Part.One end of the secondary letter body 9 is provided with pressure cap 14, and the pressure cap 14 is between the secondary letter body 9 and the plunger 10 and institute
Pressure cap 14 is stated to be against on the seal member.The positive stop lug boss of the ring-type extended to plunger 10 is provided with secondary letter body 9, pressure cap 14 will
Seal member is held out against on positive stop lug boss, and seal member ensure that the sealing in the reciprocatory movement of plunger 10, avoid sewage
Leak, effectively reduce the labor intensity of worker.The seal member includes 11 two kinds of V-shaped seal ring 12 and y-type seal ring
One or both of sealing ring, during from V-shaped seal ring, the support ring of V-shaped seal ring closes on the pressure cap 14, V-seal
The pushing out ring of circle is then away from the pressure cap 14；Then its outer lip and interior lip are located remotely from the pressure cap 14 during from y-type seal ring
One end.It is preferred that setting V-shaped seal ring 12 and y-type seal ring 11 arranged side by side.The V-shaped seal ring and the y-type seal ring
Notch is set away from the pressure cap 14, avoids greasy dirt from leaking.When setting V-shaped seal ring and y-type seal ring simultaneously, the pressure
Cap 14 is against on the V-shaped seal ring 12.
Due to being contacted between pressure cap 14 and seal member and plunger 10, when plunger 10 moves back and forth, pressure cap 14, sealing
Frictional resistance between part and plunger 10 not only causes the efficiency of motor to reduce, while also causes pressure cap 14, seal member and post
Fill in 10 easy to wear, therefore, in order to reduce the frictional resistance between pressure cap 14, seal member and plunger 10, set in the pressure cap 14
