Abstract
This is a liquid medium drain leakage testing method. Its features are: On the tested member's lower part is installed the temperature sensor to test the drain leakage liquid medium temperature. It is different to temperature of environment, and sends this electric signal to the computer, then by the curve of the real time to dynamic recording the condition of the drain leakage of liquid medium.
Description
Technical field:
The present invention relates to the detection method of micro liquid.
Background technology:
The detection method of present water clock, commonly used is manual method, also useful quality testing method (promptly detecting the variation of quality with balance), photoelectric detection method (promptly interdicting the method for photosignal with drop).Manual method, labour intensity is big, is not the direction of development; The quality testing method needs high-precision day gentle facility such as shockproof, windproof, photoelectric detection method: because the conversion of detected medium, light transmission is affected, and the both very easily is subjected to the interference of environment, and produce spurious signal or lossing signal, reduced the reliability that detects.
Summary of the invention:
The object of the present invention is to provide a kind of detection method that is applicable to the reliable liquid medium of automatic detection/automatic control system
The invention provides a kind of detection method of liquid medium water clock, it is characterized in that: with placing the temperature sensor that detects the below, position, thermopair for example, detection is different from the temperature of the liquid medium drip of testing environment temperature, and the drip temperature transition become electric signal, and deliver to computing machine and carry out subsequent treatment, with the method for real-time curve test parameters is carried out the dynamic tracking record, reach with computing machine and detect alternative artificial visually examine, to adapt to the needs of automatic detection/automatic control system.
In the detection method of liquid medium water clock provided by the invention, can as the temperature of raising liquid medium, or reduce the testing environment temperature by liquid medium is carried out adjustment, increase the difference of drip temperature and testing environment temperature, with the temperature signal of strengthening being detected.
In the detection method of liquid medium water clock provided by the invention, drip is collected in a place, in case the drip in the motion is lost and lossing signal with oil intercepter.
In the detection method of liquid medium water clock provided by the invention, in the drip temperature that record detects, parameter with corresponding sensor liquid medium condition of work, as temperature, pressure, working time, rotating speed etc., and convert each parameter to electric signal respectively, deliver to computing machine,, analyze and definite direction that produces the reason of water clock and improve design so that the researchist determines to produce the situation of water clock.
In the detection method of liquid medium water clock provided by the invention, place the temperature sensor that detects the below, position to be preferably thermopair.
In the detection method of liquid medium water clock provided by the invention, computing machine can also be equipped with alarm and carry out oil dripping warning and parameter off-limit alarm, so that the operator on duty in time handles, avoids having an accident.
The advantage of the detection method of liquid medium water clock provided by the invention is: method is easy, reliability is high, can and write down use for automatic detection.
Description of drawings:
Fig. 1 is a leather cup experiment detection device synoptic diagram.
Embodiment:
The leather cup experiment detection device as shown in Figure 1.
On fuel tank (5) sidewall leather cup mount pad (9) is arranged, on air release (6) is arranged, fuel outlet valve (11) is arranged down, go up and link to each other with draft tube (19), fuel tank (5) lining has well heater (17) and temperature sensor B (18), and support (12) is arranged outside the fuel tank (5); Have pressure transducer (7) and air release (8) on the draft tube (19), pressure transducer (7) provides the signal of working pressure in the fuel tank; Support (12) is used for fixing temperature sensor A---thermopair (1) and speed probe (2); Speed probe (2) provides the signal of the working speed of turning axle (3).
During test, leather cup (4) is installed on the leather cup mount pad (9), oil intercepter (10) is installed on the leather cup mount pad (9) again, oil dripping hole vertical table face downwards when oil intercepter (10) is installed.The anterior more downward-sloping angle of thermopair (1) (remove head, expose even head) through repacking is installed on the test bracket (12) oil dripping hole of even aligning oil intercepter (10).Mobile working fuel tank (5) is inserted in leather cup (4) on the turning axle (3), then actuating medium (lubricating oil) is injected fuel tank (5), and turning axle (3) contacts the oil dripping phenomenon generation that do not have of (obturaging) position with leather cup (4).
Behind the starting characteristics test device, the oil temperature in the fuel tank (5) will reach 119 degree, and turning axle (3) high speed rotating carries out the test of hundreds of hour.
Check the sealing of leather cup (4) in the process of the test.When oil impregnate and oil leakage phenomenon take place, oil droplet will be with turning axle (3) along this diameter of axle to spilling.The effect of oil intercepter (10) is that the oil that will spill collects, because oil intercepter (10) is connected with the metal position of oil box (5), the oil temperature is transmitted on the oil intercepter (10) through metal parts, oil droplet still keeps higher temperature, when oil droplet thermopair (1) when oil dripping hole drips is experienced temperature variation, send electric potential signal and give data acquisition unit, prompting is handled and provided to computing machine on display.The appropriate temperature-measuring range of thermopair and the resolution characteristic that time constant can guarantee detected signal selected.
According to signal, on registering instrument, can find the condition of work that oil impregnate or leakage of oil moment take place: the time that the pressure and temperature of fuel tank (5) lining, the rotating speed of turning axle (3) and leather cup (4) were worked from thermopair (1).
Claims (6)
