Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil detection, in particular to a detector for quickly detecting solidification point. Background Art

[0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction, protect machinery and processing. It is generally composed of two parts: base oil and additives. Its main function is to reduce friction and wear, cool down, prevent rust and corrosion, etc. It can extend the service life of the machinery and improve the working efficiency and reliability of the machinery.

[0003] The freezing point test is a test method used to determine the temperature at which a liquid sample begins to solidify and lose fluidity under specific conditions. Usually, the temperature of the sample is gradually lowered according to the surface operating procedures, and the state changes of the sample are observed. When visible crystals appear in the sample or the sample loses fluidity, the corresponding temperature at this time is the freezing point of the sample. In order to ensure that the lubricating oil can still maintain good fluidity in the low temperature environment where the equipment is running, and to avoid normal lubrication due to solidification, its performance is usually tested through this test.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1.

Temperature fluctuations may affect the test results of the lubricating oil sample; 2.

[0036] The use method and advantages of the utility model: When the detector for rapid detection of freezing point is used, the working process is as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, firstly, the external pipe port 107 on one side of the detection box 1 is connected to the external refrigeration equipment through a pipeline, the sample to be detected is placed in the interior of the reagent bottle 4, and the bottle cap 401 is inserted into the groove on the top of the reagent bottle 4, and at the same time, one end of the buckle 404 is pulled to install it with the block 402 through the snap-fit ​​connection structure, and the buckle 404 applies a certain pressure to the block 402 when fixing the block 402 due to the elastic structure of the spring 403, so that the bottle cap 401 is more tightly connected to the reagent bottle 4, and it is pulled upward through the handle on the surface of the box cover 103, and the first connecting rod 101 and the second connecting rod 102 are stretched from the original horizontal distribution on the inner wall of the detection box 1 as the box cover 103 is lifted and are vertically distributed between the detection box 1 and the box cover 103. Then, the box cover 103 is then parallel to one end above the detection box 1. The operator can place the bottom of the reagent bottle 4 on the arc-shaped lower base 301, pull one side of the arc-shaped upper top seat 302, slide and pull out the end located inside the arc-shaped lower base 301, and thread the corresponding threaded holes of the two with the limit bolt 304, and move it downward again through the handle on the surface of the box cover 103. During the movement, the first connecting rod 101 and the second connecting rod 102 rotate and retract and fold to the chain side of the inner wall of the detection box 1, and one end of the first tension spring 104 rotates accordingly with the rotation of the second connecting rod 102. When the box cover 103 is closed on the top of the detection box 1, the metal sheet 10 on the top thereof 6 is correspondingly inserted into the groove where the magnetic stone 105 is located on the top of the detection box 1 and is magnetically connected to it. After the power is turned on, cold air is continuously discharged into the interior of the detection box 1 through the external refrigeration device through the external pipe port 107. At the same time, the output end of the stepper motor 203 drives the driving gear 201 to rotate, so that the driven gear 202 drives the clamping component 3 clamping the reagent bottle 4 to rotate. The use of the rotating structure can effectively promote the uniform mixing of various components in the medium, ensure the uniform distribution of additives and impurities in the sample, improve the representativeness and accuracy of the detection, thereby shortening the time of the entire detection process, and the dynamic rotation can more accurately simulate the actual use of lubricating oil in equipment or machinery. The internal temperature sensor 405 (model wzp-p t100) and viscosity sensor 406 (model WKC1204) respectively adopt wireless structure to facilitate the rotation detection of samples, and respectively connect to external control system through Bluetooth module to react to the characteristics of medium in real time. During the detection process, the operator can observe through the visual window on the surface of detection box 1, and when the pressure value inside detection box 1 is too low, the pressure relief pipe 502 can be connected to the external air pump, and the stop valve on the surface of pressure inlet pipe 501 can be opened to provide pressure to the detection box 1. When the pressure value inside detection box 1 is too high, on the contrary, the stop valve of pressure inlet pipe 501 is opened to discharge the excess pressure into pressure relief box 5, and according to the value of second pressure detection gauge 503, the excess pressure is selectively released through pressure relief pipe 502.
