Description

Technical Field

[0001] The utility model relates to a high-bar pump, in particular to a high-bar pump for transporting mud. Background Art

[0002] In drilling construction, the circulation process of mud is from the mud pool through the mud pump to the drill pipe, then from the drill pipe to the bottom of the hole, and then from the bottom of the hole to the high-bar pump to the desander to the mud pool. In this process, the conduction and transportation of the high-bar pump plays a vital role. Due to the influence of the construction stratum, the gravel cover layer is thick and there are many calcium junction layers. The mud returned from the hole mouth carries a large amount of gravel particles and coarse sand. At this time, the high-bar pump not only needs to transport the mud to the mud pool, but also needs to filter the first gravel particles and coarse sand. During operation, the gravel particles and coarse sand pass through the volute, bearings, oil seals and other components, which are easy to cause component damage, thereby reducing service life and work efficiency.
