Abstract

The embodiment of the invention provides a hydraulic system, an excavator and a control method, and relates to the engineering equipment technology field. The hydraulic system comprises a controller,a power pump, an electric control stop valve, an oil inlet pipe and an oil tank. The electric control stop valve is arranged on a pipeline of the power pump and the oil tank, the oil inlet pipe is connected with the power pump, hydraulic oil in the oil tank is pumped into the oil inlet pipe through the power pump, and the oil inlet pipe is used for being connected with a breaking hammer so as to supply oil to the breaking hammer. When maintenance is needed, the oil tank can be separated from the pipeline only through closing the electric control stop valve, the hydraulic oil of a whole machinedoes not need to be pumped, secondary pollution to the hydraulic oil in a maintenance process can be effectively avoided, and maintenance is more convenient and fast. The controller is electrically connected with the electric control stop valve and is used for controlling the electric control stop valve so that opening and closing of the electric control stop valve are intelligently controlled through the controller, and fool-proof and mistake-proof problems in a use process of a user are solved.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a hydraulic system, an excavator and a control method. Background technique [0002] Excavator is one of the most widely used construction machinery in engineering construction. The excavator mainly uses hydraulic drive to work. [0003] In the repair and maintenance process of the existing excavator, the maintenance personnel need to extract the hydraulic oil of the whole machine when repairing the whole machine, which wastes maintenance time. At the same time, the process of disassembling the oil tank will easily cause secondary pollution of the hydraulic oil. Contents of the invention [0004] The purpose of the present invention includes, for example, providing a hydraulic system, which can improve the technical problem of time-consuming excavator maintenance in the prior art. [0005] The object of the present invention also includes providing an excavator, ...
