Guangzhou Zhongtian Machinery Technology Co., Ltd. Belt Drive Screw Air Compressor Pricing. 1. Easy Maintenance with Belt Drive The air compressor features a belt drive mechanism, allowing for quick machine transformation while meeting various pressure demands of users. The user-friendly automatic tensioning mechanism and the isolation design of moving and stationary parts reduce maintenance workload and ensure a safer operating environment. 2. Unique and Rational Layout Awarded for its rational layout, integrating mechanical and electrical components, the machine requires minimal foundation at the user's site, making transportation and installation extremely convenient. The internal space is divided into cold and hot chambers, which do not interfere with each other. The scientific internal air circulation ensures complete cooling of components, extending the service life. To reduce noise, a fully enclosed, detachable housing is designed with flame-retardant soundproofing foam, offering better flexibility in considering the placement of the air compressor. It not only meets environmental protection requirements but also facilitates machine cleaning. 3. Energy-Efficient Screw Main Unit The main unit is recognized in the industry for its exquisite and unique design and precise manufacturing. Its optimized helix design reflects efficiency and durability, significantly optimizing the rotor meshing line, reducing the leakage triangle area, and further enhancing volumetric efficiency. The use of large diameter and optimal rotor length-to-diameter ratios ensures high displacement with low power consumption. The unique bearing arrangement supports the rotor ends with fixed radial bearings and flexible thrust bearings. The large-scale heavy-duty bearing design greatly extends the service life, ensuring normal operation even under extreme conditions. The lip seal with a slotted inner ring has a pump-like action due to the high precision dimensions and materials, effectively preventing leakage.
