CDZ Nitrogen Booster Charging Vehicle

I. Product Introduction

The nitrogen booster charging vehicle is a hydraulic-driven high-pressure nitrogen specialized charging equipment, specifically developed for high-pressure gas of industrial bladder accumulators. The whole unit is modularly assembled with a mobile chassis, suitable for multi-point mobile charging operations in factory areas. The unit consists of four major modules: hydraulic station, nitrogen booster system, control system, and mobile cart. The nitrogen booster system is the core component, directly controlling hydraulic output pressure and determining the nitrogen pressurization upper limit. The equipment relies on the hydraulic pressurization principle and can be paired with specialized charging tools to boost low-pressure nitrogen to the 10-65MPa pressure range for output.

Industry pain point addressed: Conventional industrial gas cylinder output pressure is generally below 12MPa, while working condition energy storage accumulators typically require pressure of 12MPa or above. Ordinary gas cylinders cannot directly complete high-pressure nitrogen charging for accumulators. This hydraulic nitrogen booster charging vehicle can pressurize to compensate for the pressure difference, solving the industry challenge of insufficient conventional gas cylinder pressure for high-pressure accumulator nitrogen charging, suitable for routine nitrogen charging maintenance of high-pressure energy storage accumulators.
