Embodiment Construction
[0010] According to the embodiment of the present invention, the hydraulic system transmission mechanism executes the sequential action method of the components, and its main steps include:
[0011] ⑴Manually operate the operating mechanism of construction machinery, and at the same time, use manual multi-way reversing valve control, and the sequential action of each actuator of the processing machinery adopts stroke control. When the working parts move to a certain position, an electric signal is sent through the electric stroke switch For the electromagnet, push the solenoid valve to control the continuous action;
[0012] (2) Set a travel valve and connect the corresponding oil circuit, and add a time control unit and a pressure control unit at the same time;
[0013] ⑶ When the pump is running normally, the delay relay sends out an electrical signal to close the unloading valve and establish a normal working pressure. Signal or open the sequence valve to let the pressure ...
