Five, embodiment:
Among Fig. 1-4: datalogger (1), control box (2), analyzer case (3), pre-service case (4), control box (2) links to each other by cable with analyzer case (3), and analyzer case (3) links to each other by pipeline with pre-service case (4); Pre-service jar (20) is arranged in the pre-service case (4), and pre-service jar (20) entrance point oil pipe (22) links to each other with Crude Oil Transportation pipe sample tap, outlet termination analyzer case (3) oil pipe (19); The interior fixed displacement pump of analyzer case (3) (21) import connects oil pipe (19), fixed displacement pump (21) outlet connects oil pipe (6), oil pipe (6) divides two-way oil pipe (7), oil pipe (8) to be connected with cold core (13) with sensor (5) respectively by three-way connection (12), and sensor flowline (10) links to each other with total flowline (11) with cold core flowline (9).There is heating tape all oil pipes and pre-service jar (20) outside.After the heating and filtration of oil sample through pre-service jar (20), fixed displacement pump (21) in the case (3) is sent in the oil pipe (6) by analysis, oil pipe (6) divides two-way oil pipe (7), oil pipe (8) by three-way connection (12) and is connected with cold core (13) with sensor (5) respectively, and sensor flowline (10), cold core flowline (9) are connected with total flowline (11).
Sensor (5) is made up of a sensor inner core (14) and a sensor sleeve (15); A temperature probe (17) is housed in the cold core (13), and cold core (13) is by semiconductor cold reactor (18) cooling refrigeration, and semiconductor cold reactor (18) is dispelled the heat by water tank (16).Temperature probe (17) is connected with registering instrument (1).During work, arbitrary place crude oil sampling mouth of pipe on the oil pipeline is linked to each other with pre-service jar of the present utility model (20) entrance point, total flowline (11) is connect recycling can; Outside water supply pipe is connected in the water inlet of water tank (16); Connect power supply.
Not during refrigeration, because cold core flowline (9) ratio sensor (5) position is low, tested oil sample flows out from cold core flowline (9), no oil sample passes through in the sensor (5), medium between its sensor inner core (14) and the sensor sleeve (15) is an air, and sensor inner core (14) is 20pF with the capacitance that sensor sleeve (15) forms electric capacity; During semiconductor cold reactor (18) beginning refrigeration, the interior temperature of cold core (13) reduces, the interior oil sample temperature of cold core (13) of flowing through decreases, when oil sample solidifies in the cold core (13), oil sample in the cold core (13) stops to flow, oil sample and enters out oil tank by sensor flowline (10) through total flowline (11) in oil pipe (7) flow sensor (5).Medium between sensor inner core (14) and the sensor sleeve (15) changes, the capacitance that forms between sensor inner core (14) and sensor sleeve (15) increases to about 40pF, can be judged as the interior oil sample of cold core (13) and be in curdled appearance this moment, the interior temperature probe of cold core (13) (17) measured temperature is current oil sample solidifying point value just, and is shown and record by registering instrument (1).The field technician can in time adjust corresponding process parameters according to these data.Control box (2) inner control system stops refrigeration after obtaining the detection signal that sensor (5) sends, heat up to oil sample, dissolves in the cold core (13) and solidifies oil sample, and change next refrigeration over to and detect the cycle of operation, and constantly circulation.
Among Fig. 5: media variations between sensor inner core (14) and sensor sleeve (15), the capacitance that causes forming therebetween changes, and causes that oscillatory circuit equivalent voltage value changes.Equivalent voltage compares by comparator circuit, when not reaching the comparator circuit setting value, and output detection signal not, when reaching the comparator circuit setting value, i.e. output detection signal.
