Technical Field

[0001] The utility model relates to the technical field of lubricating oil, in particular to an automatic detection instrument for the moisture content of lubricating grease. Background Technique

[0002] Lubricating oil is a liquid lubricant used to reduce friction and wear of mechanical equipment. Moisture in the lubricating oil will cause it to emulsify, and the lubricating performance of the emulsified lubricating oil will be significantly reduced, and it cannot effectively protect mechanical equipment. Therefore, detecting and controlling the moisture in the lubricating oil is a key step to ensure its quality.

[0003] When detecting the moisture content of lubricating oil, a detection instrument is required. During the use of the existing detection instrument, the lubricating oil is usually sampled for detection, and the detection instrument cannot be directly connected inside the lubricating oil barrel for detection. The sample will directly affect the final detection result and the detection accuracy. Moreover, when the moisture content in the lubricating oil exceeds the standard, it is necessary to separate the oil and water, and the moisture in the lubricating oil cannot be directly removed, which affects the use efficiency of the lubricating oil.

[0004] Therefore, it is necessary to provide a new automatic detection instrument for the moisture content of lubricating grease to solve the above technical problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 As shown, an automatic lubricating grease moisture detection instrument includes a base 1. A support frame 2 is fixed on the top of the base 1. A digital display meter body 3 is arranged on one side of the support frame 2. An installation frame 4 is fixedly connected to the outside of the digital display meter body 3. A clamping block 5 is clamped on the inner wall of the installation frame 4. A damper 6 is fixedly connected to the outside of the digital display meter body 3. A protective plate 7 is fixedly connected to one side of the damper 6. The damper 6 and the protective plate 7 are used to protect the digital display meter body 3. A storage oil barrel 8 is arranged on the top of the base 1 to store lubricating oil. A connecting wire 9 is arranged at the bottom of the digital display meter body 3. A resistance sensor 10 is arranged at the bottom of the connecting wire 9. The resistance sensor 10 can be used to detect the moisture in the lubricating oil. A generator 26 is arranged on the top of the base 1 to generate low-voltage electricity. Once the low-voltage electricity is conducted, it indicates that there is moisture in the oil. A support seat 11 is fixedly connected to the bottom of the storage oil barrel 8. A support plate 12 is fixedly connected to the inner wall of the support seat 11. A heating rod 13 is arranged on the top of the support plate 12 to heat the moisture inside the storage oil barrel 8 to evaporate the moisture and process the excess moisture.

[0024] A first spring 14 is fixedly connected to the inner wall of the support frame 2. One end of the first spring 14 is fixedly connected to a connecting block 15. The outside of the connecting block 15 is slidably connected to the inner wall of the support frame 2. One side of the connecting block 15 is fixedly connected to one side of the clamping block 5. Pressing the clamping block 5 drives the connecting block 15 to slide inside the support frame 2, causing the first spring 14 to contract. The installation frame 4 is installed on the outside of the support frame 2. The first spring 14 resets to drive the connecting block 15 and the clamping block 5 to reset, so that the clamping block 5 is clamped with the inner wall of the installation frame 4, thereby installing the digital display meter body 3. A fixed seat 16 is fixedly connected to the outside of the digital display meter body 3. A sliding rod 17 is slidably connected to the inner wall of the fixed seat 16. A second spring 18 is arranged on the outside of the sliding rod 17. One end of the sliding rod 17 is fixedly connected to a connecting plate 19. One side of the connecting plate 19 is fixedly connected to one side of the protective plate 7. When the digital display meter body 3 is collided, it drives the protective plate 7 to move, causing the connecting plate 19 to drive the sliding rod 17 to slide inside the fixed seat 16, causing the second spring 18 to contract. Through the action of the second spring 18 and the damper 6, the protective plate 7 quickly resets, reducing the impact force received by the digital display meter body 3 and protecting the digital display meter body 3.

[0025] A mounting block 20 is fixedly connected to the top of the oil storage barrel 8, and a liquid level sensor 21 is arranged on the top of the mounting block 20. The liquid level inside the oil storage barrel 8 is monitored by the liquid level sensor 21. An inlet 22 and a drain pipe 23 are respectively arranged on the outer side of the support seat 11. A valve is arranged on the outer side of the drain pipe 23. Water is injected into the support seat 11 through the inlet 22, and the water flow is heated by the heating rod 13, so as to heat the lubricating oil inside the oil storage barrel 8, evaporate the water in the lubricating oil, and thus remove the excessive water. A protective cover 24 is arranged on the outer side of the digital display meter body 3, and an alarm 25 is arranged on the top of the support frame 2.

[0026] Working principle: When the device is in use, pressing the clamping block 5 drives the connecting block 15 to slide inside the support frame 2, so that the first spring 14 contracts. The mounting frame 4 is installed on the outer side of the support frame 2. The first spring 14 resets to drive the connecting block 15 and the clamping block 5 to reset, so that the clamping block 5 is clamped with the inner wall of the mounting frame 4, thereby installing the digital display meter body 3. When the digital display meter body 3 is collided, it drives the protective plate 7 to move, so that the connecting plate 19 drives the sliding rod 17 to slide inside the fixed seat 16, so that the second spring 18 contracts. Through the action of the second spring 18 and the damper 6, the protective plate 7 quickly resets, reducing the impact force on the digital display meter body 3 and protecting the digital display meter body 3. The generator 26 generates low-voltage electricity. Once the low-voltage electricity is conducted, it means that there is water in the oil. The direct-current high voltage generated by the DC / DC conversion of the generator 26 as the power supply exits from the E pole, passes through the test product, and reaches the L pole, thereby generating a current from the E pole to the L pole. After passing through the I / V conversion and completing the operation by the divider, the resistance change of the lubricating oil is monitored by the resistance sensor 10 and displayed by the digital display meter body 3, so as to achieve the effect of detecting the water in the lubricating oil. Water is injected into the support seat 11 through the inlet 22, and the water flow is heated by the heating rod 13, so as to heat the lubricating oil inside the oil storage barrel 8, evaporate the water in the lubricating oil, and thus remove the excessive water.
