The pump station described in the application is a device for providing hydraulic power for a coal mining machine. The pump station is an important part of the electric traction coal mining machine, mainly providing hydraulic power for the height adjustment system of the coal mining machine to help adjust the height of the coal mining machine to adapt to different coal seam thickness. At the same time, the brake control oil for the walking part is provided. The pump station is mainly composed of a valve group, an oil tank and a motor device. The circuit includes:

[0045] In the embodiment of the present application, the emulsion tank station simulation unit specifically comprises:

[0046] The emulsion tank station display screen, the emulsion tank station circuit breaker, the emulsion tank station control relay, the emulsion tank station keyboard, the emulsion tank station button junction box, the emulsion tank station switching power supply, the emulsion tank station booster pump running fan and the emulsion tank station intrinsic safety power supply are connected with the Mine Hong controller.

[0050] The spray water tank station display screen, the spray water tank station circuit breaker, the spray water tank station control relay, the spray water tank station keyboard, the spray water tank station button junction box, the spray water tank station switching power supply, the spray pump station cooling pump running fan and the spray water tank station intrinsic safety power supply are connected with the Mine Hong controller.

[0051] In the above, each substation analog unit is connected with the mine controller, and the connection mode is specifically that a link aggregation module in the mine controller is connected with a display screen in each substation analog unit through an Ethernet network cable, a digital quantity input module in the mine controller is connected with an emergency stop signal, a start signal, a stop signal, a near control signal, a remote control signal and a feedback signal of a control relay of a button junction box in each substation analog unit, a keyboard input module in the mine controller is connected with a metal keyboard in each substation analog unit, a digital quantity output module in the mine controller is connected with the control relay in each substation analog unit, and a current analog quantity input module in the mine controller is connected with a current generating unit in each substation analog unit.

[0052] Taking the emulsifying pump station analog unit as an example, after the display screen, the mine controller and the current generator are powered on, the mine controller will collect the emergency stop, start, stop, near control and remote control signal states on the button junction box, then collect the 4-20ma current corresponding to the oil pressure, oil level and oil quality of the current generating unit, then collect the resistance value corresponding to the oil temperature of the PT100 unit, and then transmit the data to the display screen. Then the CPU module of the mine controller judges whether the current emulsifying pump meets the pump starting condition according to the threshold values of the oil pressure, oil level, oil quality and oil temperature set in the program. If all the data meet the requirements, the display screen will display normally.

[0053] Each substation analog unit and the mine controller have a link aggregation module, which is a communication module for data interaction between stations and between the controller and the display screen. The digital quantity input module mainly collects external switch quantity signals, such as the current emergency stop, start, stop, near control, remote control and running feedback signals. The keyboard input module is also a digital quantity input module, which mainly collects the input signals of the metal keyboard. The digital quantity output module mainly outputs signals to control the relay coil. After the relay coil is powered on, the relay contact is closed to give a main pump motor running pilot signal. After the main pump switch cabinet receives the main pump motor running pilot signal, the main pump motor is powered on and the main pump motor runs. The current analog quantity input module mainly collects 4-20 current values of oil pressure, oil level, oil quality and the like, thereby converting them into corresponding pressure, liquid level and quality values, to enable the mine controller to judge whether the current main pump motor is running normally.
