Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling equipment, in particular to a fracturing pump head structure that saves blank materials. Background Art

[0002] At present, in the field of oil and shale gas extraction, fracturing technology can effectively increase the extraction of oil and shale gas. The fracturing pump is a key equipment in the fracturing extraction process. The performance, quality and reliability of the fracturing pump directly affect the quality and progress of the fracturing implementation process. Among them, the fracturing pump head body is an important structure of the fracturing pump. During the processing of the fracturing pump head body, a position for the threaded boss is usually reserved on the pump head body to ensure subsequent machining procedures. This processing method not only increases the processing cost and processing waste of blank forging and machining, but also increases the workers' processing procedures and processing volume.

[0003] Therefore, it is necessary to propose a technology to improve the above defects. Utility Model Content

[0004] In view of the above-mentioned deficiencies and defects of the pump head body of the prior art fracturing pump, in order to achieve the above-mentioned purpose, the utility model provides a fracturing pump head body structure that saves blank materials, including:

[0005] The pump head body and the power end, the front end of the pump head body is provided with a threaded ring, the threaded ring and the pump head body are detachably connected, the interior of the pump head body is also provided with a through hole, the through holes are provided in multiple groups, and are arranged through the interior of the pump head body, and a pull rod is installed inside the through hole.

[0006] As a preferred technical solution, a slot is provided on the side of the threaded collar close to the pump head body, a slot is provided inside the pump head body close to the threaded collar, and fixing pins are installed in the slot on the pump head body and the slot on the threaded collar.

[0007] As a preferred technical solution, it further includes an end plate, which is arranged between the power end and the pump head body. A positioning hole is provided on the surface of the end plate, and the threaded collar is connected to the power end through the hole.

[0008] As described above, the present invention provides a fracturing pump head structure that saves blank materials, which has the following beneficial effects:

[0009] The utility model provides a detachable threaded collar on one side of the pump head, and a fixing pin for constraining installation is provided between the threaded collar and the head, so there is no need to leave a threaded boss on the original forging basis. The combined structure reduces the volume of the casting blank, reduces the volume and cost of the blank, effectively reduces the processing cost and processing waste of the blank forging and machining, and also reduces the workers' processing procedures and processing amount, thereby effectively improving the economic benefits.
