Description
Technical field
The utility model relates to plunger pump fields, and in particular to a kind of ceramic plunger that stability is high.
Background technique
Existing plunger using more, and due to its special working environment, generally require special material.In the past
Plunger is all to use specific alloy, but due to its higher cost, gradually replaced later by ceramic plunger.It includes metal column
Plug body, structure are inlaid in ceramic tube in metal plunger body outer surface coated ceramic layer or by metal plunger ontology.
The wearability of this plunger is preferable, and service life is also longer, and production cost is relatively low.But metal plunger ontology is inlaid in pottery
The ceramic plunger produced in porcelain tube is under prolonged use, since factors, the plunger bushings such as heated, pressure, corrosion are often steady
Qualitative poor, to lead to the problem of, easy loosening, fall off generation.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of ceramics poles that stability is high
Plug.
To achieve the above object, the utility model provides following technical solution: including plunger rod and being set in plunger rod
On plunger bushing, plunger bushing is equipped with ceramic layer, and also opposite on plunger rod to be equipped with the first fixed column and the second fixed column, first is solid
Fixed column and the second fixed column are equipped with limiting device, and limiting device includes the limit in the first fixed column and the second fixed column
Hole, limit hole is interior to be equipped with spring and ball;
Plunger bushing is equipped with positioning device, and positioning device includes the shifting chute and locating slot being connected, and shifting chute includes the
One shifting chute and the second shifting chute, first movement slot and the first fixed column match, the second shifting chute and the second fixed column phase
Match, locating slot includes the first locating slot and the second locating slot, and the first locating slot is connected with first movement slot, the second locating slot and
Second shifting chute is connected, and location hole compatible with ball is equipped in the first locating slot and the second locating slot.
Further, it is additionally provided with fixation hole on plunger bushing, sealing rubber layer is equipped in fixation hole, is equipped in fixation hole by plunger
The screw that bar is fixedly connected with plunger bushing.
Further, it is additionally provided with dashpot on plunger rod, is equipped with buffering ring in dashpot.
The deficiencies in the prior art are compared, the utility model has the advantages that when in use brought by technical solution provided by the utility model,
Plunger rod is protruded into plunger bushing, the first fixed column and the second fixed column are located at first movement slot and the second shifting chute at this time
It is interior, plunger rod is pushed, so that plunger rod moves in the vertical direction, and when plunger rod is moved to suitable position, column spinner stopper rod,
So that the first fixed column and the second fixed column are respectively moved in the first locating slot and the second locating slot, therefore when in use, the
The presence of one fixed column and the second fixed column makes it possible in the horizontal direction play plunger bushing fixed effect, while location hole
Presence but also the vibration that the first fixed link and the second fixed link generate when will not be because of work, and occur in the horizontal direction
Displacement, avoids the problem of plunger bushing falls off from plunger rod, so that the stability of ceramic plunger is higher, while spring
In the presence of also can play a buffer role in, when plunger bushing shakes, it can effectively alleviate vibration amplitude, avoiding plunger bushing and column
Stopper rod collides and causes the problem of wearing.
Detailed description of the invention
Fig. 1 is the plunger rod cross-sectional view of the utility model.
Fig. 2 is the plunger bushing cross-sectional view of the utility model.
Fig. 3 is the plunger bushing schematic diagram of internal structure of the utility model.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be merely to illustrate and explain the present invention, is not used to limit the utility model.
- Fig. 3 is described further the utility model referring to Fig.1.
A kind of ceramic plunger that stability is high, including plunger rod 1 and the plunger bushing 2 being set on plunger rod 1, plunger bushing 2
It is equipped with ceramic layer, is also equipped with the first fixed column 11 and the second fixed column 12, the first fixed column 11 and second relatively on plunger rod 1
Fixed column 12 is equipped with limiting device, and limiting device includes the limit hole in the first fixed column 11 and the second fixed column 12,
Spring 13 and ball 14 are equipped in limit hole;
Plunger bushing 2 is equipped with positioning device, and positioning device includes the shifting chute and locating slot being connected, and shifting chute includes the
One shifting chute 21 and the second shifting chute 22, first movement slot 21 and the first fixed column 11 match, the second shifting chute 22 and second
Fixed column 12 matches, and locating slot includes the first locating slot 211 and the second locating slot, the first locating slot 211 and first movement slot
21 are connected, and the second locating slot and the second shifting chute 22 are connected, and are equipped in the first locating slot 211 and the second locating slot and ball
Compatible location hole 212;When in use, plunger rod 1 is protruded into plunger bushing 2, the first fixed column 11 and second is fixed at this time
Column 12 is located in first movement slot 21 and the second shifting chute 22, plunger rod 1 is pushed, so that plunger rod 1 is in the vertical direction
It is mobile, when plunger rod 1 is moved to suitable position, column spinner stopper rod 1, so that the first fixed column 11 and the second fixed column 12 difference
It is moved in the first locating slot 211 and the second locating slot, therefore when in use, the first fixed column 11 and the second fixed column 12 are deposited
Making it possible in the horizontal direction play plunger bushing 2 fixed effect, while the presence of location hole 212 is but also first is fixed
The vibration that bar 11 and the second fixed link 12 generate when will not be because of work, and be subjected to displacement in the horizontal direction, avoid plunger
The problem of set 2 falls off from plunger rod 1, so that the stability of ceramic plunger is higher, while the presence of spring 13 can also rise
Vibration amplitude can effectively be alleviated when plunger bushing 2 shakes to buffer function, plunger bushing 2 and plunger rod 1 is avoided to send out
Life collides and causes the problem of wearing;The presence of ball 14 is but also the first fixed link 11 and the second fixed link 12 exist simultaneously
It is more laborsaving when being moved in shifting chute and locating slot, so that installation is more convenient, improve installation effectiveness.
Further, it is additionally provided with fixation hole 23 on plunger bushing 2, is equipped with sealing rubber layer 24 in fixation hole 23, in fixation hole 23
Equipped with the screw for being fixedly connected with plunger rod 1 with plunger bushing 2, by screw fixed column plug sleeve 2 and plunger rod 1, so that plunger bushing 2
It is higher with the stability of plunger rod 1, while the presence of fixation hole 23 protrude from screw will not outside plunger bushing 2, seal simultaneously
The presence of rubber layer 24 to prevent the impurity such as extraneous clast to enter at work so that plunger bushing 2 and plunger rod 1 it
Between will not because of impurity entrance and generate abrasion, extend the service life of plunger, at the same also can effectively alleviate because shake
The problem of moving and screw caused to fall off.
Further, it is additionally provided with dashpot on plunger rod 1, is equipped with buffering ring 15 in dashpot, the presence of buffering ring 15 makes
Combination between plunger rod 1 and plunger bushing 2 more closely avoids foreign matter from entering, but also when plunger bushing 2 shakes,
Vibration can effectively be alleviated, and avoid the problem that plunger bushing 2 and plunger rod 1 occur direct collision and wear aggravation to caused by
Occur.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
