T1
|
Measuring point for a compressor's acceptance test; temperature at the
compressor inlet flange. |
T3
|
Measuring point for a compressor's acceptance test; temperature before an
orifice or nozzle, downstream of compressor discharge. |
Temperature
|
The property of a substance that gauges the potential or
a driving force for the flow of heat. |
Temperature, Absolute
|
The temperature of air or gas measured from absolute
zero. It is the Fahrenheit temperature + 459.6 and is known as the Rankine temperature. In the metric system, the absolute temperature is the
Centigrade temperature + 273 and is known as the Kelvin temperature.
|
| Temperature Discharge |
The temperature existing at the discharge port of the compressor.
|
| Temperature, Inlet |
The total temperature at the inlet connection of the
compressor. |
| Temperature Intake |
The total temperature at the intake flange of the compressor. |
Temperature Rise Ratio
|
The ratio of the computed isentropic temperature
rise to the measured total temperature rise during compression. For a
perfect gas, this is equal to the ratio of the isentropic enthalpy rise to
the actual enthalpy rise. |
Temperature, Static
|
The actual temperature of a moving gas stream, which is the temperature
indicated by a thermometer moving in the stream with the same velocity as
the stream. |
Temperature, Total
|
The temperature which would be measured at the stagnation point if a gas
stream were stopped with adiabatic compression from the flow condition to
the stagnation pressure. |
Theoretical Power
|
The
power required to compress a gas isothermally through a specified range of
pressures. |
Thermal Compressor
|
An
ejector used to compress waste or exhaust steam or any other gas through a
moderate range of compression above atmospheric pressure. |
Thermal Mass
|
Material that stores energy (mass also retains coolness); the thermal
storage capacity of a material is a measure of the material's ability to
absorb and store heat. |
| Thermodynamics, First Law
Of |
The amount of work performed on or by a system is equal to the amount of
energy transferred to or from the system. |
| Thermodynamics, Second Law
Of |
Heat cannot, of itself, pass from a colder to a hotter body.
|
Thrust Balancing Device
|
The part of a rotating element that counteracts any inherent thrust
developed by the impellers. |
| Tilting Pad |
A type of
journal bearing in centrifugal air compressors. |
Torr
|
A unit of pressure
used with vacuum pumps, equal to 1mm of mercury and 133.32 Pascal's.
|
Total Package Input Power
|
The total electrical power input to a compressor, including drive motor,
cooling fan motors, VSD or other controls, etc. |
Torque
|
Torsional moment or couple, which usually refers to the driving couple of a
machine or motor. |
Trunk Compressor
|
A
compressor belonging to the group of displacement reciprocating compressors.
|
| Trunnion |
A device for
mounting cylinders. |
| Tugger |
An air operated device for hoisting or pulling similar to a slusher or
winch. |
Tundish
|
A receptacle, open to atmosphere, that is used to collect
condensate. For example, two or three drain pipes from various filters may
be discharging into a funnel. In this case the funnel is a tundish. |
Two Stage Compressors
|
Machines in which air or gas is compressed from initial pressure to an
intermediate pressure in one or more cylinders or casings. |
Two Step Control
|
A load/unload control system that tries to maximizes compressor efficiency by
matching air delivery and air demand with the compressor operated at full
load or idle. |
| TXV Valve |
A thermal
expansion valve. |
