In cold environments — such as northern winters or low-temperature workshops — the viscosity of lubricating oil increases, reducing its fluidity. The built-in heating function preheats the oil to an optimal temperature, ensuring smooth and uniform grease injection into bearings. This prevents uneven distribution or blockages caused by thickened oil in low temperatures.
2. Precision Quantitative Oil Injection
The oil injection process is controlled via a pressure pump or screw propulsion system, enabling accurate dosage. This effectively avoids:
Over-injection, which can cause grease overflow, and
Under-injection, which may lead to insufficient lubrication. Precision control ensures optimal lubrication with minimal waste.
