Abstract
The utility model relates to a quick analysis instrument for oil liquid quality, which is used for testing the deterioration degree of lubricating oil or other oil bases and has wide application. With a detection circuit with double vibration bridges and double holes, the utility model compares the dielectric constant variation of tested oil to determine and evaluate the oil quality. The utility model is capable of self-compensating humidity, and is a right-hand man for oil management; simultaneously, the utility model has certain meaning for the lubricating management of equipment.
Description
The utility model belongs to the electric detective technology field, relates to a kind of improved oil quality quick analytic instrument.
The domestic and international at present instrument that is used for oily express-analysis that uses is divided into two kinds basically with regard to it detects principle: a kind of is the transparency of measuring fluid with photovoltaic principals, thereby judges oily variation.For example: the oil quality analyzer that Japan, Sweden produce mostly belongs to this type of, and the TOD-1 type machine oil analyzer that the spy of China naval flies to be developed also belongs to this type of.The major defect of this oil quality analyzer is incomplete to the character of oil test reflection, and authenticity is relatively poor, as just judging sneaking into of the viscosity of fluid and unexpected impurity thereof etc.; Another kind is to differentiate oily intensity of variation by the dielectric changing condition of test fluid itself.For example: " NI-2B " type oil quality analyzer that U.S. north instrument and meter company produces.The quick oil quality analyzer of HF-1 type that the YZF-1 type oil quality analyzer of China Jinan radio six factories development and Shanghai China positive electron instrument plant produce etc. all belongs to this series products; this class oil quality analyzer is owing to adopt simple eye formula sensor measurement, and environmental difference (humidity, temperature variation) influence measuring accuracy greatly and be difficult to remedy.
The purpose of this utility model is to overcome the deficiency of prior art, and promptly first kind of oil is sent out and analysed instrument and reflect that oily qualitative change is complete, authenticity is poor; Second kind of test error that oil quality analyzer is bigger because of environmental difference causes provides a kind of high precision, the adaptive oil quality quick analytic instrument of high environment.
Realize that the technical solution of the utility model is to adopt two bridge eyes formula sensing circuits that shake, and two sensors are installed on panel, make oil quality quick analytic instrument provided by the utility model have automatic temperature-adjusting, humidity compensate function, and improve measuring accuracy because of the compensate function of two bridge circuits that shake.
Accompanying drawing 1 is a functional module schematic diagram of the present utility model.
Accompanying drawing 2 is a panel of the present utility model.
Accompanying drawing 3 is a kind of physical circuit figure of the present utility model.
Among the figure: (1) power supply, (2) voltage stabilizing, (3) permanent vibration source,
(4) power amplifier (5) resonance bridge, (6) bridge difference read,
(7) sensor, (8) sensor, (9) meter reading,
(10) adjusting knob, (11) switch,
(12) panel, (13) signal generator,
(14) amplifier stage, (15) bridge-type resonant circuit,
(16) stabilized voltage supply.
Describe the utility model in detail below in conjunction with accompanying drawing.
When power supply (1) is connected, during source of stable pressure (2) power supply, permanent vibration source (3) makes the square-wave signal that produces one group of 5MHz, this square-wave signal enters the double resonance bridge circuit of being made up of inductance, capacitive transducer (7), regulating capacitor (10), capacitive transducer (8) (5) through power amplification circuit (4), the amplitude of resonance is 5V, and frequency is 5MHz.When in sensor (7), adding new mark oil, and when in sensor (8), adding the used old oil of same model, owing to containing impurity, oil reason such as oxidized in the oil, make the specific inductive capacity of oil rise, produce imbalance on two resonance bridges, this imbalance just reflects in bridge difference meter reading (9).

The utility model is because its good environmental suitability and measuring accuracy can be widely used in fast qualitative ground test oil qualitative changeizations such as factory floor, field work.
Claims (1)
1, a kind of oil quality quick analytic instrument of being made up of sensor, switch, housing, meter reading, adjusting knob and basic circuit is characterized in that adopting two bridge eyes formula sensing circuits that shake, and two sensors are arranged on panel.
