Description

TECHNICAL FIELD

[0001] The utility model relates to the field of petroleum equipment manufacturing, and specifically relates to a rotating disc full heating mechanism for special oil product viscosity measurement. BACKGROUND

[0002] In modern industry and daily life, lubricants are widely used, and they play a crucial role in ensuring the normal operation of mechanical equipment. Lubricants are not limited to petroleum products such as engine oil and gear oil, but also include some non-petroleum derivatives such as synthetic base oil and certain vegetable oils. These substances are widely used to reduce friction, prevent wear and tear, and transmit power due to their unique viscosity and chemical properties. The normal operation of equipment often depends on the appropriate viscosity of the lubricant used. Too high or too low viscosity can adversely affect the performance of the equipment. For example, lubricants with too low viscosity may not form an effective protective film between equipment components, leading to increased wear and tear; while lubricants with too high viscosity will increase friction, reduce equipment efficiency, and even cause overheating.

[0003] In addition, the viscosity of petroleum fuels is also important for optimizing storage, operation, and operating conditions. The viscosity of fuel affects its flow characteristics in pipelines, which in turn affects the efficiency of transportation and energy consumption. In cold weather conditions, high fuel viscosity can cause pipeline blockage, affecting the continuity of supply. Therefore, precise control of fuel viscosity is crucial to ensure the stable operation of energy systems. In the oil industry, viscosity management is a complex process that involves comprehensive consideration of various factors, including temperature, pressure, and the chemical composition of the fuel.

[0004] However, current domestic automatic kinematic viscosity instruments generally lack automatic devices when dealing with preheated oil samples. This means that before performing viscosity measurement, the operator must manually preheat the sample, which not only consumes time and effort, but also may affect the accuracy of the measurement due to improper temperature control. In order to improve efficiency and measurement accuracy, it is particularly important to develop a viscosity measurement instrument with automatic preheating function. SUMMARY

[0005] The utility model aims at providing a rotating disc full heating mechanism for special oil product viscosity measurement.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0007] A rotating disc full heating mechanism for special oil product viscosity measurement, comprising:

[0008] A drive shaft is provided with an inner ring conductive slip ring and an outer ring conductive slip ring on the drive shaft;

[0009] A rotating disc is provided on the drive shaft;

[0010] A heating plate is arranged on the inner side of the rotating disc and closely arranged on the inner side of the rotating disc;

[0012] A rotating disc heat preservation layer is arranged on the surface of the rotating disc except the sample groove;

[0013] A heating plate heat preservation layer is arranged at the lower end of the heating plate;

[0014] A temperature sensor is inserted into the rotating disc to transmit the real-time temperature of the rotating disc through heat-conducting silicone grease,

[0016] A temperature protection switch is inserted into the rotating disc to monitor the real-time temperature of the rotating disc through heat-conducting silicone grease, and the lead wire of the temperature protection switch is connected with the lead wire of the inner ring conductive slip ring;

[0017] The lead wire of the outer ring conductive slip ring is connected with the main machine of the instrument;

[0018] The inner ring conductive slip ring and the outer ring conductive slip ring rotate relative to each other, so that the lead wire of the outer ring conductive slip ring does not rotate with the inner ring conductive slip ring when the rotating disc rotates.

[0019] In one preferred embodiment of the present application, the outer side of the heating plate is in contact with the inner side of the rotating disc through heat-conducting silicone grease.

[0020] In one preferred embodiment of the present application, the inner ring conductive slip ring and the driving rotating shaft are fixed together through a locking screw.

[0021] In one preferred embodiment of the present application, the end of the driving rotating shaft is provided with a handle.

[0022] In one preferred embodiment of the present application, the rotating disc heat preservation layer comprises an upper rotating disc heat preservation layer and a lower rotating disc heat preservation layer for cooperating with the rotating disc.

[0023] In one preferred embodiment of the present application, the temperature sensor is a PT100 temperature sensor.

[0024] The present application mainly provides a full heating mechanism capable of preheating a sample to be tested and preserving heat during the test, and the mechanism of the present application can provide a full-automatic viscosity testing instrument for special samples requiring preheating in combination with the automatic testing structure of the existing instrument.

[0025] Users only need to place the sample to be tested into the sample test hole (24-bit) to automate the entire process of sample preheating, testing, cleaning and drying. Attached Figure Description

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following descriptions, well-known structures and technologies have been omitted to avoid unnecessary confusion regarding the concept of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figure 1 The illustrated rotary heating mechanism for measuring the viscosity of special oils includes a drive shaft 1, on which an inner conductive slip ring 2 and an outer conductive slip ring 3 are mounted. The inner conductive slip ring 2 and the outer conductive slip ring 3 rotate relative to each other. The inner conductive slip ring 2 is fixed to the drive shaft 1 by a set screw. A handle 11 is provided at the end of the drive shaft 1 for easy disassembly.

[0030] The turntable 4 is mounted on the drive shaft 1. A heating plate 5 is mounted on the inner side of the turntable 4. The heating plate 5 is mounted close to the inner side of the turntable 4. The outer side of the heating plate 5 is in contact with the inner side of the turntable 4 through thermal grease.

[0031] The turntable 4 has a sample slot 41 for placing samples. A turntable insulation layer 6 is provided on the surface of the turntable 4, excluding the sample slot 41. The turntable insulation layer 6 includes an upper turntable insulation layer 61 and a lower turntable insulation layer 62 that wrap around the turntable 4 for insulation. The upper turntable insulation layer 61, the lower turntable insulation layer 62, and the heating plate insulation layer 7 together wrap the turntable 4 and the heating plate 5 to prevent heat loss. A decorative panel 63 can also be provided outside the upper turntable insulation layer 61 as needed.

[0032] The temperature sensor 8 is inserted into the rotary disc 4 and transmits the real-time temperature of the rotary disc 4 through the heat-conducting silicone grease.

[0034] The wire of the outer circle conductive slip ring 3 is connected with the existing instrument host (not shown in the figure), the inner circle conductive slip ring 2 rotates relative to the outer circle conductive slip ring 3, so that the wire of the outer circle conductive slip ring 3 does not rotate with the inner circle conductive slip ring 2 when the rotary disc 4 rotates, thereby avoiding winding.

[0035] As shown in the figure, the real-time temperature of the rotary disc is transmitted to the instrument control system through the conductive slip ring, the rotary disc does not affect the instrument to heat the rotary disc when rotating, and the purpose of accurately controlling the temperature of the rotary disc is achieved through heat preservation.
