DHS Wisserseël met poli-uretan (PU) as materiaal
♠Beskrywing-IDU-staafseël
DHS is 'n seël wat verhoed dat stof binnedring, toerusting beskerm en seëlprestasie handhaaf. Deur poli-uretaan (PU) as materiaal te gebruik, is dit 'n soort stofbestande seëlelement vir dubbellipmond.
Die DHS-ruitveërseël het 'n dubbellipseël met 'n stoflip en 'n olieseëllip. Die struktuur daarvan maak dit uitstekend in stofweerstand en minder olielekkasie. Boonop verhoed die DH/DHS-tipe dubbellip-ruitveër die toetreding van stof, vuilgoed, sand en metaalskyfies. Dit word hoofsaaklik gebruik in hidrouliese silinders en silinders, die aksiale beweging van die takel en die geleidingsstang. Die DHS-ruitveërseël is om heen-en-weergaande suierbeweging te doen.
