Description

Technical Field

[0001] The utility model relates to the technical field of emulsion pump monitoring, in particular to a crankcase temperature monitoring device of an emulsion pump. Background Art

[0002] Emulsion pumps are widely used in hydraulic systems in mining, machinery, metallurgy and other fields. They are used to provide a stable supply of emulsion and are important components to ensure the normal operation of equipment. As a key equipment in the hydraulic system, the emulsion pump generates high temperature due to high-speed operation and mechanical friction during long-term operation. If the temperature abnormality in the crankcase cannot be monitored and handled in time, it is easy to cause equipment overheating, lubricating oil deterioration and other problems.

[0003] The crankcase is one of the core structures of the emulsion pump. Its internal components are most likely to generate a large amount of heat during operation under high-intensity and high-frequency working conditions. If its temperature changes cannot be grasped in time, it will lead to poor lubrication, increased component wear, and even equipment failure. Therefore, real-time monitoring of the internal temperature of the crankcase and fault warning have become an important means to ensure the safe operation of the emulsion pump. However, most emulsion pumps in the existing technology are not equipped with a special temperature monitoring structure, and cannot achieve real-time perception and dynamic tracking of the internal temperature of the crankcase.

[0030] As the utility model Figures 1 to 6The device is provided as shown, which comprises a crankcase temperature monitoring device for an emulsion pump, comprising a crankcase 1, a monitoring assembly for monitoring the internal temperature of the crankcase 1 being provided on one side of the crankcase 1, the monitoring assembly comprising a temperature sensor mounted on one side of the crankcase 1, the temperature sensor comprising a temperature sensing rod 8, a lead bobbin 9 and a signal transmitter box 10, a lead bobbin 9 being mounted on one end of the temperature sensing rod 8, a signal transmitter box 10 being mounted on the end of the lead bobbin 9 away from the temperature sensing rod 8, a protective box 4 being fixedly connected to one side of the interior of the crankcase 1, the temperature sensing rod 8 being arranged inside the protective box 4, a heat conducting plate 5 being fixedly connected to an opening on one side of the protective box 4, and the protective box 4 The specifications and dimensions of the opening on one side are adapted to those of the heat conducting plate 5. A heat transfer plate 6 is fixedly connected to one side of the heat conducting plate 5. A fixing cylinder 7 is fixedly connected to the side of the heat transfer plate 6 away from the heat conducting plate 5. A temperature sensing rod 8 is inserted into the interior of the fixing cylinder 7. An inspection component is provided on one side of the crankcase 1. The inspection component is used to protect the lead cylinder 9 and the signal transmitting box 10 while inspecting the temperature sensor. The inspection component is used in conjunction with the monitoring component to protect and position the temperature sensing rod 8, the lead cylinder 9 and the signal transmitting box 10, thereby ensuring stable operation of the temperature sensor and future inspections, thereby achieving durability and maintenance efficiency of the monitoring structure.

[0031] By setting up monitoring components and maintenance components, the combination of the monitoring components and the maintenance components realizes the unity of the accuracy of temperature monitoring of the emulsion pump crankcase 1 and the convenience of operation and maintenance: on the one hand, real-time and accurate monitoring is achieved through the scientific arrangement of temperature sensing conduction paths and signal transmission structures; on the other hand, the sealing protection and quick opening mechanism of the protective box 13 structure ensure the long-term stable operation of the sensing component in a complex environment. The two work together to effectively improve the safety assurance capability and intelligent management level during the operation of the emulsion pump, and have good industrial practical value and promotion prospects.

[0032] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the side of the heat conducting plate 5 away from the heat transfer plate 6 contacts the interior of the crankcase 1. The heat conducting plate 5, the heat transfer plate 6, and the fixing cylinder 7 are all made of stainless steel. A wire barrel 11 is fixedly connected to the top of the signal transmitter box 10 at the end away from the lead barrel 9. A wire conduit 12 is installed on the top of the wire barrel 11. The top of the crankcase 1 is fixedly connected to the equipment box 2, and the end of the wire conduit 12 away from the wire barrel 11 is connected to one side of the equipment box 2.

