| 用于靜密封 大部分彈簧增強密封均可用于靜密封，其中103彈簧系列的更為合適，它提供中高等級的彈簧預(yù)緊力，可滿足大部分的靜密封要求。 | Radial Seal in Static Service While most of the DSH Spring Energized PTFE seals can be used as static radial seals, the DSH 103 is generally recommended for this service. It provides the middle-high grade spring pre-tightening force, can meet most of the static sealing requirements. |
| 用于往復(fù)密封 彈簧增強密封最常用的用途是用于往復(fù)運動密封。 對于中低壓的工況，建議使用400系列。這一系列產(chǎn)品采用低預(yù)緊力、高張角彈簧，磨耗低，壽命長，并可補償偏心。 APS系列采用簧絲彈簧，可提供幾乎恒定的彈簧預(yù)緊力，尺寸范圍廣。同時，如采用非常小的簧絲，適用于小尺寸、低摩擦值的要求。 | Radial Seals in Reciprocation Motion The most common applications of DSH Spring Energized Seals are reciprocating radial motion. For the medium-low pressure condition, it is recommended to use the 400 Series.The series of products adopt low pre-tightening force & higt angle spring, long service life, and can compensate the eccentric. APS Series adopt wire spring,which can provide almost constant force spring preload, widely size range. Meantime, if adopt small wire, will be cater to small size, low friction requirement. |
| 對于相對嚴(yán)格的往復(fù)密封，推薦使用103系列產(chǎn)品。這一系列產(chǎn)品采用高預(yù)緊力彈簧，能有效補償密封件的磨損，特別適合于中高壓的工況。 在400系列中采用耐久彈簧和楔型塊結(jié)構(gòu)，適用于重載和有長壽命要求的場合。 | For relatively strict reciprocating seal, 103 Series is recommended. This Series adopt high grade spring pre-tightening force spring, can effectively compensate the wear of seal, particularly suitable for middle-high pressure conditions. The 400 series adopts durable spring and wedge block structure, suitable for overloading and long life requirements of the occasion. |
| 用于旋轉(zhuǎn)密封 所有的彈簧增強密封均適用于低壓狀態(tài)下下的中低速旋轉(zhuǎn)密封和擺動密封。 對旋轉(zhuǎn)密封，推薦使用代號為PTW的端蓋式結(jié)構(gòu)。其密封件固有的安裝裙被壓緊在端蓋上，可防止密封件隨著軸的轉(zhuǎn)動而轉(zhuǎn)動。對于其它的結(jié)構(gòu)形式，由于溫度和其它因素的影響，這一情況是有可能發(fā)生的。 端蓋式結(jié)構(gòu)的APS和400彈簧系列適用于大部分的旋轉(zhuǎn)和擺動密封。在壓力低于0.1MPa、表面線速度1-1.5M/S的情況小，較小的彈簧預(yù)緊力有助于減少磨損。壓力較高時，要降低速度以利于延長壽命。 U形片狀彈簧結(jié)構(gòu)能補償少量的偏心。 對于高壓低速（＜0.25m/s）和間斷式旋轉(zhuǎn)、擺動密封，建議使用端蓋式結(jié)構(gòu)的103彈簧系列。 | Radial Seals in Rotaty Motion All of the DSHSpring Energized Seals designs are suitable for low pressure occasion in the middle-low speed rotating seal and swing seal. For swing seal, PTW is recommended. It will be tightly fixed on the end cover which can prevent seals from rotating while shaft rotating. For other structure forms, because of the temperature and other factors, this situation will possibly happen. End cover structure of the APS and 400 spring series is suitable for most of the rotation and swing seal. At the situation of pressure below 0.1MPa, surface speed 1-1.5M/S,spring with low pre-tightening force helps to reduce abrasion. At high pressure, to reduce the speed to help prolong life. U-shaped plate spring structure can compensate a bit eccentric. For high pressure low speed (< 0.25 m/s) and intermittent rotation, swing, recommend to use the end cover structure of 103 Series Spring. |
