Description
Technical field
The utility model belongs to plunger pump accessory technical field, more particularly, to a kind of new ceramics plunger.
Background technique
Plunger using more, and due to its special working environment, generally require special material.Previous plunger is all
It is to use specific alloy, but due to its higher cost, gradually replaced later by ceramic plunger.
Existing ceramic plunger often in metal plunger body outer surface coated ceramic layer, the fastness of this connection compared with
Difference, and since ceramic layer is relatively thin, it is also easily damaged, especially after using a period of time, due to heated, pressure, corrosion
Etc. factors, tend to loosen, fall off, and ceramics influenced vulnerable to external force it is damaged, it is therefore necessary to improved.
Summary of the invention
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of new ceramics plunger, it
The characteristics of good with wearability, intensity is high, and multi-buffer reduces stress to reduce abrasion, long service life.
To achieve the goals above, the technical scheme adopted by the utility model is a kind of new ceramics plunger, including column
Stopper rod and plunger bushing, the plunger bushing include upper round estrade and lateral body, diameter and side of the upper round estrade close to lateral body one end
Body diameter is equal, and diameter of the upper round estrade close to lateral body one end is greater than the diameter far from lateral body one end；The lateral body includes
First layer, the second layer, third layer, the 4th layer and layer 5, the first layer, third layer and layer 5 are all made of ceramics, described
The second layer and the 4th layer use wire.
Further, fixation hole is offered on the upper round estrade, further includes bolt and the plunger bushing through fixation hole,
The plunger rod includes the first body and the second body, and first body is equipped with bolt hole, the plunger lining far from one end of the second body
It puts on and offers first through hole, the screw bolt passes first through hole, fixation hole are connected with bolt hole.
Further, the upper round estrade is equipped with external annular groove and inner ring connected in star, the external annular groove and interior
Sealing bumper ring is equipped on annular groove.
Further, the plunger bushing includes upper body and lower body, and the first through hole includes upper first through hole and lower
One through-hole, the bolt include screw and nut, and the thickness of the upper first through hole is not less than the thickness of nut, and described upper first
The diameter of through-hole is not less than the diameter of nut, and the diameter of the lower first through hole is not more than the diameter of nut.
Further, first body is not less than the diameter of lower first through hole far from the overall diameter of second body one end.
After adopting the above structure, the utility model is compared to the prior art advantageously:
1. plunger bushing includes upper round estrade and lateral body, and the diameter of upper rotary table is less than lateral body diameter, carries out in plunger reciprocal
It is avoided that round estrade contacts the service life for reducing the upper round estrade of abrasion extension of upper round estrade with the pump housing when movement.
2. the intensity that the lateral body of plunger bushing by multi-layer ceramics and wire staggered, improves plunger bushing slow down ceramics by
The speed of external force breakage, at the same reduce production cost simultaneously ceramics itself have certain lubricating action can reduce making for butter
With further saving resource.
3. being equipped with multiplex buffer gear when plunger bushing and plunger rod are installed between plunger bushing and plunger rod avoids column
Plug sleeve and bolt and plunger rod directly contact that this avoid cause plunger bushing stress to fix when rotation bolt is fixed
Hole week along there is crack, extends the service life of plunger bushing.
4. the first through hole on plunger bushing is stepped, the nut on bolt can be preferably stored in this way, in this way in column
Plunger bushing contacts with the pump housing and avoids nut and directly contact with the pump housing when plug moves back and forth, and then avoids bolt and pump
The abrasion of the pump housing caused by body mutually touches, prolongs the service life.
Detailed description of the invention
Fig. 1 is the cross-sectional view of plunger bushing.
Fig. 2 is the cross-sectional view of plunger bushing.
Fig. 3 is the explosive view of the utility model.
Specific embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
It encloses, the present invention will be further described with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1 to Fig. 3: a kind of new ceramics plunger, including plunger rod 10 and plunger bushing 20, feature
Be: wherein plunger bushing 20 includes upper round estrade 21 and lateral body 22, wherein upper diameter and side of the round estrade 21 close to lateral body one end
The diameter that 22 diameter of body is equal and upper round estrade 21 is close to 22 one end of lateral body is greater than the diameter far from 22 one end of lateral body, in this way in column
Plug is avoided that round estrade 21 contacts the upper round estrade 21 of abrasion extension for reducing upper round estrade 21 with the pump housing when moving back and forth
Service life.Wherein lateral body 22 includes first layer 221, the second layer 222, third layer 223, the 4th layer 224 and layer 5 225,
And first layer 221, third layer 223 and layer 5 225 are all made of ceramics, the second layer 222 and the 4th layer 224 use wire, this
Sample multi-layer ceramics and wire, which are staggered, to be improved the intensity of plunger bushing 20 and slows down speed of the ceramics by external force breakage, is dropped simultaneously
The low production cost use that ceramics itself there is certain lubricating action can reduce butter simultaneously further saves resource.
Further, fixation hole 62 is offered on upper round estrade 21, further includes bolt 40 and the column through fixation hole 62
Bushing 30 is filled in, wherein plunger rod 10 includes the first body 11 and the second body 12, is equipped in the first body 11 far from one end of the second body 12
Bolt hole 63 offers first through hole 61 on plunger bushing 30, and wherein bolt 40 sequentially passes through first through hole 61, fixation hole 62
It is connected with bolt hole 63, so that plunger rod 10 and plunger bushing 20 are fixed to each other.
Further, external annular groove 211 and inner ring connected in star 212 are equipped on upper round estrade 21, in external annular groove
211 and inner ring connected in star 212 on be equipped with sealing bumper ring 50, can be reduced the company between plunger bushing 30, plunger bushing 20 in this way
Seam gap improves leakproofness in turn, avoids the hydrops in the gap that plunger bushing 20 and the connection of plunger rod 10 are formed.
Further, wherein plunger bushing 30 is rubber material, and wherein plunger bushing 30 includes upper body 31 and lower body 32,
Middle first through hole 61 includes upper first through hole 611 and lower first through hole 612, and wherein bolt 40 includes screw 41 and nut 42,
In upper first through hole 61 thickness L1 is not less than the thickness L2 of nut 42 and the diameter D1 of upper first through hole 61 is not less than nut 42
Diameter D2, so that bolt 40 avoids protruding when plunger rod 10 and plunger bushing 20 is fixed, and then avoids nut
42 when plunger moves back and forth bolt 40 be in contact with the pump housing pump housing caused to wear, wherein the diameter of lower first through hole 612
D3 is not more than the diameter D2 of nut 42, so that the connection wall card of nut 42 and lower first through hole 612 and upper first through hole 611
It connects.
Wherein the first body 11 is not less than the diameter D3 of lower first through hole 612 far from the overall diameter D4 of 12 one end of the second body, this
Sample abuts against plunger bushing 30 with plunger rod 10, and plunger rod 10 is avoided directly to be in contact with plunger bushing 20, reduces plunger bushing
20 stress further increase the service life of plunger bushing 20.
