The course of work of the present utility model is as follows:
Under the management of controller, the course of work of whole pipeline is divided into sample introduction by the sequencing of action, constant temperature, sampling, test, and five big steps such as cleaning, oven dry, division is as follows:
1, sample introduction
Pack into about the about 20ml of oil sample of lubricating cup at every turn, not quantitatively very not strict to Ubbelohde viscosity tube sample introduction, but the handing-over mouth that can not be higher than the side pipe and the person in charge, and adverse current viscosity tube sample introduction quantitatively just there is a strict demand, oil sample can not be less than the inlet of overflow bubble, and the amount of oil sample must enter the porch that overflow is steeped by oil sample.
2, constant temperature
Because the relation of viscosity and temperature is very close, sample enters viscosity tube must have adequate time to make the heat-conducting medium of sample and temperature controlling groove carry out heat interchange fully, make sample before test, reach the probe temperature of temperature controlling groove control, with the accuracy that guarantees that kinematic viscosity is measured, be called constant temperature time during this period of time, and how many constant temperature times sets, according to measuring accuracy requirement, accuracy requirement is high more, constant temperature time must be long more, set 20 minutes in the constant temperature time machine, each switch valve of temperature constant state and vacuum pump all are in power failure state promptly:
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 |
(the A1-A6 switch valve is a three-way solenoid valve here, and state in the table " 1 " expression switch valve or vacuum pump are in "on" position " 0 " expression power failure state " nothing powers up ")
At this moment three of viscosity tube outlets all communicate with atmosphere, and sample is concentrating under the effect of gravity in the storage bubble.
3, sampling
Before the test, must help by means of the draft of vacuum pump the sample in the side pipe is sent into the storage bubble, finish the sampling step.This step can save when using the Ubbelohde viscosity tube to detect, and the adverse current viscosity tube sample time is actually drainage time, must set, and the "on" position of each switch valve of this course of action and vacuum pump is as follows:
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 1 | 0 | 1 | 0 | 0 | 1 | 1 |
4, test
For modified Kan Nongfencike--reverse flow type viscometer allows all switch valves and vacuum pump dead electricity promptly after finishing the step of sampling:
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 |
At this moment three of viscosity tube ports all communicate with atmosphere, test solution slowly flows downward through kapillary under the effect of gravity, on the pipe three pairs of photoelectricity being housed altogether monitors the liquid level that flows, when liquid level is flowed through first group of photoelectricity, controller begins to clock with 0.02 second accuracy of timekeeping, clocks for the first time when liquid level arrives second pair of photoelectricity and finishes, and clocking for the second time begins simultaneously, when liquid level arrives the 3rd pair of photoelectricity, the end of clocking for the second time.
The end back control device that clocks for twice calls built-in calculation procedure, calculates test result, stores data simultaneously and goes out test result by printer prints.
5, viscosity tube cleans
After end of test (EOT), must clean viscosity tube, keep the clean and tidy of viscosity tube.In order to save cleaning fluid, the way that the raising cleaning performance takes to be interrupted into cleaning fluid cleaning repeats several circulations, do not add setting if the number of times of wash cycles can manually be set, just undertaken by the number of times of setting in the machine, each wash cycles all comprises following step.
(1) row's sample+advance cleaning fluid
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 1 | 1 | 1 | 1 | 1 | 0 | 1 |
The sample that stores bubble is discharged to waste liquid bottle by A4, A3, A5, pump, advances cleaning fluid (2) from A1 simultaneously and wait for 6S
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 0 | 0 | 1 | 0 | 0 | 0 | 1 |
The time of waiting for allows the abundant Soak Test pipe of cleaning fluid, pump not stop keeping the continuity of work.(3) take out on to clean and measure bubble
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 1 | 0 | 1 | 0 | 1 | 0 | 1 |
Cleaning solvent reaches waste liquid bottle and cleans drain the simultaneously purpose of waste liquid of arm to reach by being extracted on the arm.(4) advance cleaning fluid once more
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 1 | 1 | 1 | 1 | 1 | 0 | 1 |
(5) wait for 6S
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 0 | 0 | 1 | 0 | 0 | 0 | 1 |
(6) by the kapillary discharge opeing
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 0 | 1 | 1 | 0 | 1 | 0 | 1 |
Cleaning fluid reaches waste liquid bottle and cleans drain the simultaneously purpose of waste liquid of hair system pipe to reach by being extracted on being responsible for.
6, oven dry viscosity tube
After the cleaning, viscosity tube must be dried.Ready for using next time, as a circulation, whole drying course needs some circulations to drying course with four actions, and cycle index can also can be used machine internal fixation parameter by keyboard to set up, and each oven dry do action state is as follows:
(1) make viscosity tube and whole pipeline form negative pressure
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 1 | 1 | 1 | 0 | 1 | 0 | 1 |
(2) take out person in charge's atmosphere from A4, A2 enters
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 0 | 1 | 1 | 0 | 0 | 0 | 1 |
(3) vacuumize together action (1)
(4) taking out the side pipe atmosphere enters from A3, A2
| A4 | A3 | A5 | A1 | A2 | A6 | Pump |
| 1 | 0 | 1 | 0 | 0 | 0 | 1 |
A6 does not work in the drying course, A5, pump be in running order all the time-that is to say that variable valve blocks all the time, and vacuum pump is constantly bled, and the diameter of storage is stored the key component that bubble just becomes oven dry greater than the outlet diameter of viscosity tube.Therefore switch valve A4, A3, A5, A2 energising in step (1), (3), the powerful draft of vacuum pump makes and forms higher vacuum in the viscosity tube, the stream of A3, A2 ventilation afterwards pours from storing the bubble bottom with higher speed, steep the top that bottom liquid takes storage to storing, the bore of storing top sharply shrinks, and gas velocity is accelerated, therefore can be successfully with the cleaning fluid sucking-off, store oven dry through repeatedly just making repeatedly, if the higher viscosity tube drying course that quickens of temperature in the while temperature controlling groove.
The utility model can be provided with two groups of testing tubes simultaneously, and two groups of testing tubes cooperate independently pipeline and switch valve, by the unified control of control device.Control device 60 is gone back the LCDs that connecting band touches, by the LCDs setup parameter, order and show test results, by printer 90 and print the result.The utility model adopts non-volatile mass-storage system, can store 400 historical records simultaneously, and set parameter also all has automatic preservation.
Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
