Embodiment
As shown in Figure 1.
High-pressure airless pump seal structure, by: ball head column stopper rod 1, plunger rod spiral shell seat 2, felt 3, packing ring 4, seal ring A5, spring washer 6, seal ring B7, seal ring C8, plunger rod locating pad 9, combination back-up ring 10, seal ring D11 are formed.
A kind of high-pressure airless pump seal structure, comprise: ball head column stopper rod 1, plunger rod spiral shell seat 2, between ball head column stopper rod 1, plunger rod spiral shell seat 2, be provided with double sealing structure, described double sealing structure is made of primary seal structure and time sealing configuration, the primary seal structure is installed in the cavity between ball head column stopper rod 1, the plunger rod spiral shell seat 2, inferior sealing configuration is installed on the lower position of primary seal structure, is provided with plunger rod locating pad 9 between primary seal structure and time sealing configuration.
The primary seal structure comprises: packing ring 4, seal ring A5, spring washer 6, seal ring B7, two folder cloth seal ring A5 and three plastic seal ring B7 constitute V-type skeleton packing composite structure, be provided with copper packing ring 4 and wavy spring packing ring 6, two folders cloth seal ring A5 and three plastic seal ring B7 at the two ends of two folders cloth seal ring A5 and three plastic seal ring B7 and under the supporting of copper packing ring 4 and wavy spring packing ring 6 and packing fixation, form sealing configuration.
A folder cloth seal ring A5 is set between per two plastic seal ring B7, and two folder cloth seal ring A5 are state setting spaced apart mutually with three plastic seal ring B7, and stack constitutes the packing composite structure mutually.
Inferior sealing configuration comprises: combination back-up ring 10, seal ring D11, seal ring D11 are set on the water jacket of combination back-up ring 10, can make combination back-up ring 10 hold ball head column stopper rod 1 all the time tightly after seal ring D11 assembling compresses and form sealing configuration.
Packing ring 4 is the copper material packing ring, and seal ring A5, seal ring B7 are the V-shaped seal ring structure, and spring washer 6 is the wave spring washer, and seal ring C8, seal ring D11 are the O RunddichtringO, and combination back-up ring 10 is a L type elastic seal ring.
Plunger rod spiral shell seat 2 effect is various seal rings are installed and are fixed with the pump housing, felt 3 effects are that storage lubricant oil provides lubrication for ball head column stopper rod 1, copper packing ring 4 is with combination V-type circle with the effect of spring washer 6, be seal ring A5, the effect of supporting and packing V-type circle is played at seal ring B7 part two ends, use sealing to produce effect more, the effect of plunger rod locating pad 9 is with seal ring A5, the V-type circle sealing of seal ring B7 seals with following combination back-up ring 10 and separates, form the master of two combinations, inferior sealing configuration, the effect of inferior sealing configuration that combination back-up ring 10 and O RunddichtringO D11 are combined to form is that formation first road is sealed in front end and blocks coating, make paint particles be difficult for entering primary seal
Form the first passage sealing configuration by combination back-up ring 10 with O RunddichtringO D11 group and block coating, O RunddichtringO D11 is an energy-storage travelling wave tube under compression, it is enclosed within and can makes combination back-up ring 10 embrace ball head column stopper rod formation primary seal all the time on the water jacket that makes up back-up ring 10 after the compression, forming the V-type packing by the plastic seal ring B7 skeleton of two folders cloth seal ring A5 and three whites is combined in copper packing ring 4 and wavy spring packing ring 6 two ends and fixes and time form primary seal, well coating is blocked, this sealing configuration is simple, and the life-span is long.
Check before installing that each part must be clean, foreign material such as no burr are installed fore-clamp cloth rubber seal A5 and were soaked in lubricant oil 5 minutes, and each O-ring seals outer surface is coated with an amount of butter, in case hurt outer surface when packing into, with instrument each part are in place.
During high-pressure airless pump seal arrangement works, ball head column stopper rod 1 is done axial motion in plunger cavity, suction pressure paint, coating, since ball head column stopper rod 1 in plunger cavity and paint, coating directly contacts, so paint, coating can be bonded on ball head column stopper rod 1 surface, when ball head column stopper rod 1 aspirates paint repeatedly, during coating, sticking to ball head column stopper rod 1 surface paints, coating just may enter ball head column stopper rod 1, in the movement clearance between the plunger rod spiral shell seat 2, can influence the usability of high-pressure airless pump like this, so after having adopted double sealing structure, when ball head column stopper rod 1 suction paint, during coating, stick to ball head column stopper rod 1 surface and go up greatly part paint, coating is at first by the combination back-up ring 10 of inferior sealing configuration, seal ring D11 stops, make paint particles be difficult for entering in the primary seal, so just guaranteed the complete sealability of primary seal, as there is not first a road barrier effect of inferior sealing configuration, only use single primary seal structure to seal, then be difficult to guarantee paint, coating can not enter ball head column stopper rod 1, in the movement clearance between the plunger rod spiral shell seat 2, adopt main now, behind the inferior double sealing structure, even trace paint is arranged, coating enters in the primary seal by inferior sealing configuration, because the seal action again of primary seal structure, just can stop paint fully, coating enters ball head column stopper rod 1, in the movement clearance between the plunger rod spiral shell seat 2, guarantee the good operation of high-pressure airless pump, improved working life.
