DHS Wiper Seal Gamit ang poly urethane(PU) bilang materyal
♠Paglalarawan-IDU Rod Seal
Ang DHS ay isang seal na pumipigil sa pagpasok ng alikabok, pinoprotektahan ang kagamitan at pinapanatili ang pagganap ng sealing. Gamit ang poly urethane(PU) bilang materyal, ito ay isang uri ng dust-resistant sealing element para sa double lip mouth.
Ang DHS Wiper Seal ay may double lip seal na may dust lip at oil seal lip. Ang istraktura nito ay ginagawang mahusay sa dust resistance at mas kaunting pagtagas ng langis. Bilang karagdagan, pinipigilan ng DH/DHS type double lip wiper ang pagpasok ng alikabok, dumi, buhangin at metal chips. Pangunahing ginagamit sa hydraulic cylinders at cylinders, Ang axial movement ng hoist at ang guide rod. Ang DHS Wiper Seal ay ang gumawa ng reciprocating piston movement.
