Mapaipi eSimbi Yemhando Yepamusoro Ari Kutengeswa Mufananidzo Wakaratidzwa

Tsananguro pfupi:

Mapaipi edu esimbi yekabhoni akasungirirwa nesimbi yakagadzirwa kuti igare munzvimbo dzakaoma, ichivimbisa kuvimbika uye kugara kwenguva refu. Kunyangwe muchida mapaipi ekugadzira zvivakwa, mashandisirwo esimba kana chero mamwe maindasitiri, zvigadzirwa zvedu zvakagadzirwa kuti zviite basa repamusoro.

Mapaipi edu anogadzirwa nekukanda simbi ine kabhoni shoma muzvikamu zvemachubhu pamakona chaiwo ekutenderera, zvichiteverwa nemaitiro akasimba ekunamira kuti ive nechokwadi chekuti misono yacho yakasimba uye inogara kwenguva refu. Iyi nzira itsva yekugadzira inotibvumira kugadzira mapaipi esimbi ane dhayamita yakakura kwete chete yakasimba asiwo inochinjika, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana kubva pakuvaka kusvika pakufambisa mafuta negasi.

Fekitori yedu iri pakati peguta reCangzhou, Hebei Province uye yave iri kutungamira muindasitiri yemapombi esimbi kubvira payakatangwa muna 1993. Fekitori iyi ine nzvimbo inosvika 350,000 square metres uye ine tekinoroji yemazuva ano nemichina, zvichitigonesa kugadzira mapaipi esimbi emhando yepamusoro anosangana nezvinodiwa pasi rose. Nezvinhu zvese zvinosvika RMB 680 miriyoni uye vashandi vakazvipira 680, tinodada nekuzvipira kwedu kune kugona uye kugutsikana kwevatengi.

Kuedzwa kweHydrostatic

tsananguro yechigadzirwa1

Pombi inofanira kumira bvunzo ye hydrostatic pasina kubuda nemusono we weld kana muviri wepombi.
Majoini haafanirwe kuongororwa ne hydrostatic, chero bedzi zvikamu zvepaipi zvinoshandiswa pakuisa chiratidzo pajoini zvakaedzwa ne hydrostatic zvisati zvaitika.

Kubatsira Kwechigadzirwa

1. Chimwe chezvakanakira zvikuru zvemapaipi edu esimbi yekabhoni akasungirirwa nesimbi inotenderera ndiko kugona kugadzira mapaipi ane dhayamita hombe. Izvi zvinoitwa kuburikidza nemaitiro ekugadzira akasiyana anosanganisira kuputira simbi yakapfava muzvikamu zvemachubhu nekona yakatarwa yemupendero wobva wabatanidza mipendero yacho.

2. Nzira iyi haingowedzere simba uye kugara kwenguva refu kwepombi chete, asiwo inobvumira kuchinjika mukugadzirwa uye mashandisirwo.

3. Mapaipi edu haapindi ngura uye anogona kumira kumanikidzwa kwakanyanya, zvichiita kuti akwanise kushandiswa mumaindasitiri akasiyana-siyana anosanganisira mafuta negesi, mvura, uye kuvaka.

Kushaikwa kwechigadzirwa

1. Maitiro ekugadzira, kunyangwe achibudirira, anogona kutungamira mukuchinja kwemhando kana akasatariswa zvakanyanya.

2. Mutengo wekutanga wemhando yepamusoropombi yesimbizvingava zvakakwirira pane dzimwe nzira dzepasi, izvo zvingava zvekufunga nezvazvo pamapurojekiti anonyanya kukoshesa bhajeti.

3. Kunyange hazvo mapaipi edu akagadzirwa kuti agare kwenguva refu, angangoda kugadziriswa nguva nenguva kuti ave nechokwadi chekuti anogara kwenguva refu, kunyanya munzvimbo dzakaoma.

Musika

Misika yedu mikuru yakapararira munzvimbo dzakasiyana-siyana, zvichiita kuti tikwanise kusangana nezvinodiwa nevatengi vedu pasi rese. Tinodada nekupa mapaipi esimbi emhando yepamusoro asingangosviki chete asiwo anopfuura mwero weindasitiri. Kuzvipira kwedu pakudzora mhando uye kugutsikana kwevatengi kwatiwanira mukurumbira semutengesi akavimbika kuindasitiri yesimbi.
