Description

Technical Field

[0001] This utility model relates to the field of petroleum equipment technology, and in particular to a control structure for an electromagnetic valve group based on a liquid supply plunger pump skid. Background Technology

[0002] Liquid supply plunger pump skids are widely used in the industrial field. The on / off state of the solenoid valve group in the suction manifold varies under different working conditions. However, the disadvantages are also obvious: First, conventional liquid supply equipment often requires experienced operators to select the position and number of pneumatic solenoid valves to open to determine the flow direction of the manifold. This places too high demands on the on-site personnel, and the switching process is cumbersome and prone to omission or accidental opening. Second, conventional liquid supply equipment is adapted to a single working condition. Each set of equipment may be idle after being used in a specific situation, resulting in a lot of waste.

[0003] Therefore, it is necessary to propose an improvement to overcome the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by providing a solenoid valve group control structure based on a liquid supply plunger pump skid, thereby solving the problems of manifold flow direction and resource waste in industrial equipment.

[0007] The above technical solution includes a local controller and a remote controller. The local controller is connected to an I / O module, which is connected to the solenoid valve assembly on the industrial equipment. The remote controller is installed in a remote control box.

[0011] As a preferred technical solution, the touch screen includes a local touch screen and a remote touch screen, with the remote touch screen located inside the remote control box.

[0020] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Example 1:

[0022] like Figure 1 and Figure 2 The diagram shown is the hardware logic diagram and control logic diagram of the electromagnetic valve group control structure based on the liquid supply plunger pump skid of this utility model.

[0023] The solenoid valve group control structure of this embodiment based on a liquid supply plunger pump skid includes a touch screen 1, a remote control box 2, a wireless gateway 3, a controller 4, an I / O module 5, an angle sensor 6, and a solenoid valve group 7. The controller 4 includes a remote controller and a local controller, which are connected. The touch screen 1 includes a remote touch screen and a local touch screen. The control box 2 includes a remote control box and a local control cabinet. The remote controller is installed in the remote control box, and the local controller is installed in the local control cabinet. The remote touch screen and the local touch screen are integrated into the remote control box and the local control cabinet, respectively. The controller is connected to the I / O module 5, and the I / O module 5 is connected to the solenoid valve group 7. The angle sensor 6 is installed on the solenoid valve group 7 and is connected to the I / O module 5.

[0024] The control of the solenoid valve group switching in this system uses a PLC as the controller (I / O module) and a touch screen and remote control box as the control terminals. All solenoid valves are controlled by the digital output function of controller 4. The screen of touch screen 1 can preset which solenoid valves need to be opened or closed under different working conditions, or it can be set manually. Then, the design is stored in the system through the digital storage function. Later, the stored settings can be selected and retrieved from the list. The manifold diagram will also change synchronously. After the solenoid valve is opened, the screen will only display the manifold related to the opened solenoid valve and automatically calculate and simulate the flow direction, making the screen display more intuitive and concise during construction.

[0025] The valve group status is controlled and displayed via touch screen 1 or remote control box. The on / off status of all valves will be displayed in the flowchart on the screen. Operators can customize the status of each solenoid valve corresponding to the manifold in advance according to different working conditions. When needed, the appropriate setting can be selected from the list to immediately switch to the corresponding manifold schematic interface. At the same time, the system adjusts the engine speed, gearbox gear and centrifugal pump speed according to the settings.

[0026] This system employs an advanced angle sensor 6 to transmit the real-time switching status of all solenoid valves to the controller 4. The angle sensor 6 is mounted on the valve block to monitor its physical properties and determines whether the valve block is damaged by rotating its angle. If the corresponding solenoid valve fails to operate after the settings are selected and the valve is opened, the system will immediately alarm and prompt the operator to check. Conversely, when the controller 4 detects solenoid valve operation during a pre-set work process, the system will display a prompt and alarm, causing the engine to idle urgently, the transmission to return to neutral, and prompting the operator to check the equipment.

[0027] The remote control box of this system is equipped with a remote touchscreen, which functions identically to the local touchscreen, allowing for remote control of all settings and significantly increasing safety during high-voltage operations. It also enables control from startup to completion of operations. The system also utilizes a wireless gateway 3 to collect and upload data from the field control system and the operating status of the solenoid valve group 7. This data is transmitted in real-time to a cloud server for viewing. Equipment operators can log in to a webpage via mobile phone or computer to view the equipment's operating status in real time, while administrators can remotely control the equipment's start-up, shutdown, and related operations.

[0028] The steps for the equipment startup test method of this utility model are as follows:

[0029] 1. Turn on the computer and check if the data is normal.

[0030] 2. Test whether each solenoid valve operates normally. Select 2-3 preset groups and switch between them to check whether the valve group operates synchronously.

[0031] 3. Select the settings in advance and start the equipment for construction.

[0032] 4. Monitor the status of each parameter to ensure stable equipment operation.

[0033] 5. After the equipment has been running without faults for 3 hours, the equipment should be shut down in sequence and the equipment operation data should be compiled.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
