The servo hydraulic press is in the general hydraulic press and the direction control circuit, while the AC servo hydraulic press plus the quantitative oil pump is composed of a controllable hydraulic source, instead of the ordinary induction motor to drive the uncontrollable hydraulic source, combined with various sensors, through the motor control, to achieve the pressure of the energy-saving system, position, speed control. The servo hydraulic press adds displacement sensors to the main cylinder and auxiliary cylinder, and enters the hydraulic pressure sensor in the main cylinder to realize position, speed, pressure, and closed-loop control.
Servo hydraulic presses improve performance and save energy
1. Operational errors of common sense. For example, the three phases are reversed, the fuel tank is not enough, and the pressure regulating valve has no friends to increase the pressure. This usually comes up on newbies in the press.2. Insufficient power supply. It usually appears on the old servo hydraulic press, or the pump is lost, or the motor is aging. You put your palm in the tubing and see if the servo hydraulic press is pressing. If the suction is strong, the pump is fine; motion aging is relatively rare, and real aging is loud because it can't bring so much power.
3. Oil leakage, first of all, there is no obvious sign of oil leakage on the surface of the servo hydraulic press, and there is no damage to the oil seal piston. Next to this first one will be dismantled for oil as there really can't be a solution.
4. The hydraulic valve is disconnected. The valve is blocked, and the internal spring is damaged by impurities and cannot be reset, which may cause the pressure to fail. If it is a manual valve, remove it.
5. It is also possible that the hydraulic gauge is damaged.
The servo hydraulic press increases the proportion of the safety valve at the outlet of the auxiliary cylinder to reach the floating edge of the blank bracket on the pressure side of the auxiliary cylinder. The motor is used for the high-power AC servo hydraulic press, the connection between the motor and the controller, and the flow control is realized by controlling the speed of the motor, and the main oil volume control and voltage regulation are realized. Make full use of high-power AC servo hydraulic press, high efficiency, controllable, adjustable, good reliability and other advantages, realize the optimization of process parameters, thus improve the performance of hydraulic press, reduce energy consumption Hydraulic processing is an important equipment, driven by motor hydraulic pump, production The high-pressure liquid produces linear motion through the hydraulic cylinder. Due to the wide adaptability of servo hydraulic presses, it is widely used in metal and non-metal forming processing. The application of high-power AC servo hydraulic press in hydraulic press replaces ordinary induction motor, which can simplify the structure of hydraulic system, improve performance and save energy.
