Apparatus for lubricating oil constant temperature heating

Abstract

The invention provides an apparatus for lubricating oil constant temperature heating. The apparatus consists of a reactive circuit, a sleeve (6) and a heater (4) inside the sleeve, wherein a same position of the heater (4) and the sleeve (6) is equipped with a penetrating notch with an edge, and an opening size of the notch is adjusted by a bolt on the edge; provided is a thermoregulator (2), wherein one output terminal is electrically connected with a heater (4) through an adjustable transformer (3) by a cable, and the other output terminal is electrically connected with a thermocouple (5) connecting with the heater through a cable, so as to form the reactive circuit. A structure of the invention is special that oil can be heated to an appropriate temperature by adjusting performance parameters according to actual requirement before lubricating oil detection to reduce oil viscosity, so as to reduce pollution degree distortion caused by large viscosity.

Description

technical field [0001] The invention relates to a heating device, in particular to a device for constant temperature heating of lubricating oil to be tested. Background technique [0002] When testing the pollution degree of lubricating oil, if the lubricating oil is not heated, some problems will arise. For example, when the temperature of the lubricating oil to be tested is low, the lubricating oil has a high viscosity at low temperature. The viscosity of the lubricating oil does not reach the range required by the test instrument, which makes the instrument unable to work normally. On the other hand, it will lead to inaccurate measurement results of the lubricating oil pollution degree detector. In some particle ranges, it may even be an order of magnitude larger, which will lead to Make incorrect decisions and cause unnecessary losses. In order to make the test results more accurate, the lubricating oil needs to be heated before testing to reduce its viscosity. The hea...

AI Technical Summary

Problems solved by technology

The way of direct heating is not suitable for the lubricating oil to be tested for pollution degree, as it will introduce some impurities, which will affect the measurement of the pollution degree of lubricating oil, and this kind of device is bulky, so it can only be used in the laboratory, not as an on-site and online test

Heating by means of a water bath, such as a digital display constant temperature water bath, or a digital display high temperature oil bath oscillator, these devices are relatively large in size and inconvenient to carry, and are only suitable for laboratory use, and the oil reagent bottles are generally plastic products. When heated in a water bath, most reagent bottles will fall or float, and the lid of the reagent bottle is difficult to seal, which will cause the oil to be tested to mix with the medium of the bathtub, and the oil to be tested will be polluted
