chii chiri Chisimbiso cheChitubu/Chitubu chine Simba Chisimbiso/Variseal?

Chisimbiso cheChitubu / Chitubu chine Simba Chisimbiso / Variseal chinhu chepamusoro chekuisa chisimbiso chine U-shaped Teflon yemukati yakakosha chitubu.Nekushandisa yakakodzera chitubu simba uye sisitimu yemvura kudzvanywa, muromo wekuisa chisimbiso (chiso) unosundirwa kunze uye nekutsikirirwa zvinyoro nyoro pamusoro pesimbi yakavharwa kuti igadzire yakanakisa yekuisa chisimbiso.Iyo actuation mhedzisiro yechirimo inogona kukurira kushoma eccentricity yesimbi mating pamusoro uye kupfeka kwemuromo wakavharwa, uku uchichengeta inotarisirwa yekuisa chisimbiso kuita.

Teflon (PTFE) chinhu chekuvharisa chine chepamusoro chemakemikari kuramba uye yakanaka kupisa kupisa kana ichienzaniswa neperfluorocarbon rabha.Inogona kuiswa kune yakawanda yakawanda yemakemikari emvura, zvinonyungudutsa, pamwe nehydraulic uye mafuta ekuzora.Kuderera kwayo kwekuzvimba kukwanisa kunobvumira kushanda kwenguva refu yekuisa chisimbiso.Zvitubu zvakasiyana-siyana zvakakosha zvinoshandiswa kukurira matambudziko akasimba ePTFE kana mamwe mapurasitiki erabha epamusoro-soro, Zvisimbiso zvakagadziridzwa zvinogona kutsiva huwandu hukuru hwekushandisa mune static kana dynamic (inodzokorodza kana kutenderera inofamba), ine tembiricha kubva pafiriji kusvika 300 ℃. , uye kumanikidzwa kunotangira kubva pavacuum kusvika kune-ultra-high pressure ye700kg, ine kukurumidza kwekufamba kusvika ku20m / s.Zvitubu zvinogona kushandiswa mumhando dzakasiyana-siyana dzekupisa zvinopisa zvinwiwa nekusarudza simbi isina tsvina, Elgiloy Hastelloy, nezvimwe zvinoenderana nenzvimbo dzakasiyana dzekushandisa.

Chisimbiso chechirimoinogona kugadzirwa zvinoenderana neAS568A standardO-ringgroove (yakadai se radial shaft seal,piston chisimbiso, axial face seal, etc.), kutsiva zvachose O-ring yepasi rose.Nekuda kwekushaikwa kwekuzvimba, inogona kuchengetedza kuita kwekuvhara kwakanaka kwenguva yakareba.Semuenzaniso, kune ma mechanical shaft seals anoshandiswa munzvimbo dzepamusoro-soro dzinoparadza mu petrochemical process, chinonyanya kukonzera kudonha hakusi kungopfeka kusina kuenzana kwemhete inotsvedza, asiwo kuparara uye kukuvara kweO-ring.Mushure mekuchinja kuHiPerSeal, matambudziko akadai sekunyorovesa kwerabha, kuzvimba, kukwenya kwepamusoro, uye kupfeka zvinogona kuvandudzwa, nekudaro zvakanyanya kunatsiridza hupenyu hwesevhisi yemakanika shaft zvisimbiso.

Chisimbiso chechirimo chakakodzera kune ese ari maviri ane simba uye static application.Pamusoro pekuisa chisimbiso munzvimbo dzepamusoro-tembiricha dzinoparadza dzataurwa pamusoro, yakanyatsokodzera kuvhara zvikamu zvemhepo neoiri pressure cylinders nekuda kweiyo yakaderera sealing lip friction coefficient, yakagadzikana yekuisa chisimbiso kusangana nekumanikidza, kumanikidza kwepamusoro, inobvumidzwa yakakura radial kumhanya. kunze, uye groove saizi kukanganisa.Iyo inotsiva U-yakaumbwa kana V-yakaita compression kuti iwane yakanakisa yekuisa chisimbiso kuita uye hupenyu hwesevhisi.

Kuiswa kweSpring Seal

Iyo rotary spring seal inofanira kuiswa chete mumigero yakashama.

