The PYRH series intelligent fuel injection lubrication system is powered by compressed air, combined with pneumatic components, pneumatic high-pressure lubrication pumps, or electric high-pressure lubrication pumps. Through the control system, the oil or grease is atomized to form a dry oil mist, which is sprayed onto the gear surface in a timed and quantitative manner through the pipeline. A tough oil film is formed on the gear surface, which circulates periodically to improve lubrication effect, reduce equipment wear, and minimize oil loss. The control system adopts a microcomputer controller to set system parameters and monitor the operation of the system; The flow sensor detects in real-time whether the oil and gas flow is normal. The entire device has a high degree of automation, easy operation, simple maintenance, and avoids equipment damage caused by poor lubrication.
