Industrial Vacuum Oil Treatment Machine

The vacuum oil purifier is designed based on the different boiling points of water and oil, consisting of vacuum heating tank, filter, condenser, primary filter, water tank, vacuum pump, oil discharge pump and electrical cabinet. The vacuum pump creates a vacuum to draw oil into the primary filter for removing large particles, then into the heating tank. Heated to 40~75°C, the oil is atomized to evaporate water into vapor, which is cooled and discharged by the condenser. Finally, the oil is filtered to remove particulate impurities, achieving dehydration, degassing and purification.

Product Features

The vacuum system (vacuum tank, vacuum pump, condenser, liquid storage tank, air supplement system) adopts optimized structure to increase oil surface area and stroke for full water/gas overflow, with advanced foam elimination system to prevent oil injection. The three-stage filtration system uses gradient pore size glass fiber media to protect the oil pump and extend filter life, ensuring stable filtration accuracy and high oil cleanliness. The heating system adopts step-by-step gradual heating (thermal surface load <1.0W/cm²) to avoid oil deterioration, with 0~100°C adjustable oil temperature and dry-burn protection. The automatic control system uses PLC with multiple safety protections (overload, overvoltage, phase sequence, abnormal shutdown), and the integrated bridge structure with detachable oil tank is available in mobile, fixed and vehicle-mounted types.

Working Principle

Contaminated oil enters the primary filter to remove large particles, then flows into the vacuum heating tank and is heated to 40~75°C. The atomized oil evaporates water into vapor, which is sucked into the condenser by the vacuum pump, cooled and discharged. The dehydrated oil is then pumped into the fine filter to remove particulate impurities, and the clean oil is discharged from the outlet. The automatic control system monitors vacuum degree, temperature and liquid level to ensure stable and safe operation.

Advantages

It is equipped with a special gear pump driven by motor, featuring low noise, strong self-priming ability and stable operation. The oil suction port coarse filter protects the oil pump and prolongs the service life of the main filter. Thermal relay protection prevents motor damage caused by overload. The fine filter can be selected with different precisions to meet various filtration requirements. It has optimized vacuum system with advanced foam elimination technology, ensuring no oil injection during operation. The step-by-step heating system avoids oil deterioration and has dry-burn protection. The PLC automatic control system ensures safe and reliable operation. The integrated structure reduces volume and the detachable oil tank avoids ground oil pollution.

Application

Filtration of new oil and filling new oil after filtration. Purification of in-service oil in hydraulic lubrication systems. Bypass filtration during the operation of hydraulic lubrication systems. Efficient removal of impurities, water and gas from various industrial oils to improve oil insulation performance and purity.
