Description

Technical Field

[0001] The utility model relates to an oil online monitoring device, specifically, the utility model relates to a mounting bracket for the oil online monitoring device, especially, the utility model relates to a mounting bracket for the lubricating oil return pipeline online monitoring device. Technical Background

[0002] Lubricating oil is widely used in the metallurgical industry. However, due to the harsh metallurgical environment, water and mechanical impurities are often mixed into the used lubricating oil, affecting the performance of the lubricating oil and causing poor lubrication, which directly affects the performance and life of the mechanical device.

[0003] Oil moisture sensors are commonly used to monitor trace moisture in hydraulic systems, lubrication systems, and power transformers. These sensors can continuously, accurately, and quickly measure water activity, trace moisture content, and temperature in oil even in harsh environments. They are particularly suitable for monitoring water molecules in industrial oils, particularly transformer oil and lubricating oils. The main functions of oil moisture sensors include measuring both trace moisture (unsaturated water content) and free water content (free water mixed in the oil). This ensures that oil quality is protected from emulsification caused by water intrusion, which could affect the proper operation of machinery and equipment or even cause serious accidents. Therefore, monitoring trace moisture in lubricating oil is of paramount importance.

[0004] Furthermore, moisture can cause bearing corrosion, and water mixed with oil can also affect oil performance and reduce its viscosity. Therefore, excessive moisture and contamination of thin oil lubricants with other debris can seriously compromise the proper functioning of thin oil lubrication systems. According to relevant data, system failures caused by lubricant contamination currently account for approximately 65% ​​of all thin oil lubrication system failures. The issue of water content in lubricants has garnered widespread attention.

[0005] The commonly used method at present is to install a water content sensor in the lubricating oil pipeline to monitor the changes in the water content of the oil. However, when the sensor is installed on the surface of the pipeline or on a bracket deep inside the pipeline, impurities in the lubricating oil often adhere to the sensor probe, resulting in inaccurate monitoring data. Therefore, the sensor needs to be cleaned and calibrated regularly. However, when cleaning the sensor, the lubrication system needs to be stopped, and it takes a long time for the lubricating oil to flow back to the oil tank to prevent the lubricating oil from spraying out from the sensor installation position, which inevitably affects production efficiency. At the same time, some oil will leak out when the sensor is disassembled, which not only pollutes the environment but also makes cleaning more inconvenient. The above are the main problems encountered when maintaining sensors in the oil online monitoring system in this scenario, which has led to the slow application and promotion of the current oil online monitoring technology. Utility Model Content

[0006] In order to solve the above problems, the purpose of the present utility model is to provide a mounting bracket for an online oil monitoring device, and in particular, to provide a mounting bracket for an online lubricating oil return pipeline monitoring device. The mounting bracket for the online lubricating oil return pipeline monitoring device remains sealed and can be quickly disassembled. The sensor can perform online monitoring without stopping the operation of the lubrication system and without causing oil leakage, and the sensor can be quickly replaced / maintained.

[0007] The technical solution of this utility model is as follows:

[0008] An installation bracket for an oil online monitoring device is used for online monitoring of pipeline oil and quick replacement / maintenance of the oil online monitoring device.

[0009] It is characterized by:

[0010] The mounting bracket for the oil online monitoring device includes:

[0011] Sleeve 1: One end is the oil pipeline installation end, fixed on the oil pipeline;

[0012] The other end is the monitoring end of the online monitoring device, which is provided with a piston assembly and the online monitoring device connected thereto;

[0013] A piston cylinder is formed between the two ends of the sleeve 1, which provides a moving space for the piston assembly and the online monitoring device connected thereto, ensuring that the piston assembly performs reciprocating linear motion along the axis of the sleeve cylinder body;

[0014] The oil pipeline mounting end of the sleeve 1 is connected to the oil pipeline through the sleeve mounting flange 1-1 fixedly connected to the mounting end and the pipeline mounting flange 12.

