Product Description

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.
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.

Chemical Process Compressor Description 
Chemical process compressors 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: Z type, D type, M type. 4. The middle body of the slideway and the cylinder can be designed in different structural forms according to the process requirements.
