钻井泵内外置一体式润滑油路系统
摘要：
本实用新型公开了一种钻井泵内外置一体式润滑油路系统，在钻井泵的泵体的内腔中安装有齿轮油泵，该齿轮油泵的一端通过吸油管与吸油过滤器连通，另一端通过进油管三与分油器连通；在钻井泵的泵体外侧分别安装有油泵总成一和油泵总成二，其中油泵总成一的一端与泵腔内的吸油管一连通，油泵总成一的另一端通过进油管一与分油器连通；油泵总成二的一端与泵腔内的吸油管二连通，油泵总成二的另一端通过进油管二与分油器连通；分油器通过多个分流管连通到各个润滑点。本实用新型结构，避免了因供油油压不足造成的泵损坏。
摘要（英）：

The utility model discloses a lubricated oil piping system of external integral type in bore hole pump installs the gear oil pump in the inner chamber of the pump body of bore hole pump, the one end of this gear oil pump is through inhaling oil pipe and inhaling the oil filter intercommunication, and the other end is through advancing oil pipe no. 3 and separator intercommunication, installing oil pump assembly no. 1 and oil pump assembly no. 2 respectively in the pump body of the bore hole pump outside, wherein inhaling an oil pipe intercommunication in one end and the pump chamber of oil pump assembly no. 1, the other end of oil pump assembly no. 1 is through advancing oil pipe no. 1 and separator intercommunication, inhale two intercommunications of oil pipe in the one end of oil pump assembly no. 2 and the pump chamber, the other end of oil pump assembly no. 2 is through advancing oil pipe no. 2 and separator intercommunication, the separator communicates each lubrication points through a plurality of shunt tubess. The utility model discloses the structure has been avoided damaging because of the not enough pump that causes of fuel feeding oil pressure.
