Maximum discharge pressure: 35MPaG

 

Technical characteristics

1、 The engine is designed and manufactured in accordance with DEMA standards, and the compressor is designed and manufactured in accordance with APl618 and ISO13631..

2、 With natural gas as fuel, nonpressurized, skid-mounted as a whole, heavy duty with low speed, applicable to severe environment, and can realizing unattended operation on the site;

3、 Good fuel adaptability; the engine can normally operate with a low heating value within 16510kJ/Nm³~47700 kJ /Nm³; no detonation or power drop;

4、 The rotating speed and torque are wide enough to operate under 60-100% of rated conditions, which benefits the adjustment of minimum displacement capacity that can be as low as 36% of design displacement;

5、 Multiple adjusting modes of rotating speed, clearance mechanism, single-acting & double-acting cylinder allow adjusting displacement, load, temperature and other working parameters properly, thus adapting to the change in operating conditions within a relatively large range.

6、 Engine and compressor share one frame and one crankshaft, subject to symmetrically balanced arrangement, so that inertia force and inertia moment can be well balanced and vibration is small;

7、 Internal mixing gas injection and loop scavenging can effectively cool and clean cylinders, thereby ensuring that fuel can be controlled and saved;

8、 Isolated room of compressed air between compressor frame and engine piston can effectively prevent combustion exhaust from releasing to oil sump, prevent pollutions by lubricating oil and extend the service life;

9、 Power cylinder has a simple structure, without such wearing parts as rocker arm, tappet rod, cam, timing mechanism etc, and with less quick-wear parts and maintenance works;

10、 The special sulfur resistant design and manufacturing technology can make the compressor operate safely and reliably in a gas field with a high sulfur content;

11、 Local, remote and network data acquisition and monitoring system etc. has a high level of automation and completion, and can operate reliably.

 

Application

The compressor unit can be used for gas gathering and transportation, oil & gas treatment and processing, gas lit, as well as light hydrocarbon recovery. Working medium: natural gas, coal-bed gas and shale gas.

 

 

SPLIT COMPRESSOR UNIT

Split Compressor Unit

Technical Parameters

Range of power: 10~7,500kW

Air displacement: 0.1~1000x10⁴Nm³/d

Maximum discharge pressure: 52MPaG

 

Technical Characteristics

1、Designed and manufactured as per APl618 and lS013631.;

2、 Horizontally and symmetrically balanced structure, with an accurate weight difference in reciprocating parts in each row, can effectively balance the inertia force and inertia moment, so that the compressor unit can operate with a small vibration and a low noise;

3、 Highly stiff bare compressor mechanism optimized via mechanical treatment can eliminate wall surface vertical to force direction, so that the bearing capacity can be increased;

4、 Bearing surface of transmission pat is subject to a low specific pressure value design, so that working surface of moving part will have a low temperature rise, a small thermal expansion and a good directivity;

5、 Wide gas path and natural cooling cylinder will reduce the gas flow loss and improve the efficiency of compressor;

6、 The gas valve with a special structure and a targeted design features a high efficiency, a wide range of adaptive operating conditions and a long service life;

7、 The special sulfur resistant design and manufacturing technology can make the compressor operate safely and reliably in a gas field with a high sulfur content;

8、 Compressor unit is complete with multiple kinds of power sources including gas engine, electric motor, diesel engine etc, to meet a variety of requirements;

9、 Multiple kinds of skid-mounted structures (fixed, mobile, vehicle-mounted etc.) can adapt to a variety of field environments; Designed and manufactured as per APl618 and lS013631;

10、 Local, remote and network data acquisition and monitoring system etc. has a high level of automation and completion, and can operate reliably.
