Abstract
The utility model discloses a kind of EMU main air compressor oiling tool, to overcome the oil port position and the narrow space when the oiling of prior art's main air compressor of EMU cannot be adapted to the deficiency. The tool includes oil pipe, oiling electric pump, output connector, flow display device and oil storage cabin. The oiling electric pump inlet is connected with the oil storage cabin through the oil pipe, and the outlet is connected with the output connector through the oil pipe. The output connector can be connected with the oil port of the main air compressor. The control switch is connected with the motor on the oiling electric pump. The flow display device is installed at the outlet of the oiling electric pump. The tool uses the oil pipe to extend and cope with the problem of high oil port position. It is stable and reduces space occupation. It is suitable for narrow environment. Point control and flow display improve operation convenience and accuracy. It effectively overcomes the deficiencies of prior art.
