Shield Machine Dedicated Screw Air Compressor
TBM application screw compressor
Because the shield tunneling machine (referred to as the shield machine) is equipped with a special air compressor, its working conditions have the characteristics of high tunnel temperature, high humidity, dust, vibration and other harsh tunneling features, and the machine size is required very small. The maintenance operation space is limited, so the operation and maintenance need to be convenient, and the equipment construction has extremely high requirements for gas source stability and cyclability. For the general factory screw air compressor can not fully meet the special requirements of the above working conditions, so the air compressors used in this industry need to be specially designed for the unique requirements; this series of products can be widely used in subway, tunnel construction, Municipal construction, road mining and other industries.

Application
1. The shield-type air compressor has a compact structure, and the whole system structure is very user-friendly. All maintenance is very convenient and is not affected by the space limitation of the shield machine;
2. The unique horizontal oil and gas separation tank not only ensures the reliability of mechanical separation, but also has the function of the screw mainframe support seat, and utilizes limited space reasonably and effectively;
3. Fine separation adopts spin-on oil separator, which has small volume, easy dis-assembly and assembly, and large processing capacity, ensuring gas content of gas after separation is ≤3PPM;
4. Brazed plate type stainless steel heat exchanger adopts high temperature resistance and long service life; it has the characteristics of small volume, high heat exchange efficiency and corrosion resistance; the PH value of cooling water can be used in a wider range, and can adapt to most of China's current The water quality of the area; due to the split structure of the oil cooler and the post-cooling, the installation and maintenance are convenient, the maintenance cost is low, and the space can be utilized more flexibly;
5. The combined valve body is used to reduce the pipeline connection, which reduces the aging of the pipeline and the oil leakage at the joint connection;
6. The unique automatic adjustment of the belt-free belt ensures the belt is evenly loaded for a long time and effectively guarantees the service life of the belt.
7. Powerful control system with main motor and fan overload, phase imbalance, phase sequence error, exhaust temperature and high pressure protection; with RS-485 communication protocol, can achieve up to 16 air compressor network control, and Support local and remote control functions.
