Double-side-arranged incomplete gear transmission type single-cylinder double-cavity slurry pump

Abstract

The invention discloses a double-side-arranged incomplete gear transmission type single-cylinder double-cavity slurry pump. The slurry pump is provided with a power end assembly and a fluid end assembly. The power end assembly is provided with a first transmission shaft and a second transmission shaft, the first transmission shaft is sleeved with a first incomplete gear, the second transmission shaft is sleeved with a second incomplete gear, and a rack penetrates through the first transmission shaft and the second transmission shaft in the vertical direction; the first incomplete gear or the second incomplete gear is meshed with the rack; the axial displacement of the rack provides power for the fluid end assembly. The design thought provided by the invention is more obvious in effect in application of the large-displacement slurry pump, and the large-displacement slurry pump researched and developed by adopting the technology is small in size, light in weight and convenient for field application in application of large-diameter super-long drilling construction of coal, geology, petroleum and the like, complex stratum drilling construction and the like. And the single-cylinder double-cavity working mode greatly prolongs the service life of the slurry pump and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a double-sided incomplete gear transmission type single-cylinder double-chamber mud pump. Background technique [0002] The mud pump is an important equipment for drilling engineering. During the normal positive circulation drilling process, the mud pump will flush the medium (water, mud, polymer flushing fluid, etc.) The through hole in the center of the column is conveyed to the bottom end of the drill bit to achieve the purpose of cooling the drill bit, carrying cuttings, driving the bottom hole drilling tool, etc. Its performance level and service life directly affect the drilling efficiency and construction cost. [0003] In recent years, in the field of oil drilling and production, with the vigorous development of the country's exploration and development of deep-surface and deep-sea oil and gas resources, the drilling and mining depth has gradually increased, an...
