Izikali nokucindezelwa yokulinganisa

Ingcindezi Izikali - idivayisi (amadivayisi) sokulinganisa imingcele gas ingcindezi, uketshezi. Amadivayisi zihlukaniswa izinhlobo eziningana, kuye ngezimpawu. Ngaphambi ukhetha manometer sokulinganisa ingcindezi, kudingeka ufunde imininingwane ukusetshenziswa kwazo.

Ukukhetha idivayisi ngokuvumelana kulinganiswa ingcindezi ububanzi

- Pressure geji. Insimbi asetshenziswa ukukala umehluko omuhle phakathi kwengcindezi ngokuphelele futhi ingcindezi barometric ku uhla kusuka 0,06 1000 MPA.

- ulinganisa. Izinyathelo cleaner kuze 40 KPA.

- Umshini. Usebenzela sokulinganisa ingcindezi ngezansi ambient (asemkhathini) kufika ku-100 KPA.

- ulinganisa. Izinyathelo okuncane ingcindezi ngokweqile (40 KPA).

- ulinganisa. Ukumeda ububanzi zivumelana esingaba kusuka - 20 kuya + 20 KPA.

- manometers. Lokhu kuhlanganisa ingcindezi Izikali sokulinganisa ingcindezi ngokweqile (60 ukuze 240000 KPA), kanye cleaner (kufika ku - 100 KPA).

- Umehluko ingcindezi geji. Idivayisi yakhelwe yokulinganisa umehluko ingcindezi.

Indlela esetshenziswa kakhulu kukhona umehluko nokucindezelwa ngokuphelele zomculo. kudivayisi Ukwahlukaniswa (Izikali) sokulinganisa umehluko ingcindezi phakathi kwamanani amabili kuboniswe. manometers ngokuphelele abonisa ingcindezi value, kungakhathaliseki iyehla iyenyuka emkhathini.

Izici, izakhiwo manometers

Izikali sokulinganisa ingcindezi zihlukaniswe izinhlobo eziningana, kuye ngokuthi umklamo kanye nesakhiwo imikhiqizo: ketshezi, deadweight, ulwelwesi ukusonteka, lo ukusonteka emthonjeni ijabulise (Bourdon tube). Umniningwane kwenza ukukala ingcindezi lelisetulu degree lokunemba.

Diaphragm ingcindezi Izikali kusetshenziswa imithi. Bangabaholi okumsulwa kakhulu ngokuya kwemvelo, ikhwalithi mercury kungekhona ukuthi sezizimbi kakhulu.

Kuyinto Izikali evame kakhulu for ukulinganisa ingcindezi gas. Zakhiwa umzimba lapho kukhona amamitha. Amadivayisi ukufakwa compressors, amaphampu imishini igesi. Negesi Izikali kuqondile e ukufundwa.

Izikali kwanoma yiluphi uhlobo ihlukaniswa ngokweminyaka ukunemba izinkomba. I umncane inombolo, ithuluzi ibonisa inani elifanele ngaphezulu. ukunemba amakilasi zimi kanje: 0.15; 0.25; 0.4; 0.6; 1.0; 1.5; 2.5; 4.0.

Ububanzi Izikali

Onenjongo Izikali eziningi. Eza abaxhumana kagesi, jikelele lobuchwepheshe, inkomba, i-recorder, injongo ekhethekile.

- kagesi contact manometer isetshenziswa ukulawula kanye nesilinganiso ingcindezi ku ketshezi, gaseous, ezindaweni ze-non-ezonakalisayo.

- Izikali Obshchetehnichesky asetshenziswa ukukala ingcindezi umusi, igesi, uketshezi.

- I-ONLINE LIBRARY Izikali abe okusezingeni eliphezulu nokunemba rate. Bakha ukuhlolwa futhi yokulinganisa namanye amadivayisi. Ngokuvamile, basuke efakwe deadweight zedivayisi.

- Pressure Izikali nge rekhoda fixed ingcindezi Ukufundwa at indlela ekhethekile esiphathiswa.

- Pressure Izikali izinjongo ezikhethekile ukunikeza zezemvelo oyifunayo. Lezi zihlanganisa: i-oksijini (blue), acetylene (omhlophe), i-hydrogen (oluhlaza) amadivaysi. imibala ehlukene edingekayo ukuze ugweme imiphumela engemihle. Ngokwesibonelo, kumele i-oksijini amathuluzi degreased, noma okunobuthi kudivayisi zihlangana nomoya-mpilo okumsulwa yokuqhuma.

Ingcindezi geji yokulinganisa ingcindezi uphethiloli ingasetshenziswa kulezo zimboni. Lapho ekhetha idivayisi, kufanele wazi ukuthi umkhiqizo izinga angathengwa kuphela ovela nomkhiqizi elihle nge idumela emhlabeni wonke. Umenzi kumelwe unelayisensi udaba izimpahla, isitifiketi izinga. Lena yokuthi kubaluleke kakhulu. Ngemva yokulinganisa amadivayisi elisetshenziswa izinqubo eziyinkimbinkimbi kwezobuchwepheshe kanye ukukhiqizwa. Futhi ukunquma ukuphepha intuthuko kanye nekhwalithi umkhiqizo wokugcina.
