Iyo yepamusoro-pressure pressure sensor YN52S00027P1 inokodzera SK200-6 yekuchera yeShengang.

◆ Pamusoro pezvinhu zvinoshandiswa mu-ultra-high pressure valves, kurapwa kwekupisa uye kuomeswa kwepamusoro kunowanzoshandiswa kuvandudza kupikisa kwavo kwe-extrusion uye kusagadzikana kwevhu.

1, vacuum kupisa kurapwa

Vacuum heat treatment inoreva nzira yekupisa iyo iyo workpiece inoiswa muvacuum. Vacuum kupisa kurapwa hakuburitse oxidation, decarburization uye kumwe kukora panguva yekudziya, asi zvakare ine basa rekuchenesa pamusoro, degreasing uye degreasing. Hydrogen, nitrogen uye okisijeni yakanyudzwa nezvinhu panguva yekunyungudutswa inogona kubviswa muvacuum, uye kunaka uye kuita kwechinyorwa kunogona kuvandudzwa. Semuenzaniso, mushure mekuvhiyiwa kwekupisa kweye-ultra-high pressure valve valve yakagadzirwa neW18Cr4V, kukanganisa kwekuda kwevharuvhu yetsono kunowedzera zvinobudirira, uye panguva imwe chete, maitiro emagetsi uye hupenyu hwebasa hunovandudzwa.

2. Surface kusimbisa kurapwa

Kuti uvandudze kushanda kwezvikamu, kunze kwekushandura zvinhu, mamwe maitiro ekusimbisa nzvimbo yekurapa anogamuchirwa. Zvakadai sekudzima kwepamusoro (kupisa kwemoto, kudziya kwepamusoro uye kwepakati frequency kupisa pamusoro pekudzimisa, kubata magetsi ekudziya pamusoro pekudzima, electrolyte kupisa pamusoro pemvura, laser electron beam kupisa pamusoro quenching, etc.), carburizing, nitriding, cyaniding, boronizing (TD nzira), laser kusimbisa, makemikari vapor deposition (CVD nzira), muviri vapor deposition (PVD nzira), plasma kemikari vapor deposition (PCVD nzira) plasma spraying, nezvimwewo.

Physical vapor deposition (PVD nzira)

Muvacuum, nzira dzemuviri senge evaporation, ion plating uye sputtering dzinoshandiswa kugadzira maion esimbi. Ioni dzesimbi idzi dzinoiswa pamusoro pechishandiso chekugadzira simbi, kana kuita nereactor kuti igadzire coating coating. Iyi nzira yekurapa inonzi physical vapor deposition, kana kuti PVD kwenguva pfupi. Iyi nzira ine zvakanakira yeyakadzika deposition tembiricha, 400 ~ 600 ℃ tembiricha yekurapa, diki deformation uye shoma pesvedzero pane matrix chimiro uye zvimiro zvezvikamu. TiN layer yakaiswa pavharuvhu yetsono yakagadzirwa neW18Cr4V nePVD nzira. Iyo TiN layer ine yakanyanya kuomarara (2500～3000HV) uye yakakwirira kupfeka kuramba, iyo inovandudza corrosion resistance yevharuvhu, haina corrosion mu dilute hydrochloric acid, sulfuric acid uye nitric acid, uye inogona kuchengeta nzvimbo yakapenya. Mushure mekurapa kwePVD, kupfeka kwacho kune chokwadi chakanaka. Inogona kuitwa pasi uye kukwenenzverwa, uye kushata kwayo kuri Ra0.8µm, inogona kusvika 0.01µm mushure mekupenya.
