​Why should hydraulic presses be equipped with cooling equipment?

The main reason for the cooling equipment of hydraulic presses is to maintain the normal operation of the hydraulic system, extend the life of the equipment, and ensure that the hydraulic press works under efficient and stable conditions.

The following are the main reasons for the cooling equipment of hydraulic presses sorted out by Jianlong Hydraulic Technology, a professional manufacturer of intelligent hydraulic machinery in China, for reference:

1. Prevent hydraulic oil from overheating

Hydraulic presses transmit pressure and power through hydraulic oil, which is easy to heat up under high-pressure working environment. If the temperature of hydraulic oil is too high, it may cause its viscosity to decrease, which in turn affects the working efficiency and control accuracy of the hydraulic system. Cooling equipment can effectively control the oil temperature to ensure that the hydraulic oil always remains within the appropriate temperature range.

2. Maintain the working stability of the hydraulic system

Excessive temperature will cause thermal expansion of seals, pipes and other components in the hydraulic system, which may cause leakage, pipe rupture and other faults. The cooling system can prevent these problems, ensure the stable operation of the hydraulic system, and prevent equipment damage caused by high temperature.

3. Extend the service life of hydraulic oil

Hydraulic oil will accelerate oxidation in a high temperature environment, produce acidic substances and sludge, which will affect the lubrication performance and transmission efficiency of the hydraulic oil. The cooling system reduces the oil temperature, slows down the aging of hydraulic oil, prolongs its service life, reduces the need for frequent replacement of hydraulic oil, and reduces maintenance costs.

4. Protecting the components of hydraulic presses

Many key components in hydraulic presses, such as pumps, valves, cylinders, etc., will be aggravated and shortened in high temperature environment. The cooling system can provide these components with a suitable operating temperature, reduce wear and failure, and extend the overall service life of the equipment.

5. Improve work efficiency

When the hydraulic oil runs at a suitable temperature, it can maintain a better viscosity to ensure the efficiency and response speed of the hydraulic transmission. If the temperature is too high, the efficiency of the hydraulic system will decrease, resulting in slower equipment operation or insufficient power output. Through the adjustment of the cooling equipment, the hydraulic system can always operate in the best working state, thereby improving production efficiency.

6. Prevent safety hazards

Excessive hydraulic oil temperature may also bring safety hazards. For example, overheated hydraulic oil may cause the oil to spontaneously ignite or fire risk. The application of cooling system can reduce these hidden dangers and ensure the safety of operators and production equipment.

7. Meet the requirements of long-term and high-load work

In some high-load and long-term continuous operation occasions, such as large-tonnage stamping or pressing, the hydraulic system is subjected to greater pressure and temperature changes. The cooling equipment ensures that the hydraulic press can operate stably for a long time under high load and prevent shutdown or failure due to excessive temperature.

The core purpose of the cooling equipment for the hydraulic press is to keep the temperature of the hydraulic system within an appropriate range, ensure the stable and efficient operation of the hydraulic system, extend the service life of the equipment and hydraulic oil, reduce the occurrence of failures, and improve safety and work efficiency. Therefore, the cooling equipment is an indispensable part of the hydraulic system, especially in high-load or continuous operation environments.
