In the field of subway tunnel construction, refractory shotcrete machine for subway tunnels<\/a> is a key equipment, which plays a vital role in ensuring the integrity and durability of tunnel structure.<\/p>\n

One of the advantages of the refractory shotcrete machine for subway tunnels produced by our company is that it integrates advanced technology to automatically clean the blockage of the conveying line. By combining PLC (programmable logic controller), VFD (variable frequency driver) and air pressure sensor, we developed a system that can detect and clear obstacles in real time. This ensures the smooth and continuous flow of fire-resistant shotcrete materials, minimizes downtime and improves efficiency.<\/p>\n

In addition, we also improved the rotor structure of the refractory shotcrete machine for subway tunnels<\/a> to improve its working performance. By replacing the traditional circular holes with fan-shaped holes, we have increased the volume of the rotor, enabling it to handle larger volumes of materials. In addition, this design change reduces the friction area, thus reducing the rotor speed required to maintain the same output. This not only prolongs the service life of the rubber sealing plate, but also helps to keep the power consumption of the motor low and reduce the operating cost.<\/p>\n

Another innovation we introduced is to combine the spray gun with high-pressure water to facilitate movement. This enables the refractory shotcrete machine for subway tunnels to be positioned and manipulated with higher accuracy and flexibility, so that it can adapt to various tunnel configuration and construction challenges.<\/p>\n

In order to further improve the durability of the refractory shotcrete machine for subway tunnels, we installed an automatic lubricator on the rubber sealing plate. This can ensure the continuous lubrication of worn parts, reduce friction and wear, and thus prolong their service life. This also helps to keep the motor power consumption low, because the refractory shotcrete machine runs more smoothly and has higher efficiency.<\/p>\n
