Abstract

The invention provides a pump head body design method, a pump head body machining method and a fracturing pump. The pump head body design method comprises the steps: building a pump head body initial model; performing simulation analysis on the operation condition of the pump head body initial model; and according to the simulation analysis result, modifying the pump head body initial model until preset conditions are met, and obtaining a pump head body design model. According to the pump head body design method, all operation working conditions of the pump head body initial model are simulated in simulation software so as to find out the easy-to-crack area of the pump head body initial model, the pump head body initial model is modified according to the simulation analysis result, and finally the pump head body design model is obtained. By means of the mode that design optimization is conducted through simulation analysis, the complicated calculation and analysis workload in the pump head body design process can be reduced; the prestress of the pump head body design model can ensure that the pump head body counteracts or reduces the tensile stress in the pump head body under the high-pressure alternating hydraulic load, ensures that the pump head body is not easy to crack, and prolongs the service life of the pump head body.

Description

technical field [0001] The invention relates to the technical field of oil and gas field fracturing equipment, in particular to a design method and processing method of a pump head body and a fracturing pump. Background technique [0002] At present, fracturing pumps are used in the fracturing process of oil and gas fields, but the pump head body of the fracturing pump will be impacted by high pressure and frequent alternating pressure pulses during extreme work, and it is prone to fatigue tensile stress cracking, which will shorten the working life of the pump head body. Insufficient status quo. [0003] As the core component of fracturing equipment technology, the pump head body has extremely high economic value, but every year, the pump head body of the fracturing pump is scrapped due to tension cracking, which accounts for more than 90% of the scrapped pump head body of the fracturing pump. After analysis, it is found that the tension cracking of the pump head body of t...
