AI Technical Summary

Technical Problem

Existing plunger pumps have a slow pumping speed and cannot operate for long periods of time, which makes it impossible to achieve large-flow liquid delivery.

Method used

Design a high-flow-rate plunger water pump, which uses multiple plunger assemblies and a motor assembly. The motor drives the multiple plunger assemblies to reciprocate, and combined with a multi-stage pressurization assembly, it can achieve efficient extraction and discharge of liquid.

Benefits of technology

It enables high-flow-rate liquid transportation, improves the efficiency and sealing of the water pump, and avoids maintenance difficulties caused by excessive size and weight of the device.
