Driving mechanism for plunger pumps in oil field installations
Mobile oil field pumping installations of up to 1600 kW power at a pressure up to 140 MPa are widely used in hydraulic fracturing of beds, acid treatment of the near-face zone, cementation of wells, and other flushing and pressure operations. Equipment in these installations, which include high-pressure plunger pumps of high unit capacity, are mounted on mobile bases of limited lifting capacity (KrAZ automobile chassis, T-130 tractors, etc.). Very strict demands are made on the reliability, durability, and mass/size characteristics of the pumps and on all the equipment of the mobile installations. In modern pumps, an axial load of up to 100 tons or more, which is transmitted to the crankshaft, acts on each plunger. The engine of the installation rotates the crankshaft through a multiple-speed transmission and the transmission shaft of the pump. The forces acting on the elements of the driving part of a pump with a connecting rod - crank drive and a single-reduction tooth gear are described.
