The emulsion pump station fluid supply system, as one of the important equipment of the fully-mechanized mining face of coal mines, provides power for the hydraulic supports of the fully-mechanized mining face. In the related technology, the variable frequency method used by the emulsion pump station to stabilize the pressure cannot respond to the pressure change in time due to the long control time, resulting in an increase in the pressure fluctuation amplitude. When multiple emulsion pump stations are running together, the effect of coordinated operation cannot be achieved.

Among them, the pressure sensor collects the pressure value of the emulsion main pipeline in real time; the main station controller obtains the pressure value of the emulsion main pipeline in real time and sends control instructions and adjustment instructions to the substation controller; the substation controller is used to monitor the operating status of the emulsion pump station, and transmit its data to the main station controller, and at the same time control the start and stop of the emulsion pump station and the status of the electromagnetic unloading valve; the emulsion main pipeline is used to transport the high-pressure emulsion output by the emulsion pump station to the comprehensive mining working face. Among them, the pressure of the emulsion main pipeline is the pressure of the pressure-stabilizing liquid supply control system of the emulsion pump station.
[0044] In the embodiment of the present application, the process of executing step 101 by the pressure-stabilizing liquid supply control device of the emulsion pump station is as follows: the pressure sensor collects the pressure value of the emulsion main pipeline, the main station controller obtains the pressure value of the emulsion main pipeline in real time to obtain a curve of the pressure change of the emulsion main pipeline with time, and measures the time that the pressure of the emulsion main pipeline is maintained while meeting the liquid demand of the comprehensive mining working face, thereby obtaining the current maintenance time.
[0045] In step 102, when the current maintenance time is less than the preset lower limit maintenance time, or the current maintenance time is greater than the preset upper limit maintenance time, a target emulsion pumping station in at least one emulsion pumping station and a target control instruction of the target emulsion pumping station are determined.
[0046] In the embodiment of the present application, the preset lower limit maintenance time and the preset upper limit maintenance time of the pressure value are pre-input into the pressure stabilizing liquid supply control system of the emulsion pump station, and can be calculated by a formula or set separately.
[0047] In an embodiment of the present application, when the current maintenance time is within the range of a preset lower maintenance time and a preset upper maintenance time of the pressure value, the current emulsion pump station operation can meet the liquid demand of the comprehensive mining working face. If the current maintenance time is less than the preset lower maintenance time, first determine any one of the at least one emulsion pump station in the shutdown state as the target emulsion pump station, and then determine the target control instruction of the target emulsion pump station as the start instruction. If the current maintenance time is greater than the preset upper maintenance time, first determine the last started emulsion pump station among the at least one emulsion pump station in the startup state as the target emulsion pump station, and determine the target control instruction of the target emulsion pump station as the shutdown instruction.
[0048] In step 103, the target emulsion pump station is controlled according to the target control instruction.
[0049] In an embodiment of the present application, the process of controlling the target emulsion pumping station according to the target control instruction may be: after determining the target control instruction of the target emulsion pumping station, if the target control instruction is a start instruction, the target emulsion pumping station is controlled to perform start processing; if the target control instruction is a shutdown instruction, the target emulsion pumping station is controlled to perform shutdown processing.
[0050] In an embodiment of the present application, the process of realizing the pressure-stabilized liquid supply function of the pressure-stabilized liquid supply control system of the emulsion pump station can be, for example, that the pressure sensor collects the pressure of the emulsion main pipeline in real time, the main station controller obtains the real-time pressure of the emulsion main pipeline and calculates the current pressure holding time of the emulsion main pipeline, and then determines the target emulsion pump station to be operated and the target control instructions of the target emulsion pump station, and sends the target control instructions to the substation controller, and the substation controller controls and processes the target emulsion pump station according to the target control instructions to realize the pressure-stabilized liquid supply of the emulsion pump station.
[0051] The method for controlling the pressure-stabilizing liquid supply of an emulsion pump station in an embodiment of the present application determines the current pressure value of the emulsion main pipeline and the current maintenance time of the current pressure value; when the current maintenance time is less than the preset lower limit maintenance time, or the current maintenance time is greater than the preset upper limit maintenance time, determines a target emulsion pump station in at least one emulsion pump station and a target control instruction of the target emulsion pump station; and controls and processes the target emulsion pump station according to the target control instruction, thereby improving the stability of the liquid supply pressure of the emulsion pump station, reducing the loss of the electromagnetic unloading valve, and extending the service life of the equipment in the pressure-stabilizing liquid supply system of the emulsion pump station.
[0052] Combine the following Figure 2 , the process of another method for controlling the pressure stabilizing liquid supply of an emulsion pump station provided in an embodiment of the present application is described.
