摘要： The present disclosure provides a fracturing equipment. The fracturing equipment includes: a plunger pump, a main motor and a noise reduction device. The plunger pump is used for pressurizing liquid. The main motor is connected to the plunger pump by transmission for providing driving force to the plunger pump. The noise reduction device is constructed as a cabin structure and covers outside the main motor and isolates the main motor from the plunger pump. With the fracturing equipment according to the present disclosure, the fracturing equipment is driven by the main motor with relatively low noise during operation. The noise reduction device isolates the main motor from the outside, which can effectively reduce the noise intensity transmitted to the outside during operation, thereby achieve the effect of noise reduction. In addition, the plunger pump is isolated from the main motor by the noise reduction device, thus realizing isolation of high-pressure dangerous areas and ensuring safe operation.
