Embodiment Construction
[0014] An automatic liquid filling and draining system for a liquid filling tank: at least including a liquid filling tank 11, an oil supply circuit connected to the liquid filling tank 11, an oil discharge circuit connected to the liquid filling tank 11 and a working mechanism for supplying working oil to the working cylinder 3 The oil circuit, the liquid filling tank 11 is connected with a liquid level sensor and a pressure charging circuit. During operation, the pressure charging circuit fills the liquid filling tank 11 with an air pressure of 0.3-0.5MPa, and the liquid level sensor detects the oil level of the liquid filling tank 11. When When the oil level is lower than the low oil level, the electric control unit 5 controls the oil supply circuit to supply oil to the liquid filling tank 11, so that the oil level of the liquid filling tank 11 handles the working oil level range. When it is higher than the high oil level point of the liquid filling tank 11, The operation of...
