Product Features

Adaptive two-stage compression process: Within the intake pressure range of 3-20MPa, no switching of compression stages is required. It automatically adapts to normal two-stage compression operation, eliminating the impact of drastic gas flow fluctuations during stage switching, ensuring smooth operation. Under the same motor power, the average gas flow increases by 30%-50%, while under the same average gas flow, motor power can be reduced by25%-30%;

Adapts to different filling needs: The unit features direct filling and programmable filling functions;

Multifunctional soundproof enclosure: Equipped with sound insulation, noise reduction, rainproofing, heating, and insulation functions. It includes maintenance space and lifting devices, explosion-proof lighting, ventilation, gas leakage alarms, and an escapable safety door to ensure equipment and personnel safety;

Fully automated pneumatic instrumentation: Instrument air for fully automated pneumatic actuators can use compressed air or natural gas based on user requirements, with corresponding safety measures implemented;

Easy maintenance and low operating costs: Each cylinder column, piston structure, and valve structure of the reciprocating compressor are identical in size, reducing the variety of wear-prone parts and lowering maintenance and operating costs. It features a wide intake pressure range, high gas flow, high automation, and energy efficiency.

Product Advantages

Excellent operational balance performance: Two-row horizontal symmetric balanced unit with crankshaft angles offset by 180°, ensuring balanced inertial forces and even piston force distribution;

Superior overall rigidity: The integrated body is designed using finite element analysis software to simulate compressor motion loads, and the body and intermediate block can adopt a one-piece structure;

Lubricating oil level gauge: Can be equipped with clamp-type thermal resistors and electric heaters to monitor oil temperature and level, and can interlock with unit operation;

Convenient inspection and maintenance: The body is equipped with windows for disassembly, assembly, and inspection of crossheads;

Pre-lubrication oil pump: Enforces pre-lubrication of moving parts, ensuring reliable operation;

Wide range of applications: The D-type machine can adapt to the needs of satellite stations, mother stations, and standard stations based on different models.
