The method and the device have the advantages of simple operation method, high heating speed, uniform temperature, good sealing and heat preservation effect, accurate testing result, and the like.
Description
Technical field
The present invention relates to a kind of method and the device that detect lubricating oil evaporation loss, existing assay method and device can be substituted completely.
Background technology
Lubricating oil evaporation in use, can cause lubricants capacity in lubricating system to reduce gradually, finally affect fuel feeding.So vaporization loss is index very important in lubricating oil product quality detection, OIL IN LUBRICATING OIL PRODUCTION producer and research department must be equipped with this kind of detecting instrument, in order to evaluate oil quality.
At present, the device detecting lubricating oil evaporation loss is: at the bottom of a pan and the earthenware slab calandria close contact of the dry pot of evaporation, the side wall of outer shell evaporating dry pot wraps up the flexible calandria of one deck, the top of evaporating dry pot is provided with a gland bonnet, gland bonnet is provided with a sensor docking apparatus, and temperature sensor inserts the dry pot inside of evaporation from sensor docking apparatus or extracts.This pick-up unit also exists calandria and installs trouble, and method complicated operation, easily scalds operator; Evaporate the shortcomings such as lubricating oil temperature in dry pot is uneven.
Summary of the invention
Before overcoming, detect the method for lubricating oil evaporation loss and the shortcoming of device, improve measuring accuracy further, improve working environment, the invention provides a kind of lubricating oil evaporation loss method for measuring and device.
Detect a method for lubricating oil evaporation loss, concrete steps are:
A. by the test oil sample stirring magnetic bar and weigh, put into the dry pot of evaporation, encryption is sealed up lid and is regulated corresponding vacuum tightness, cut-in temperature sensor;
B. more dry for evaporation pot is put into high-frequency electromagnetic cartridge heater;
C. beginning is tested, open high-frequency electromagnetic cartridge heater to test oil sample Fast Heating, open drive motor makes driving magnetic bar drive stirring magnetic bar to stir oil sample in the dry pot of evaporation simultaneously, ensures to reach 245.2 ± 0.5 DEG C in the corresponding time, observes the oil sample evaporation capacity in the dry pot of evaporation;
D. after test terminates, by auxiliary cooling system and heat abstractor, make evaporation do pot and lower the temperature rapidly, to reach or close to room temperature.
A kind of device detecting lubricating oil evaporation loss, formed by the dry pot of evaporation is equipped with temperature sensor, outside the dry pot of evaporation, be provided with high-frequency electromagnetic cartridge heater, stirring magnetic bar is equipped with in its inside, outer relevant position is provided with driving magnetic bar bottom it, drive magnetic bar to connect with drive motor.
Described stirring magnetic bar is to make the magnetic material of resistance to more than 280 DEG C high temperature.
The present invention compared with the existing technology has that firing rate is fast, homogeneous temperature, sealing thermal insulation are effective, the advantages such as test result is accurate.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the embodiment of the present invention.
