CNG Hydraulic Piston-type Sub-station Compressor

Qingdao Lenado Intelligent Equipment Co., Ltd. is one of the most reliable manufacturers and suppliers of cng hydraulic piston-type sub-station compressor in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk customized cng hydraulic piston-type sub-station compressor from our factory.

The hydraulic piston compressors produced by our company offer advantages over traditional mechanical piston compressors, including lower energy consumption, less noise, a lower failure rate, and reduced maintenance costs.

The hydraulic reciprocating compressors produced by our company have been further optimized and improved; they feature two-stage or multi-stage compression. There are various models available, either with pure air cooling or mixed cooling systems. The overall design of these compressors is rational and simple, making maintenance easy. The compressor control system developed by our company enables real-time monitoring of the equipment's operation, allows automatic control and adjustment of its performance based on operating conditions, triggers alarms in case of abnormalities, and offers functions such as automatic fault diagnosis, emergency shutdown, and remote data management.

Here is the English translation of the technical parameters table:

1. Dual-System Redundant Architecture

The unit features a fully independent dual-compressor configuration, in which each compression system is designed to operate either autonomously or in synchronized parallel mode. This architecture delivers true operational redundancy: during routine servicing, component replacement, or unexpected fault isolation, one system can be safely taken offline while the other continues running at full or partial capacity. This eliminates the need for a complete production shutdown, dramatically improving overall equipment availability and minimizing costly downtime. The switchover between systems is seamless and can be executed without interrupting the gas supply to downstream processes.

2. High-Capacity, Energy-Efficient Performance

Each independent compression system delivers a rated flow capacity of 1600 Nm³/h, providing flexible throughput to match real-world demand profiles. The drive system is powered by two 30 kW motors (2×30 kW), intelligently staged to match load requirements. Compared to conventional single-motor or oversized-drive designs, this distributed-drive approach reduces specific energy consumption by approximately 20%, delivering substantial electricity cost savings over the equipment's service life. The modular power layout also reduces peak inrush current, easing stress on the facility's electrical infrastructure and enabling smoother integration with existing plant power systems.

3. Advanced Pure Air-Cooling System

The compressor employs a 100% air-cooled heat dissipation design, utilizing high-efficiency finned-tube heat exchangers and optimized axial-flow fans to ensure rapid and uniform thermal transfer under all operating conditions. By eliminating the need for a water-cooling circuit, the system removes an entire category of potential failure points - there is no risk of coolant leakage, no water pump maintenance, no scaling or fouling in heat exchanger passages, and no oxidation-related corrosion. This dry-cooling approach significantly reduces the probability of unplanned failures, extends the intervals between major overhauls, and makes the unit exceptionally well-suited for deployment in remote locations, arid regions, or facilities where water supply is limited or costly to maintain.

4. Premium Imported Sealing Technology

All critical sealing elements within the compression chamber - including piston rings, rod packings, valve seals, and static gaskets - are manufactured from high-grade imported materials sourced from globally recognized suppliers. These components are engineered to withstand the demanding pressure cycling, temperature fluctuations, and gas chemistry inherent to natural gas compression. The result is a dramatically extended service life for the entire sealing system, with reduced gas leakage rates, lower fugitive emissions, and fewer scheduled seal replacements. This not only improves long-term reliability and safety but also reduces the total cost of ownership by minimizing both parts consumption and labor hours associated with seal maintenance.
