根據百分之百之流量係數，設若進口極圓時，則以 0.97 乘以值，設若為一銳緣孔口時，則乘數用
0.65。
此表僅能產生近似之結果，若欲作精確之測量，則請見 ASME 動力試驗規格流動容積速度之測量。
1 至 15psig
壓力值之計算，係使用標準絕熱公式。
超過 15psig 壓力值計算，係使用此近似之公式： w=0.5303acp./( √ T )。其中 w=
每秒排出之磅數，a= 孔口面積，平方吋，c= 流量係數，p= 上流總壓力，psia，T= 上流溫度，F 絕對。
上述情況值之計算係 c+1.0 , p=
錶壓 +14.7psia , T= 530F 絕對。
重量數改為容量時，則使用每立呎 0.0749 磅密度因素，此係用於 14.7psia 則此 70F
乾空氣之修正。
此公式不能用於 p ，少於兩倍大氣壓。 |

On thc basis of a 100% flow coefficient, supposc that the inlet
is extremely round, then multiply the value by 0.97; if the aperture has knife
edge, multiply them by 0.65.
We can obtain only approximate results here.
Fore accurate mcasurement, refer to measurement of flow volume speed in ASME
Power Experiment Specifications.
The standard thermal insulation formula is
used in computation of pressure values between 1 and 15 psig.
For the
computation of pressure values over 15 psig, the following approximate formula
is used : w= 0.5303acp./( √ T ),in which w= delivered pounds/sec, a= aperture
area( in2 ), c= flow coefficient, p= upstream gross
pressure (psia), T= upstream temperature ( °F absolute).
In the above cases
of computation, c= 1.0, p= gauge pressure +14.7 psia, T= 530°F absolute.
When
weight is subtituted by volume, the density factor of 0.0749 lb / ft3 is used instead, which is for 14.7 psia. So the 70°F is dry air
correction.
Thc formula is not applicabie for p less than twice the
atmospheric pressure. |

空壓機馬力適用於冷卻水塔對照表
Air Compressor System
Planning Guideline ： |
| 一. 壓力之決定： |
- 壓力越高，耗電越大。須考慮配管尺寸大小及長度所造成之壓力降，加上使用壓力 即為最下限之壓力。
- 列出各種機械之使用壓力，如使用壓力相差太多時，則須購置不同壓力之空壓機或使用增壓機，不可降低壓力使用，增加電 費之出。
|
| Operation pressure： |
- The higher operating pressure, the more power consumed.The minimum operating
pressure is the working pressure plus the piping loss.Selection of adequate pipe
dimension and arrangement should be taken into account.
- List required pressure needed of all application for proper compressor
selection. If working pressure range is too large, multiple compressors with
different working pressures or boosters should be used.Do not regulate high
discharge pressure to lower discharge pressure because it will waste energy.
|
| 二.場地： |
- 須寬闊採光良好之場所，以利操做保養。
- 溫度低、灰塵少、空氣清淨且通風良好之 場所，室溫應低於 40°C 以下。
|
| Site selection： |
- Location should have adequate spacing and be well lit for ease of
maintenance.
- Choose a location with low humidity,minimal dust clean air, and good
ventilation with room temperature lower than 40°C .
|
| 三. 冷卻水與水質： |
- 冷卻水水溫宜低，配合冷卻水塔做冷卻。
- 應注意冷卻水之PH值，應維持在7左右， 以防結垢，增加清理費用。
- 應注意冷卻器之冷卻效果，一般而言壓縮 空氣出口溫度應約在 42°C 左右。
|
| Cooling water： |
- Low temperature cooling water is preferred. A cooling tower is recommended.
- Pay special attention to the PH factor of cooling water.It should be kept
around 7.0 to prevent the scale from clogging the copper tube saving maintenance
expense.
- Pay attention to the heat exchanger's performance.Generally speaking,air
outlet temp. of compressed air should be about 42°C
|
| 四. 機型之選擇： |
- 計算出總實際使用風量再加上裕量為宜。
- 本公司型錄所列之實際排氣量，皆依美國 ASME測風量設備加以測試證明。
- 注意耗能比值，以求省電。
|
| Model selection： |
- Air delivery shown in our catalog meets code specified by ASME.
- Add some allowance to the actual consumption you calculate.
- Pay attention to compressor's specific power consumption to save energy.
|
| 五. 壓縮空氣品質與要求： |
- 壓縮空中含有 100%
相對濕度的大量水分，它對精密儀器、氣動工具、氣動設備、閥、儀錶、管路等造成莫大的傷害，因為水分會造成銹蝕、堵塞儀器、降低成品品質、損壞設備而且損失大量的金錢於修理維護工作，所以加裝壓縮空氣清淨系統確有其必要。如下圖：
|
| The quality and requirement of compressed air ： |
- The compressed air before condensation contains saturated water vapor which
will damage precision instruments,pneumatic
equipment,instrumentation,piping,etc.For fear of corrosion,clogging, low air
quality,damage to apparatus and increased maintenance cost,it is necessary to
install an air filtration system as shown below ：
