Bawo ni lati yan awọn ohun elo fun darí edidi

Yiyan ohun elo fun edidi rẹ jẹ pataki bi yoo ṣe ipa ninu ṣiṣe ipinnu didara, igbesi aye ati iṣẹ ohun elo kan, ati idinku awọn iṣoro ni ọjọ iwaju.

Asayan ti commonly lo ohun elo fun darí edidi.

6. petirolu, epo lubricating, omi hydrocarbon, 100 iwọn oruka gbigbe: tungsten carbide, 1Cr13 surfacing cobalt chromium tungsten; Oruka aimi: idẹ ti ko ni tabi resini lẹẹdi.

7. petirolu, epo lubricating, omi hydrocarbons, ti o ni awọn patikulu. Iwọn ti o ni agbara: tungsten carbide; Oruka adaduro: tungsten carbide.

Awọn iru ati awọn lilo ti awọn ohun elo ti npa awọn ohun elo ti o yẹ ki o pade awọn ibeere ti iṣẹ-ṣiṣe. Nitori awọn oriṣiriṣi awọn media lati wa ni edidi ati awọn ipo iṣẹ ti o yatọ ti ẹrọ, awọn ohun elo lilẹ nilo lati ni iyatọ ti o yatọ. Awọn ibeere fun awọn ohun elo lilẹ jẹ gbogbogbo:

1. Ohun elo naa ni iwuwo to dara ati pe ko rọrun lati jo media.

2. Ni o yẹ darí agbara ati líle.

3. Ti o dara compressibility ati resilience, kekere yẹ abuku.

4. Ko rọ tabi decompose ni awọn iwọn otutu giga, ko ṣe lile tabi kiraki ni awọn iwọn otutu kekere.

5. O ni iṣeduro ibajẹ ti o dara ati pe o le ṣiṣẹ fun igba pipẹ ni acid, alkali, epo ati awọn media miiran. Iwọn didun rẹ ati iyipada lile jẹ kekere, ko si faramọ oju irin.

6. Alasọdipúpọ edekoyede kekere ati resistance resistance to dara.

7. O ni o ni irọrun lati darapo pẹlu awọn lilẹ dada.

8. Ti o dara ti ogbo resistance ati ti o tọ.

9. O rọrun lati ṣe ilana ati iṣelọpọ, olowo poku ati rọrun lati gba awọn ohun elo.

Roba jẹ ohun elo edidi ti o wọpọ julọ ti a lo. Ni afikun si roba, awọn ohun elo idamu ti o dara miiran pẹlu graphite, polytetrafluoroethylene ati ọpọlọpọ awọn edidi.
