New Product Ideas Long Service Life Low Maintenance Hydraulically Driven Compressor for Tunnel Construction

High Efficiency & Displacement: 30%-50% higher displacement than traditional models under same power, reducing equipment count and land occupation.

Easy Maintenance Design: Modular structure with no crankshaft or belt. Core seal replacement takes only 4 steps and about 45 minutes.

High-Pressure Stability: Pressure upper limit reaches 210MPa. Stable compression with small vibration and low noise for ultra-high pressure needs.

Oil-Gas Isolation & Purity: Multi-level sealing ensures complete physical isolation between hydraulic oil and gas, eliminating oil pollution.

Long Service Life: Low piston frequency (6-10 times/min) increases MTBF by 40%. Continuous operation life exceeds 25,000 hours.

Compact Integration: Floor area reduced by about 50% compared to traditional models, suitable for limited spaces and mobile stations.

Stable Start-Stop Operation: Supports frequent start-stop under pressure without unloading, adapting to large load fluctuations like hydrogen stations.

Hydraulic Drive Principle: Uses high-pressure hydraulic oil to drive pistons directly, abandoning complex mechanical transmissions for high purity.
