OXY-PILOT®全氧助燃點火管路

OXY PILOT

MAXON OXY-PILOT® 全氧助燃點火管路用于MAXON OXY-THERM® LE 燃氣燃燒器或標準 OXY-THERM® 工業(yè)燃燒器，熱量輸出zui高達7.3kW的。

如采用OXY-PILOT®，可*實現(xiàn)燃燒器的自動化運行，無需助燃空氣設備投資，同時也節(jié)省了點火器的投資成本。

電磁式
電磁式直流電動機由定子磁極、轉子（電樞）、換向器（俗稱整流子）、電刷、機殼、軸承等構成，電磁式直流電動機的定子磁極（主磁極）由鐵心和勵磁繞組構成。根據其勵磁（舊標準稱為激磁）方式的不同又可分為串勵直流電動機、并勵直流電動機、他勵直流電動機和復勵直流電動機。因勵磁方式不同，定子磁極磁通（由定子磁極的勵磁線圈通電后產生）的規(guī)律也不同。
串勵直流電動機的勵磁繞組與轉子繞組之間通過電刷和換向器相串聯(lián)，勵磁電流與電樞電流成正比，定子的磁通量隨著勵磁電流的增大而增大，轉矩近似與電樞電流的平方成正比，轉速隨轉矩或電流的增加而迅速下降。其起動轉矩可達額定轉矩的5倍以上，短時間過載轉矩可達額定轉矩的4倍以上，轉速變化率較大，空載轉速甚高（一般不允許其在空載下運行）?？赏ㄟ^用外用電阻器與串勵繞組串聯(lián)（或并聯(lián)）、或將串勵繞組并聯(lián)換接來實現(xiàn)調速。
并勵直流電動機的勵磁繞組與轉子繞組相并聯(lián)，其勵磁電流較恒定，起動轉矩與電樞電流成正比，起動電流約為額定電流的2.5倍左右。轉速則隨電流及轉矩的增大而略有下降，短時過載轉矩為額定轉矩的1.5倍。轉速變化率較小，為5%~15%?？赏ㄟ^消弱磁場的恒功率來調速。
他勵直流電動機的勵磁繞組接到獨立的勵磁電源供電，其勵磁電流也較恒定，起動轉矩與電樞電流成正比。轉速變化也為5%~15%。可以通過消弱磁場恒功率來提高轉速或通過降低轉子繞組的電壓來使轉速降低。
復勵直流電動機的定子磁極上除有并勵繞組外，還裝有與轉子繞組串聯(lián)的串勵繞組（其匝數(shù)較少）。串聯(lián)繞組產生磁通的方向與主繞組的磁通方向相同，起動轉矩約為額定轉矩的4倍左右，短時間過載轉矩為額定轉矩的3.5倍左右。轉速變化率為25%~30%（與串聯(lián)繞組有關）。轉速可通過消弱磁場強度來調整。
換向器的換向片使用銀銅、鎘銅等合金材料，用高強度塑料模壓成。電刷與換向器滑動接觸，為轉子繞組提供電樞電流。電磁式直流電動機的電刷一般采用金屬石墨電刷或電化石墨電刷。轉子的鐵心采用硅鋼片疊壓而成，一般為12槽，內嵌12組電樞繞組，各繞組間串聯(lián)接后，再分別與12片換向片連接。

Installation and Start-up
• The pilot is shipped “cleaned for oxygen service.”
The spark gap is factory-set. Never attempt to
disassemble the pilot.
• Install the pilot by the NPT threads in the burner
housing of the OXY-THERM® LE, or with the bolton
pilot adapter when used on the Standard OXYTHERM
®.
• When threading in the pilot, do not use a pipe
wrench on the tee section; use the stainless nipple
instead. Take care not to damage the stainless fuel
tube when making the connection.
• The 3/16" compression fitting can be removed for
1/8" NPT connection, if preferred. The Swagelock
nut should only be tightened three-quarters of a
turn from finger-tight.
• Refer to the Capacity and Specification chart on
the previous page for recommended pressures and
flow rates.
• Spark should be constant only until the pilot lights.
• Pilot operation should always be interrupted when
used with either the OXY-THERM® LE or Standard
OXY-THERM® Burners. Failure to do so will result
in imbalanced main burner flame and accelerated
degradation of the refractory block.
• Cooling oxygen must be used when the pilot is
installed in a high temperature atmosphere and
the OXY-THERM® Burner is not firing.
• The proper sequence for igniting the pilot is: Spark
on, Oxygen on, Fuel on (ignition occurs), Spark off.
At this point, the main OXY-THERM® Burner can
be ignited. If the burner is not going to be ignited
within a few minutes, the pilot should be interrupted
to extend refractory life.