Kuti uwirirane ne concentricity uye kusagadzikana kuisirwa kuisirwa, tevera anotevera matanho:

1. Isa chisimbiso mugomba rakashama;

2. Isa chivharo pasina kuomesa kutanga;

3. Isa shaft;

4. Gadzirisa chivharo pamuviri.

Hunhu hwe spring seal sezvinotevera:

1. Kuiswa chisimbiso hakukanganiswi nekusakwana kwemafuta panguva yekutanga-up;

2. Zvinobudirira kuderedza kupfeka uye kupesana kwekudzivirira;

3. Kuburikidza nekubatanidzwa kwezvinhu zvakasiyana-siyana zvekuisa chisimbiso uye zvitubu, masimba akasiyana ekuisa chisimbiso anogona kuratidzwa kuti asangane nezvinodiwa zvakasiyana-siyana zvekushandisa.Special CNC machining michina inoshandiswa, pasina mold cost - kunyanya yakakodzera nhamba shoma yezvikamu zvakasiyana-siyana zvekuisa chisimbiso;

4. Kurwisana nemakemikari ekuora uye kupisa kupisa kwakakwirira zvikuru kune inowanzoshandiswa sealing rubber, ine zviyero zvakagadzikana uye pasina kuora kwekuita chisimbiso kunokonzerwa nekuputika kwevhoriyamu kana kuderera;

5. Yakanakisa chimiro, inogona kuiswa mune yakajairika O-ring grooves;

6. Kuvandudza zvakanyanya kuisa chisimbiso uye hupenyu hwebasa;

7. Iyo groove yechinhu chekuisa chisimbiso inogona kuzadzwa nechero anti-pollution material (yakadai sesilicone) - asi haikodzeri nzvimbo dzemwaranzi;

8. Sezvo iyo yekuisa chisimbiso ndeyeTeflon, yakachena kwazvo uye haina kusvibisa maitiro.Iyo friction coefficient yakadzikira zvakanyanya, uye kunyangwe mukumhanyisa yakaderera maapplication, yakatsetseka isina chero "hysteresis effect";

9. Kudzikira kwekutanga friction kuramba, inokwanisa kuchengetedza yakaderera yekutanga simba rekuita kunyangwe muchina wakavharwa kwenguva yakareba kana uchishanda nguva nenguva.

Kushandiswa kweSpring Energized Seal

Chisimbiso chechirimo chinhu chakakosha chekuisa chisimbiso chakagadzirirwa maapplication ane yakanyanya tembiricha corrosion, yakaoma lubrication, uye yakaderera friction.Iko kusanganiswa kwezvinhu zvakasiyana-siyana zveTeflon composite, mapurasitiki einjiniya epamberi, uye zvitubu zvesimbi zvisingadziviriri zvinogona kuzadzisa zvizere zvinodiwa zvakasiyana-siyana zveindasitiri.Yakajairika application inosanganisira:

1. Axial zvisimbiso zvejojo ​​rinotenderera rekurodha uye kuburitsa ruoko;

2. Zvisimbiso zvekupenda mavharuvhu kana mamwe maitiro ekupenda;

3. Zvisimbiso zvepombi dzevacuum;

4. Chinwiwa, mvura, midziyo yekuzadza doro (zvakadai semavharuvhu ekuzadza) uye zvisimbiso zveindasitiri yezvekudya;

5. Zvisimbiso zvemotokari uye maindasitiri emuchadenga, semagiya ekutungamirira magetsi;

6. Zvisimbiso zvekuyera midziyo (yakaderera friction, hupenyu hurefu hwebasa);

7. Zvisimbiso zveimwe nzira yekushandisa kana midziyo yekumanikidza.

Simbisa musimboti sezvinotevera:

PTFE ndiro chitubu musanganiswa U-yakaita chisimbiso mhete (pan plug chisimbiso) inoumbwa nekushandisa yakakodzera chitubu tension uye system fluid kudzvanywa kusundira kunze kwekuvhara muromo uye zvinyoro nyoro kudzvanya pamusoro pesimbi yakavharwa, ichigadzira yakanakisa yekuisa chisimbiso.
