Abstract
The utility model relates to a speed quality testing instrument for liquid luboil by measuring the capacity with the electricity. The speed quality testing instrument for liquid luboil is composed of a sensor, a trigger circuit, a time-base circuit, an operational amplifier circuit and a display circuit. Because the sensor is in the crossly parallel type or in the concentric cylindrical type, the speed quality testing instrument for liquid luboil needs small oil quantity to test. The speed quality testing instrument for liquid luboil has simple and reliable structure. The speed quality testing instrument for liquid luboil is generally used for the fast quality testing of various liquid luboil.
Description
The method that the utility model relates to a kind of electricity consumption reaches the fast monitored device of test liquid quality of lubrication oil by the testing capacitor amount.
Judge that at present can gasoline engine and the employed machine oil of diesel engine continue to use, all be to be undertaken by human eye and experience, so just bring bigger error, even make the oil exchange that still can continue to use fall to cause waste, also can make rotten out of use machine oil also continue to use, cause mechanical inordinate wear, adopt physics, chemistry, then method is numerous excessively for optical method measuring oil, can not adapt to.It is 87207503 devices that are called diesel engine oil matter monitor that the Chinese patent communique disclosed application number on May 18th, 1988, though this device solves the miniaturization issues of oily monitoring device, but because uncertainization of sensor, cause in numerous and diverseization of aspects such as monitoring and influence monitoring accuracy.
The purpose of this utility model be to provide a kind of simple, fast, working stability is reliable, highly sensitive, the electric test device of the quick test liquid oil ageing degree that cost is low.
The utility model is according to electrical principles, by to oil each index and dielectric coefficient, the relation during electricity is led and research and design.
The utility model is by sensor, trigger circuit, time base circuit, computing circuit, zeroing circuit, display circuit, power supply is formed, it is characterized in that: sensor is made of two arc pole plates which is provided with the plurality of tooth-shaped bar, perhaps constitute by two concentric cylindrical pole plates, profile of tooth bar on its two arcs pole plate is set up for intersecting mutually, two concentric cylindrical pole plates are that suit is set up, 2 pin of the two-plate of sensor and 0.5NE55.6 integrated package, 3 pin join, thereby formation trigger circuit, space between the two-plate is not more than 1 cubic centimetre, and the medium between the pole plate is air or measured object.
Its principle of work is: after the two-plate of sensor obtains tested oil sample, the electric capacity or the conductance of sensor change, make trigger circuit produce an oscillation frequency, 6,4 pin that 9 pin of the oscillation frequency that produces under standard sample that this oscillation frequency and time base circuit produce by IC2-2 output to IC2-1 mix, obtain a difference frequency signal, amplify the promotion gauge outfit through computing circuit through the 5 pin output of IC2-1.Obtain reading.
Because detected sample and standard difference are big more, the difference frequency that obtains is also big more, and then gauge outfit deflection is big more, according to national standard or actual requirement, can directly read the situation of tested oil from gauge outfit.
Advantage of the present utility model is: the sample that only need take a morsel can minute in measure the oil of lubricating oil, really provide a kind of can be blanket, install small and exquisite, the practical and reliable pick-up unit.
Figure one is the utility model electrical schematic diagram;
Figure two, figure three are the utility model sensor construction synoptic diagram;
The utility model can be realized like this:
1, sensor adopts flat capacitance type, is one and sets up the capacitor that some slice combined crosswise become separately by two arc pole plates, perhaps dresses up a capacitor by two concentric cylindrical pole plate covers;
Base integrated package and capacitance-resistance original paper were formed when 2, time base circuit was by diac and 1/2NE556;
Base integrated package and corresponding capacitance-resistance original paper were formed when 3, time base circuit was by 1/2NE556,
4, computing circuit adopts low power consume high-operational amplifier integrated package and corresponding capacitance-resistance original paper to form,
5, display circuit is made up of the direct current table and the capacitance-resistance original paper of 150 emblems peace, changes the index scale that is carved with the monitoring of profit oil that is carved with according to metric system on the demonstration reading dial of table into,
6, zeroing circuit is made up of amplifier integrated package and multi-circle spiral flow potentiometer and resistance.
Above-mentioned each position circuit is according to Figure of description one formation of joining.
In use, as long as at first mix up zero-bit by zero potentiometer, it is one after another drop of on sensor to get measured oil, can read the oily situation of measured oil from display circuit.
Claims (3)
1, a kind of liquid lubrication oil quality high speed monitor, it is by sensor, and trigger circuit, time base circuit, computing circuit, zeroing circuit, display circuit, power supply are formed, and it is characterized in that:
A: sensor is made of two arc pole plates which is provided with the plurality of tooth-shaped bar, perhaps is made of two concentric cylindrical pole plates;
B: the two-plate of sensor during with 1/2NE556 basis set become fast 2 pin, 3 pin to be connected, constitute trigger circuit.
2, liquid lubrication oil quality high speed monitor according to claim 1 is characterized in that the profile of tooth bar on the two arc pole plates is set up for intersecting mutually, and two concentric cylindrical pole plates are that suit is set up.
3, liquid lubrication oil quality high speed monitor according to claim 1 is characterized in that the space between the two-plate is not more than 1 cubic centimetre, and the medium between the pole plate is air or measured object.
