摘要： 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.

摘要： The present invention discloses a reduction gearbox for turbine fracturing with a compact overall structure, a small volume, a light weight and a large transmission ratio, wherein the power is input through a small end gear of the sun wheel axle, slowdown and increased the torque through the engagement between the big end gear of the sun wheel axle and the planetary gear, and output through the planetary carrier. A structure of the planetary gear set with reduced gear size and number is more suitable for the reduction requirement of a turbine engine. It can be observed through an observation hole by opening the cover plate, which is convenient for maintenance. A brake apparatus works with a brake pad so as to promptly stop the equipment in case of emergency to ensure the equipment and personal safety.