[0015] A third flange 2 is provided outside the sleeve mounting flange 1-1, and a piston pulling rod 4 that can be manually pulled in and out is fixedly connected to the first piston disc 7-1 and the third flange 2;

[0016] The piston assembly 7 includes: a first piston disc 7-1 and a second piston disc 7-5, each equipped with an O-ring 7-2, and the first piston disc 7-1 and the second piston disc 7-5 are fixedly connected by a connecting rod 7-3;

[0017] The monitoring end of the sleeve 1 is fixed on the first piston disc 7-1 through a threaded connection. The internal online monitoring device can move along the axial direction of the sleeve through the action of the piston assembly 7 and the piston pulling rod 4 until the detection probe of the online monitoring device moves into the pipeline oil outside the monitoring end of the sleeve, and is fixed to the sleeve mounting flange 1-1 through the third flange 2 to keep it stable in the oil pipeline and detect the pipeline oil; when the piston assembly 7 moves outward to the baffle 3, the online monitoring device can be disassembled, cleaned or replaced.

[0018] According to the present invention, the third flange 2 is manually pulled to move the piston assembly 7. The length of the pull rod is currently not adjustable and is determined according to the location of the on-site installation pipeline. The purpose is to extend the sensor detection element (probe) 11 on the piston disc 7-1 into the oil.

[0019] The piston assembly 7 and the piston pull rod 4 are used to enable the detection probe of the online monitoring device to move axially along the piston cylinder. When it moves to the pipeline oil outside the monitoring end of the sleeve, the pipeline oil can be detected and the monitoring device can be fixed; when it moves to the installation end of the sleeve, it can be used to disassemble, clean or replace the online monitoring device.

[0020] According to the mounting bracket for an oil online monitoring device of the utility model, the feature is that the distance between the two piston discs is larger than the size of the detection element probe of the online monitoring device for the oil entering the pipeline.

[0021] That is, the distance between the two piston discs is determined according to the size of the detection element probe of the online monitoring device that needs to enter the pipeline oil.

[0022] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0023] Three piston connecting rods 7-3 are provided, and the mounting bracket is provided with a 60-100 mesh filter 7-4 covering the outer periphery of the piston connecting rod 7-3 and used to prevent impurities in the oil from adhering to the detection element probe.

[0024] This prevents impurities in the oil from adhering to the detection element and affecting the detection accuracy.

[0025] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0026] A baffle 3 is provided between the sleeve mounting flange 1-1 and the third flange 2. The baffle 3 is connected to the sleeve mounting flange 1-1 by fastening bolts and is provided on the outer side of the sleeve mounting flange 1-1.

[0027] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0028] The inner diameter of the baffle 3 is smaller than the inner diameter of the sleeve cylinder, that is, the diameter of the piston cylinder or the outer diameter of the piston assembly.

[0029] Thus, it is used to prevent the piston assembly 7 from being pulled out of the cylinder body in the sleeve 1 when the piston assembly 7 is pulled out. In this way, during the process of pulling the piston assembly 7, the piston assembly 7 will be blocked by the baffle and cannot be pulled out of the sleeve cylinder body, thereby avoiding leakage of oil.

[0030] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0031] A positioning hole 10 is opened on the inner periphery of the baffle 3, and a positioning bolt 6 is installed on the outer surface of the first piston disc 7-1. When the piston assembly 7 is pulled out, the third flange 2 is rotated so that the positioning bolt 6 set on the outer surface of the first piston disc 7-1 is embedded in the positioning hole 10.

[0032] See Figure 3B At position 10, the positioning bolt 6 provided on the outer surface of the piston disc is embedded in the positioning hole 10, which plays a radial positioning function when disassembling the sensor. At the same time, it can transmit the torque to the sleeve and the installation pipeline to prevent the piston pull rod from being deformed due to excessive torque.

[0033] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0034] A piston connecting rod 7-3 is provided between the first piston disc 7-1 and the second piston disc 7-5 to fix the two piston discs, and a 60-100 mesh filter 7-4 is provided outside to wrap the outer periphery of the piston connecting rod 7-3.

