Embodiment Construction
[0012] The present invention will be further described below in conjunction with embodiment.
[0013] Depend on figure 1 It can be seen that the oil tank liquid level monitoring device of the oil hydraulic machine is composed of the pressure oil tank 12, the liquid level monitoring mechanism and the PLC controller. The liquid level monitoring mechanism is composed of the connecting pipe 3, the magnetic buoy 5 and the displacement sensor. The monitoring mechanism is provided with an oil inlet hole, which cooperates with the flange 9 provided on the outer wall of the oil tank, and is fixed on the oil tank by a washer 10 and a bolt 11; the displacement sensor is electrically connected with the PLC controller placed in the control room.
[0014] Depend on figure 1 It can also be seen that the two ends of the connecting pipe 3 of the liquid level monitoring mechanism are circular, and through holes are arranged on the circular ring, and the screws 2 are respectively connected with...

The invention provides an oil hydraulic press tank level monitoring device, belongs to the technical field of liquid level indicators, and particularly relates to an indicating device magnetically operated. The oil hydraulic press tank level monitoring device is characterized by comprising a pressure oil tank, a level monitoring mechanism and a PLC. The level monitoring mechanism is composed of a communicating pipe, a magnetic float and a displacement sensor. The monitoring mechanism is provided with an oil inlet, matches with a flange arranged on the outer wall of the oil tank, and is fixed on the oil tank through gaskets and bolts. The displacement sensor is electrically connected with the PLC located in a control chamber. The oil hydraulic press tank level monitoring device has the advantages that conception is novel, and structure is compact and reasonable; by means of the displacement sensor, the alarm level and pump trip level of the oil tank level can be controlled accurately in the millimeter range through programming; when oil of the hydraulic system leaks, alarming signals can be sent timely, a large amount of oil leakage can be avoided, oil can be saved, production cost can be lowered, environment pollution can be reduced, hydraulic oil can be resupplied timely, and production can be guaranteed smoothly.
Description
technical field [0001] The invention belongs to the technical field of liquid level indicators, in particular to a magnetically operated indicating device. Background technique [0002] The hydraulic oil in the oil tank of the hydraulic machine, due to the up and down movement of the main cylinder of the hydraulic machine, the change of the oil volume of more than 4,000 liters of hydraulic oil and the cause of the oil leakage will cause drastic changes in the liquid level, resulting in oil leakage that cannot be found in time and affects other hydraulic machines. normal work. At present, the liquid level monitoring of the oil tank adopts the external sensor magnetic flip column liquid level gauge or the magnetic float hydraulic gauge to monitor the liquid level. The disadvantage is that when oil leakage occurs in the hydraulic system of the press, an accurate alarm cannot be made through the current liquid level, resulting in a large amount of external leakage of the hydrau...
