there's a factory installed air compressor option that would have a compressor in the engine compartment with air hose connections inside the rear liftgate for inflating innertubes etc. If that's the case the dye that you're seeing is more than likely compressor oil leaking into the air lines.
What is bumping clearance in marine air compressor?
It is normal practice ot make a check on the clearance volume of an air compressor as this is something which is fixed by the designer. We do however make a careful check on the mechanical clearance between the piston head and the cylinder cover. This check is made by making a small woven ball of elad wire, which is placed on the top of the piston, which will have been moved a little off the end of the stroke. The cylinder cover is replaced on the cylinder with a joint in place and tightened down. The compressor is then barred slowly over top centre so that the ball of the lead wire is compressed. After it is removed from the top of the piston, it can be measured with a micrometer. The mechanical clearancde measured is compare with the manufacturer's receomemndations. Adjustments are made by altering the cover joint thickness or by fitting or removing shims between the foot of the connecting rod and the bottom end bearing. This clearance varies widely according to cylinder diameter, runing speeds and final discharge pressures.
How do you repair a failed 1991 Lincoln Town Car air suspension compressor?
The compressor is located in a compartment in the left front wheel hub. To access it you have to remove the air cleaner and the washer fluid reservior.
Can the compressor clutch air gap be adjusted without removing the compressor on a 1996 Odyssey?
I am not 100% sure, but I do not believe the air gap can be adjusted on that compressor. Manufacturers use washers/ shims to set the air gap, and to adjust it, you would need to pull off the hub and check the shims (start with pulling only one off).
How you remove a compressor from a 97 Pontiac Grand Am?
you have to take it to a shop that can professionally drain the refrigerant from the compressor. It is very hazardous stuff and CAN NOT be drained into the air, it has to be captured. Then you just have to unbolt the compressor. You may have to remove the radiator first.

On a vehicle with a compressor with a cycling clutch, yes.
How do you replace air conditioning compressor on a 1987 Fiero?
Reclaim the freon from the 1987 Fiero. Remove the ac belt, then disconnect the lines from the compressor. Unbolt the compressor then bolt in the new one. Put the hoses and belt back on, then pull a vacuum on the system before filling with new freon.
What air compressor do you need to remove lugnuts off your truck?
Any air compressor that can achieve and hold 100psi will run an air gun. the larger the tank the more lugs you can remove before the compressor will need to run again.
How much copper in a 100 HP electric motor 100 HP electric Chicago air compressor motor?
The amount of copper in a particular motor is not determined by horsepower only, there is no relationship between the total weight of MAGNET WIRE to the HORSEPOWER of an electric motor.
Determining factors are the vintage, frame, make, speed, and frame designation.
The proper suction pressure of any air conditioning or refrigeration system is determined by the type of refrigerant used and sometimes the amount of charge. : Suction pressure used is also directly related to the temperature required. : The temperature required in the evaporator relates to the pressure required in the suction line since, the fluid is at saturation in the evaporator. : Knowing the temperature required, use the fluid's saturation tables to find the corresponding pressure required.
What is meant by loading and unloading in air compressor?
In an air compressor, there are devices that automatically stops the compressor from compressing air. A mechanical unloader is sometimes installed in large air compressors such that air valves are open when the set pressure is attained. When this happens, the drive motor continues running but no air pressurre is pumped to the receiving tank during the unloading period. When the pressure in the tank is reduced to a set level, the air valves in the compressor automatically closes and air pressure is again developed, this called pressure loading. In many oinstances, compressors are contolled only by pressure switches to automatically stop the drive motor at a set pressure and restart at a lower pressure.
Why flywheel is used in reciprocating compressor not in centrifugal compressor?
Flywheel prevents fluctuation in the speed of the motor as a result of load fluctuation. It stores the energy and dissipates it to the compressor for prolonged period. So the load fluctuation which is high during compression stage and low during other stages during a cycle in reciprocating compressor gets nullified. On the other hand, centrifugal compressor continiously compresses the gas and does not have load fluctuations, hence flywheel is not required.
