The BW-250 mud pump is a horizontal three-cylinder reciprocating single-acting piston, which is one of the main supporting equipment for geological exploration. Its main function is to supply flushing liquid (mud or clear water) into the borehole during core drilling to circulate in the borehole to achieve carrying debris back to the ground, cooling and lubricating the drill bit and drilling tool, and protecting the hole wall. Collapse, can also be used as a cement slurry infusion pump in the foundation treatment project. The water-cement ratio of the cement slurry can be up to 1:1. It has the characteristics of small size, compact structure, easy installation and disassembly, and easy handling.
The pump can be used as a 1000-meter large-diameter drilling rig with four displacements. The flushing fluid used should not contain chemical impurities that corrode metals and rubber parts. The recommended specific gravity when using mud is 1.03-1.10, the viscosity is 18-25 seconds, the sand content is not more than 4%, and the pH is 7-8. There must be no mud, weeds, leaves, etc. in the mud to block the debris of the water filter. The length of the suction pipe should not exceed 5-6 meters.
BW-250 type mud pump is mainly used for conveying flushing liquid into the borehole during geological core drilling, and can also be used for soft foundation grouting, mine sewage and liquid transportation;
With four different flow rates and pressures, it can replace cylinder liners of different diameters, with large flow adjustment range and reasonable parameter design. It can be matched with XY-4 and XY-5 vertical shaft core drilling rigs;
The wearing parts such as piston and tie rod seal have long service life and reliable performance;
Compact structure, good detachability, easy to repair and relocate.
