Product Description

Industrial CNG Compressor Natural Gas Methane Oilfield Piston BOG Compressor
Xuzhou Huayan Gas Equipment Co.,Ltd, exporting , piston compressor, , gas cylinder and nitrogen generators with good quality and low price.

Piston compressor is a kind of piston reciprocating motion to make gas pressurization and gas delivery compressor mainly consists of working chamber, transmission parts, body and auxiliary parts. The working chamber is directly used to compress the gas, the piston is driven by the piston rod in the cylinder for reciprocating motion, the volume of the working chamber on both sides of the piston changes in turn, the volume decreases on one side of the gas due to the pressure increase through the valve discharge, the volume increases on one side due to the reduction of air pressure through the valve to absorb the gas.
Main components
1.  Motion system: crankshaft, piston connecting rod assembly, coupling, etc.
2.  Air distribution system: valve plate, valve spring, etc.
3. Sealing system: piston ring, oil seal, gasket, packing, etc.

4. Body system: crankcase, cylinder block, cylinder liner, cover plate, etc.
5. Lubrication system: lubricating oil pump, oil filter, pressure regulating valve, etc.;
6. Safety and energy regulation systems: safety valves, energy regulation devices, etc.

Working principle of piston compressor
When the crankshaft of the piston compressor rotates, the piston will reciprocate through the transmission of the connecting rod, and the working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will periodically change. When the piston of a piston compressor starts to move from the cylinder head, the working volume in the cylinder gradually increases. At this time, the gas flows along the intake pipe and pushes the intake valve to enter the cylinder until the working volume reaches the maximum. , The intake valve is closed; when the piston of the piston compressor moves in the reverse direction, the working volume in the cylinder is reduced, and the gas pressure is increased. When the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve opens and the gas is discharged from the cylinder , Until the piston moves to the limit position, the exhaust valve is closed. When the piston of the piston compressor moves in the reverse direction again, the above process repeats. In short, the crankshaft of a piston compressor rotates once, the piston reciprocates once, and the process of air intake, compression, and exhaust is realized in the cylinder, which completes a work cycle.

Advantages of piston compressor
1. The applicable pressure range of the piston compressor is wide, and the required pressure can be reached regardless of the flow rate;
2. The piston compressor has high thermal efficiency and low unit power consumption;
3. Strong adaptability, that is, a wide exhaust range, and is not affected by the pressure level, and can adapt to a wider pressure range and cooling capacity requirements;
4. Piston compressors have low requirements for materials, and use common steel materials, which is easier to process and lower in cost;
5. The piston compressor is relatively mature in technology, and has accumulated rich experience in production and use;
6. The device system of the piston compressor is relatively simple.
