What Factors Affect the Service Life and Stability of an Oil Press Machine?

Many oil mill owners have this dilemma: whether it's a screw oil press or hydraulic oil press, soon after purchasing the equipment, they experience a drop in oil yield, increased noise, severe screw wear, and even frequent failures. In fact, this isn't just a quality issue with the equipment itself, but is caused by a combination of multiple factors.

1. Equipment manufacturing quality determines basic lifespan

Material selection : It is recommended that core components such as the pressing chamber, screw, and bearings be made of high-strength alloy steel, which should undergo heat treatment and surface quenching to improve wear resistance and fatigue resistance.

Design structure : Reasonable structural design can reduce stress concentration and delay fatigue damage, which is especially important for continuously operating screw oil presses.

Processing precision : High-precision manufacturing can reduce friction and vibration, ensuring a smooth pressing process of the hydraulic oil press.

💡Case comparison: A customer purchased a screw made of ordinary steel and frequently replaced it within a year; while another customer chose a wear-resistant alloy screw, which maintained a good oil yield after three years of use.

2. Operating conditions affect wear rate

Raw material impurity control : Sand, gravel, and metal chips entering the equipment will accelerate the wear of the screw and the pressing chamber. It is recommended to use cleaning equipment before pressing.

Moisture content adjustment : Too high moisture content will reduce the oil yield and may also cause rust and scaling in the press chamber.

Load management : Avoid long-term full-load or overload operation to prevent motor overheating and transmission system damage.

3. Daily maintenance and care are the key to extending life

Lubrication management : Add or replace lubricating grease regularly to prevent dry grinding of bearings and gears.

Tightening inspection : Regularly check whether the bolts and couplings are loose to avoid increased vibration of the equipment.

Replacement of wearing parts : Replace the screw, pressing bar, sealing ring, etc. in time according to the frequency of use.

Equipment cleaning : Clean the residue in the pressing chamber after daily shutdown to avoid blockage and corrosion.

4. The operator's level determines the effect of use

Professional training : Different oilseeds (soybeans, sunflower seeds, rapeseed, cotton seeds, etc.) require different pressing parameters. Familiarity with the process can reduce equipment pressure shock.

Fault identification : Promptly detect abnormal noise, vibration or temperature rise to avoid equipment running with problems.

5. The impact of the use environment cannot be ignored

Temperature and humidity control : Keep the environment dry to prevent rust and degradation of lubricant performance.

Power supply stability : Voltage fluctuations may damage motors and electronic control systems.

Installation foundation : A solid foundation can reduce vibration and maintain equipment stability.

Practical suggestions for extending the life of oil press

Choose a high-quality oil press : give priority to screw or hydraulic oil presses with good reputation, high-quality materials and reasonable structure.

Establish maintenance files : record operating hours, maintenance dates and parts replacement to facilitate tracking of equipment status.

Establish maintenance cycles : lubricate, inspect, and replace wearing parts regularly according to manufacturer's recommendations.

Arrange production reasonably : avoid long-term full-load operation and arrange cooling intervals appropriately.

Technology upgrade : Upgrade screw, filtration system and other components as needed to improve oil output efficiency and durability.

Therefore, the life and stability of the oil press are not determined by a single factor, but the comprehensive result of "equipment quality + correct use + daily maintenance + operating level + environmental conditions".
