When the motor stops running, the hydraulic hydraulic reversing valve of the hydraulic press in the system software enters the inverse ratio position. The inverse ratio effect of the hydraulic hydraulic reversing valve of the hydraulic press in the figure is type O, that is, the closed brake pedal pipe. At this moment, the motor has a rotating development direction because of the torque formula, so the low-speed gear Hydraulic motor manufacturer A momentary high pressure is created at the oil return port of the motor (that is, the pressure is devastating). The pressure of the high pressure oil exceeds the linear pressure of the speed control valve. According to the overflow effect of the speed control valve, the high pressure oil in the oil return port of the oil motor is discharged to the oil inlet of the motor according to the speed control valve.
Because the brake pedal pipe is turned off, the motor oil inlet cannot be filled immediately when the motor is rotating, which will cause suction. The pressure oil from the oil return hole overflows to the motor oil inlet hole, which can alleviate the problem of motor suction and fill the oil inlet hole with motor oil.
Since the oil motor can rotate in two directions Small hydraulic motor The manufacturer has set 2 speed regulating valves for the cache file control circuit. We can watch online videos according to people's columns. Most of the DC transformer control circuits use the basic elements of the DC transformer of the speed regulating valve to produce the DC transformer Hydraulic motor The enterprise governor valve is simple and clear, and its application field is very large. Cache file control circuit of hydraulic cylinder
The basic elements of the cache file of the hydraulic cylinder are the same as those of the oil motor. When the hydraulic reversing valve of the system software hydraulic press regulates the speed, because of the torque formula of the hydraulic cylinder fitness movement, the hydraulic cylinder will have a momentary high pressure inside. According to the cache file valve, this high pressure will be released to maintain the stability of the hydraulic cylinder fitness movement.
