AI Technical Summary

Technical Problem

Existing internal combustion engine-driven fracturing trucks have relatively low power, while electric-driven fracturing skids, although powerful, are scattered, occupy a large area, and are difficult to move, failing to meet high power requirements and being inconvenient to install and move.

Method used

Design an internal combustion engine-driven fracturing pump unit that integrates the fracturing pump, motor unit, rectifier inverter unit and power supply unit into one unit. It uses an internal combustion engine as the energy source and combines a transfer gearbox and a planetary gear reducer to achieve high power output. The cooling system is set independently on the trailer.

Benefits of technology

It achieves high power output, occupies a small area, is lightweight, and is convenient to relocate and install, reducing the risk of heavy loads, improving the overall efficiency of the equipment and reducing the purchase cost.

Abstract

This utility model discloses an internal combustion engine-driven fracturing pump unit, comprising two integrated internal combustion engine-driven fracturing pump trailers and one integrated cooling trailer. Each fracturing pump trailer includes a trailer chassis, on which, from right to left, are mounted a high-power internal combustion engine, a transfer gearbox, multiple generators, a PWM generator controller cabinet, an inverter controller cabinet, multiple drive motors, a planetary gear reducer, and a fracturing pump. The cooling trailer includes a cooling trailer chassis, on which two cooling systems are arranged front and rear. Each cooling system includes an internal combustion engine cylinder cooling unit, an internal combustion engine intercooling unit, a generator and PWM generator controller cabinet, an inverter controller cabinet, and a drive motor cooling unit. This design integrates the fracturing pump, motor unit, rectifier-inverter unit, and power supply unit of a traditional electric fracturing pump into one unit, achieving high power while also offering advantages such as small footprint, light weight, and convenient relocation and installation.
