Embodiment Construction

[0037] Such as Figure 1-Figure 7 Shown:

[0038] The present invention provides a quick-installed combined piston rod of a drilling pump, including a piston front rod 26, a connecting mechanism and a tailstock 19 arranged in sequence; wherein,

[0039] The end of the piston front rod 26 away from the tailstock 19 is movably connected with the piston 11;

[0040] The connecting mechanism is movably connected with the piston front rod 26 and the tailstock 19 respectively.

[0041] The quick assembly piston rod of the drilling pump provided by the present invention avoids the practical problem that the clamp, cylinder liner gland and cylinder liner must be disassembled when replacing the piston 11, reduces the working intensity of the personnel replacing the piston 11, and improves the replacement of the piston 11. Operational efficiency, the drilling pump quick assembly piston rod replacement process provided by the invention is simple; the drilling pump quick assembly piston...

Abstract

The invention discloses a quick-installation combined piston rod of a drilling pump, which solves the technical problem in the prior art that the replacement of the piston seriously restricts the on-site use efficiency of the drilling pump. It includes a piston front rod (26), a connecting mechanism and a tailstock (19) arranged in sequence; wherein, the end of the piston front rod (26) away from the tailstock (19) is movably connected to a piston (11); the The connecting mechanism is movably connected with the piston front rod (26) and the tailstock (19) respectively. The present invention avoids the practical problem that the clamp, cylinder liner gland and cylinder liner must be disassembled when replacing the piston (11), reduces the work intensity of the personnel replacing the piston (11), and improves the operating efficiency of the piston (11) replacement. The replacement process of the quick-installed combined piston rod of the drilling pump provided by the invention is simple.

Description

technical field [0001] The invention relates to the field of oil and gas drilling equipment, in particular to a quick-installed combined piston rod of a drilling pump. Background technique [0002] Drilling pump is a very important component of oil and gas drilling equipment. Its function is to provide drilling mud with pressure for the drilling process, so that the drilling mud can carry the bottom cuttings back to the ground and provide continuous mud circulation for continuous drilling. power. The piston rod of the drilling pump is a key part of the drilling pump. Since the piston installed on the piston rod is the most frequently replaced vulnerable part, the replacement of the piston is an important maintenance content for the normal use of the drilling pump. [0003] The traditional drilling pump piston rod is an integral piston rod, that is, it is made of one piece of material, and its installation structure is shown as follows: figure 1 shown. Due to the constrain...
