Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a device for detecting water content in lubricating oil. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. In theory, lubricating oil should not contain water. However, no matter in the process of production, processing, transportation, storage, or use, water may enter the lubricating oil. Water has a vital impact on the harm of mechanical equipment, lubrication failure, and oil quality. Water can cause electrochemical corrosion of steel parts, corrosion of mechanical parts, and shorten the service life of the machine; in addition, the generated metal rust ions will promote catalysis together with water and air, so it is necessary to test the water content of the lubricating oil to ensure that it meets the production standards of the lubricating oil.

[0003] However, the existing lubricating oil distillation type water content detection device mixes a certain amount of sample and anhydrous solvent, distills in a specified instrument, and the solvent and water evaporate together and condense in a receiver for continuous separation. Since the density of water is greater than that of the solvent, water is precipitated in the lower part of the receiver, and the solvent returns to the distillation flask for reflux. The ordinary distillation type water content detection device requires more lubricating oil samples for distillation operation because the water reservoir can gather more water flow in the water reservoir to allow the anhydrous volume to reflux. Therefore, the lubricating oil sample is large and more heating energy is required, which is not conducive to small sample detection. Based on this, the utility model designs a lubricating oil water content detection device to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a lubricating oil water content detection device to solve the problem that the ordinary distillation type water content detection device mentioned above requires more lubricating oil samples for distillation operation in the water reservoir so that more water flow can be gathered in the water reservoir to allow the water-free volume to flow back. Therefore, the lubricating oil sample is larger and more heating energy is required, which is not conducive to small sample detection.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for detecting water content in lubricating oil comprises a base plate and a heating cup, a receiving tray is welded to the upper end of the base plate, a support frame is fixedly welded to one side of the base plate, a heating assembly is connected to the upper end of the base plate, a heating cup is placed on the receiving tray, the upper end of the heating cup is open, an inclined liquid inlet pipe is connected to one side of the heating cup, the upper opening of the heating cup is connected to an air duct through a sealing plug, a condenser and a water collector are connected to the upper end of the support frame in descending height, the air duct runs through the condenser, the air duct is connected to the upper end of the water collector through a sealing plug, the bottom of the water collector is an open end, a sealing piston is connected to the bottom end of the water collector, a pull rod is connected to the middle of the sealing piston, a reflux pipe is connected to the upper end of the water collector, and the tail end of the reflux pipe is sealed and stuck in the liquid inlet pipe.
