Reboty Harusi Piyano Hinges For Doors

Heavy duty piyano hinges yemagonhiratidza kupikisa kwakanyanya kune brittle fracture pasi pekupisa kwakanyanya kusiyana uye nekukasira kukonzeresa mamiriro. Kuyedzwa kwe-temperature yakaderera yakaitwa maringe neISO 148 standard inoratidza kuti mushure mechando paminus 45 degrees celsius kwemaawa makumi maviri nemana, simba rinotorwa nehinge blade base rinosvika 47 joules, ukuwo mahinji ecarbon steel anongove ne23 joules patembiricha imwe chete, uye kusimba kunodarika 94%. Panguva imwecheteyo, kuyedza-kuchembera kwepamusoro kwakatora maawa chiuru mumhepo pa80 degrees Celsius maererano neGB/T 3512 standard. Kuwedzera kwekuvhura nekuvhara torque yehinge kwaingova 6.2% yemutengo wekutanga, iyo yakaderera zvakanyanya kupfuura iyo 20% yekuwedzera inowanzoonekwa muindasitiri. Izvi zvinoita kuti magonhi esimbi achiri kukwanisa kusundidzirwa uye kudhonzwa zviri nyore kunyange kana akasangana nezuva muzhizha. Mukuwedzera, kutarisana nemigumisiro inokonzerwa nekuvhara nguva dzose, 5.5kg pendulum inoshandiswa kurova pakati peshizha remukova nekukurumidza kwemamita maviri pasekondi. Mushure memakumi maviri,000 akateedzana maitiro, hinge axial gap increment ingori 0.11mm, zvichinyatso kudzivirira shizha remusuwo kubva pakudonha.

 

 

Iyi hinge inoitawo zvakanaka maererano nekupokana kwemakemikari corrosion uye kusunungura. Mushure mekunge mahinji anyudzwa muine acidic solution ine pH value ye 2.5 uye alkaline solution ine pH value ye11.5 kwemaawa 300 zvakateerana, kupfekwa kwepamusoro kwaingoratidza kushanduka kudiki uye pasina makomba ekuora mumatrix. Kuora uremu hwaive 0.3 mg per square centimeter uye 0.2 mg per square centimita zvichiteerana, nepo hinge isina kudzivirirwa yakarasika kupfuura 2.1 mg mune acidic mhinduro. Nezve -kuregedzeka kwekuita munzvimbo-yenguva refu yekuzunguzika, bvunzo yelateral vibration yakaitwa maererano neISO 16130 standard. Mushure mekunge hinge yaramba ichizunguzika kwemaawa makumi maviri nemana paamplitude ye plus or minus two millimeters and a frequency of 25 Hz, yasara pretightening force of the fastening nut ichiri kuchengetedza 92% yeukoshi hwekutanga. Kana tichienzanisa, mahinji akajairwa asina anti{17}}anosunungura dhizaini angosara ne64%. Izvi zvinoita kuti ive sarudzo inovimbika kune nzvimbo dzine mavibrations akasimba akadai semadhoo epadivi penhandare yekutakura mikwende nemadhoo akakwirira{20}pachiteshi chechitima chinomhanya.
