Introduction

Reliant on the kinetic energy of mud fluid to generate electricity and applicable as an alternative to traditional lithium batteries to power down-hole instruments continuously; with high safety performance, reliability, high energy efficiency and environmental friendliness, it can be added with an energy-storing unit to collect static MWD data when pump operation is paused or terminated. 

• A 300W capacity to ensure over 350 hours of continuous underground operations.
• Utilizes the kinetic energy of mud for power generation, featuring high safety performance, reliability, high energy efficiency and environmental friendliness
• Can be configured with an energy-storing unit to support static data collection.
• Compatible with different interfaces.
• Boasts an ultra-long service life, high reliability and the ease of maintenance.
• With adjustable turbines in size to accommodate different levels of displacement.
• Offer customization services for multiple parameter, up to 4000W.
