HM18

详细说明

Design Features：

n Specially designed engineering seal；

n Multi-spring, balanced structure, static design；

n The primary ring and mating ring structures of the seal friction pair designed by finite element optimization can effectively control the thermal and mechanical deformation of the seal under high pressure；

n The primary ring and mating ring of the whole structure are floating mounted in the sealing ring holders, so that the deformation of the primary ring and mating ring caused by medium pressure is less；

n Solid and reliable primary ring transmission and mating ring anti-rotation structure design can improve the seal's capacity against being hung-up；

n Special spring layout design makes the spring force acting on the sealing surface more uniform；

n Evenly distributed flushing arrangement is adopted to make the sealing temperature distribution more uniform and the thermal deformation less；

n Single seal and double seal arrangements are available；

n Using the latest silicon carbide composite material versus silicon carbide as friction pair, can further improve the sealing pressure range；

n Adopt integral assembly structure, easy to install and disassemble.
