The stroke control of the Honggang Hydraulic Cutting Machine includes two aspects: upper limit position adjustment and lower limit position control. There are several ways to adjust the upper limit of the working mechanism.
1. Change the position of the travel switch and adjust it by mechanical-electric-hydraulic interlock control.
2, time control: This control method is to delay the input signal after a certain time delay output, so as to control the suction time of the solenoid valve to achieve the working stroke control, there is a direct use of the control button to input the trigger signal, but also through the hydraulic circuit The change in pressure is input to the trigger signal by the pressure sensing element.
There are two methods for controlling the lower limit position of the working mechanism of the Honggang Hydraulic Cutting Machine.
1. Stroke switch control: By changing the position of the travel switch, it is controlled by mechanical-electric-hydraulic interlocking mode, and the signal of the lower limit position of the stroke is given by the travel day switch with contact or the non-contact switch.
2, time control: This control method is to delay the input signal after a certain time delay output, so as to control the suction time of the solenoid valve to achieve the working stroke control, there is a direct use of the control button to input the trigger signal, but also through the hydraulic circuit The change in pressure is input to the trigger signal by the pressure sensing element.
