天然氣發電機組中的碳刷材料的特性

天然氣發電機組碳刷架中的碳刷的資料大多由石墨制成,為了增加導電性,還有用含銅石墨制成,石墨有良好的導電性,質地軟而且耐磨。

D88尊龙The data of carbon brushes in the carbon brush holder of natural gas generating units are mostly made of graphite. In order to increase electrical conductivity, graphite brushes are also made of copper and graphite. Graphite has good conductivity, soft texture and wear resistance.

天然氣發電機組碳刷架中碳刷能夠用于直流電機或交流換向器電機,比方通用電開工具上,象手電鉆和角磨機上,皆用到它。他是用來和換向器配合來完成電機電流換向的。

D88尊龙The carbon brush in the carbon brush holder of natural gas generator can be used for DC motor or commutator motor, such as general electric tool, hand drill and angle grinder. He is used to match the commutator to complete the commutation of the electric current.

天然氣發電機組碳刷架中碳刷是電機配件(除鼠籠式電動機外)傳導電流的滑動接觸體。在直流電機中,它還擔負著對電樞繞組中感應的交變電動勢,停止換向(整流)的任務。理論證明:電機運轉的牢靠性,在很大水平上決議于電刷的性能。

The carbon brush in the carbon brush frame of the natural gas generator set is the sliding contact of the electric current of the motor parts (except the squirrel cage motor). In a DC motor, it is also responsible for the task of changing the alternating electromotive force of the armature winding and stopping the commutation (rectifying). The theory has proved that the reliability of the motor's operation depends on the performance of the brush on a large level.

D88尊龙我們可依據碳刷的消費辦法,分為兩類。一類是有色碳刷,即金屬石墨電刷。一類是黑色碳刷。有色碳刷中,含有色金屬,主要是銅粉、銀粉、其次是鉛粉、錫粉、氧化鉛粉等,余量為鱗片石墨粉。各種金屬粉末含量幾隨碳刷的技術請求而定。

D88尊龙We can divide into two types according to the consumption of carbon brush. One kind is colored carbon brush, that is, metal graphite brush. One type is black carbon brush. Colored brush, including non-ferrous metals, mainly copper, silver, lead, followed by tin powder, lead oxide powder, flake graphite powder for allowance. The content of all kinds of metal powder depends on the technical request of carbon brush.

D88尊龙當金屬含量到達以上時,可不加粘結劑,將粉末混勻后直接壓制成型。否則要參加粘結劑(煤瀝青、煤焦油或樹脂等)。黑色碳刷選用石油焦、瀝青焦、炭黑、木炭以及自然石墨粉等,參加局部粘結劑(如煤瀝青、煤焦油和人造樹脂等)制造的。

When the metal content reaches above, the binder is not added, and the powder is mixed and then formed directly. Otherwise, join the binder (coal tar, coal tar or resin, etc.). Black carbon brushes are made from petroleum coke, pitch coke, carbon black, charcoal and natural graphite powder, etc., and take part in local binder, such as coal tar pitch, coal tar and artificial resin, etc.

高電阻碳刷是采用樹脂粘結劑經固化制造的碳刷,而焙燒后的產品稱炭刷和石墨刷(以自然石墨為主要原料)經石墨化后的產品稱電化石墨刷。

D88尊龙High resistance carbon brush is the resin binder by curing brush manufacturing, and the calcined products called carbon brush and graphite brush (natural graphite as the main raw material) graphitised after product called electrographite brush.
