Abstract

The invention discloses a method for detecting sealing of a supercharger midbody. The detection method comprises the following steps that 1, liquid with color is put into the supercharger midbody, and a water inlet and a water outlet of the supercharger midbody are sealed; 2, the supercharger midbody is put into glycerol to be heated to range from 100 DEG C to 120 DGE C; 3, the liquid in the supercharger midbody is expanded by being heated, if a leak exists in the supercharger midbody, the liquid with the color in the supercharger midbody can leak out, and whether the glycerol is discolored or not is observed. The real sealing condition of the supercharger midbody and whether the leak point exists or not can be detected by simulating the real operating temperature state of the supercharger midbody; by means of color contrast visualization, the leak fault point is identified, and sealing detection is easy, convenient and rapid.

Description

A kind of booster intermediate body method for conducting leak test

Technical field

The present invention relates to vehicle Charge device technical field, especially relate to a kind of booster intermediate body method for conducting leak test.

Background technology

When water-cooled supercharger report leaks anti freezing solution in the market, return and to do the inspection of ventilation applied voltage test after factory and do not measure intermediate and have leakage, can not find leakage position, cannot judge whether booster intermediate body has leakage, fault supercharger return to supplier place is checked, supplier does not have method yet, and inspection does not measure leakage position.

Traditional detection method is: blocked by the water delivering orifice of booster intermediate body, is immersed in by booster intermediate body in water, and booster intermediate body water inlet, by the gas of certain pressure, sees whether intermediate has gas leakage bubbling phenomenon.This detection method cannot judge whether booster intermediate body has leakage, cannot recurrence of failure, is difficult to detect.This kind of detection method does not consider the state in engine actual motion, in engine actual motion, anti freezing solution actual temperature through booster intermediate body may reach 97 DEG C, and gas blowing engine operationally, the temperature of the waste gas of discharging can reach more than 700 DEG C, supercharger working temperature can raise, and reaches as high as 150 DEG C.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of booster intermediate body method for conducting leak test, and its simulation booster intermediate body actual motion state of temperature, can detect booster intermediate body actual seal implementations.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

A kind of booster intermediate body method for conducting leak test, described detection method comprises the following steps:

1) coloured for band liquid is put into booster intermediate body, the water inlet of booster intermediate body and water delivering orifice are all sealed;

2) again booster intermediate body is put into glycerine to heat, be heated to 100-120 DEG C;

3) in booster intermediate body, heated liquid expands, and booster intermediate body is as existed leak, and the coloured liquid of band can leak out in booster intermediate body, observes glycerine whether variable color.

Wherein, the water inlet of described booster intermediate body and water delivering orifice are all sealed by plug screw and pad.

In described booster intermediate body, liquid is the red ink of dilution.

Described step 2) in, glycerine heats in beaker, and glycerine is by booster intermediate body submergence.

Magnetite is added in the glycerine of described beaker.

Thermometer is provided with in described beaker.

The present invention compared with prior art, has the following advantages: simulation booster intermediate body actual motion state of temperature, can detect booster intermediate body actual seal implementations, whether there is leakage point; Utilize color contrast visual come identified leakage trouble spot, sealing propertytest is simple and efficient.

Accompanying drawing explanation

Below the content expressed by each width accompanying drawing of this instructions and the mark in figure are briefly described:

Fig. 1 is booster intermediate body structural representation of the present invention.

In figure: 1. booster intermediate body, 2. plug screw I, 3. plug screw II.

Embodiment

Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.

As shown in Figure 1, this booster intermediate body method for conducting leak test, simulation booster intermediate body 1 actual motion state of temperature, detects at the temperature of actual operating mode.

Detection method comprises the following steps: 1) coloured for band liquid is put into booster intermediate body 1, the water inlet of booster intermediate body and water delivering orifice are all sealed; 2) again booster intermediate body is put into glycerine to heat, be heated to 100-120 DEG C; 3) in booster intermediate body, heated liquid expands, and booster intermediate body is as existed leak, and the coloured liquid of band can leak out in booster intermediate body, observes glycerine whether variable color.

Concrete detection method is as follows:

In 60ml water, add 4-5 drip red fountain pen water, water is become red;

With plug screw II 3, pad, the water delivering orifice of booster intermediate body is blocked, then the water inlet of red liquid from booster intermediate body is poured into, until after booster intermediate body volume is full of, finally with plug screw I 2, pad, the water inlet of booster intermediate body is blocked;

Being placed on by booster intermediate body is equipped with in the beaker of glycerine, and glycerine is glycerine, glycerine by booster intermediate body submergence, purity >=99.0% of glycerine, the boiling point of glycerine is 290 DEG C, in glycerine, add magnetite, prevents glycerine high temperature bumping; That the thermometer of 150 DEG C puts into beaker, the change of monitoring temperature at any time by range; Beaker is placed on electric boiling plate and glycerine is slowly heated to 110 DEG C.

If booster intermediate body has leakage, in booster intermediate body, red liquid will leak out, and is incarnadined by glycerine.Otherwise if intermediate does not leak, the color of glycerine can not become.Utilize color contrast visual come identified leakage trouble spot, sealing propertytest is simple and efficient.

Common leakage place of booster intermediate body is technique plug place.In testing process, when glycerine temperature rises to 90 DEG C, the red liquid in booster intermediate body oozes out from technique plug, and glycerine is slowly incarnadined; Along with temperature raises, seepage place starts to emit large bubble, and red liquid ceaselessly leaks out; When temperature is elevated to 110 DEG C, plug position bubble is increasing, and whole cup glycerine is dyed redness by the red liquid leaked out; Heating plate is stopped heating, glycerine is poured out, then booster intermediate body is taken out from beaker, see that booster intermediate body technique plug place ceaselessly emits bubble.

Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
