The present invention discloses a five cylinder plunger pump with an integral power end structure. In the power end assembly of the five cylinder plunger pump, the crankcase and the crosshead case adopt an integral welding structure, so that the power end assembly has a higher structural strength and a better support stability to reduce vibration of the whole pump. The cylinder spacing is 13-14 inches, increasing the bearing area of the connecting rod, the crosshead and the bearing bushes, and ensuring the high power output of the five cylinder plunger pump. The high power five cylinder plunger pump can effectively solve the problems of narrow area in shale gas fracturing wellsite and the need for multiple fracturing equipment, thus reducing the use of equipment and facilitating the arrangement of the wellsite. The long stroke design of 11 inches is beneficial to realize the operation requirement of large displacement and enhance the operation efficiency. The multi-point support design of the crankcase, the crosshead case and the hydraulic end assembly can enhance the support strength of the five cylinder plunger pump and reduce the vibration, thus better ensuring high load operation and more smoothly running.

The present invention discloses a multi-point supported five cylinder plunger pump, including a power end assembly, a hydraulic end assembly and a reduction gearbox assembly, the power end assembly includes a crankcase, a crosshead case and a spacer frame, the crankcase, the crosshead case and the spacer frame are connected in sequence, the hydraulic end assembly is fixed on the spacer frame, the reduction gearbox assembly is fixed on the crankcase, a crankshaft support is disposed at the bottom of the crankcase, and the crankshaft support is used to support the crankcase, a crosshead support is disposed at the bottom of the crosshead case, and the crosshead support is used to support the crosshead case, a hydraulic support is disposed at the bottom of the spacer frame, and the hydraulic support is used to support the hydraulic end assembly. Beneficial effects: the multi-point support design of the crankcase, the crosshead case and the hydraulic end assembly can enhance the support strength of the plunger pump and reduce the vibration, thus better ensuring high load operation and more smoothly running.
