Advantages and functions of hydraulic presses

energy saving

Compared with ordinary hydraulic presses, hydraulic presses do not contain proportional valves or proportional pumps in the overall control of the system. Service-driven hydraulic presses have the advantages of energy saving, low noise, low temperature rise, good flexibility, high efficiency, and easy maintenance. They can replace most of the existing ones. Ordinary hydraulic press has broad market prospects. Compared with the traditional hydraulic press, the energy saving effect is remarkable. According to the different processing technology and production rhythm, the driving hydraulic press can save 30% to 70% of electricity compared with the traditional hydraulic press.

low noise

Internal gear pumps or high-performance vane pumps are generally used to drive hydraulic oil pumps. Traditional hydraulic presses generally use axial piston pumps. Under the same flow and pressure, the noise of internal gear pumps or vane pumps is 5dB lower than that of axial piston pumps. 10dB. The motor runs at the rated speed when the hydraulic press is pressed and returned, and its emission noise is 5dB to 10dB lower than that of the traditional hydraulic press. When the sliding block is falling rapidly and the sliding block is stationary, the motor speed is 0, so the driving hydraulic press has basically no noise emission. In the pressure holding stage, due to the low speed of the motor, the noise of the hydraulic press is generally less than 70dB, while the noise of the traditional hydraulic press is 83dB to 90dB. After testing and calculation, under normal working conditions, the noise generated by 10 hydraulic presses is lower than that generated by a common hydraulic press with the same specifications.

less fever

Since the hydraulic system of the driving hydraulic press has no overflow and heating, and there is no flow when the slider is stationary, there is no hydraulic resistance to generate heat. The heating value of the hydraulic system is generally 10% to 30% of that of the traditional hydraulic press. Due to the low calorific value of the system, most of the driving hydraulic presses may not be equipped with a hydraulic oil cooling system, and some of the larger calorific value can be equipped with a low-power cooling system. Due to the characteristics of zero speed and low heat generation of the pump most of the time, the oil tank for controlling the hydraulic press can be smaller than the traditional hydraulic oil tank, and the oil change time can be extended, so the hydraulic oil consumed by the driving hydraulic press is generally only about 50% of the traditional hydraulic press.

high degree of automation

The pressure, speed and position of the driving hydraulic press are fully closed-loop digital control, with a high degree of automation and good precision. In addition, its pressure and speed are programmable to meet various technological needs, and remote automatic control can also be realized.

efficient

Through appropriate acceleration and deceleration control and energy optimization, the speed of the hydraulic press can be greatly increased, and the working cycle is several times higher than that of the traditional hydraulic press, which can reach 10/min to 15/min.

Easy maintenance

Since the proportional hydraulic valve, speed regulating circuit and pressure regulating circuit in the hydraulic system are cancelled, the hydraulic system is greatly simplified. The cleanliness requirements for hydraulic oil are far less than that of hydraulic proportional systems, which reduces the impact of hydraulic oil pollution on the system.
