Description

Technical Field

[0001] The utility model belongs to the technical field of lubricating grease oil separation determination, and specifically relates to a novel lubricating grease cone-net oil separation experimental device. Background Art

[0002] Grease is a solid lubricant made from a thickener, base oil, and additives. It is widely used in automobiles, aircraft, and various mechanical transmission mechanisms, performing multiple functions such as lubrication, sealing, and protection. Grease oil separation refers to the separation of base oil from grease under certain temperature and pressure conditions. This indicator reflects the colloidal stability of the grease and is a key parameter in characterizing its stability.

[0003] Existing grease oil separation testing equipment primarily consists of a thermostat and a steel mesh oil separation tester. The thermostat provides the required constant temperature. The steel mesh oil separation tester consists of a conical mesh made of 248μm corrosion-resistant wire, a 200mL tall, spoutless beaker, and a lid that fits snugly into the beaker and features a hook at the center of the lid's base. The experimental procedure is as follows: A weighed, qualified steel mesh oil separation tester filled with grease is placed in the thermostat for testing. After the test is complete, the tester is removed from the thermostat and allowed to cool to room temperature. The lid is then removed from the beaker and gently tapped to allow the oil on the tip of the conical mesh to drip down the beaker wall, preventing any residual oil from the tip.

[0004] However, the grease oil separation experimental equipment in the prior art has the following problems: (1) The temperature control accuracy is not up to standard: The thermostats currently on the market generally adopt the design principle of stirring the heat after heating the heating element; due to the limitations of the temperature control meter, heating wire, stirring motor, etc., it is difficult to maintain a constant temperature field with an accuracy requirement of ±0.5°C; this leads to inconsistent cone net test results at different positions in the same thermostat, affecting the comparison of results between different laboratories and causing experimental errors. (2) The operation process is cumbersome and unsafe: This is mainly due to the fact that the operation process involves relatively more manual work by the laboratory technician, which leads to unsafe conditions. After the thermostat reaches 100°C, the laboratory technician needs to manually open the thermostat door and place the cone net oil separation assembly into the thermostat; at this time, the inside of the box, the door, the bracket, etc. are all in a high temperature state of about 100°C, which can easily cause burns to the laboratory technician; similarly, when removing the cone net oil separation assembly after the experiment, there is also a risk of burns from hot air or high-temperature parts.

[0005] In summary, the existing grease oil separation experimental equipment has obvious deficiencies in temperature control accuracy and operational safety. Therefore, a new type of grease cone mesh oil separation experimental equipment is urgently needed to solve these problems in order to improve the temperature control accuracy and operational safety of the experiment.
