Nzira yekuona kuramba:

Kutanga, kuongorora kutaridzika

Tarisa kuti zviratidzo zvakajeka, pendi yekudzivirira yakagadzikana, isina kupisa, mavanga, kuputika uye kuora, uye resistor iri pedyo nepini. Kune potentiometers, iwe unofanirwawo kutarisa kuti shaft inotenderera inoshanduka, elastic uye yakasununguka. Kana paine switch, tarisa kana switch yacho yakajairika, nezvimwe.

Chechipiri, iyo multimeter yekuona

1. Paunenge uchitonga kana kushorwa kwakanaka kana kwakashata nepointer multimeter, unofanira kutanga wasarudza giya rekuyeresa, wozoisa knob yegiya rekukudza mugiya rakakodzera. Kazhinji, RX1 giya rinogona kusarudzirwa resistors pazasi 100 ohms, RX10 giya reresitors pakati zana ohms uye 1kohms, RX100 giya re resistors pakati 1kohms uye 10kohms, RX1K giya re resistors pamusoro 100kohms.

2. Mushure mekusarudza giya rekuyera, gadzirisa giya rekupikisa re multimeter kusvika 0. Nzira yekuenzanisa 0 ndeyokuti: pfupi-circuit masimbi emasimbi ezviviri zveprobes zve multimeter, uye ona kana pointer inosvika panzvimbo ye0. Kana isiri panzvimbo ye0, gadzirisa chinongedzo che zero kugadzirisa knob kunongedza kune chinzvimbo che0 cheyero yekupikisa.

3. Zvadaro, shandisai maprobes maviri e-multimeter kusvika kumagumo maviri emushonga maererano, uye maprobes anofanira kunongedzera kuchiyero chekudzivirira chinoenderana. Kana iyo probes isingafambi uye isina kugadzikana, kana kukosha kwakaratidzwa kwakasiyana zvakanyanya kubva kune yakaratidzwa kukosha pane inopikisa, zvinoreva kuti resistor yakakuvadzwa.

4. Paunenge uchitonga kana kushorwa kwakanaka kana kwakaipa ne digital multimeter, tanga kugadzirisa giya knob ye multimeter kune yakakodzera gear ye ohm gear. Kazhinji, mazana maviri magiya anogona kusarudzirwa resistors pazasi 200 ohms, 200-2K ohms inogona kusarudzirwa 2k magiya, 20-20K ohms inogona kusarudzirwa 20k magiya, 200K-200M ohms inogona kusarudzirwa 2M ohms. Kupokana kwe2M-20M ohm ndeye 20M, uye kuramba kwe20M ohm kana kupfuura 200M.

Izvo zvakaunzwa pamusoro ndiyo nzira yekuona kunaka kwekupokana. Kuburikidza nenzira idzi dziri nyore dzekuona, unogona kukurumidza kuona kunaka kwekupokana, izvo zvinounza kurerukirwa kukuru pakushandisa kwako.

Chii chinoitika kana kuramba kwaputsika?

Kana kupokana kwaputswa, kazhinji kacho kupikisa kunowedzera, uye mamwe acho anozove madiki, kana mazhinji acho akavhurika.

Chiratidzo chei chatyoka kurwisa kuvhuvhuta?

Kupikisa kwechifuridzo kunonyanya kudzora kumhanya kwemhepo. Kana kuputika kwemhepo kwakaputsika, kumhanya kwemhepo kunofanana mumagiya akasiyana. Mushure mekupokana kwe blower kwatyorwa, iyo vhoriyamu yekudzora vhoriyamu knob inorasikirwa nekumhanya kwayo kwekutonga basa. Ichatungamirira mukusakwanisa kugadzirisa kubuda kwemhepo; Iko hakuna 1234 giya, chete mhepo yekubuda; Inofanira kuva yakakura kubuda kwemhepo; Kune zvakare mamwe mafeni asingashande zvakananga.

Kana varistor yakajairika, kushorwa kwayo kusingagumi. Iyo yakabatanidzwa mukufanana pamativi ese emagetsi emagetsi, ayo anoita basa rekudzivirira kwe overvoltage. Kana iyo voltage yekupinda ichipfuura imwe kukosha, kushorwa kwayo kunobva kwaita kudiki, zvichiita kuti dunhu ripfupike, nekumanikidza kupfupisa fuse, uye kutamba basa rekudzivirira midziyo yemagetsi. Mumamiriro ezvinhu akajairika, iyo inverter inokurumidza silicon iri nyore kutyora. Kana iyo rectifier silicon ikaputswa, panogona kunge paine kamwe kamwe overvoltage kana overcurrent. Nekuda kweiyo trigger kusagadzikana kunokonzerwa nekukanganisika kwemutoro uye kushanduka kwesimba, iyo inogadzirisa silicon ichakuvadzwa zvakare, uye iwo chaiwo matambudziko anofanirwa kuongororwa zvinoenderana nemamiriro ekukuvadza.

Chikonzero nei kupikisa kwe fan kwemota air conditioner kuchipisa zvichiramba;

1, compressor kana control circuit inokonzerwa nepfupi redunhu.

2, condenser mota, compressor electromagnetic clutch, evaporator mota kutadza.

3. Iyo fuse yemotokari yemhepo yemhepo fan haina kusangana nezvinodiwa, uye kukosha kwazvino kudiki.

4. Pane pfupi pfupi mumhepo inogadzirisa mhepo, iyo inokonzerwa nekuwanda kwecompressor load.