[0035] This prevents impurities in the oil from entering the sensor monitoring hole and causing the monitoring data to become invalid.

[0036] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0037] A baffle 3 is provided between the sleeve mounting flange 1 - 1 and the third flange 2 . The baffle 3 is connected to the sleeve mounting flange 1 - 1 by fastening bolts and is provided on the outer side of the sleeve mounting flange 1 - 1 and the inner side of the third flange 2 .

[0038] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0039] During installation, the axis of the oil online monitoring device is set perpendicular to the axis of the oil pipeline.

[0040] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0041] The oil is lubricating oil or hydraulic oil, and the oil online monitoring device is an online sensor.

[0042] The utility model can also be applied to other oil measurement scenarios.

[0043] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0044] The third flange 2 and the baffle 3 are both hollow, which is convenient for the sensor cable to be routed out.

[0045] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0046] During installation, the axis of the oil online monitoring device is set perpendicular to the axis of the oil pipeline.

[0047] According to the mounting bracket for an oil online monitoring device of the utility model, it is characterized in that:

[0048] The piston pull rod 4 used to connect the piston assembly and the third flange 2-1 at the mounting end is connected by a threaded end at one end and a reamed hole at the other end.

[0049] Therefore, after the third flange 2 pulls out the piston assembly 7, the piston pulling rod 4 can be removed from the first piston disc 7-1 by removing the hinged hole end nut, providing sufficient space for disassembly of the sensor.

[0050] Beneficial effects:

[0051] The mounting bracket for an online oil monitoring device disclosed in this utility model facilitates online oil monitoring and allows for quick replacement / maintenance of the monitoring device, preventing oil leaks during operation without interrupting oil flow or causing downtime, thereby improving production efficiency. Furthermore, the bracket features a simple structure, strong independence, low cost, and easy maintenance. It can significantly expand the application of online oil monitoring and enhance the digitalization and intelligence of lubrication systems. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0062] Example

[0063] A mounting bracket for an online oil monitoring device, specifically a mounting bracket for an online water content monitoring device for a lubricating oil return pipeline. The lubricating oil return pipeline online water content monitoring device is a water content sensor mounting bracket that maintains sealing and can be quickly disassembled.

[0064] like Figure 4 , Figure 6 shows how the device is installed in the pipeline.

[0065] The mounting bracket for the lubricating oil return pipeline online water content monitoring device includes:

[0066] A water content sensor is installed inside and a sleeve 1 is extended into the oil return pipe. The sleeve 1 is welded by a piston cylinder and a mounting flange. The piston cylinder provides a moving space for the piston assembly and plays a role in axial movement guidance.

[0067] The mounting end of the sleeve 1 is connected to the pipeline mounting flange (disc) 12 through the flange 1-1 and fixed to the oil pipeline.

[0068] The monitoring end of the sleeve 1 is provided with a piston assembly which can move inside and outside the sleeve along the axial direction of the sleeve:

[0069] The piston assembly includes: first piston discs 7-1 and 7-5, each equipped with an O-ring. The monitoring end of the sleeve 1 is fixed to the first piston disc 7-1 through a threaded connection. The internal online monitoring device can be moved along the axial direction of the sleeve to the lubricating oil pipeline outside the monitoring end of the sleeve through the action of the piston assembly 7 or the piston pull rod 4. The online monitoring device remains stable in the oil pipeline.

[0070] The piston assembly 7 and the piston pulling rod 4 are used for fixing, disassembling, cleaning or replacing the online monitoring device.

[0071] During normal operation, sleeve 1 extends into the branch pipe and is secured to the pipeline via pipe flange 12. The interior of sleeve 1 acts as a guide for the axial movement of piston assembly 7 (see Figure 2). Water content sensor probe 11 is placed in the pipeline oil. Third flange 2 is screwed to sleeve mounting flange 1-1 and connected to piston assembly 7 via pull rod 4, ensuring sensor 5 remains stable in the oil pipeline.