[0033] Through the provision of the protective box 4, heat conducting plate 5, heat transfer plate 6 and fixed cylinder 7, when the temperature sensing rod 8 senses the temperature, firstly, since one side of the heat conducting plate 5 is in direct contact with the internal space of the crankcase 1, the heat inside the crankcase 1 can be quickly transferred to the heat conducting plate 5; and the heat conducting plate 5, heat transfer plate 6 and fixed cylinder 7 are all made of stainless steel with good thermal conductivity and strong corrosion resistance, which further ensures the efficient conduction of heat in this path. The heat is transferred along the heat conducting plate 5 to the heat transfer plate 6 and enters the interior of the fixed cylinder 7, and then quickly transferred to the temperature sensing rod 8 sleeved in the fixed cylinder 7, realizing real-time response and accurate perception of the actual temperature inside the crankcase 1. At the same time, through the provision of the protective box 4, since the protective box 4 is a space newly set up on the side of the original crankcase 1, it does not affect the movement of the crankshaft inside the crankcase 1, and can ensure that the temperature sensing rod 8 can sense the temperature in real time. Know the temperature. At the same time, the temperature sensing rod 8 is installed through the fixing tube 7. While ensuring the stable position of the temperature sensing rod 8, the stainless steel material of the fixing tube 7 is set to enable heat to be conducted through the fixing tube 7 to the outside of the temperature sensing rod 8 for sensing, which not only avoids interference with data acquisition caused by vibration or displacement, but also enhances the reliability of temperature sensing. In addition, the temperature signal sensed by the temperature sensing rod 8 is transmitted to the signal transmission box 10 through the lead tube 9 connected at one end thereof. The signal transmission box 10 is further connected to the wire tube 12 through the wire tube 11 fixed on the top, and finally the signal is sent to the equipment box 2 located on the top of the crankcase 1, ensuring that the temperature signal is stably and quickly transmitted to the control center, realizing subsequent signal processing, display and alarm functions. The overall structural design not only improves the response speed and accuracy of temperature monitoring, but also enhances the stability and anti-interference ability during signal transmission.

[0034] like Figure 1 、 Figure 2 and Figure 6 As shown, a display screen 24 is installed on one side of the device box 2, an alarm 3 is installed on the top of the device box 2, and a microcontroller and a communication module are installed inside the device box 2. The output end of the signal transmitter box 10 is electrically connected to the input end of the microcontroller through the wire barrel 11 and the wire tube 12, and the output end of the microcontroller is electrically connected to the display screen 24, the alarm 3, and the input end of the communication module;

[0035] Through the set equipment box 2, alarm 3 and display screen 24, the internal temperature of the crankcase 1 is collected in real time through the temperature sensing rod 8, and the detected temperature signal is transmitted to the signal transmission box 10. The signal transmission box 10 processes and converts the signal, converts it into a standard electrical signal that can be recognized by the control system, and transmits it to the microcontroller in the equipment box 2 through the wire pipe 12. The microcontroller analyzes and judges the received temperature signal. When the temperature is within the normal range, the temperature data is displayed in real time through the display screen 24; when the temperature exceeds the set threshold, the alarm 3 is immediately triggered to emit an audible and visual alarm, and the alarm information is uploaded to the remote monitoring system through the communication module, realizing local monitoring and remote linkage monitoring functions to ensure the safe operation of the equipment. It should be noted that when setting the temperature threshold, the set value should be appropriately lowered. This is because the temperature sensing rod 8 is not in direct contact with the air or liquid inside the crankcase 1, but is subjected to temperature sensing through a multi-stage heat conduction path formed by the fixed cylinder 7, the heat transfer plate 6 and the heat conducting plate 5. Although the above structures are all made of stainless steel with good thermal conductivity and are designed to be tightly fitted, in actual operation, in order to avoid heat conduction delay or heat loss, in order to ensure that the temperature alarm signal can be triggered in advance and to ensure the safe operation of the equipment, the temperature threshold needs to be set slightly lower than the actual temperature control requirement value, thereby compensating for the response lag in the heat transfer process, ensuring that the temperature sensing rod 8 can sense the temperature rise in time and trigger an alarm or control action, thereby improving the response speed and reliability of the overall system.

[0036] like Figures 2 to 4 As shown, the side wall of the crankcase 1 is provided with an adapting hole, the diameter of the adapting hole is adapted to the diameter of the temperature sensing rod 8, and the diameter of the lead barrel 9 is larger than the diameter of the adapting hole;

[0037] By setting the adapter hole, when installing the temperature sensing rod 8, it is ensured that only the temperature sensing rod 8 can be inserted into the interior of the fixed tube 7, and at the same time, the lead tube 9 and the signal transmitter box 10 are limited to the outside of the crankcase 1, that is, the inside of the protective box 13, thereby achieving the function of protecting the lead tube 9 and the signal transmitter box 10, and ensuring that the temperature sensing rod 8 can be stably installed inside the fixed tube 7.

