Product Description

Product Description

deliver robust, high-pressure performance for low-to-medium flow applications. Built with hardened components (crankcase, cylinders, piston rods) and modular designs, they ensure durability, easy maintenance, and adaptability to variable loads. Key advantages include multi-stage pressure capabilities, oil-free options for contamination-sensitive processes, and compatibility with diverse gases such as nitrogen, CO2, natural gas, hydrogen, and biogas.
Ideal for oil & gas, chemical processing, renewable energy, and industrial systems, these compressors excel in environments requiring reliable gas compression, intermittent operation, or extreme pressure stability. Their mechanical simplicity and scalability suit both fixed and mobile setups.

Key Components of a Compressor
1.Compressor Main Unit
The main unit types of compressors include: diaphragm type, piston type, screw type, and liquid-driven type. The main unit comprises the following components: crankcase, crankshaft, connecting rod, piston, cylinder block, cylinder head, and sealing elements.
2.Piping and Cooling System
Common cooling methods for compressors include water cooling or air cooling. Some piston compressors utilize a hybrid approach with gas air-cooling and partial water cooling for the cylinder head. Cooling systems can be custom-designed and manufactured according to customer requirements.
3.Power Drive
Compressors are predominantly driven by electric motors (over 90% of applications). In scenarios without electrical power, diesel engines or natural gas engines may be employed. Our company offers custom-engineered engine-driven solutions based on customer specifications and machine models.
4.Electrical Control System
The electrical control system is divided into high-voltage and low-voltage sections:
High-voltage section: Refers to power supply systems with voltages of 220V/380V or higher, primarily used for driving high-power equipment such as motors.
Low-voltage section: Includes controllers, instrumentation, and other low-voltage devices, typically operating at safe voltages of 24V or 36V.
5.Oil Pressure System
The lubrication system is critical for stable compressor operation. It not only lubricates moving components and reduces operating temperatures but also ensures discharge pressure stability in diaphragm compressors, where oil pressure directly governs consistent performance.

Chemical Process Compressor Description 
refer to process reciprocating piston compressors used to compress various single or mixed media gases in petroleum and chemical processes, as well as chemical exhaust gas recycling systems. Its main function is to transport the medium gas in the reaction device and provide the required pressure to the reaction device. Features 1. Designed for specific process flow. 2. The whole machine is skid-mounted and advanced in structure. 3. The compressor types are: 4. The middle body of the slideway and the cylinder can be designed in different structural forms according to the process requirements.

Main components
1.Cylinder Assembly: Cylinder block, piston (with rings), and cylinder head (housing intake/discharge valves).
2.Crankshaft Mechanism: Crankshaft, connecting rod, and crosshead (in long-stroke models) to convert rotary motion into reciprocation.
3.Valve System: Intake and discharge valves regulating gas flow.
4.Sealing Components: Piston rings and packing glands to prevent gas leakage.
5.Lubrication System: Oil pump, filter, and cooling systems (water jackets or fins) to manage heat and friction.
6.Drive & Safety: Coupling/pulley for power transmission, relief valves, and pressure/temperature gauges.
7.Features: Modular design for easy maintenance, multi-gas compatibility (N2, CO2, natural gas, H2, biogas), high-pressure capability via multi-stage compression, and rugged construction for durability.

Advantages of piston compressor
1.Wide pressure range, applicable from low pressure to high pressure.
2.Strong adaptability, exhaust can vary over a large range.
3.High thermal efficiency, lower energy consumption and energy saving.
4.Compared with diaphragm compressors, they are smaller, lighter, and cheaper to transport across borders.

CO2 compressor
Product description

1) Carbon dioxide has a high critical temperature and can be liquefied at 31.3°C and 7.14MPa. When used in winter, the interstage cooling temperature cannot be too low;
(2) When carbon dioxide is below 60MPa, it is conducive to gas compression;
(3) Due to the relatively high density of carbon dioxide gas, it is not advisable to use an excessively large average piston speed, otherwise the valve resistance will be large;
(4) Carbon dioxide gas contains a small amount of water and is highly corrosive, so gas valves, coolers and buffer tanks must be made of stainless steel.

The main advantages of the product
1.Through the optimized design of fluid mechanics and the efficient 4-pole motor, the valve plate improves
C.O.P. value;
2.With a wide operating range, the compressor can be safely used in commonly used cascade systems or expansion systems
machine;
3.Safety valves are installed at both high and low pressures;
4.suction and exhaust valves;
5.Low vibration due to good mass balance;
6.low gas pulse;
7.Suitable for frequency conversion;

Structure introduction: The unit consists of compressor host, motor, coupling, flywheel, piping system, cooling system, electrical equipment, and auxiliary equipment.
