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 ...

Abstract

The invention discloses a method of sequential acting of execution assemblies of a hydraulic system transmission mechanism. An operation mechanism of an engineering machinery is manually operated, and is controlled by a manual multiway reversing valve, and the sequential acting of each execution mechanism of a processing machinery is controlled by travels. When a working part moves to certain position, an electric signal sent by an electrical travel switch is transmitted to an electromagnet, and the electromagnet is pushed to control the continuous action. A travel valve is arranged and is connected with a corresponding hydraulic circuit, and meanwhile, a time control unit and a pressure control unit are additionally arranged. After a pump normally runs, a delay relay sends an electrical signal to close an unloading valve, and a normal work pressure is established. When one execution element completes the preset action, the pressure in a circuit reaches certain value, and the hydraulic fluid passes through in a way of sending an electrical signal by a pressure relay or opening a sequence valve, so as to start the next action. The method has the beneficial effects that the running precision of the machine is favorably improved, the abrasion is reduced, the service life is prolonged, the force on the machine body is assisted, and the like.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to a sequential action method of an executive component of a transmission mechanism of a hydraulic system. Background technique [0002] The hydraulic system has the advantages of large power, good adjustability of working pressure and flow, and heat can be brought back to the oil tank. The hydraulic system device can generate more power than other devices. Under the same power, the hydraulic device is small in size, Light weight, high power density, and compact structure; at the same time, the hydraulic device works relatively smoothly. Due to light weight, small inertia, and quick response, the hydraulic device is easy to achieve quick start, braking and frequent reversing. The hydraulic transmission system is an integral part of hydraulic machinery. The design of the hydraulic transmission system should be carried out at the same time as the overall design of the main ...
