D type natural gas compressor

D type compressor is a kind of 2-thread symmetry balanced compressor. 2 cranks are put in 180°. This compressor has good balance quality. Main types of this compressor are listed below.
1.Rated piston force: 20KN stroke: 100mm piston rod diameter: 30mm
2.Rated piston force: 35KN stroke: 100mm piston rod diameter: 45mm
3.Rated piston force: 55KN stroke: 120mm piston rod diameter: 55mm
4.Rated piston force: 80KN stroke: 120mm piston rod diameter: 60mm
5.Rated piston force: 80KN stroke: 240mm piston rod diameter: 60mm
6.Rated piston force: 120 KN stroke: 320mm piston rod diameter: 70mm
7.Rated piston force: 160 KN stroke: 320mm piston rod diameter: 80mm
8.Rated piston force: 220 KN stroke: 280mm piston rod diameter: 85mm
9.Rated piston force: 320 KN stroke: 280mm piston rod diameter: 95mm
10.Rated piston force: 400 KN stroke: 320mm piston rod diameter: 110 mm
    All these compressors are suitable for compressing various media, such as air, oxygen, nitrogen, hydrogen, water gas, coal gas, associated gas, natural gas, carbon dioxide, carbonization gas, hydronetrogen gas, which base on the condition of material clients provided. Choose the suitable data of pressure and special material.
    The main body is the main part of compressor, which casted by gray cast iron with good quality and formed in frame structure. It emphasizes not only on hardness, but also on strength. The adoption of the theory of frame structure and well arranged and chief strings make the compressor convenient in processing, installation as well as maintenance.
    It analyses the stress and deform through the finite element analysis by CAD(Computer—Aided Design) to optimize the structure. Some types of compressors are adopted short crank shaft stroke that reduce the stress of crank shaft and increase the reliance of crank shaft under the same piston—working speed and diameter.
    Cylinder is made in triplet wall structure, not only used to cool the compressing media with water jacket but also prevent high-temperature gas from being conducted to cylinder surface to injury the operator.
    Piston is designed in equal-intensity structure. If needed, melt piston, cast piston and alloy aluminum piston can be chosen to use. Piston rod is made of high-intensity alloy steel or stainless steel and stressing can shape screw thread. Oil free piston ring and support ring are made of durable CFRP.
    The packing is our corporation patent product. The seal ring of packing takes CFRP strengthening plastic. The packing is cooled by water, sealing well, durable.
    The valve is designed separately according to gas elements that the users provided and to using condition, which can lessen the loss of valve.