[0072] The baffle 3 is located between the third flange 2 and the sleeve mounting flange 1-1, and is used to prevent the piston assembly 7 from escaping from the sleeve 1 when it is pulled out. There are positioning holes on the outer periphery of the baffle 3. By rotating the third flange 2, the positioning bolts 6 installed on the outer surface of the first piston disc 7-1 are embedded in the positioning holes 10 on the inner periphery of the baffle 3, which plays a radial positioning function when disassembling the sensor (see Figure 3).

[0073] In this embodiment, the third flange 2 and the baffle 3 are both hollow, which facilitates the outlet of the sensor cable.

[0074] Three pull rods 4 connect the first piston disc 7-1 and the third flange 2. This connection allows ample space for tools to remove the sensor. The moisture sensor 5 is threadedly secured to the first piston disc 7-1 and features a hexagonal head for easy removal and replacement.

[0075] The piston assembly 7 consists of five parts. 7-1 and 7-5 are piston discs, each fitted with an O-ring 7-2 for sealing. This ensures a tight seal both when the piston assembly 7 is moving axially and when stationary. There are three connecting rods 7-3, each connecting the first and second piston discs 7-1 and 7-5. A filter 7-4, with a mesh size of 60-100, wraps around the outside of the connecting rods 7-3 to prevent oil impurities from entering the sensor probe. The filter 7-4 should be replaced regularly.

[0076] When the sensor needs to be replaced / maintained, remove the fastening bolts 8 on the third flange 2, pull the third flange 2 outward so that the first piston disc 7-1 reaches the position of the baffle 3, and at the same time rotate the third flange 2 so that the positioning bolts 6 are aligned with the positioning holes 10 at the inner hole of the baffle 3, forming a radial restriction function to prevent the piston assembly 7 from rotating circumferentially when the sensor is removed, as shown in Figure 3.

[0077] At this point, the sensor has exited the oil pipeline, and the second piston disc 7-5 remains sealed, isolating the oil from the external environment, and the pipeline oil can still operate normally. Use a wrench to align the sensor hexagonal head structure to easily remove the sensor.

[0078] The interior of sleeve 1 guides the axial movement of piston assembly 7 (see Figure 2). The water content sensor probe 5 is placed in the pipeline oil. Third flange 2 is connected to sleeve mounting flange 1-1 via fastening bolts 8 and connected to piston assembly 7 via pull rod 4, ensuring the stability of sensor 5 in the oil return line. Baffle 3, located between third flange 2 and sleeve mounting flange 1-1, prevents piston assembly 7 from escaping from sleeve 1 when withdrawn.

[0079] The outer surface of baffle 3 has positioning holes. By rotating the third flange 2, the positioning bolts 6 installed on the outer surface of the first piston disk 7-1 are inserted into the positioning holes 10 on the inner periphery of the baffle 3, providing radial positioning for sensor removal (see Figure 3). The third flange 2 and baffle 3 are both hollow to facilitate the sensor cable outlet.

[0080] When the filter 7-4 needs to be replaced, the fixing bolts 9 on the baffle 3 need to be removed to disengage the baffle 3 from the sleeve mounting flange 1-1, allowing the piston assembly 7 to be further withdrawn. When the filter 7-4 is exposed from the sleeve mounting flange 1-1, it is removed from the connecting rod 7-3 and replaced. During this replacement operation, a dedicated person must hold the third flange 2 and ensure that the piston head 7-5 is inside the sleeve 1 to prevent the lubricating oil in the pipeline from leaking out abnormally.

[0081] According to the utility model, a mounting bracket for an online water content monitoring device for a lubricating oil return pipeline can be kept sealed during operation and can be quickly disassembled. The sensor can perform online monitoring without stopping the operation of the lubrication system and without generating oil leakage, and the sensor can be quickly replaced / maintained.
