Description

Technical Field

[0001] This utility model belongs to the field of plunger pump technology, and in particular relates to a plunger pump condition monitoring device. Background Technology

[0002] A piston pump is a widely used device in hydraulic systems. Its core working principle is to change the volume of the sealed working cavity by the reciprocating motion of the piston in the cylinder, thereby achieving the functions of oil suction and pressure. During the operation of the piston pump, a monitoring device is used to monitor its working status so that any malfunctions can be dealt with promptly to avoid significant losses.

[0003] However, the commonly available plunger pump condition monitoring devices on the market have limited monitoring functions, making it difficult to provide more comprehensive and sufficient safety monitoring of the plunger pump. They also cannot provide timely alerts for abnormal operation, posing potential risks. For example, in the utility model patent with publication number CN221373873U, a vibration sensor with an appropriate installation is used to generate a plunger pump identification signal, but it can only monitor the vibration status of the plunger pump. Therefore, there is an urgent need to improve the existing plunger pump condition monitoring devices. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a plunger pump condition monitoring device that detects pressure and vibration during plunger pump operation and provides real-time audible and visual alarms through an alarm system, offering more comprehensive and thorough safety warnings. In addition, it can push detection data and alarm information to the user's mobile phone via the cloud.

[0005] The technical solution of this utility model is: a plunger pump status monitoring device, including a plunger pump body, with multiple oil pipes at the end of the plunger pump body, and a monitoring system, which includes a controller and a touch display module electrically connected to the controller. Each of the oil pipes has an external connecting pipe at its outer edge that communicates with the oil pipe and is connected to a pressure monitoring component via the external connecting pipe. The pressure monitoring component is electrically connected to the controller. A vibration sensor is also fixedly installed on the outside of the plunger pump body and is electrically connected to the controller.

[0006] Preferably, the pressure monitoring component includes a pressure sensing probe and a sealing plate sleeved on the outer side of the end of the pressure sensing probe. The outer edge of the oil pipe is provided with a sealing flange that mates with the sealing plate. The pressure sensor is inserted into the outer pipe through the inner hole of the sealing flange, and the sealing plate and the sealing flange are detachably connected by bolts.

[0007] Preferably, both the pressure sensing probe and the vibration sensor are electrically connected to the controller via signal lines.

[0008] Preferably, the controller has a first connector, and the end of the signal line has a second connector that is detachably fitted outside the first connector and electrically connected to the first connector.

[0009] Preferably, the outer wall of the middle part of the first connector is provided with an arc-shaped concave groove, and the middle part of the second connector is provided with a through ball groove corresponding to the position of the arc-shaped groove, and a positioning ball that cooperates with the concave groove is movably installed in the ball groove. The outer side of the second connector is slidably fitted with a movable tube that limits the positioning ball, and a spring is provided between the movable tube and the end of the second connector.

[0010] Preferably, the inner wall surfaces at both ends of the ball groove are arc-shaped, and the opening width at both ends of the ball groove is smaller than the diameter of the positioning ball, and the inner diameter of the front end of the movable tube is larger than its inner diameter at the rear end.

[0011] Preferably, the alarm system further includes a cloud server that establishes a network connection with the mobile phone, and pushes information to the mobile phone through the cloud server. Compared with the prior art, this utility model has the following advantages: This solution is equipped with a vibration sensor and multiple pressure sensing probes, which can monitor the vibration intensity and oil pipe sealing in real time during the operation of the plunger pump body, so as to provide more comprehensive and sufficient safety monitoring of the plunger pump body and ensure the safe and stable operation of the plunger pump body. Data monitored by vibration sensors and multiple pressure sensors can be transmitted to the controller via signal lines and displayed on a touch screen module for easy viewing by operators. Information can also be pushed to mobile phones via the cloud. Furthermore, the controller can be set to provide alarm prompts when data exceeds the range via the touch screen module. The second connector and the first connector are designed for quick installation and quick removal, making the connection more convenient and flexible. Under the contact of the inner wall of the movable tube, the bottom of the positioning ball can engage with the concave groove, thereby stably connecting the two connectors and preventing accidental breakage that could affect monitoring. When the movable tube is manually moved towards the end, the resistance of the positioning ball can be released. Then, the second connector can be manually pulled out to separate it from the first connector. In addition, this design makes the connection between the two connectors more stable and reliable through the engagement of the positioning ball and the concave groove. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0014] like Figures 1 to 3 A plunger pump status monitoring device includes a plunger pump body 1, a monitoring system, and an alarm system.

[0015] The monitoring system includes a controller 7 and a touch display module 8 electrically connected to the controller 7.

