270-360 m³/min Centrifugal Compressor Widely-used in Pharmaceutical Industry
Description
Centrifugal compressor has a wide range of applications, mainly due to its 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.
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.
Advantages of GooDSeaA centrifugal compressor
Item | Features of GooDSeaA | Other Vendors |
Integrated unit design | Simple overall layout, compact structure, reasonable and simple installation, only the air pipe, water pipe and electrical system need to be connected. Bring benefits to customers, small amount of investment, save a lot of installation time and costs | Fix the unit with four corner gasket (no shock absorption function and potential safety hazard exists) |
The main structure adopts horizontal split type | The gearbox, bearing and sealing system are all of horizontal split structure, which is convenient for maintenance. During maintenance, it is not necessary to dismantle all the air inlet and exhaust pipes, volute, etc. Compared with vertical sectioning, it can save more than 6 times of maintenance time. | Some companies adopt vertical segmentation structure |
Inlet regulating guide vane | Equipped with imported regulating guide vane, it can save 9% energy upon the maximum inlet flow than butterfly valve. Wide adjustment range. Save a lot of operating costs. | Butterfly valve, low cost, but high energy consumption |
Efficient backward curved impeller and integral milling diffuser | Efficient three-way flow backward curved impeller designed by aviation university team is adopted to make the compressor reach 60-105% of flow regulation range. The diffuser made of aviation aluminum material ensures no leakage and minimal internal friction. Compared with cast iron and cast aluminum, it has corrosion resistance, high strength and small air resistance. The efficiency of the compressor is further improved. Save a lot of operating costs | Some companies adopt casting diffuser |
Tilting bearing | With the advanced five piece tilting pad bearing, it can automatically adjust to achieve the best stable operation state, excellent buffer performance, good anti oil film oscillation performance, and can automatically adjust the service life of more than 100000 hours. The design service life of the unit shall not be less than 30 years. | |
Cooling system | GooDSeaA cooler structure adopts water flowing inside the pipe and gas flowing outside the pipe , with guide rail and roller. The drawable straight tube cooler is made of Navy copper, which has excellent corrosion resistance and is not easy to scale. | Some companies use stainless steel. Poor heat conduction efficiency, low cost, easy to oxidize and scale. It is not suitable for cleaning and maintenance. |
Oil circuit system | Free switching parallel double oil filter effectively avoids the disadvantage that the single oil filter must be shut down to replace the filter element and extends its service life. | Single oil filter is used in some companies, so it is impossible to change the filter element without stopping the machine under emergency |
Carbon ring sealing system without oil | Two relatively independent working systems, air circuit and oil circuit, ensure the air quality of compressor, and overcome the leakage problem of compressor through reliable labyrinth seal or carbon ring seal system. | |
Simple Control System | Standard PLC + color LCD touch screen, with large storage function, multiple monitoring and protection functions, can display multiple information at the same time in the same picture, which is easier to operate and more stable. | Some companies use microcomputer controller, LED display single page scrolling display screen, display content is too less, operation is troublesome. |
Anti surge function | The system consists of surge pressure sensor and motor current sensor. When the change ratio of the last stage exhaust pressure and the change ratio of the motor current is higher than the set value of surge, PLC will regard this situation as surge, and then alarming system will work and compressor will stop meanwhile discharging the air. Through the advanced method of continuously monitoring the changes of the two parameters of system pressure and current at the same time, it can avoid the misoperation of surge only by single signal judgment, and effectively prevent the occurrence of surge | |
Vibration protection function | Goodsea centrifugal compressor is equipped with vibration measurement system in each stage of compression section, which has protection measures for each stage. And the equipment has the functions of numerical display, alarm, shutdown, etc. Ensure safe and stable operation of the whole set machine. | In order to reduce the cost, only one vibration measuring point is arranged on each shaft. The monitoring cannot be guaranteed and the accuracy is not high. |
Commissioning & Testing
High Speed Dynamic Balance Test
Gradually balancing from low speed to high speed.
The equilibrium speed is as close as possible to the critical speed.
Balance at rated working speed to ensure balance accuracy.
Rotor Test
The wheel rotation fracture test is carried out without damage in the ground with 122% maximum rotational speed.
Working on the engine at 115% maximum allowable steady-state operating speed for 5 minutes without cracking and the size is within the allowable range.
On the engine, exceed the maximum allowable average steady-state temperature of 42℃, work for 5 minutes without cracking, and the size is within the allowable range.
Vibration Test
20% margin between critical speed and maximum working speed.
During the test of the components and the whole machine, there is no adverse reaction to the vibration in the working speed range.
Performance, Characteristic Test
Performance tests under design conditions.
Characteristic tests under non-design conditions.
Process the test data to determine whether the performance of the component is up to standard and draw a characteristic curve.
