摘要： An improved mechanical face seal is provided which includes a pair of relatively rotatable seal rings having opposing seal faces. At least one of the seal faces includes a reverse trapezoidal face pattern having a sine wave depth profile wherein individual face features are circumferentially spaced over the seal face. The reverse trapezoidal face pattern serves to generate a hydrodynamic lift which provides a stable separation of the seal faces that permits formation of a fluid film between the seal faces. The individual trapezoidal grooves have a sinusoidal or similarly shaped depth profile wherein the trapezoid shape is arranged with the narrower edge communicating with the high pressure side of the seal, and the wider edge forms a circumferential dam region towards the low pressure side of the seal. Alternatively, the reverse trapezoidal face pattern may also be provided as a primary face pattern on a dry gas seal in combination with a secondary face pattern wherein the faces operate with a controlled gap under normal pressure conditions as well as when the pressure direction across the seal face is reversed.

摘要： An improved mechanical face seal is provided which includes a pair of relatively rotatable seal rings having opposing seal faces. At least one of the seal faces (72) includes a reverse trapezoidal face pattern (75) having a sine wave depth profile wherein individual face features are circumferentially spaced over the seal face (72). The reverse trapezoidal face pattern (75) serves to generate a hydrodynamic lift which provides a stable separation of the seal faces that permits formation of a fluid film between the seal faces. The individual trapezoidal grooves (76) have a sinusoidal or similarly shaped depth profile wherein the trapezoid shape is arranged with the narrower edge (78) communicating with the high pressure side of the seal, and the wider edge (79) forms a circumferential dam region (81) towards the low pressure side of the seal. Alternatively, the reverse trapezoidal face pattern may also be provided as a primary face pattern on a dry gas seal in combination with a secondary face pattern wherein the faces operate with a controlled gap under normal pressure conditions as well as when the pressure direction across the seal face is reversed.
摘要翻译：提供了一种改进的机械面密封件，其包括一对具有相对的密封面的相对可旋转的密封环。至少一个密封面（72）包括具有正弦波深度轮廓的反向梯形面部图案（75），其中各个面部特征在密封面（72）上周向间隔开。反向梯形面图案（75）用于产生流体动力提升，其提供允许在密封面之间形成流体膜的密封面的稳定分离。各个梯形槽（76）具有正弦形状或类似形状的深度轮廓，其中梯形形状布置有较窄边缘（78）与密封件的高压侧连通，并且较宽边缘（79）形成周向坝区（81）朝向密封件的低压侧。或者，反向梯形面部图案也可以作为初级面部图案设置在干燥气体密封件上，与次要面部图案相组合，其中在正常压力条件下以及当密封件的压力方向脸倒转

摘要： A bearing isolator seal (10) includes a rotor (23) and stator (24) wherein the stator (24) has inboard (26) and outboard (32) radial projections which define a groove (34) bounded by groove side faces (36, 37) and a groove bottom face (38). The rotor (23) extends radially (35) and then axially (36) so as to lie closely adjacent to the terminal end (33) of the outboard radial projection (32) on the stator (24) to define an entrance passageway (39). The bearing isolator seal (10) includes a surface geometry which is believed to result in improved exclusion of contaminants, particularly from high velocity water spray, wherein the entrance passageway (39) is angled to increase the rotational effects of exclusion during shaft (12) rotation, and wherein the groove side faces (36, 37) are also angled (38A, 38B) to assist in redirecting spray and other contaminants away from the passageway (39).
