焦化发电机组可以作为许多行业的电力保障，可是很多用户对于焦化机换季维护方面知识很陌生。正确维护焦化机， 可提高使用寿命。小编帮您了解关于焦化发电机组在换季时的需要注意的一些事项。

The coking generator unit can be used as the power guarantee for many industries, but many users are unfamiliar with the knowledge about the maintenance of the coking machine. Correct maintenance of the coking machine can improve the service life. The editor will help you understand some matters needing attention during the season change of the coking generator unit.

一．旋转机油指示器

1、 Rotary oil indicator

凡在润滑油路中（装在滤清器处）刻有“冬、夏”两档旋转指示器的焦化机，将指示箭头对准“夏”字，实现机油大 循环；可有效避免机油温度过高而导致机油压降低，从而能够降低机件磨损。

For the coking machine with "winter" and "summer" rotary indicators engraved in the lubricating oil circuit (installed at the filter), align the indicator arrow with the word "summer" to realize large-scale oil circulation; It can effectively prevent the oil temperature from being too high and the oil pressure from decreasing, thus reducing the wear of the parts.

二.卫生大扫除

2、 Clean up

摘去保温被，对焦化机进行一次卫生大扫除。清理泥土、杂物、油垢，给机器地洗一次脸。在清理、清除、清洗 过程中，可以发现松动的螺母、铆钉及外表缺损处，要及时更换修理。

Remove the thermal insulation blanket and conduct a sanitary cleaning of the coking machine. Clean the dirt, sundries and oil stains, and wash the face of the machine once. Loose nuts, rivets and external defects can be found during cleaning, removal and cleaning, and shall be replaced and repaired in time.

三.清洗三滤、三网

3、 Clean three filters and three nets

空气滤清器、焦化过滤器、机油滤清俗称三滤。清洗三滤主要注意的是：

Air filter, coking filter and oil filter are commonly known as three filters. The main points for cleaning the three filters are:

①三滤是纸质滤芯，除空滤器滤芯清扫后可用外，其余建议更换新品。

① The third filter is a paper filter element. It is recommended to replace it with a new one except that the filter element of the air filter can be used after cleaning.

②金属滤网、滤芯的，只能用干净油、毛刷或气筒进行清洗，用气体吹出脏物，切不可火烧。“三网”指焦化加注口 、机油加注口、废气排除口的过滤网，应清洗，以使进出畅通无阻。

② The metal filter screen and filter element can only be cleaned with clean oil, brush or air cylinder, and the dirt can be blown out with gas. It is not allowed to burn. "Three nets" refer to the filter screens at the coking filler, engine oil filler and exhaust gas outlet, which shall be cleaned to ensure smooth access.
