Problems solved by technology

[0002] The piston is an important part of the drilling mud pump. The mud pump provides power for drilling wells. During the use of the mud pump, it will output the mud back up to realize the function of draining and cooling the drill bit; the current mud pump has a fixed amount of mud. Change, can not be converted and adjusted, the scope of application is small, different use occasions need to prepare mud pumps with different discharge volumes, resulting in waste of equipment, which needs further improvement

Abstract

The invention relates to a slurry pump piston. The slurry pump piston comprises a piston, a conversion block, a sealing strip and a connecting assembly, wherein the connecting assembly comprises a connecting shaft, a blocking ring and a sleeve. According to the slurry pump piston, a connecting point of the piston and a piston connecting rod can be regulated, so that an initial motion position of the piston is converted, and finally, the effect of regulating slurry discharge amount is finally achieved, and the adjustable function of slurry discharge amount of the slurry pump is realized. The slurry pump piston is simple to operate, is convenient to form, is wide in scope of application, is strong in universality and saves equipment procurement expenditure.

Description

Technical field [0001] The invention relates to a mud pump piston. Background technique [0002] The piston is an important part of the drilling mud pump. The mud pump provides the power to clean the well. During the use of the mud pump, the mud will be output and returned to achieve the function of discharging and cooling the bit; the current mud pump has a fixed displacement Change, unable to carry out conversion adjustment, the scope of application is small, different use occasions need to prepare mud pumps with different discharge volumes, resulting in equipment waste, which needs to be further improved. Summary of the invention [0003] In view of the above-mentioned current state of the prior art, the technical problem to be solved by the present invention is to provide a method that can change the starting position of the piston movement, thereby achieving the effect of adjusting the discharge volume and realizing the adjustment of the discharge volume of the mud pump. Fun...
