[0008] Furthermore, the main body, intermediate tube, and end cap are all made of nylon composite fiber material.

[0009] As a third preferred embodiment of this utility model, the base is provided with a wire take-up hole, through which the signal line of the magnetoelectric sensor can pass.

[0010] Furthermore, the take-up holes are provided in multiple shapes, distributed circumferentially on the base.

[0011] As a fourth preferred embodiment of this utility model, the base is provided with a directional positioning groove.

[0012] A diaphragm pump using the aforementioned oil replenishment / discharge signal sensor device includes a pump body, a rubber diaphragm disposed within the pump body, a diaphragm chamber between the rubber diaphragm and the pump body, a guide rod disposed on one side of the rubber diaphragm within the diaphragm chamber, and a permanent magnet ring disposed on the guide rod. The pump body is characterized by having a sheath corresponding to the permanent magnet ring, the housing of the oil replenishment / discharge signal sensor being disposed within the sheath, and an outer sleeve disposed outside the housing to fix the sheath within the pump body. The outer sleeve is connected to the base of the oil replenishment / discharge signal sensor; the signal line of the oil replenishment / discharge signal sensor passes through a take-up hole in the base and a hole on the outer sleeve corresponding to the take-up hole in the base, and is connected to a control system.

[0013] The beneficial effects of this utility model are as follows: 1. By combining two magnetoelectric sensors, dynamic monitoring of the oil content in the diaphragm chamber can be achieved, which can promptly determine whether the oil needs to be replenished or discharged, thus ensuring the stability and reliability of the system operation.

[0014] 2. The movement of the guide rod is monitored in real time by a magnetoelectric sensor to ensure the dynamic balance of the oil in the diaphragm chamber, avoid abnormal operation of the equipment due to excessive or insufficient oil content, and improve the service life and stability of the diaphragm pump.

[0015] 3. Through feedback from sensor signals, the system can accurately control the oil injection and discharge process, avoid excessive or insufficient oil, reduce unnecessary energy consumption, and improve the overall operating efficiency of the equipment.

[0016] 4. The shell structure made of nylon composite fiber can protect the sensor and adapt to complex field working conditions, ensuring that the equipment can operate stably for a long time.

[0017] 5. Through automatic detection and signal feedback, the oil management process of the diaphragm chamber is automated, reducing manual intervention, improving the system's intelligence level, and reducing maintenance costs.

[0018] 6. When the oil content is abnormal, the magnetoelectric sensor can send a signal to the control system to adjust the oil status in time, avoid damage to the equipment due to abnormal oil, and improve the safety and reliability of the equipment. Attached Figure Description

Detailed Implementation

[0024] This utility model includes a housing 10 with one open end and the other closed end. A base 1 is provided at one open end of the housing 10. The feature is that two magnetoelectric sensors 8 are arranged adjacent to each other inside the other end of the housing 10. The signal lines 5 of the two magnetoelectric sensors 8 extend from one open end of the housing 10.

[0025] The housing 10 is provided with a through hole 7 corresponding to the magnetoelectric sensor 8. By providing the through hole 7, it is convenient to observe whether the magnetoelectric sensor 8 is installed in place during assembly. The magnetoelectric sensor 8 has a working light, which can be easily observed during assembly through the through hole 7.

[0026] The housing 10 has a process elongated hole 4 in the middle. The process elongated hole 4 facilitates the processing of this utility model. At the same time, when this utility model is assembled on the diaphragm pump and is working normally, if testing is required, the outer jacket 19 can be removed, and the working light of the magnetoelectric sensor 8 can be observed through the process elongated hole 4.

[0027] The housing 10 includes a main body 3, one open end of which is connected to the base 1 via a thread; the other end of the main body 3 is connected to one end of an intermediate tube 6 via a thread, a through hole 7 is provided on the intermediate tube 6, and two threaded holes for cooperating with magnetoelectric sensors 8 are provided inside the other end of the intermediate tube 6; the two magnetoelectric sensors 8 are respectively disposed in the two threaded holes; an end cap 9 is provided on the outside of the other end of the intermediate tube 6 via a thread. The structure is reasonable and easy to assemble and maintain.

[0028] The main body 3, intermediate tube 6, and end cap 9 are all made of nylon composite fiber material. Compared with metal materials, it is lighter and has good corrosion resistance, making it suitable for various complex working environments.

[0029] The base 1 is provided with a wire take-up hole 2, through which the signal line 5 of the magnetoelectric sensor 8 can pass.

[0030] Multiple cable take-up holes 2 are provided and distributed circumferentially on the base 1. By providing multiple cable take-up holes 2 on the base 1 and distributing them circumferentially, the signal cable 5 can pass through more flexibly, improving the neatness of the wiring, avoiding cable tangling, and improving the overall reliability of the equipment.

[0031] The base 1 is provided with a directional positioning groove. The directional positioning groove on the base 1 enables the sensor to be accurately positioned during installation, ensuring the correctness of its detection angle and position.

[0032] A diaphragm pump using the aforementioned oil replenishment / discharge signal sensor device includes a pump body, a rubber diaphragm 16 disposed within the pump body, a diaphragm chamber between the rubber diaphragm 16 and the pump body, a guide rod 15 disposed on one side of the rubber diaphragm 16 within the diaphragm chamber, and a permanent magnet ring 12 disposed on the guide rod 15. The pump body is characterized by having a sheath 18 corresponding to the permanent magnet ring 12; the housing 10 of the oil replenishment / discharge signal sensor is disposed within the sheath 18; an outer sleeve 19 is disposed outside the housing 10 to fix the sheath 18 within the pump body; the outer sleeve 19 is connected to the base 1 of the oil replenishment / discharge signal sensor; the signal line 5 of the oil replenishment / discharge signal sensor passes through the take-up hole 2 of the base 1 and a hole on the outer sleeve 19 corresponding to the take-up hole 2 of the base 1, and is connected to the control system.

[0033] like Figure 3 , Figure 4 As shown, before the present invention is put into operation, the permanent magnet ring 12 is located within the detection range of the right-side magnetoelectric sensor 14. Oil is injected into the diaphragm chamber, and the guide rod 15 moves to the left and enters the detection range of the left-side magnetoelectric sensor 13. Oil injection continues, and the magnetic field sensed by the electromagnetic sensor 14 disappears. Oil injection continues, and the magnetic field sensed by the magnetoelectric sensor 13 disappears. The magnetoelectric sensor 13 sends a signal, and the control system controls the diaphragm pump to work normally, and the guide rod 15 performs reciprocating motion.

[0034] During normal operation, the magnetoelectric sensor 13 detects a signal once per cycle in each period of the guide rod 15, while the magnetoelectric sensor 14 fails to detect a signal. When one or more cycles fail to detect a signal, the magnetoelectric sensor 13 sends an oil discharge signal to drain excess oil, ensuring that the magnetoelectric sensor 13 detects a signal once per cycle. When the magnetoelectric sensor 14 detects a signal, it sends a signal to the control system to replenish oil, ensuring that the magnetoelectric sensor 14 fails to detect a signal.
