Excavator rotary motor, hydraulic system and control method
The invention provides an excavator rotary motor, a hydraulic system and a control method, the excavator rotary motor structurally comprises a motor main body, a first oil port and a second oil port, the first oil port is communicated with a first cavity of the motor main body, and the second oil port is communicated with a second cavity of the motor main body; the proportional valve is communicated with the first oil port and the second oil port; the control detection part is connected to the motor body, the control detection part can detect the pressure of the first oil port and the pressure of the second oil port, the control detection part is electrically connected with the proportional valve, and the control detection part can control the opening degree of the proportional valve; the first one-way valve is communicated with the first cavity and an oil tank of the excavator; and the second one-way valve is communicated with the second cavity and an oil tank of the excavator. The excavator rotary motor, the hydraulic system and the control method can solve the problem that an existing excavator rotary motor is difficult to meet use requirements.
本发明提供一种挖掘机回转马达、液压系统及控制方法，挖掘机回转马达的结构包括马达主体，设置有第一油口和第二油口，所述第一油口连通于所述马达主体的第一腔，所述第二油口连通于所述马达主体的第二腔；比例阀，连通于所述第一油口与所述第二油口；控制检测部，连接于所述马达主体，所述控制检测部能够检测所述第一油口和所述第二油口的压力，所述控制检测部与所述比例阀导电连接，所述控制检测部能够控制所述比例阀的开度；第一单向阀，连通于所述第一腔与所述挖掘机的油箱；以及第二单向阀，连通于所述第二腔与所述挖掘机的油箱。该挖掘机回转马达、液压系统及控制方法能够解决现有挖掘机回转马达难以满足使用需求的问题。
