Technical field
The present invention relates to a kind of plungers pump plunger perforation capacity eccentric bearing middle pushing mechanism, be mainly used in atomizing sprayer or washing machine plunger pump.
Background technique
At present, the plunger pump kind that atomizing sprayer is used or washing machine is used is more, wherein a kind of main structure comprises the pump housing, the both sides of the pump housing connect cylinder body, drip chamber is installed in the upper end of cylinder body, the lower end of cylinder body is installed into hydroecium, plunger is installed in the pump housing, plunger is driven by eccentric shaft, eccentric shaft is arranged in the pump housing by two spring bearings, on eccentric shaft, be equipped with reduction gear, on eccentric shaft, be equipped with push-and-pull Plunger bearing, on plunger, be shaped with breach, push-and-pull Plunger bearing is arranged in breach, the shortcoming of this structure is: a spring bearing in two spring bearings is arranged on one end of eccentric shaft, another spring bearing is arranged on the middle part of eccentric shaft, on eccentric shaft between two spring bearings, reduction gear is installed, push-and-pull Plunger bearing is installed on the other end of eccentric shaft, eccentric shaft is installed not steady, wearing and tearing are large, clash in plunger process at push-and-pull Plunger bearing, easily cause eccentric shaft fracture, working life is short, maintenance, replacing parts trouble.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, provide a kind of eccentric shaft to install steadily, wear and tear little, not easy-rupturing, push-and-pull Plunger bearing motion stabilization, the plungers pump plunger perforation capacity eccentric bearing middle pushing mechanism of long service life.
The technological scheme of plungers pump plunger perforation capacity eccentric bearing middle pushing mechanism of the present invention is: comprise the pump housing, the both sides of the pump housing connect cylinder body, drip chamber is installed in the upper end of cylinder body, the lower end of cylinder body is installed into hydroecium, plunger is installed in the pump housing, plunger is driven by eccentric shaft, eccentric shaft is provided with balancing weight, it is characterized in that, on described plunger, breach and perforation are set, one of described eccentric shaft through perforation, and in this end, the first spring bearing is installed, push-and-pull Plunger bearing is installed at middle part at eccentric shaft, push-and-pull Plunger bearing matches with breach, the second spring bearing and reduction gear are installed in end, other end at eccentric shaft, the first spring bearing and the second spring bearing are arranged in the pump housing.
The invention discloses a kind of plungers pump plunger perforation capacity eccentric bearing middle pushing mechanism, breach and perforation are set on described plunger, again push-and-pull Plunger bearing (being capacity eccentric bearing) is arranged on to the middle part of eccentric shaft, push-and-pull Plunger bearing matches with breach, the first spring bearing and the second spring bearing are separately positioned on the two end part of eccentric shaft, eccentric shaft is installed more steady, when work, power drives reduction gear, reduction gear drives eccentric shaft rotation, eccentric shaft drives push-and-pull Plunger bearing to clash into breach wall, make plunger front-rear reciprocation movement, having stable behavior, reliably, the impact force of push-and-pull Plunger bearing is born the middle part at eccentric shaft, eccentric shaft is not easy to wear, fracture, extend eccentric shaft working life, reduce maintenance, reduce costs.
Plungers pump plunger perforation capacity eccentric bearing middle pushing mechanism of the present invention, described plunger comprises front plunger rod and rear pillar stopper rod, between forward and backward plunger rod, connect plunger slide, described breach and perforation are arranged in plunger slide, plunger is made up of front plunger rod, rear pillar stopper rod and plunger slide three parts, is convenient to assembling.Two of described plunger slide is shaped with respectively plug, is shaped with groove on plug, and front plunger rod and rear pillar stopper rod are made hollow, oil seal strip is installed in groove, oil seal strip matches with front plunger rod and the rear pillar stopper rod inwall of hollow, and good seal performance is easy to connect, firm.
