Operation method of vacuum oil filter

Connect the oil circuit of the inlet and outlet oil pipes, turn on 380V, connect the safety ground wire, check whether each circuit is safely connected, whether the valves of each oil circuit are open, and then proceed to the operation procedure after preparation. First start the cooling water pump, check whether the water circuit circulation is normal, then jog the vacuum pump to make the oil in the vacuum pump run normally, and then make the vacuum pump run continuously. When the vacuum surface reaches the limit, the oil inlet valve can be opened until the oil surface is seen in the lower window of the vacuum cylinder, then the oil discharge pump switch is activated, the oil discharge and impurities are filtered, and the oil circuit is normally circulated. share. If there is a lot of water in the oil, the end of the oil in the vacuum cylinder will increase. At this time, the vacuum degree that is suitable for the venting control must be opened. When the moisture is reduced and the oil float has dropped, the venting valve will be closed to make the vacuum reach the limit. At this time, pay attention to the reaction of each instrument. If the reading of the pressure gauge is greater than 0.3MPa, it means that the filter paper in the filter has absorbed more impurities and needs to be replaced with a new filter paper. The vacuum degree reaches the normal atmospheric pressure. After the oil in the cylinder is drained, the remaining oil is released from the oil drain plug to prevent it from being mixed into different types of oil in the next use. In winter, pay special attention to drain the water in the vacuum pump and the water tank. , otherwise the vacuum pump and water storage tank will be frozen.
