Ngationei kuti kuedza kunoenzaniswa sei

Muhupenyu, tinowanzotarisana nemamiriro ezvinhu apo zvinodiwa kuti tione kuoma: kutema, mamiriro emhepo kana kuomeswa kwemhepo yakamanikidzwa kana gasi mumutopi. Ngationei, chii ichi chizhinji chemuviri. Uye pakarepo mubvunzo unotevera unomuka: chii chiyero chekumanikidza? Icho chinotarisa kuti kune mhando dzakasiyana dzezviyero zveyero inoshandiswa kune huwandu hwepanyama. Muchikamu chino, tichaongorora kukosha kunoenzaniswa. Saka, ngatitange nokutarisa mumwe nomumwe wezvikamu izvi.

Iyo yakagamuchirwa yakajeka yeHIV SI chirongwa ichi chinomanikidzwa chikwata Pascal (Pa), zvinyorwa zvaro zvii kilopascal (kPa) uye megapascal (MPa). Mumwe Pascal akaenzana nechiyero chinotevera: 1 Pa = 1 N / m ² . Zvisinei, mumakambani akasiyana-siyana, zvakasiyana- siyana zvinoshandiswa zvinoshandiswa. Somuenzaniso, pakugadzira simba regesi uye kubuda kwemhepo yakamanikidzwa (mune compressor teknolojia), zvikamu zvakasiyana zvakasiyana zvakasiyana zvekuyera zvinogona kushandiswa.

Tichaongorora kukosha kwekumanikidzwa kwegesi nemhepo. Iyo huru unit inoshandiswa inomubhiti mita imwe paminiti yenguva (m ³ / min). Kazhinji munhu anogona kuwana zviyero zvakadai seyita paminiti (l / min) kana kuvharwa kwemhepo (atm), uye munyika dzekutaura chiChirungu zvinogona kushandisa tsoka yekubhiti paminiti - gumbo rekubhiti yemakumbo, kana CFM. Ngationei chiyero chezvizhinji izvi. 1 l / min inofananidzwa ne 0.001 m ³ / min, uye 1 CFM yakaenzana ne 28.3168 l / min, kana 0.02832 m ³ / min. Nokudaro, 1 m ³ / min ndeye 35.314 CFM. Kazhinji kacho, kushanda kunoshandiswa kunonyorera kana mumamiriro ezvinhu akadai (1 atm pa200 ° C). Muchiitiko ichi, usati wasvika pachikwata chekuyera, isa mutsara "n", zvinoreva zvinowanzoitika. Somuenzaniso, 10 nm ³ / min.

Uyewo kuenzanisa kuoma, masuniti akadaro anogona kushandiswa: mm Hg. Art. (Torr) - millimeter ye mercury; Atm. - mamiriro emuviri; At. - technically atmosphere; Bar. Munyika dzekutaura chiRungu , kukosha kwakadai sepaundi pa-square inch-PSI (mapaundi nehafu inch) inogona kushandiswa.

Funga nezvehuwandu hwezvikamu zvekudzivirira kwemaitiro: 1 megapascal ine 10 bar kana 7500.7 milimita ye mercury, kana 9,8692 mumamiriro emhepo, 10.197 teknolojia yekudenga, uye 145.04 PSI.

Saka takabvisa chiyero chekumanikidzwa mune zvakasiyana-siyana zvekombiyuta. Uye ndezvipi zvishandiso zvinoshandiswa pakuyera zviyero zvakadaro?

Aya maitiro anosarudzwa maererano nehuwandu hwehuwandu hwekuyeresa (somuenzaniso, mhepo yakadzika, yakawandisa kana isingawaniki, iyo inopisa), uye, zvechokwadi, maererano neshoko rekuita (mvura, membrane, magetsi, masikati uye akabatanidzwa). Iyo inonyanya kukosha, iyo inoratidzirwa nechigadziro chekuyera mweya kushanda - ndiko kukodzera kirasi. Kune nzira dzakawanda dzakadaro. Heano magwaro makuru ayo anowanzoshandiswa mukuyera kumanikidzwa kwemhepo:

• Bharometer-aneroid, inoshandisa kuyera dambudziko remhepo;
• Barothermohygrometer, yakashandiswawo kuyera dambudziko remhepo;
• Mushonga wezvinokonzera zvinoshandiswa - anoshandiswa pakuyera musiyano mukudzvinyirira;
• Analog uye digital manometers.

Kutaura muchidimbu, ngatitii ruzivo pamusoro pemagetsi anokwanisa kunobatsira chero munhu upi zvake wemazuva ano.
