Does an overcharge of refrigerant affect suction pressure?
In a simple system with a fixed orfice expansion device for example, an overcharge will increase suction and head pressure. Compressor amps will also increase. Overall refrigeration capacity will be reduced. lc
What is definition of high head pressure in a air conditioner?
High head pressure is due to the lack of heat removal during the condensing process of the refrigerant cycle. The outdoor condenser is there to transfer the heat out and condense the refirgerant into a liquid. When ever the condenser is dirty or the fan motor is not working right the result is an increase in temp. and since pressure and temp are directly related the refirgerant pressure is increased thus the term high head
Why pressure is inversely proportional to velocity in bernoulli's equation?
Usually in a streamlined motion the sum of three heads have to be constant always. They are pressure head velocity head and gravitational head In case of horizontal pipe gravitational head is already a constant Now velocity head + pressure head = constant So as velocity head increases then automatically pressure head has to fall.
What is head to tail rule?
A and B is a vector by replacing the tail of the B on the head of the A and the join the tail of the A with the head of the B this method is called head to tail rule
What is the difference between the head and the skull?
the difference between a head and a skull is that a head has tissue and a skull is all bone
Does compressor work more efficiently with an increased head pressure?
It depends on other conditions too. There is a net suction head, which is the pressure from which the compressor is drawing the gas. An increase here will often improve the compressor's efficiency. There is also a net discharge head, which is the pressure the compressor is trying to maintain. An increase here will often decrease the compressor's efficiency. There is an efficiency curve for all compressors, and they are all different based on their design, it is dependent on the differential pressure (NDH - NSH) and load (air flow in SCFM, typically) of the compressor, at a certain load the efficiency peaks then drops as the load increases.
What happens if you faint for no reason?
their must be a reason. the air probually couldn't get to your head or your blood preassure dropped rapidly.
Is poor compressor can cause high head pressure in an air cooled condenser?
Poor compressor performance should result in low head pressure as the system cools better than the compressor can pump.
What is compressor head as it relates to discharge pressure?
the head doesnt effect the output pressure of a compressor package but the size of the piston and the amount of clearence and volume between the piston and head changes your output psi
Where is the compressor on the Pontiac Grand Am?
behind the head lights
What is compressor turndown?
Turndown: The allowable operating range for the centrifugal compressor between the design point and the surge line at any given speed for a fixed compressor head.
If compressor has faulty valves the head pressure would be?
broken
If a compressor has faulty valves the head pressure?
the pressure would be low
looking for a head gasket quincy 160 compressor part # victor #3415 its an old jack hammer compressor ?
Try http://www.victorreinz.com/products.html, they offer a variety of head gaskets, which are still in production for older models.
Is it unusual for a 2001 Trooper with 93000 miles to lose an oil pump and damage the lower end?
i am assuming u are talking about a 3l diesel some tines the oil pick up pipe falls into the sump but it wont damage the lower end cause the engine wont run without oil preassure it needs preassure at the fuel rail in the head to run . so i have never seen one doing damage to the crank and i work on them all the time i am assuming u are talking about a 3l diesel some tines the oil pick up pipe falls into the sump but it wont damage the lower end cause the engine wont run without oil preassure it needs preassure at the fuel rail in the head to run . so i have never seen one doing damage to the crank and i work on them all the time
Why is there too much pressure in cooling system in Detroit 60 series?
Bad head gasket or cylinder head. Suggest to check air compressor before working on the head.
Why did the air compressor quit turning?
Seized? Low freon charge? High head pressure?
