Using an Oil Press Press: 6 Tips for Maximum Yield

In modern manufacturing, oil press press is a key production equipment, and its production efficiency directly affects the enterprise's production capacity and economic benefits. How to maximize the output of oil compressors without increasing equipment has become a focus of attention for many production enterprises. This article will systematically introduce six practical techniques to help you comprehensively optimize the working efficiency of oil press presses and achieve a qualitative leap in production capacity.

1. Optimize hydraulic flow: fundamentally improve motion speed

The core operating principle of oil press press lies in the flow control of hydraulic oil - the movement speed of the hydraulic head is directly determined by the hydraulic oil flow rate delivered to the cylinder per unit time (usually measured in gallons per minute or liters of GPM/LPM). The most direct way to increase speed is to increase the flow rate of hydraulic oil.
1. Adjust pump displacement: Variable displacement pumps allow you to adjust displacement settings according to actual needs. By increasing the displacement of the oil pump, the working speed of the oil press press can be directly improved. It should be noted that the capacity of the pump is the ultimate limiting factor for the speed of the compressor.
2. Upgrade pump capacity: If your oil press press is still using an old or mismatched hydraulic pump, upgrading to a higher flow rate (GPM/LPM) pump is the fundamental solution. In the renovation example of a 7000 ton oil press press, technicians increased the pressurized flow rate by 50% and the extrusion speed by nearly doubling by adding a main pump system.

3. Core tip: Flow adjustment needs to be considered together with system pressure. According to the fundamental law of hydraulics - power=pressure x flow rate, increasing the flow rate may reduce the maximum available pressure (compression force) while keeping the motor power constant. Therefore, it is essential to confirm that your processing power requirements are met before making adjustments.

2. Shorten travel time: Cleverly optimize the work cycle

Improving the output of oil press presses is not just about pursuing faster pressing speeds. In fact, the most significant time savings usually come from optimizing the non working parts of the loop - the time close to work and return.
1. Adopting a fast feed circuit: Many modern oil press presses are equipped with fast feed/return circuits. This system utilizes smaller auxiliary cylinders or regeneration circuits to quickly move the pressure head during non working stages, and once it approaches the workpiece, it switches to the main cylinder for compression. This design cleverly balances the demands of speed and force.
2. Analyze the cycle stage: Carefully study the working cycle of your oil press press and record the time of the main cylinder's idle actions such as lifting, lowering, returning, and ejecting. Even a few seconds of savings can significantly increase daily output when accumulated.

3. Practical points: Through the cycle analysis of the 7000 ton oil press press, technicians found that the idle actions of the main cylinder, such as lifting, lowering, returning, and electrode ejection, account for a high proportion of the total cycle time. Optimizing these links has brought significant time savings.

3. Improve heat management: ensure continuous and stable production

During high-speed operation of the oil press press, the hydraulic oil generates a large amount of heat due to friction. If the cooling capacity of the system is insufficient, it can cause hydraulic oil to overheat, leading to liquid degradation, damage to seals, and potentially causing premature component failure and costly downtime.
1. Monitor oil temperature: Regularly check the hydraulic oil temperature to ensure it is within the normal operating range. Abnormal increase in oil temperature is often a precursor to system problems.
2. Ensure cooling efficiency: Regularly clean the heat exchanger to ensure smooth flow of cooling water. For old oil press presses, upgrading the cooling system may be a necessary investment to ensure high-speed operation.
3. Keep the oil clean: Regularly replace the hydraulic oil and clean the system to prevent pollutants from accelerating component wear and oil quality deterioration. Clean oil can more effectively transmit power and dissipate heat.

4. Key understanding: Heat is the invisible killer of high-speed oil press presses, and effective heat management is the prerequisite for maintaining equipment in an optimized state for continuous operation.

4. Implement intelligent control: precise control of operating parameters

Most modern oil press presses are equipped with advanced control systems, and by setting these intelligent controls reasonably, the production efficiency of the equipment can be significantly improved.
1. Adjust the control valve settings: Modern oil press presses use proportional valves, which can provide precise and variable control over flow rate. By adjusting the settings of these valves, faster movement can be allowed in specific parts of the cycle.
2. Utilize Variable Frequency Drive (VFD): If your oil press press is equipped with a motor with a VFD, you can directly increase its output through the control panel and control the starting frequency of the motor to reduce the impact on the power grid.
3. Multi pump combination control: For large oil press presses, a multi pump combination control system can be used. Through MATLAB simulation analysis, determine the optimization time for starting the oil pump in a time-sharing manner, so that the output flow rate is approximately sinusoidal, which can ensure flow supply and effectively reduce the impact on the compressor.

4. Operation suggestion: Before making any control parameter modifications, please be sure to consult the technical manual of the equipment to understand the safe adjustment range.

5. Reduce no-load energy consumption: eliminate energy waste

Hydraulic presses often have idle time such as waiting, loading and unloading during production. During this period, the motor is still running at full speed, consuming a large amount of electrical energy. By optimizing the energy consumption during these time periods, production costs can be reduced.
1. Set automatic shutdown: For longer production intervals, the system can be set to automatically stop the hydraulic main motor after detecting no operation for a certain period of time (such as 5 minutes). When it is necessary to resume work, simply press the original start button, and the machine will automatically wake up without affecting the original workflow.
2. Evaluate Applicability: The applicability of this method needs to be evaluated based on the production process and the start-up characteristics of the equipment. For example, there is a case where the hydraulic main motor is set to automatically stop when there is no action, achieving multiple benefits such as saving electricity, extending equipment life, and reducing CO2 emissions.

3. Precautions: It is necessary to confirm that your oil press press motor is allowed to start and stop frequently, and the energy consumption during the starting process will not offset the saved energy.

6. Refined maintenance: preventive measures ensure efficient operation

Maintaining the oil press press in optimal condition requires a systematic maintenance strategy, rather than passive fault repair.
1. Regular inspection of seals: The wear of oil cylinder seals not only causes pressure drop and speed reduction, but also leads to internal leakage, further increasing heat generation.
2. Keep the filter clean: A clogged filter will restrict the flow of hydraulic oil, increase the load on the pump, and reduce system efficiency. Regularly replace the filter according to the manufacturer's recommendations.
3. Comprehensive system inspection: Establish a regular inspection system, including checking the performance of the pump, the response of the valve, the smoothness of the oil cylinder movement, etc., to timely discover and solve small problems, and avoid them from developing into serious faults that cause shutdown.

4. Maintenance value: Preventive maintenance not only reduces unexpected downtime, but also ensures that the oil compressor always operates at its design efficiency, thereby maintaining high output.

Improving the output of oil press presses is a systematic project that requires comprehensive consideration of flow optimization, cycle time reduction, heat management, intelligent control, energy consumption reduction, and maintenance. The most important thing is that any improvement in speed must be based on ensuring safety and long-term stability of the equipment.

The oil press press with faster movement speed has greater kinetic energy and shortens the operator's reaction time. Any speed modification must be accompanied by a comprehensive safety review, which must verify that protective devices, light curtains, and emergency stop circuits remain effective at new and higher speeds. We must never sacrifice safety for the sake of production speed.
By scientifically analyzing and implementing the above six techniques, you can not only significantly increase the output of oil press presses, but also achieve a more energy-efficient, stable, and sustainable production environment, winning key advantages for enterprises in fierce market competition
