How does servo hydraulic press improve performance and save energy

The servo hydraulic press is in the general hydraulic press and direction control loop, and the AC servo hydraulic press plus 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, position, speed control of the energy-saving system. The servo hydraulic press increases the displacement sensor in the master cylinder and auxiliary cylinder, and enters the oil pressure sensor in the master cylinder to realize the position, speed, pressure and closed-loop control.

Servo hydraulic presses improve performance and save energy

(1) Common sense operation error. For example, three phase inversion, the tank oil is not enough, and the pressure regulator does not increase the pressure of the friend. This is usually in the new hands of the press.

(2) Insufficient power supply. It usually appears on the old servo hydraulic press, or the pump loss, or the aging of the motor. You put your hand in the oil pipe, see if the servo hydraulic press press if the suction is very large, the pump is no problem; Exercise aging this is relatively rare, real aging is very loud, because it does not bring so much strength.

(3) Oil leakage, first of all, look at the surface of the servo hydraulic press, there is no obvious sign of oil leakage, there is no damage to the words of the oil seal piston. Next to this first one, because really can't find a solution will be dismantled for oil.

(4) The hydraulic valve is disconnected. The valve is blocked, the internal spring is damaged by impurities and cannot be reset, which may lead to pressure failure, if it is a manual valve, remove it.

(5) The hydraulic gauge is damaged, it is also possible.

The servo hydraulic press increases the proportion of the relief valve at the auxiliary cylinder outlet to reach the floating edge of the blank support on the pressure side of the auxiliary cylinder. The motor is used for the connection of high-power AC servo hydraulic press, motor and controller, and realizes flow control, main oil control and voltage regulation by controlling the speed of the motor. Make full use of high-power AC servo hydraulic press, high efficiency, controllable, adjustable, good reliability and other advantages, to achieve the optimization of process parameters, so as to improve the performance of hydraulic press, reduce energy consumption Hydraulic processing is an important equipment, driven by the motor hydraulic pump, the production of high-pressure liquid, through the hydraulic cylinder to produce linear motion work. Due to the wide adaptability of servo hydraulic press, it is widely used in metal and non-metal forming processing. The application of high-power AC servo hydraulic press in hydraulic press instead of ordinary induction motor can simplify the structure of hydraulic system, improve performance and save energy.
