The 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.

Note: In the unloading process, the compressor pressurizes the gas from the storage tank and then presses it into the tank car through the gas-phase pipeline, and presses the liquid from the tank car to the storage tank through the gas-phase differential pressure to complete the unloading process. When the gas phase is pressurized, the temperature of the gas phase will rise. At this time, forced cooling is not necessary, because if the gas phase is compressed and then cooled, it is easy to liquefy, and it is difficult to establish the pressure difference of the gas phase, which is not conducive to the replacement of the gas phase and the liquid phase. In short, it will cause the prolongation of the unloading process. If it is necessary to recover the residual gas, the cooler can be selected to forcibly cool the gas phase during the recovery operation, so as to recover the residual gas as soon as possible.The loading process is opposite to the unloading process.

Natural gas compressor

As an important modern energy, natural gas is widely used in various fields. For different gas sources, the application methods are different.

Casing gas recovery compressor

Casing gas is a kind of natural gas in oil production wells. If the pressure is high, it will affect the oil production. Originally, it is directly vented. First, it pollutes the environment. Second, it is a waste of energy. So now, the use of compressor pressurization recovery is not only conducive to oil production, environmental protection, but also a good measure to maximize economic benefits. The main components of the gas are methane, ethane, carbon three, carbon four and other gases, and there will be hydrogen sulfide and water mixed in them, the components are relatively miscellaneous. Before entering the compressor, it needs to be purified to remove the acrobatics and liquid free water. Then according to the different needs of users to increase to different levels of pressure.

1. The pressure needs to be increased to about 15-20kg through the direct recovery of the oil pipeline, which depends on the pressure of the oil pipeline.

2. Press it to about 45kg, and use medium pressure tank car for transportation.

3. Press to 250kg and transport by high-pressure tank car.

The latter two methods are suitable for the use of gathering and transmission stations. Most single wells have small gas volume and are relatively scattered, which is not conducive to the rapid loading and transportation of tank cars.

Casing gas recovery compressor is also suitable for oil field associated gas, wellhead gas and other similar conditions.

Pipeline natural gas pressurization

During the use of pipeline natural gas, due to the distance, pipe diameter, elbow and other factors of the pipeline, a certain amount of pipe damage is caused, which is easy to cause insufficient pressure during the use of gas. At this time, it is necessary to use supercharging equipment to increase the pressure of natural gas to meet the use requirements.

This series of compressor unit is mainly used in pipeline natural gas booster transportation, oil and gas treatment plant and other occasions.  Product features
1. Reliable operation and easy maintenance.  
2. Flexible load regulation, wide range of air intake, wide range of application.  
3. Overall skid mounted structure, low noise, easy to install in urban area, saving investment.  
4. Siemens PLC control system, high degree of automation, remote control convenient.
