The invention discloses a
machine tool lubricating oil circulating device which is used for performing dynamic circulation on lubricating oil in a lubricating
oil tank of a
machine tool and comprises an oil-well pump, an oil delivery pump, an
oil storage tank, an oil
mass detector, a temperature
detector and a control device, wherein an oil inlet of the oil-well pump is communicated with a pipeline of the lubricating
oil tank, and an oil outlet of the oil-well pump is communicated with a pipeline of the
oil storage tank; an oil inlet of the oil delivery pump is communicated with a pipeline of the
oil storage tank, and an oil outlet of the oil delivery pump is communicated with a pipeline of the lubricating
oil tank; the lubricating oil tank, the oil-well pump, the oil
storage tank and the oil delivery pump constitute a lubricating oil dynamic circulation loop; the temperature
detector is mounted on the lubricating oil dynamic circulation loop; the oil
mass detector is mounted in the lubricating oil tank; the control device is in communicating connection with the oil-well pump, the oil delivery pump, the oil
mass detector and the temperature detector; the temperature detector is used for detecting temperature of the lubricating oil; the oil mass detector is used for detecting oil mass in the lubricating oil tank; the control device obtains the oil mass information and the lubricating
oil temperature information in the lubricating oil tank through the oil mass detector and the temperature detector.
