Abstract

The invention discloses a novel method and a novel device for detecting the evaporation loss of lubricating oil and provides a flexible heating body for replacing a 'Wood's alloy' heating body mode adopted in the conventional Noack method. The device for detecting the evaporation loss of the lubricating oil adopted in the invention comprises the flexible heating body, a ceramic flat plate heating body, an evaporation boiler, a sealing cover, a sensor inserting device and a temperature sensor, wherein the boiler bottom of the evaporation boiler tightly contacts the ceramic flat plate heating body, a side wall of a shell of the evaporation boiler is wrapped by a layer of the flexible heating body, and the top of the evaporation boiler is provided with the sealing cover; the sealing cover is provided with the sensor inserting device; and the temperature sensor is inserted into or pulled out of the evaporation boiler from the sensor inserting device. The novel method and the novel device solve the problem of pollution generated during the detection, reduce damages to natural environment and human bodies and reduce detection cost.

Description

technical field

[0001] The invention relates to a new method and device for detecting the evaporation loss of lubricating oil. Background technique

[0002] The evaporation of lubricating oil during use will cause the amount of lubricating oil in the lubricating system to gradually decrease, which will eventually affect the oil supply. Therefore, evaporation loss is a very important indicator in the quality inspection of lubricating oil. Lubricating oil manufacturers and research departments must be equipped with this kind of testing equipment to evaluate the quality of oil products.

[0003] At present, the method for detecting the evaporation loss of lubricating oil is: Noack method, in accordance with the "Noack method", in the detection process, a heavy metal "Wood alloy" (Alloy Wood), which contains bismuth, Lead, tin, cadmium and other metals have a low melting point between 60°C and 70°C. The method stipulates that the evaporative dry pan containing the oil sample sh...
