It is short, maintenance, replacing part trouble.
The content of the invention
The invention aims to overcome the shortcoming of prior art, there is provided a kind of eccentric shaft installs steady, weares and teares little, no
Easy fracture, push-and-pull Plunger bearing motion stabilization, the plungers pump plunger perforation capacity eccentric bearing middle pushing mechanism of long service life.
The technical scheme of plungers pump plunger of the present invention perforation capacity eccentric bearing middle pushing mechanism is：Including the pump housing, the pump housing
Both sides connection cylinder body, the upper end of cylinder body installs drip chamber, and the lower end of cylinder body is installed intake chamber, plunger, plunger are installed in the pump housing
Driven by eccentric shaft, eccentric shaft is provided with balancing weight, it is characterised in that breach and perforation, the bias are set on described plunger
One of axle installs the first spring bearing through perforation in this end, and at the middle part of eccentric shaft push-and-pull plunger axis are installed
Hold, push-and-pull Plunger bearing is engaged with breach, the second spring bearing and reduction gearing are installed in another cephalic par of eccentric shaft, the
One spring bearing and the second spring bearing are arranged in the pump housing.
The capacity eccentric bearing middle pushing mechanism the invention discloses a kind of plungers pump plunger is bored a hole, sets on described plunger
Put breach and perforation, then by push-and-pull Plunger bearing（That is capacity eccentric bearing）Be arranged on the middle part of eccentric shaft, push-and-pull Plunger bearing with lack
Mouthful it is engaged, the first spring bearing and the second spring bearing are separately positioned on the both ends of eccentric shaft, install eccentric shaft more flat
Surely, during work, power drives reduction gearing, reduction gearing to drive eccentric shaft rotation, eccentric shaft to drive push-and-pull Plunger bearing to clash into
Breach wall, makes plunger front-rear reciprocation movement, having stable behavior, reliability, the impact of push-and-pull Plunger bearing bear in eccentric shaft
Middle part, eccentric shaft is not easy to wear, fracture, extends eccentric shaft service life, reduces maintenance, reduces cost.
The plungers pump plunger perforation capacity eccentric bearing middle pushing mechanism of the present invention, described plunger include front plunger rod and
Rear pillar stopper rod, connects plunger slide between forward and backward plunger rod, described breach and perforation is arranged in plunger slide, plunger by
Front plunger rod, rear pillar stopper rod and the part of plunger slide three composition, is easy to assembling.Two of described plunger slide is formed respectively with inserting
Head, is formed with groove on plug, front plunger rod and rear pillar stopper rod are made hollow, install oil seal strip in groove, oil seal strip with it is hollow
Front plunger rod and rear pillar stopper rod inwall are engaged, and good seal performance is easy to connect, firm.
