Title:
PLUNGER PUMP SYSTEM, PRESSURE PULSATION COMPENSATION METHOD THEREFOR, AND FRACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/070742
Kind Code:
A1
Abstract:
A plunger pump system, a pressure pulsation compensation method therefor, and a fracturing device. The plunger pump system comprises a first plunger pump (100) and a fluid pressure compensation structure (200). The fluid pressure compensation structure (200) is configured to compensate pressure pulsation of a fluid outputted by an output end (101) of the first plunger pump (100). The fluid pressure compensation structure (200) comprises at least one linear motor (210) and a second plunger pump (220) driven by the at least one linear motor (210), and an output end (221) of the second plunger pump (220) is communicated with the output end (101) of the first plunger pump (100). The fluid pressure compensation structure having the linear motor and the second plunger pump is added to the plunger pump system provided in the embodiments of the present application. The linear motor has a small volume, and can be conveniently integrated with the second plunger pump to achieve a compact design, and the linear motor can be conveniently adjusted and controlled to compensate the pressure pulsation of the fluid outputted by the first plunger pump.
