Description

Technical Field

[0001] The utility model relates to the technical field of fracturing pumps, in particular to a fracturing pump box body used for petroleum mining. Background Art

[0002] In the process of oil extraction, the fracturing pump is one of the main equipment to increase oil production. The fracturing pump is divided into a power end and a hydraulic end. The hydraulic end of the fracturing pump is provided with structures such as a pump head body and a suction cover. Due to the influence of the working environment, the pump head body and the suction cover of the hydraulic end are exposed to the outside for a long time; the existing fracturing pump casing cannot protect the pump head body. A large amount of mud and sand and gravel impurities will be generated at the oil extraction work site. The hexagonal groove arranged on the outside of the suction cover will be blocked by impurities, and the connection between the suction cover and the pump head body is usually a threaded connection. The environment of the oil extraction site is relatively harsh, which will corrode the connection and cause the suction cover and the pump head body to stick together, hindering the maintenance of the pump head body.

[0003] According to the Chinese patent application number 202322101953.4, a fracturing pump casing for oil production is isolated and protected by protective glue on the outside of the hexagonal groove during use. However, the entire device is used in a harsh oil production environment. The protective glue alone is easily damaged, and the poor sealing performance still makes it easy for impurities to invade the groove. Therefore, an improved fracturing pump casing for oil production is needed to address this problem. Utility Model Content
