Embodiment

[0038] Example: such as figure 1 As shown, it is a kind of unattended emulsion pump automatic control system disclosed by the present invention, comprising:

[0039] The pressure supply device 100 is used to provide the emulsion with pressure for the hydraulic strut, so as to make the hydraulic strut work;

[0040] The liquid supply device 101 replenishes the consumed emulsion for the pressure supply device 100;

[0041] The control device 102 is used to control the start and stop of the pressure supply device 100 and the liquid supply device 101 to realize automatic control.

[0042] Such as figure 1As shown, the pressure supply device 100 includes an emulsion pump 103 and an emulsion tank 104 . There are two emulsion pumps 103, and the liquid inlets of both are communicated with the emulsion tank 104 through a three-way joint. The liquid outlets of the two emulsion pumps 103 are connected with a liquid supply pipe 106 through a three-way joint. One end of the liquid sup...

Abstract

The invention discloses an automatic control system for an unattended emulsion pump, belongs to the technical field of hydraulic pumping stations. The automatic control system includes a pressure supply device and a control device. The pressure supply device includes an emulsion pump and an emulsion tank. The inlet of the emulsion pump is in communication with the emulsion tank, the liquid outletof the emulsion pump is connected with a liquid supply pipe, and the liquid supply pipe is equipped with a one-way valve. The control device includes a detection component that detects the oil pressure in the hydraulic prop and a PLC which is electrically connected to the detection component. The PLC is electrically connected to the motor of the emulsion pump. When the detection component detectsthat the oil pressure in the pressure strut fluctuates, the PLC outputs a control signal to control the operation of the emulsion pump motor; when the detection component detects the pressure support,the internal oil pressure does not fluctuate within T time, and the PLC outputs a control signal to control the motor of the emulsion pump to stop working. The invention has the effect of saving energy.

Description

technical field [0001] The present invention relates to the technical field of emulsion pumping station, more specifically, it relates to an unattended emulsion pump automatic control system. Background technique [0002] The emulsion pump station is used to provide the hydraulic pressure source for the hydraulic prop in the mine. The hydraulic prop refers to a retractable prop that uses liquid pressure to generate working resistance and realize lifting and unloading. It is used together with the metal top beam, and it can also be used as a point column alone to support the roof of the general mechanized working face of the coal mine, or for the end support of the comprehensive mechanized working face and other temporary supports. [0003] At present, a mining emulsion pumping station system includes an emulsion tank, an emulsion pump, a liquid supply pipe and a liquid injection gun connected in sequence. The emulsion pump delivers the emulsion in the emulsion tank to the l...
