Fracturing and acidizing well cementing pumps

The utility model discloses a fracturing and acidizing well cementing pump, chiefly comprises a power end and a fluid end. The utility model is characterized in that a retarding mechanism of the power end is arranged at the external side of the pump case. By adopting a gear pair to reduce the speed, the pump case structure is simplified, the pump volume is reduced, and the fracturing and acidizing well cementing pump is adapted for the arrangement of the vehicle table. The oil ports on the two ends of the bent axle of the power end are provided with filings sucking sleeves. The tiny iron filings in the fluid oil can be removed, and the abrasion of the lubricating component is reduced. A valve body at the fluid end adopts an integral type. A sealing element is sulfurized with the valve body into integration. The weight and the effective force of the motion of the valve body are lightened. The action of the pump valve is flexible, and the service life of the pump valve is further improved. The utility model is especially adapted for the fracturing and acidizing well cementing work of the arrangement of the vehicle table of the oil filed, which can be also used for conveying other liquid.