[0053] Figure 2 It is a flow chart of another method for controlling the pressure-stabilizing liquid supply of an emulsion pump station according to an exemplary embodiment.
[0054] like Figure 2 As shown, the pressure-stabilizing liquid supply control method of the emulsion pump station may specifically include the following steps 201-204.
[0055] In step 201, the current pressure value of the emulsion main pipeline and the current maintenance time of the current pressure value are determined.
[0056] In step 202, when the current maintenance time is less than the preset lower limit maintenance time, a first emulsion pumping station is selected from at least one first emulsion pumping station in a shutdown state as a target emulsion pumping station; and the target control instruction is determined to be a start instruction.
[0057] In the embodiment of the present application, the first emulsion pumping station refers to an emulsion pumping station in a shutdown state, and the second emulsion pumping station refers to an emulsion pumping station in a startup state.
[0058] In an embodiment of the present application, when the current maintenance time is less than the preset lower limit maintenance time, the pressure stabilizing liquid supply control system of the emulsion pumping station does not meet the liquid demand of the comprehensive mining working face, and it is necessary to start the emulsion pumping station in the shutdown state to meet the start-up conditions of the emulsion pumping station. A first emulsion pumping station is selected from at least one first emulsion pumping station in the shutdown state as the target emulsion pumping station, and at the same time, its target control instruction is determined to be the start-up instruction.
[0059] In step 203, when the current maintenance time is greater than the preset upper limit maintenance time, the last started second emulsion pumping station is selected from at least one second emulsion pumping station in the startup state as the target emulsion pumping station; and the target control instruction is determined to be a shutdown instruction.
[0060] In an embodiment of the present application, when the current maintenance time is greater than the preset upper limit maintenance time, the pressure-stabilizing liquid supply control system of the emulsion pumping station also fails to meet the liquid demand of the comprehensive mining working face. It is necessary to stop the emulsion pumping station in the startup state to meet the shutdown conditions of the emulsion pumping station. The last started second emulsion pumping station is selected from at least one second emulsion pumping station in the startup state as the target emulsion pumping station. At the same time, its target control instruction is determined to be a shutdown instruction.
[0061] In step 204, the target emulsion pump station is controlled according to the target control instruction.
[0062] It should be noted that for the detailed description of steps 201 and 204, reference can be made to the description in other embodiments of the present application, and will not be described in detail here.
[0063] In summary, the pressure-stabilizing liquid supply control method of the emulsion pump station of the embodiment of the present application determines the current pressure value of the emulsion main pipeline and the current maintenance time of the current pressure value; when the current maintenance time is less than the preset lower limit maintenance time, selects a first emulsion pump station from at least one first emulsion pump station in a shutdown state as the target emulsion pump station; determines the target control instruction to be a start instruction; when the current maintenance time is greater than the preset upper limit maintenance time, selects the last started second emulsion pump station from at least one second emulsion pump station in a startup state as the target emulsion pump station; determines the target control instruction to be a shutdown instruction; and controls and processes the target emulsion pump station according to the target control instruction, thereby improving the stability of the liquid supply pressure of the emulsion pump station, reducing the loss of the electromagnetic unloading valve, and extending the service life of the equipment in the pressure-stabilizing liquid supply system of the emulsion pump station.
[0064] Combine the following Figure 3 , another method for controlling the pressure-stabilizing liquid supply of an emulsion pump station provided in an embodiment of the present application is described.
[0065] Figure 3 It is a flow chart of another method for controlling the pressure-stabilizing liquid supply of an emulsion pump station according to an exemplary embodiment.
[0066] like Figure 3 As shown, the following steps 301-309 may be specifically included.
[0067] In step 301, the current pressure value of the emulsion main pipeline and the current maintenance time of the current pressure value are determined.
[0068] In step 302, when the current maintenance time is less than the preset lower limit maintenance time, or the current maintenance time is greater than the preset upper limit maintenance time, a target emulsion pumping station in at least one emulsion pumping station and a target control instruction of the target emulsion pumping station are determined.
[0069] In step 303, the target emulsion pump station is controlled according to the target control instruction.
[0070] In step 304, at least one second emulsion pumping station in a startup state and the startup time of the second emulsion pumping station are determined.
[0071] In the embodiment of the present application, at least one second emulsion pumping station in the startup state is first determined according to the state of the emulsion pumping station, and the startup time of each second emulsion pumping station is determined at the same time.
[0072] In step 305, a start-up order of at least one second emulsion pumping station is determined according to the start-up time of at least one second emulsion pumping station.
