  servo electronic pressWhat are the advantages?

Servo electronic press (referred to as servo electronic press, servo electronic press) is an energy-saving hydraulic press that uses a servo motor to drive the main drive oil pump, reduce the control valve loop, and control the slider of the hydraulic press. It is suitable for stamping, die forging, press fitting, Straightening and other processes, let's talk about the advantages of servo electronic presses.

1. Energy saving:

Compared with ordinary hydraulic press,servo electronic pressThe overall control of the system does not contain proportional servo valves or proportional pumps. The servo electronic press has the advantages of energy saving, low noise, low temperature rise, good flexibility, high efficiency, and convenient maintenance. It can replace most of the existing ordinary Hydraulic press has broad market prospects. According to different processing technologies and production rhythms, servo-driven hydraulic press can save 30% ~ 70% of electricity compared with traditional hydraulic presses.

2. Low noise:

Servo hydraulic oil pumps generally use internal gear pumps or high-performance vane pumps, while 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, when driving the servo electronic press for pressing and returning, the motor runs at rated speed, and its emission noise is 5dB ~ 10dB lower than that of traditional hydraulic presses. When the slider drops rapidly and the slider is stationary, the speed of the servo motor is 0. So the servo-driven hydraulic press basically has no noise emission. In the pressure holding stage, the noise of the servo-driven hydraulic press is generally less than 70dB due to the low speed of the motor, while the noise of the traditional hydraulic press is 83 dB ~ 90 dB.

3. High degree of automation, good flexibility and high precision;

  servo electronic pressThe pressure, speed, position closed-loop digital control, high degree of automation, good precision, in addition, its pressure and speed can be programmed to meet the needs of various processes, it can also achieve remote automatic control.

4. Less heat, cost reduction:

Since the hydraulic system of the servo-driven hydraulic press has no overflow heating and no flow when the slider is stationary, there is no hydraulic resistance heating, and the calorific value of the hydraulic system is generally 10% ~ 30% of that of the traditional hydraulic press. Due to the low calorific value of the system, most servo-driven hydraulic presses can be equipped with hydraulic oil cooling system, and some hydraulic presses with higher calorific value can be equipped with low-power cooling system, because the pump has the characteristics of zero speed and low heat most of the time, the oil tank of the servo-controlled hydraulic press can be smaller than that of the traditional hydraulic press, and the oil change time can be extended, so the hydraulic oil consumed by the servo-driven hydraulic press is only 50% of that of the traditional hydraulic press.

5. Easy to maintain:

Due to the cancellation of the proportional servo hydraulic valve, speed control circuit and pressure regulating circuit in the hydraulic system, the hydraulic system is greatly simplified, and the cleanliness requirement of hydraulic oil is far less than that of the hydraulic proportional servo system, which reduces the impact of hydraulic oil pollution on the system.
