PUMP SEAL

An annular seal for sealing an opening in a pump housing surrounding a piston rod includes a primary sealing portion with an inner surface adjacent to the piston rod and an outer surface adjacent to the pump housing. An initial sealing portion features an inner wall and an outer wall so that an annu...

description	An annular seal for sealing an opening in a pump housing surrounding a piston rod includes a primary sealing portion with an inner surface adjacent to the piston rod and an outer surface adjacent to the pump housing. An initial sealing portion features an inner wall and an outer wall so that an annular space is defined therebetween. A top wall extends between the inner and outer walls. A coil spring is positioned within the annular space of the initial sealing portion and urges the inner wall into engagement with the piston rod and the outer wall into engagement with the pump housing. 一种用于密封围绕活塞杆的泵壳体中的开口的环形密封件包括主密封部分，其具有邻近活塞杆的内表面和邻近泵壳体的外表面。初始密封部分具有内壁和外壁，使得在内壁和外壁之间限定环形空间。顶壁在内壁和外壁之间延伸。螺旋弹簧位于初始密封部分的环形空间内，并且促使内壁与活塞杆接合且外壁与泵壳体接合。
