470-890 m³ / min Turbine Air Compressor for LNG Industry

Features of Centrifugal Compressors

Centrifugal compressors are now being widely used in many fields, such as Chemical and Petrochemical, Midstream, Fertilizer, Power Generation, Industrial Gases, Textile Industry, LNG industry, this is mainly because it has below advantages compared with piston compressors:
1. The centrifugal compressor has a large gas volume, simple and compact structure, light weight, small unit size and small floor space.
2. the operation is balanced, the operation is reliable, the operation rate is high, and the friction parts are few, because the spare parts need less usage, the maintenance cost and the personnel are small.
3. In the chemical process, the centrifugal compressor can achieve an absolutely oil-free compression process for chemical media.
4. The centrifugal compressor is a kind of rotary motion machine, which is suitable for direct dragging of industrial steam turbines or gas turbines.For general large-scale chemical plants, it is often used as a by-product steam-driven industrial steam turbine to provide power for comprehensive utilization of thermal energy.

Centrifugal Compressor Introduction

A centrifugal compressor is a vane rotary compressor (ie, a turbo compressor). In a centrifugal compressor, a high-speed rotating impeller imparts a centrifugal force to the gas, and a diffusing action of the gas is applied in the diffuser passage to increase the gas pressure.In the early days, this type of compressor was only suitable for low, medium pressure, and large flow, and was not noticed.

Recently, however, due to the development of the chemical industry, the establishment of various large-scale chemical plants and refineries, centrifugal compressors have become a key machine for compressing and transporting various gases in chemical production, and occupy an extremely important position.With the achievements of gas dynamics research, the efficiency of centrifugal compressors has been continuously improved.

Due to the high pressure sealing, the processing of small flow narrow impellers, and the development of key technologies such as multi-oil wedge bearings, the centrifugal compressor has been solved to high pressure and width.

A series of problems in the development of the flow range have greatly expanded the application range of the centrifugal compressor, so that the reciprocating compressor can be replaced in many occasions, and the application range is greatly expanded.

The pressure of industrial high-pressure centrifugal compressors is (150~350)×105Pa, and the pressure of centrifugal compressors for gas injection in offshore oil fields is as high as 700×105Pa.The centrifugal blower used for blast furnace blasting has a flow rate as large as 7000 m3/min, and the power is large at 52,900 KW, and the rotational speed is generally above 10,000 r/min.

Some chemical basic raw materials, such as propylene, ethylene, butadiene, benzene, etc., can be processed into important chemical products such as plastics, fibers and rubber.In the petrochemical plant that produces this basic raw material, centrifugal compressors also play an important role and are one of the key equipment.

In addition, in other industries such as petroleum refining and refrigeration, centrifugal compressors are also extremely critical equipment.

Background

Under the current environmental protection and energy consumption bearing limits all over the world, the importance of energy conservation, consumption reduction and emission reduction has become increasingly prominent, and the largest "main battlefield" is the impeller machinery in the field of energy and power.

Impeller machinery is often one of the most critical and important components in various energy and power industries. The turbomachinery is widely used, including centrifugal compressors, fans, pumps, steam turbines, wind turbines, turbines, turbines, rotors, turbines, propellers. and many more.95% of China's power source is generated from turbomachinery, such as turbines, steam turbines, wind turbines, etc. In the field of energy and power consumption, the most important conversion methods are motors, pumps, etc. 78% of China's power is consumed by turbomachinery.

The energy efficiency ratio of the mechanical power of the national impeller is still far from the international advanced level. The main reason is the two "pain points":

First, the power efficiency ratio is not satisfactory.Impeller machinery involves many disciplines such as mechanics, materials science, and structural science. Due to talents, tools, experience, equipment, etc., the gap between our national impeller mechanisms and international advanced standards is still large.

Second, the quality reliability is not ideal.The impeller machinery uses a continuously rotating blade as the body to convert energy between the fluid working medium and the shaft power, which requires extremely high reliability.There are still many room for improvement in reliability design and production processing, which affect the reliability of impeller mechanical quality......

Thus, GooDSeaA Aerospace Technology (Shanghai) Co., Ltd. was born.

GooDSeaA works together with Top-Level Universities in China, specializing in the field of civil impellers and rotor type line machinery, to create products that can meet “aviation power” and “military quality”, like centrifugal compressors, centrifugal fans, centrifugal vacuum pumps, high-speed submersible sewage pumps, screw compressors, water-lubricated oil-free compressors, oil-free screw vacuum pumps and other products.
