1. Nheyo dzekutanga dzekusarudza hardfacing
l Kuve nechokwadi chekupfeka kwakanaka uye kudzivirira zvirinani maturusi ekudzika senge majoini epombi yekudhirowa, huremu hwekuchera pombi, uye makora ekudhirowa. Kuomarara kwepamusoro kwebhandi risingapfeki hakufanire kudzika pane HRC55.
l Paunenge uchichera mubhokisi, kuitira kuchengetedza casing uye kuderedza kupera kwayo, bhanhire rakasarudzwa rinodzivirira rinofanira kuva rakanaka rinopesana nekushanda.
l Chiyero chine musoro chesainzi pakati pekuramba kupfeka uye kuderedza kukwesha.
l Kazhinji, zvinokurudzirwa kushandisa hardfacing ne "yakasimudzwa" chimiro, uye isingakurudzirwi kushandisa hardfacing ne "flat" chimiro. Chete kana iyo yakakura yekunze dhayamita yejojo pombi yejojo inogumira kuti usapindira mukati medhayamita yekasi, zvinokurudzirwa kushandisa "flat" yakaumbwa kupfeka-resistant strip. Chero rudzi rwemutsetse usingapfeki wakasungwa nenzira iyi haugone kuburitsa yakanyanya kusakara-inodzivirira mhedzisiro nekuti zvese zviri zviviri dhayamita rekunze rejojo yepombi yekuboorera uye tambo isingapfeki iri kupfekwa panguva imwe chete.
2. Mafungiro akajairika pakusarudza hardfacing
Misconception 1:Tungsten carbide kupfeka-resistant bhandi ndiro bhandi rakanakisa rinopfekwa rinoshandiswa kudzivirira zvibooreso.
Mushure mekunge tungsten carbide inomira-inodzivirira tambo yakasungirirwa pajojo yepombi yekuchera, iyo yakapinza tungsten carbide zvimedu zvinokonzeresa kucheka diki pane casing, zvichikonzera kupfeka kwakasimba kwecasing.
Mazhinji makambani emafuta ekunze ane zviyero zvemukati zvinorambidza zvakajeka kushandiswa kwe tungsten carbide hardfacing. Mimwe minda yeoiri yemumba inorambidzawo kushandiswa kwayo.

Misconception 2: Kusarudza hardfacing iyo inoteedzera zvakanyanya kudzikisira kukakavara uye kubayira kupfeka kuramba
l Kuti uchengetedze casing uye uderedze kupera kwayo, kutsvaga kwakanyanya kweiyo anti friction kuita kwebhanhire risingapindike bhandi rinopa kuramba kwayo kupfeka.
ü Bhandi rinodzivirira kupfeka rinopera nyore nyore, zvichiita kuti pave nekubatana kwakananga pakati pejojo yepombi yekuchera uye casing kana kugadzira chitsime. Sezvinozivikanwa, kupfeka pakati pejojo repombi yekubooresa isina chinhu uye casing kana kugadzira tsime rakakura kupfuura iro rejojo repombi rakabatana nebhandi risingapfeki, zvichikonzera kusakara kwakanyanya kwekasi uye kutadza kwekutanga kwepombi yekuchera. nekuda kwekunyanya kupfeka.
ü Hupenyu hupfupi hwebasa rekuomarara hunowedzera mari yavo yekushandisa.
