The invention provides a multifunctional hydraulic system. The multifunctional hydraulic system comprises a first oil supply loop, a second oil supply loop, a third oil supply loop, a speed regulation loop, a locking loop, a decompression loop, a volume speed modulating loop, a flowmeter, a cooler, a control box and an oil tank, wherein the first oil supply loop, the second oil supply loop and the third oil supply loop are connected in parallel and together supply oil for the multifunctional hydraulic system; the flowmeter generates a signal and sends the signal to the controller; the controller processes the signal and then generates a control signal to control the attraction and separation of electromagnets; and a variable pump of the second oil supply loop and an adjustable-speed motor of the third oil supply loop are controlled to regulate the flow rate. By adoption of the scheme, the advantages of all speed regulation modes are synthesized, and the speed regulation modes can be selected according to different working conditions; the speed regulation loop, the locking loop and the decompression loop can be connected with not only the same oil cylinder to satisfy different working requirements so as to achieve flexibility and changeability but also different oil cylinders, and together with a bidirectional variable motor in the volume speed modulating loop, combined operation is conducted to realize complicated movement.
Description
technical field [0001] The invention belongs to the technical field of hydraulic control, and in particular relates to a multifunctional hydraulic system, which is applicable to the complex motion of a single actuator and the coordinated motion of multiple actuators. Background technique [0002] Multifunctional hydraulic systems are generally customized according to site requirements because they are oriented to different application conditions.
