Detailed introduction
Parameters

■The whole machine adopts two or four columns of symmetrical structure with a speed of up to 1500 rpm. Compared with the traditional compressor, the structure is simple, compact, large displacement, more convenient for maintenance, and high-power integrated skid mounting is possible. . The unit has stable operation, small vibration, long service life, excellent material selection and advanced technology. It is an upgraded product of the company's M-type and D-type compressors, and has a wider application range. M-type high-speed energy-saving compressor is especially suitable for large-displacement working conditions or variable frequency working conditions of medium-pressure intake air. The D-type high-speed energy-saving compressor is especially suitable for large-displacement working conditions or variable-frequency working conditions of high-pressure intake air.

Features

■ The fuselage and middle body are made of alloy cast iron, with high strength, strong rigidity and excellent vibration resistance. The self-lubricating performance of the middle part is stronger. The middle part adopts the extended design and the special scraping oil structure, and the scraping performance is obviously improved, thereby reducing the consumption of lubricating oil, reducing the oil content in the natural gas, and reducing the use of the degreasing auxiliary machine such as the separator.

■ The crosshead body is made of ductile iron material with high strength and compact crystal. Its support surface is made of babbitt and has good wear resistance.

■ The motor is directly driven by the diaphragm coupling, easy to install and adaptable. The diaphragm coupling has good compensation ability in the axial, radial and angular directions, which is convenient for maintenance and high reliability.

■ Pre-filmed boron-containing cast iron cylinder liner: Pre-filmed boron-containing cast iron uses centrifugal casting technology to make the crystal grains more dense and uniform. The pre-film treatment of the cylinder mirror surface greatly improves the life of the piston ring, and the wear resistance is greatly improved compared with the conventional material.

■ The friction sealing surface of the piston rod adopts the ceramic matrix composite spraying process to improve the surface hardness and wear resistance; the multi-composite nano-wear layer is sprayed on the end surface of the piston ring groove, which greatly improves the hardness and wear resistance to resist high speed and high The frequency impact and the life and safety of the piston are greatly improved.

■ The packing seal uses a new material, polyetheretherketone, which enhances the matching of the seal to the piston rod and reduces the friction coefficient and frictional heat between the piston rod and the seal.

■ The air valve is a dedicated high-speed air valve with high stability and superior performance.

■ The main oil pump is a gear pump with stable operation and simple design. The end gap is easy to adjust and the efficiency is high. Its own heavy-duty bearing prolongs the service life of the pump.

■ Lubricating oil system is equipped with oil-free flow switch, temperature controller and automatic oil replenishing device to ensure the safety and stability of the lubrication system. The work is intelligent and humanized.

■ The oiler is supplied by the world's leading manufacturers. It is powered by the main motor and equipped with a distributor. The structure is simplified, the volume is small, the space is arranged, the area of ​​the kneading surface is saved, and the maintenance convenience is improved.

■ The speed can be up to 1500 rpm. If the frequency conversion technology is adopted, the speed adjustment range is wider, which is especially suitable for areas with large fluctuations in intake pressure. According to the actual usage of the user, the air volume can be automatically adjusted. When used in the compressor of the mother station, the speed can be automatically adjusted according to the actual situation, so that the compressor is always in the best working condition, and the exhaust volume is obviously improved, which is better than that of the ordinary compressor. obvious advantage.
