Detailed Description
An auxiliary device for enhancing the lubricating capability of a mud pump of a drilling machine is shown in fig. 1. Mainly comprises an external oil supply device 6, a connecting pipeline 5, a first one-way flow valve 21, a second one-way flow valve 22 and a filter 4. The auxiliary device is connected with a built-in oil supply pump system, and the purpose of effectively improving the lubricating capacity through cooperative work is achieved.
The external oil supply system 6 is fixed at the outer end of the slurry pump shell and consists of a motor and a hydraulic pump. The output end of the external oil supply system 6 is connected with the inlet of a first one-way circulation valve 21 by penetrating into the shell of the slurry pump through a connecting pipeline 5, the outlet of the first one-way circulation valve 21 is connected with one side of the connecting pipeline 5 of the three-way connector, and one port of the other two connecting ports of the three-way connector is connected with a connector base 8 and is used for conveying to a structure needing lubrication; the other port is connected to the inlet of a second one-way flow valve 22, and the outlet is connected to an internal oil supply system 3 which is arranged in the original slurry pump and is used for providing the circulation of lubricating oil through a connecting pipeline 5. The two one-way circulation valves enable the internal oil supply system device and the external oil supply system device to form a fixed circulation direction according to the connection rule, and can avoid conflict between the internal oil supply system and the external oil supply system in cooperative work.