[0016] The plunger pump body 1 has multiple oil pipes 3 at its end. Each oil pipe 3 has an external pipe 4 connected to the oil pipe 3 at its outer edge. The pressure monitoring component 5 is connected to the pressure monitoring component 5 through the external pipe 4. The pressure monitoring component 5 is electrically connected to the controller 7. A vibration sensor 2 is also fixedly installed on the outside of the plunger pump body 1. The vibration sensor 2 is electrically connected to the controller 7.

[0017] The alarm system includes a light alarm and a sound alarm, both of which are electrically connected to the controller 7.

[0018] The pressure monitoring component 5 includes a pressure sensing probe 17 and a sealing plate 18 sleeved on the outside of the end of the pressure sensing probe 17.

[0019] The outer end of the oil pipe 3 is provided with a sealing flange 19 that mates with the sealing plate 18. The pressure sensor is inserted into the outer pipe 4 through the inner hole of the sealing flange 19, and the sealing plate 18 and the sealing flange 19 are detachably connected by bolts.

[0020] Working principle: First, the vibration sensor 2 is fixedly installed on the top of the plunger pump body 1. Then, multiple pressure sensor probes 17 are inserted into the corresponding external pipes 4 and sealed with the sealing flange 19 and the sealing plate 18. Subsequently, the vibration sensor 2 and multiple pressure sensor probes 17 are connected to the controller 7 via signal lines 6. Through the vibration sensor 2 and multiple pressure sensor probes 17, the vibration intensity of the plunger pump body 1 and the sealing of the oil pipe 3 during operation can be monitored in real time, which facilitates more comprehensive and sufficient safety monitoring of the plunger pump body 1 and ensures the safe and stable operation of the plunger pump body 1. The touch display module 8 facilitates the display of data obtained from the vibration sensor 2 and multiple pressure sensor probes 17, making it convenient for operators to view. Information can also be pushed to mobile phones via the cloud. The touch display module 8 can also be used to set the controller 7 to provide alarm prompts when data exceeds the range, so that alarms can be triggered in time when problems occur.

[0021] It should be noted that the vibration sensor 2, pressure sensor probe 17, controller 7, touch display module 8 and processor 9 in this solution are all existing devices. Their specific structures and working principles are all mature existing technologies, which are directly referenced in this case and will not be described in detail. Example 2

[0022] This embodiment is a further optimization based on the above embodiment, specifically: like Figures 1 to 4 The pressure sensor probe 17 and the vibration sensor 2 are both electrically connected to the controller 7 via the signal line 6.

[0023] The controller 7 is provided with a first connector 10, and the end of the signal line 6 is provided with a second connector 12 that is detachably fitted outside the first connector 10 and electrically connected to the first connector 10.

[0024] The outer wall of the middle part of the first connector 10 is provided with an arc-shaped concave groove 11, and the middle part of the second connector 12 is provided with a through ball groove 13 corresponding to the position of the arc-shaped groove. A positioning ball 14 that cooperates with the concave groove 11 is movably installed in the ball groove 13.

[0025] The outer side of the second connector 12 is provided with a movable tube 15 that limits the positioning ball 14, and a spring 16 is provided between the movable tube 15 and the end of the second connector 12.

[0026] Both ends of the inner wall of the ball groove 13 are arc-shaped, and the opening width at both ends of the ball groove 13 is smaller than the diameter of the positioning ball 14.

[0027] Working principle: After the first connector 10 and the second connector 12 are plugged in, the bottom part of the positioning ball 14 can be stably engaged in the concave groove 11 under the contact of the inner wall of the movable tube 15, so that the first connector 10 and the second connector 12 are stably connected and avoid accidental breakage that would affect the monitoring.

[0028] When the movable tube 15 is moved manually, the movable tube 15 is disengaged from the positioning ball 14. Then the second connector 12 is manually pulled out and separated from the first connector 10. Alternatively, the inner diameter of the front end of the movable tube 15 can be designed to be larger than that of the rear end. When the movable tube 15 is dragged to the end, the front end of the movable tube 15 reaches the positioning ball 14. Since the inner diameter of the front end is larger, it can release the resistance to the positioning ball 14, and the second connector 12 can be pulled out.

[0029] This design sets the first connector 10 and the second connector 12 as quick-install and quick-release devices, making the connection more convenient and flexible. In addition, the design makes the connection between the two connectors more stable and reliable by engaging the positioning ball 14 with the concave groove 11. Example 3

[0030] This embodiment is a further optimization based on the above embodiment, specifically: In this embodiment, the alarm system also includes a cloud server that establishes a network connection with the mobile phone and pushes information to the mobile phone through the cloud server.

[0031] Currently, a cloud server has been established at the Shengli Oilfield operation site. This cloud server has the functions of mobile terminal network interconnection and PC terminal network interconnection. Therefore, by connecting the controller 7 of this utility model with the existing cloud server of the oilfield, a signal connection can be established to the mobile phones or computers of the operators through the cloud server, making it more convenient to use.

[0032] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
