Double - stage compression screw machine: how to work double - stage compression screw machine

At present, in the screw air compressor on the market, there are mainly two kinds of single-stage compression and two-stage compression. Single-stage compression is more familiar to everyone and widely used. In actual use, some air compressors with large power and large gas production demand often use two-stage compression screw machine.

A brief discussion on the selection factors of two-stage compression screw machine

We must first understand the demand for compressed air in the selection of two-stage compression screw machine, including the quality and quantity of air requirements for the end user in the factory. A careful assessment of these requirements and a good understanding of the differences between the two will ensure that our two-stage compression screw system is properly configured.

Double stage compression screw machine: double stage compression screw machine gradually replaced the piston compressor

At present, domestic manufacturers of two-stage compression screw machine through the introduction of technology, technical cooperation or independent research and development, improve the technical content and performance quality of the product, with the improvement of the requirements of the use of environment, energy consumption, environmental protection and other aspects, refrigeration unit energy saving is one of its development trends.

Double - stage compression screw machine: how to prevent double - stage compression screw machine carbon accumulation specific analysis

The reasons for the formation of carbon deposition in the two-stage compression screw machine are more complex, mainly because the oil in the internal lubrication system of the two-stage compression screw machine is often in the form of mist and high temperature, high pressure, high oxygen partial pressure air and metal catalyst contact so that the air compressor oil rapidly oxidizes and deteriorates. On the other hand, the continuous evaporation of air compressor oil makes the oil remaining in the piston top exhaust valve cavity and exhaust pipe continuously heated decomposition, dehydrogenation polymerization. The product is mixed with mechanical impurities in the inhaled gas and metal dust in the compressor, and deposited on the surface of the body is further heated, which becomes carbon accumulation.

Double stage compression screw machine: double stage compression screw machine compared with the advantages of the piston compressor

With the improvement of people's requirements on using environment, energy consumption and environmental protection, energy saving of refrigeration unit is also one of its development trends. At present, the COP value of the domestic series of two-stage compression screw machine has been higher than the piston compressor, and has achieved stepless energy regulation and adjustable content product ratio within the range of 10-100 percent, which is also conducive to energy saving.

How to deal with high temperature fault of two-stage screw compressor

Compared with the piston air compressor, the screw air compressor has more accessories: sensors, temperature control valves, filters, main controllers, etc., which also makes the screw air compressor more complex than the piston air compressor, and the later maintenance is also more important. Of course, in the face of high temperature environment, the operation status of accessories also needs attention. The comps compressor will explain how to deal with the high temperature fault of the two-stage screw compressor.