[0073] In an embodiment of the present application, the starting order of at least one second emulsion pumping station is determined according to the starting time of each second emulsion pumping station. The first second emulsion pumping station started is the main pump by default, the second second emulsion pumping station started is the secondary pump, and the third second emulsion pumping station started is the auxiliary pump. The second emulsion pumping stations started afterwards are, for example, the second auxiliary pump, the third auxiliary pump, and so on.
[0074] In an embodiment of the present application, when there is a second emulsion pumping station whose state has changed in at least one second emulsion pumping station, at least one second emulsion pumping station in the startup state and the startup time of the second emulsion pumping station are redetermined; based on the startup time of at least one second emulsion pumping station, the startup order and pressure fluctuation range of at least one second emulsion pumping station are redetermined.
[0075] In step 306, the pressure fluctuation range corresponding to at least one second emulsion pumping station is determined according to the startup order of at least one second emulsion pumping station; wherein second emulsion pumping stations in different orders have different pressure fluctuation ranges.
[0076] In the embodiment of the present application, the lower limit value of the pressure fluctuation range is the boost pressure value, and the upper limit value of the pressure fluctuation range is the unloading pressure value.
[0077] In an embodiment of the present application, the pressure fluctuation range of the pressure-stabilizing liquid supply control system of the emulsion pumping station that meets the liquid demand of the comprehensive mining working face is pre-set, wherein the pressure fluctuation range of the pressure-stabilizing liquid supply control system of the emulsion pumping station that meets the liquid demand of the comprehensive mining working face is the pressure fluctuation range of the main pump, and the pressure fluctuation range of the main pump is unchanged.
[0078] Among them, the unloading pressure value of the main pump is greater than the unloading pressure value of the secondary pump; the unloading pressure value of the secondary pump is greater than the unloading pressure value of the auxiliary pump; the boosting pressure value of the auxiliary pump is greater than the boosting pressure value of the secondary pump; the boosting pressure value of the secondary pump is greater than the boosting pressure value of the main pump. Among them, the pressure fluctuation range of the secondary pump and the pressure fluctuation range of the auxiliary pump change with the pressure conversion rate of the emulsion pump station's pressure-stabilizing liquid supply control system, thereby achieving the best pressure control effect.
[0079] In the embodiment of the present application, the calculation formula of the pressure change rate β is:
[0080]
[0081] The boost pressure setting value calculation formula is:
[0082]
[0083] The calculation formula for the unloading pressure setting value is:
[0084]
[0085] Among them, in the above formula, P T is the current time pressure value, P t is the pressure value at the previous time, and Δt is the time change”
[0086] Quantity, K p is the boost proportional coefficient, ΔP i is the boost pressure gradient, Kp is the unloading proportional coefficient, and ΔPi is the unloading pressure gradient.
[0087] In step 307, the target second emulsion pumping station is determined based on the current pressure value and the pressure fluctuation range corresponding to at least one second emulsion pumping station; wherein the current pressure value is outside the pressure fluctuation range of the target second emulsion pumping station and is within the pressure fluctuation range of an adjacent second emulsion pump whose corresponding startup order is higher than that of the target second emulsion pump.
[0088] In the embodiment of the present application, when the current pressure value is outside the pressure fluctuation range of the target second emulsion pump station and is within the pressure fluctuation range of the adjacent second emulsion pump whose corresponding startup order is higher than the target second emulsion pump, the target second emulsion pump station is determined. For example, when the current pressure value is outside the pressure fluctuation range of the auxiliary pump but within the pressure fluctuation range of the secondary pump, the auxiliary pump is determined to be the target second emulsion pump station.
[0089] In step 308, a target adjustment instruction of the electromagnetic unloading valve of the target second emulsion pumping station is determined according to the current pressure value and the pressure fluctuation range of the target second emulsion pumping station.
[0090] In an embodiment of the present application, when the current pressure value is less than the lower limit pressure value in the pressure fluctuation range of the target second emulsion pump station, the target adjustment instruction is determined to be a boost adjustment instruction; when the current pressure value is greater than the upper limit pressure value in the pressure fluctuation range of the target second emulsion pump station, the target adjustment instruction is determined to be an unloading adjustment instruction.
[0091] In an embodiment of the present application, based on the current pressure value and the pressure fluctuation range of the target second emulsion pump station, when the current pressure value is less than the boost pressure value of the target emulsion pump station, the target adjustment instruction is determined to be an electromagnetic unloading valve closing instruction; when the current pressure value is greater than the unloading pressure value of the target emulsion pump station, the target adjustment instruction is determined to be an electromagnetic unloading valve opening instruction.
[0092] In step 309 , the electromagnetic unloading valve is controlled according to the target adjustment instruction.
