Description

A kind of condensation point experimental rig of the novel metal cryostat based on mercury switch control

Technical field

The utility model relates to a kind of detection device more particularly to a kind of novel metal cryostats based on mercury switch control Condensation point experimental rig.

Background technique

The condensation point of oil product refers under prescribed test conditions, will be contained in invisible spectro oil sample cooling and tilt 45 It spends after after one minute, the maximum temperature that pasta no longer moves.So the condensation point of oil product is detected, wherein very crucial Two procedures are: 1, the test tube equipped with sample needs the refrigeration in cryostat；2, whether invisible spectro oil sample, which forms condensation point, need to do 45 Spend inclination and timing one minute.Then by observation, the judgement whether invisible spectro oil sample flows is made, finally obtains the examination The condensation point value of sample.

Currently, the instrument of domestic same type, using two kinds of cryostats, one is alcohol liquid cryostats；One is solid metals Bath.In alcohol cryostat slot, oil sample, which does 45 degree of common methods of overturning, is: alcohol cryostat slot is motionless, only will be in alcohol cryostat Test tube in slot does 45 degree of overturnings.In solid metal bath, oil sample, which does 45 degree of common methods of overturning, is: metal bath is connected Do 45 degree of overturnings together with test tube.

Wherein, using alcohol liquid cryostat, because alcohol has volatility, laboratory technician needs to grasp and understand alcohol in time The situation of alcohol amount in cryostat slot, timely supplements alcohol, more troublesome.

Using solid metal bath, solve the problems, such as that alcohol volatilizees in alcohol cryostat slot, but it is reported that, it is based on mercury Switch control, 45 degree of overturnings and timing one minute solid metal bath, integral combined still lacks.
