SPRING ENERGIZED SEAL

To ensure the sealing lip stays in place,
替換規格一次確認

把舊密封件、溝槽圖面與工況傳來,一起核對密封外套、內置彈簧與配合尺寸,找出替換或客製方向。

密封外套彈簧型式溝槽尺寸運動條件
CHALLENGES FACED

找彈簧增能密封時,您也遇到這些狀況嗎?

低壓或啟停時密封位置滲漏 低壓或啟停時,密封位置一直滲漏?
密封件反覆更換仍磨耗洩漏 密封件反覆更換,磨耗與洩漏還是回來?
裝進溝槽後密封失效 材質看起來能用,裝進溝槽卻密封失效?

WHY CHENGSHIN

外套、彈簧與溝槽,一起確認才配得準

先看介質、溫度、壓力與運動方式,再核對密封唇、彈簧與配合面,把反覆失效的線索逐項收斂。已有舊件、圖面或料號,就從現有資料開始。

6 Key Advantages of Chengxin Springs' Enhanced Sealing Technology

每一步確認,讓材料、規格與設備條件對得起來。

Identifying the Cause of Recurring Leaks
01

Identifying the Cause of Recurring Leaks

從密封唇磨耗、刮傷與變形痕跡,對照溝槽、配合面與工況,找出改善方向。

Select the jacket material based on operating conditions
02

Select the jacket material based on operating conditions

核對介質、溫度、磨耗與摩擦需求,挑出 PTFE 或其他高性能聚合物。

PRODUCT SELECTION

先確認密封用途,再配材料與尺寸

聚合物外套搭配內置金屬彈簧,彈簧為密封唇提供初始接觸力。

STEP 01

先確認你的密封用途

依壓力方向、配合面與運動條件分三種。

密封用途確認後再替外套與彈簧配材料
STEP 02

再替外套與彈簧配材料

外套與金屬彈簧分別確認,整理成可詢價的規格。