[0038] like Figures 1 to 4 As shown, the maintenance assembly includes a protection box 13 fixedly connected to one side of the crankcase 1, the adapter hole is located at the connection between the protection box 13 and the crankcase 1, the lead barrel 9 and the signal transmitter box 10 are located inside the protection box 13, a U-shaped cover 16 is installed on the side of the protection box 13 away from the crankcase 1, the outside of the protection box 13 is fixedly connected to the U-shaped box 14, and a plurality of arc-shaped spring pieces 15 are fixedly connected to both sides of the interior of the U-shaped box 14, respectively. The two ends of the U-shaped cover 16 are respectively inserted between the plurality of arc-shaped spring pieces 15, and when the two ends of the U-shaped cover 16 are inserted into the interior of the U-shaped box 14, one side of the U-shaped cover 16 covers the outside of the protection box 13;

[0039] The U-shaped cover 16 is conveniently opened and closed on the outside of the protective box 13 by the spring clip buckle structure, which can effectively block external dust and foreign matter and facilitate quick maintenance.

[0040] like Figures 1 to 4 As shown, a plurality of heat dissipation grooves are formed on one side of the U-shaped cover 16, and a plurality of dust covers 17 are fixedly connected to one side of the U-shaped cover 16. The dust covers 17 have a trapezoidal shape, and heat dissipation holes are formed on the bottom of the dust covers 17. The positions of the plurality of dust covers 17 correspond to the positions of the plurality of heat dissipation grooves, and the heat dissipation grooves are connected to the heat dissipation holes. A positioning groove 18 is formed on the top of the protective box 13, and the end of the wire barrel 11 away from the signal transmission box 10 passes through the interior of the positioning groove 18.

[0041] By arranging multiple heat dissipation grooves on the U-shaped cover 16 and fixing multiple trapezoidal dust covers 17 with heat dissipation holes on the outside thereof, on the one hand, the heat generated by the signal transmission box 10 inside the protection box 13 can be quickly discharged through the heat dissipation grooves, thereby improving the heat dissipation efficiency of the signal transmission box 10 and avoiding overheating due to long-term operation of internal components; on the other hand, the dust cover 17 effectively covers the outside of the heat dissipation grooves to prevent dust, water vapor or debris from directly entering the protection box 13, ensuring the stable operation of key components such as the signal transmission box 10 and the lead barrel 9, and extending their service life. At the same time, the alignment groove 18 arranged on the top of the protection box 13 is used to limit and guide the wire barrel 11, so that the wire barrel 11 can be accurately positioned when passing through the protection box 13 to avoid deviation or shaking, and at the same time play a role in protecting the wire outlet from wear or distortion, thereby improving the reliability and safety of the entire temperature monitoring structure in a high-intensity working environment.

[0042] like Figures 2 to 4As shown, the top and bottom of the protection box 13 are respectively fixedly connected to the alignment cylinder 21, the internal thread of the alignment cylinder 21 is connected to the screw 22, one end of the screw 22 is fixedly connected to the rotating cap 23, the end of the screw 22 away from the rotating cap 23 passes through the side wall of the protection box 13 and is rotated to clamp the collar 20, and the end of the collar 20 away from the screw 22 is fixedly connected to the C-shaped clip 19. The two C-shaped clips 19 are symmetrically arranged, and the insides of the two C-shaped clips 19 are in contact with the outside of the lead barrel 9;

[0043] By means of the provided screw 22 and C-shaped card 19, when the temperature sensing rod 8 is inserted into the interior of the fixed tube 7, the rotating cap 23 is rotated to cause the screw 22 to move with the C-shaped card 19 toward the outside of the lead tube 9, causing the C-shaped card 19 to contact the outside of the lead tube 9 and be fixed. The threaded adjustment screw 22 and the rotating cap 23 structure are combined with the C-shaped card 19 to firmly clamp the lead tube 9 to prevent loosening and displacement during operation. The overall structure facilitates maintenance personnel to replace and maintain temperature monitoring components, reduces downtime, and improves equipment maintenance efficiency.

[0044] like Figure 2 and Figure 4 As shown, two limiting plates 25 are fixedly connected to the interior of the protection box 13. The corresponding sides of the two limiting plates 25 are in contact with the two sides of the C-shaped card 19 respectively, and are used to limit the C-shaped card 19 to prevent the C-shaped card 19 from rotating or deflecting during the process of fixing the lead barrel 9;

[0045] By providing the collar 20 and the limiting plate 25, the limiting plate 25 can assist in limiting the C-shaped card 19, thereby improving the stability and shock resistance of the device. At the same time, when the screw 22 is rotated, the screw 22 avoids rotating with the C-shaped card 19 through the collar 20, thereby enabling the screw 22 to move up and down stably with the C-shaped card 19, increasing the ease of operation while ensuring the stability of the structure.
