The airtight testing principle of air-conditioned cold store air tightness detection apparatus and method
Air-conditioned cold store air tightness detection apparatus measures gas by the way of filling positive pressure in strict accordance with the airtight examination criteria of air-conditioned cold store
Adjust the leakage rate of storehouse.Referring to the airtight examination criteria of air-conditioned cold store, according to the volume of air-conditioned cold store, every 100m3The leakage area of permission
It is necessarily less than and is equal to 0.4cm2。
Air-conditioned cold store air tightness detection apparatus main operational principle: device inflate mouth by hose connect air-conditioned cold store airtight inspection
Mouth is surveyed, pressure sensor connects the pressure detecting mouth of air-conditioned cold store.After starting air tightness detection apparatus, air pump is started to work, toward library
Room inflatable body slowly forms positive pressure in controlled atmosphere storehouse, and touch screen pressure history, device adjust automatically aeration quantity make at this time
Pressure sensor numerical stability, i.e. positive regulation in storehouse.Storehouse air-tightness can determine whether by pressure drop time curve at this time.
Air-conditioned cold store air tightness detection apparatus application method
Example 1: the air-tightness of No. 1 air-conditioned cold store of detection
No. 1 air-conditioned cold store volume: long 7m × depth 12m × high 7.8m=655.2m3
After connecting air tightness detection apparatus and pressure sensor, pressure and time dependent parameter are set, starting is airtight certainly
Motion detection device, device are started to work, and are inflated to storehouse, slowly form positive pressure in controlled atmosphere storehouse, observe touch screen pressure at this time
Change curve makes pressure sensor numerical stability timing 10 minutes at 100Pa, stable state, passes through the reading of gas flowmeter
Number, the capacity size for calculating air outlet pump is 80.3 liters per minute, i.e., negative pressure is that amount of leakage when 7mm water column is high is in library
80.3L/min, by tabling look-up, the leakage area of the library is 1.8cm in this state known to (subordinate list 1)2, the library is calculated with this
Every 100m3Leakage area are as follows:
655.5 × 100=0.27cm of S1=1.8 ÷2<0.4cm2
The 0.27cm of the leakage area of i.e. No. 1 air-conditioned cold store2, meet common air-conditioned cold store airtightness criteria；According to the leakage area,
When setting No. 1 storehouse leak-stopping time, if leak-stopping cycle set is 100s, the leak-stopping time of No. 1 controlled atmosphere storehouse can be set as
70s or so.
Example 2: the air-tightness of No. 2 air-conditioned cold stores of detection
No. 2 air-conditioned cold store volumes: long 7m × depth 12m × high 7.8m=655.2m3
After connecting air tightness detection apparatus and V-type differential pressure indicator, start air tightness detection apparatus, air pump is started to work, and library is drawn
Room gas arrives the external world by arranging after gas flowmeter, slowly forms negative pressure in controlled atmosphere storehouse, observe V-type pressure gauge at this time, and adjust
Section manually adjusts valve, and the negative regulation 7mm water column for stablizing the water-column on pressure gauge in 7mm, i.e., in storehouse is high, surely
Determine timing 1 minute under state, by the reading of gas flowmeter, the capacity size for calculating air outlet pump is 80.3 liters per minute,
It is 187.4L/min that negative pressure, which is amount of leakage when 7mm water column is high, i.e. in library, by tabling look-up known to (subordinate list 1) in this state
The leakage area of the library is 4.2cm2, the every 100m of the library is calculated with this3Leakage area are as follows:
655.5 × 100=0.64cm of S2=4.2 ÷2>0.4cm2
The 0.64cm of the leakage area of i.e. No. 2 air-conditioned cold stores2, do not meet common air-conditioned cold store airtightness criteria；User should in use
Before air-conditioned cold store, the leak point of the library need to be searched and carry out respective handling, detect the library gas according still further to identical method after having handled
Close property, until reaching standard requirements.
The above are merely preferred embodiments of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this
The protection scope of utility model.
