Abstract
The utility model discloses a plunger, four platforms have been offered outward on the disc to the plunger cover of being connected including the plunger pole, with the plunger pole, plunger pole, the outer uniform distribution of plunger pole is followed to the platform, still be provided with the oil groove on the plunger pole, the utility model has the advantages of simple and compact structure and equitable, convenient assembling is swift, connect reliably, offer oil groove and platform through adopting on the plunger pole, produce the friction with the plunger cover when having reduced the plunger pole and being piston motion, avoided plunger fracture and lubricated incomplete phenomenon, lengthened plunger life, improved the reliability that plunger worked greatly, easily use widely.
Description
Technical field
This utility model relates to the accessory on a kind of plunger displacement pump, is specifically related in flush coater technical field be assemblied in plunger displacement pump
Interior a kind of plunger.
Background technology
Plunger is part important in pump, and the quality height of pump, performance are the most stably often depending on the quality of plunger.Existing
What some plungers were taked is the mode oil-feed cutting into hydraulic fluid port at plunger guide, and the mode of this oil-feed has the disadvantage in that post
Stopper rod moves to incision when of doing piston movement and plunger bushing produces friction；The post of major diameter selected by powerful flush coater
Plug, in order to ensure that machine is normal, the otch of plunger bushing will be accomplished enough big, but the when of so causing assembling, plunger is led
Set is easy to rupture from incision；Original plunger and plunger guide are the contact surfaces of whole circle, and such plunger motion is rubbed relatively
Wipe force rate bigger.
Utility model content
This utility model devises a kind of plunger to solve the problems referred to above, its object is to: provide a kind of mar proof
Good, perfect heat-dissipating, the plunger of length in service life.
This utility model technical solution:
A kind of plunger, the plunger bushing being connected with plunger rod including plunger rod, it is characterised in that: open on plunger rod periphery
Being provided with four platforms, described platform is uniformly distributed along plunger rod outer surface, and described plunger rod is additionally provided with oil groove.
Described platform is arranged at distance post stopper rod upper surface 1/3.
Described platform is 0.5～2mm away from plunger rod periphery distance.
Described oil groove has 4～8, and oil groove is circumferentially distributed along plunger rod.
The beneficial effects of the utility model:
This utility model simple in construction, compact and reasonable, easy to assembly fast connect reliable, by using at plunger
Offer oil groove and platform on bar, reduce and produce friction with plunger bushing when plunger rod does piston movement, it is to avoid plunger fracture with
And lubricate incomplete phenomenon, extend plunger service life, substantially increase the reliability of plunger work, it is easy to promote the use of.
Accompanying drawing explanation
Fig. 1: this utility model structural representation.
Wherein: plunger rod 1, plunger bushing 2, oil groove 3, platform 4.
Detailed description of the invention
This utility model is illustrated below in conjunction with accompanying drawing.
As it is shown in figure 1, a kind of plunger, mainly it is made up of plunger rod 1 and plunger bushing 2.Four are offered on plunger rod 1 periphery
Individual platform 4, described platform 4 is uniformly distributed along plunger rod 1 outer surface, and described plunger rod 1 is additionally provided with oil groove 3, described platform 4
Being arranged at distance post stopper rod 1 upper surface 1/3, described platform 4 is 0.5～2mm away from plunger rod 1 periphery distance, described oil groove 3
Having 4～8, oil groove 3 is circumferentially distributed along plunger rod 1.
Uniformly offer four platforms on plunger rod periphery, and platform be 0.5～2mm away from plunger rod periphery distance,
So can reduce contact area between plunger rod and plunger bushing, reduce and rub, on plunger rod between plunger rod and plunger bushing
Oil circuit can ensure that plunger rod obtains sufficient lubrication, and this utility model, owing to using technique scheme, not only increases plunger
Service life, and installing/dismounting is more convenient.
To sum up, this utility model accomplishes the end in view.
