With the life-span, good seal performance, the purpose of long service life are reached；
3) the direction spinfunction of universal spheroid, makes sealer integrally can swing 10 ° -20 ° in 360 ° of any directions, realizes
Automatic radial direction tuningout centering with polished rod, solves eccentric wear load wear and increases, greatly reduce pumping unit load, economize on
Electricity 20% about；
4) bottom two ends intersection dislocation seal, plus the high intensity anti-wear sheath at the upper and lower two of packing forms multi-stage sealed
Chain, high pressure resistant so that polished rod is not contacted up to 25mpa, any metallic object avoid polished rod abrasion；
5) sealer bottom design two transverse translation formula, leading portion intersection airtight combination, only need to can be manually rotated hand
Wheel, you can seal well head, changes top packing, and dependable performance is simple to operate.
6) tight lock handle manually, is not required to pipe wrench, greatly reduces the labour intensity of mining facilities, can save the time,
Improve efficiency.
