PYI INC PSS軸密封
兩個2英寸無包密封系統軸密封 使我們能夠消除舊的傳統軸密封件，這些密封件不僅僅是繩索，而且油脂擠滿了和壓縮，但漏水的洩漏卻不斷緩慢。
PSS型A軸密封
對於3/4“至3-3/4” （20mm至95mm） 軸直徑
產品規格： PSS類型A密封尺寸下載： 安裝說明
A型PSS軸密封件是機械面密封。密封表面是在旋轉不銹鋼轉子的平坦表面和固定碳法蘭之間產生的。固定的碳法蘭用軟管夾連接到波紋管的前側，波紋管的後端安裝在船尾管上，並用軟管夾固定。不銹鋼轉子安裝在碳法蘭前的軸上。不銹鋼轉子在用固定的螺釘將轉子固定到軸上之前會壓縮波紋管。這種壓縮（預載）在不銹鋼轉子和碳法蘭的兩個平坦面之間保持恆定的接觸，從而使PSS可以補償由於推力螺旋槳推力而導致的可變前後運動。此外，碳法蘭對軸直徑過度填充，使其可以在軸上“漂浮”，從而補償大多數未對準和振動問題。不銹鋼轉子被兩個O形圈密封到軸上，嵌入了項圈的孔中。這些O形圈用軸和不銹鋼轉子旋轉，並且在操作過程中不會磨損。
溫度限制： 5°F至225°F（-15°C至107°C）
壓力極限： 15 psi（1 bar）
軸RPM極限： 10,000 rpm
碳石墨： 被綁定到4 HLB（0.000044“公差）
316S /氮50： 面對9-12 RA
波紋管材料： 模製氮 - PVC
它是如何工作的？
1 .兩個氮氣O形圈將不銹鋼轉子密封到軸上，不會磨損。
2. 主組螺釘和備用固定螺釘（2套）用於將不銹鋼轉子固定到軸上。
3. 在碳定子的兩個平面和不銹鋼轉子之間創建密封。
4. 水被饋入PSS軸密封件，以冷卻/潤滑高速容器上的密封面。
5. 固定的碳定子連接到硝酸捲曲龍，該硝基捲曲的附著在船尾管（軸原木）上。
成分
轉子
轉子由316升不銹鋼製成，並在精確的CNC車床上加工至9-12RA的飾面。它使用以90度角定位的2對固定螺釘將其固定在軸上，以實現最大的保持功率。不銹鋼轉子在操作的最初幾個小時內進一步拋光了碳定子。
碳定子
高密度，樹脂浸漬的碳定子是由先進的複合材料製成的，該複合材料首先混合和模製，然後在壓力下形成。然後將空白零件烘烤，加工，並將其拉開至4個氦燈帶的測量平坦度（在其整個額定表面上以0.000044”的變化為準）。PSS軸中使用的碳複合級等級具有最大的工作溫度與500°F（+260°C）的500°F（+260°C），如果密封在短時間內乾燥，與唇部密封或塑料臉部密封不同。此外，碳的高密度大大增加了壽命和耐磨性結果，在相同的原始組件上，有幾種商業船隻記錄了40,000多個發動機小時的40,000（超過4-1/2年的連續操作）。
波紋管
A型密封件上的波紋管是用氮化物模製的。硝化物以其對石油產品的良好耐藥性而聞名。此外，它提供了本應用所需的耐用性，強度和彈性的最佳組合。
軟管倒鉤
對於高速容器（12節以上），需要向PSS軸密封液置入正供水，以潤滑和冷卻密封面。請查看PSS軸密封安裝說明，以獲取有關供水點的更多信息。在大多數情況下，沒有帶有軸軸的慢速船（少於12節）不需要陽性的水進料，並且可以簡單地排出。理想情況下，通風線將在水線上方至少2-3英尺處運行，並儘可能靠近中心線。這將確保排氣軟管永遠不會低於水線，即使具有巨大的腳跟。 PSS軸密封安裝說明有更多有關發洩密封的詳細信息。
