Process pombi test, purura uye kuchenesa chirongwa

1. Mamiriro ezvinhu uye gadziriro yeCraft Pipe Test Pronders

I.1.Iyo pombi inopedzwa uye inoenderana nezvinodiwa nemirairo.

I.2.Bazi, iyo hangero uye pombi yapedzwa, uye kuongororwa kwehombodo kwakasvikwa zvachose

I.3.Kudzvinyirira kwekudzvinyirira geji kwakasimbiswa, iko kurongeka kwakaiswa kune 1.5, uye iyo yakazara kukosha kweiyo tafura inofanira kunge iri 1.5 kune kaviri kudzvinyirirwa kwakanyanya kuyerwa.

I.4.Pamberi pemuedzo, iyo yekuedzwa system, zvishandiso uye zvakabatanidzwa muyedzo yemiedzo, uye chinzvimbo chebhofu bofu chinoshandiswa kushandisa iyo chena lacquer mucherechedzo uye rekodhi.

I.5.Mvura yeyedzo inofanira kushandiswa nemvura yakachena, uye iyo chloride ion zvirimo mumvura haifanire kupfuura 25 × 10-6 (25 ppm).

I.6.Pombi yenguva pfupi yebvunzo inosimbiswa, uye kuchengetedzeka uye kuvimbika kunofanirwa kuongororwa.

I.7.Tarisa uone kana mavharu ese ari pombi iri pamusoro pehukama, kunyangwe iyo scers inowedzerwa, uye iyo yekudzoreredza vhezheni ndeyekubviswa, uye mushure mekunge purge inogona kugadzirwazve.

2. Process testline bvunzo

2.1.Pipe test kudzvinyirirwa ndeye 1.5 times kugadzirwa kwekumanikidza.

2.2. Kana pombi uye michina inoedzwa sehurongwa, kudzvinyirirwa kwepombi kwakaenzana kana kushoma pane kudzvanywa kwechishandiso, uye nguva yekuedza iyo isingasviki 1.15 nguva yekugadzira pombi, uye inogona kuedzwa maererano nekudzvinyirira kwemidziyo.

2.3.Hen hurongwa hwakaiswa, mweya wacho unofanirwa kupera simba, iyo yekumira yemhepo inofanirwa kuve yakakwirira kwazvo pombi yemapipi, uye wedzera vharuvhu rinopera.

2.4. Kune mapepa nemisiyano mikuru, kudzvinyirira kweiyo bvunzo yepakati kunofanirwa kuyerwa mukudzvinyirira kwekuedzwa. Kudzvinyirira kwekuyedza kwepombi kunofanirwa kuve pasi pekumanikidza pane yakakwirira point, asi yakadzika nzvimbo yekumanikidza haifanire kupfuura iyo tube zvikamu.

2,5. When the pressure is pressed, the boost should be slow, and after the test pressure is reached, it is regulated for 10 min, and there is no deformation without leakage. Dzvinyiriro yekuyedza inodonha kuDanho rekugadzira, inomira maminitsi makumi matatu, uye kumanikidzwa hakudiri, hapana kubhururuka kunokodzera.

2.6. Pashure pomuedzo, ndiro bofu rinofanira kubviswa munguva, uye mvura yakaiswa, uye kudzvanywa kwakaipa kunofanira kudzivirirwa kana kuidururwa, uye hakufanirwe kuderedza mvura. Kana leak rikawanikwa panguva yekuedzwa, hazvifanirwe kuongororwa, mushure mekubvisa hurema, inofanira kuongororwa.

2.7.Muedzo wetsiva wakaitwa mushure mekuedzwa kwekumanikidza apfuura, uye svutugadzike yemhepo yakashandisa mhepo yakamanikidzwa.

2.8.

3. Craft pombi kuchenesa uye kuchenesa

3.1. Process technology zvinodiwa

3.1.1. Maitiro Pombi Inofanirwa Kuganhurwa uye Kuchenesa (Kunongedzera Kuchenesa).

3.1.2. Nzira yekuputika inotsanangurwa maererano nezvinodiwa zvekushandiswa kwepombi, maitiro akasviba emukati mekushanda kwepakati nepombi.

3.1.3. Usati waputika, chiridzwa chiri mukati mehurongwa chinofanira kuchengetedzwa uye bvisa ndiro orifeta, iyo yekugadzirisa vharuvhu uye iyo yakadzoserwa vharuvhu muviri, nezvimwewo, nemazvo, uye zvakadai, uye zvakadai, uye zvakadai, uye zvakadai.

3.1.4. Kana ichinge ichinatsa, iyo tsvina iri mumuziya haifaniri kupinda mumidziyo, uye tsvina yakaridzwa kunze kwechishandiso haizopinda pombi, iyo vhesi yekuvharira inowedzerwa.

3.1.5. PIPE ichinatsa inofanira kunge yakayerera yakakwana, uye kudzvanywa kwesvina hakufanirwe kupfuura kumanikidzwa kwekugadzira, uye huwandu hwekuyerera kazhinji husiri pasi pe20 m / s. Paunenge uchinatsa, shandisa huni huni kurova iyo tube, uye tarisa pane weld uye pasi pombi, asi haifanire kukuvadza pombi.

3.1.6. Bazi redavi rinofanira kutariswa vasati vavhuvhuta, uye kukwikwidza kwehurume kunofanirwa kusimbiswa pazvinenge zvakakodzera.

3.2. Pipe kucheneswa, kuchenesa nzira

3.2.1. Mvura Inoshanyira: Kushanda Svikiro ndiyo pombi yeiyo yemvura system. Mvura Rinsing inogona kusvika iyo yakakwira kuyerera chiyero kana kwete isingasviki 1.5 m / s mune tube. Iyo inokodzera kumvura kunze kwenyika uye kujeka nepamusuwo. Pashure pokunge pombi yasukwa, mvura yacho inofanira kupera nguva nenguva.

3.2.2.Mhepo Kuchenesa: Kushanda Svikiro kunocheneswa zvishoma nezvishoma nezvikamu zvakamanikidzwa pamhepo pipi pipi. Kana iwe ukasangana neValve, iwe unofanirwa kubvisa kumberi kwekutenderera kubhodhi yekudonha, wobva wagadzirisa zvakare mushure mekunge pombi yabhururuka. Dzvinyiriro haifanire kudarika mudziyo uye pombi dhizaini yekumanikidza, uye huwandu hwekuyerera harifanire kunge uri pasi pe20 m / s. Munguva yekuchenesa yemhepo, apo gasi rekuputa racho risiri kuputa, chiteshi chetsvina chinoiswa muchiteshi chakapusa kuti chifukidze huni, uye hapana marara, uye mamwe marara pane imwe tarisiro mundiro 5 min.

3.2.3.Steam Purge: Iyo yekushanda svikiro inonatswa ne steam mune steam pombi. Steam yakanatswa tube isati yanonoka Gasi rinopaza mumupovutugadzike rakamisikidzwa kumusoro, uye mucherechedzo wacho unobata ziso. Iyo yekubvisa pipe diameter haifanire kunge iri pasi peyakaderera yeyurge tube. Qualitified Standard: Double kutsiva tarisiro yekaviri nguva dzakateedzana, dzakadai sekuti mavara anoonekwa neziso rakashama pane iyo tarisiro yemapepa emafuta 0,1mm, kudzika kwedzidzo ndeye 1 / cm2; Iyo nguva yekunyepa ndeye maminitsi gumi nemashanu (kureva maviri pane imwe nguva, yapfuura.
