The utility model has the advantages of reasonable instrument layout, convenient operation, high and stable temperature control precision and accurate and reliable test result.
Description
The utility model relates to a kind of lubricating oil demulsification pH-value determination pH instrument, is used for measuring the ability that oil product is separated from emulsion.Usually be applicable to steam turbine oil, also be applicable to other lubricating oil.ICL is: G01N 5/00.
At present, in testing experiment, adopt the glassware of given size specification, interim matched combined is got up.Technological means such as the heating of being adopted, measurement are all relatively backward.Chinese invention patent (87104391.2) discloses a kind of " device of oil, liquid water content in the weight method automatic gauge oil water mixture ".This invention is a kind of continuous online oil water mixture automatic gauge method and device.On the thin neck of an overflow cylinder, feed pipe is housed, be with the film isolation pocket in the feed pipe lower end, be full of working fluid in the overflow cylinder, the film isolation pocket freely swells with the increase of tested volume of mixture, the working fluid of extruding simultaneously injects through run-down pipe contains the tube that overflows, determine the volume and weight of tested potpourri through two electronic balances, handle the total flow that mathematical model obtains tested potpourri, profit content and shunt volume separately with microcomputer.Continuous online oil water mixture a kind of more advanced method of can yet be regarded as is being handled in this invention, but in that to measure the ability that oil product separates from emulsifying agent just inapplicable, and also slightly complicated of this device.
The purpose of this utility model is just in order to solve weak point of the prior art, and proposed a kind of lubricating oil demulsification pH-value determination pH instrument.This instrument is that relatively backward method is improved, and forms advanced instrument, makes measurement simple and reliable.
The purpose of this utility model is achieved in that
Lubricating oil demulsification pH-value determination pH instrument is made up of valve pipeline, cable bearer, rack, distribution cabinet, instrument panel, cabinet guide rail and glass door etc.Wherein separate to bathe and be connected with steam generator by vapour line, the steam pipe and the oil-holder UNICOM of drawing by steam generator, insert temperature sensor in the oil-holder and together place among the emulsifying bath with refrigeratory, rod-type well heater, being the magnetic stirring machine below emulsifying bath, is arc-shaped heater below steam generator.
The purpose of this utility model can also be further perfect by following steps:
In the cabinet of lubricating oil demulsification pH-value determination pH instrument, luminaire is set, Power Regulation speed regulator and digital display temperature controller.
The utility model has 2 width of cloth accompanying drawings, and wherein Fig. 1 is a most preferred embodiment of the present utility model, also can make the accompanying drawing of specification digest.
Fig. 1, be structural representation of the present utility model;
Fig. 2, be side view of the present utility model.
The utility model compared with prior art has following advantage: 1. instrument layout rationally, Easy to operate; 2. accuracy of temperature control is high and stable; 3. result of the test accurately, reliably.
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described further.
Most preferred embodiment of the present utility model as shown in Figure 1, lubricating oil demulsification pH-value determination pH instrument, by valve pipeline 4, cable bearer 7, rack 11, distribution cabinet 13, instrument panel 15, compositions such as cabinet guide rail 19 and glass door 20, wherein separate bathing 1 is connected with steam generator 2 by vapour line, the steam pipe and oil-holder 6 UNICOMs of drawing by steam generator 2, insert in the oil-holder 6 temperature sensors 3 and with refrigeratory 5, rod-type well heater 9 together places among the emulsifying bath 3, it below emulsifying bath 3 magnetic stirring machine 14,16, below steam generator arc-shaped heater 10.Luminaire 12, Power Regulation speed regulator 11, digital display temperature controller 18 also are set in cabinet.
At the trial, pour 20 milliliters on sample in oil-holder 6, and be placed in the frame of emulsifying bath 3, on oil-holder 6, wherein a hole is plugged in temperature sensor 8 and its mercury bottom is adjusted to apart from 20 millimeters～25 millimeters places, test tube bottom the cork gag that has two holes.Make steam pass through steam lead, disappear until condensed fluid.Then, pull down steam lead, and its another hole of passing cork is inserted in oil-holder 6, make the tip of pipe touch the center of oil-holder 6 bottoms from proofed sleeve.Cooperate too tightly between steam lead and the cork.Proofed sleeve is received on the steam lead again, controlled temperature by the screw clamp on steam regulation conduit and the steam drain, the flow velocity of steam should make the indicated oily temperature rise to 88 of temperature sensor in the oil-holder 68 ℃～91 ℃.The oil temperature rise is to the time of this point, and unusual with oil properties is 45 seconds～75 seconds, in entire test, all should have enough steam to discharge in a large number from the exit in the steam generator 2.Continuously logical steam, the volume of condensate water and oil should reach 40 ± 3 milliliters (volume of deduction steam lead and temperature sensor, about 12 milliliters～15 milliliters) in 4 minutes to 6.5 minutes oil-holders 6.If the time is less than 4 minutes, then may be owing to the steam humidity, or water not be blown out by steam fully in the steam lead, test this time should be cancelled.
Pull down steam lead from proofed sleeve, and start stopwatch immediately, promptly oil-holder 6 is transferred to 93 ℃～95 ℃ separation and bathe in 1, from oil-holder 6, take out temperature sensor 8 and steam lead.Write down the oil reservoir volume of once telling every 30 seconds.If the interphase between oil reservoir and the emulsion be not one clearly, during straight horizontal line, then all assign any lacelike emulsion layer as the water layer part.The position of this line should be estimated 0.5 milliliter, and 20 milliliters of times that oil is required told in record.If in 20 minutes, do not isolate 20 milliliters of oil, then stop test, and write down the oil reservoir volume of separating.
The arithmetic mean that will meet twice measurement result of precision requirement is got accurate to 15 seconds, as the demulsification value.If do not isolate 20 milliliters of oil in 20 minutes, the demulsification value was greater than 1200 seconds.
Utilize the utility model to test, its method is simple, and test result is accurate.
