Oil Burner修理维护

严重警告:


本文仅供参考。
Oil Burner修理维护过程涉及燃油、高压点火电压。请适当评估危险系数,把Oil Burner修理维护工作留给专业人士。
如果自己动手造成后果自负!!!


感谢网友Sean提供咨询帮助!!!



烧油的炉子出问题了。


症状:burner开始能自己点火启动,能闻到油味儿。之后越来越严重。最后炉子不能自己启动。
摁reset button,可启动,观察火焰不持续,燃烧几分钟后熄灭,并有浓重的油味儿。


基本诊断:



1)点火变压器(transformer)应该没问题。
2) cad cell sensor (flame sensor)应该没问题。
3)基本判断是进油的问题。开始清理喷油嘴(nozzle).

最后更换了oil filter,问题得到解决。

结论:oil filter建议每年都换。

 oil burner出火不持续是啥问题?喷油嘴脏了?

我的burner可能要换fuel pump了

刚才清洗了油嘴。

Oil Filter

Filter housing (4 inch 左右直径)

Home depot店里有。早上去买一个。/::D

which one in stock at HD?

RF4B/RF4

looks like the right one. I recommend you buy both types that I gave links for, just in case, pick one to use.

1. Shut off oil supply before the filter

2. Loosen the single bolt on the top, filter housing will drop down

3. Replace filter and all 3 gaskets

4. torque the bolt to 10 ft.lb

5. Bleed the line


右下角是bleed connect fitting?

4-5 o'clock

6 o'clock shinny one

和bleed刹车油一样?

4 o'clock in my picture

similar, except that, in oil furnaces' case, the pressure is constantly positive so there's no risk of suck-backs

这是oil burner 原理图






炉子外貌




Beckett (炉子的牌子)


Reset button (及控制电路)



动手之前关掉电开关


打开transformer

严重警告:就算断了电,transformer可能会带高压(高压!!!!)就是图中两个弹簧状触点。

中间黑色的管状物就是 cad cell sensor (flame sensor)




(左边fuel pump进油和进空气, 右边是进入炉膛的电极和油管)



喷油点火系统
(中间是进油管,两根金属柱是接点火高压线圈的)


这就是喷油嘴(nozzle)


临时手边有修车的东西就代用了(清洗碳的东西应该都可以)





这是oil filter housing (更换filter的步骤再贴一次):


1. Shut off oil supply before the filter

2. Loosen the single bolt on the top, filter housing will drop down

3. Replace filter and all 3 gaskets

4. torque the bolt to 10 ft.lb

5. Bleed the line







这是fuel pump。更换filter之后bleed使用的嘴就在4·5点钟位置。
(bleed过程就是拧松bleed fitting,摁reset启动炉子,等bleed 口流出持续的油用合适的容器盛接,再拧紧关上即可)



最后总结一下

@Sean 已经说了:

 tune up 包括五样:filter change, combustion chamber sweeping, nozzle cleaning, air filter change, test run
