Description
Technical field
The present invention relates to high voltage and constant current pump technical field more particularly to a kind of plunger rods of high pressure constant flow pump.
Background technique
High pressure constant flow pump uses the reciprocating twin columns stopper rod pumps in series head controlled by CPU, and plunger rod is its important group
At one of part, surface is not spray any wear-resistant material, due to often to replace plunger rod, the plunger rod work used
It is that comparison is severe as environment, lubrication circumstances are really poor, core component of the plunger rod as high pressure constant flow pump, and
Main motion parts, the regular abrasion of plunger rod bring serious influence to the normal use of high pressure constant flow pump.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of plunger rod of high pressure constant flow pump.
The present invention adopts the following technical scheme:
A kind of plunger rod of high pressure constant flow pump, including plunger bar body are provided with end cap in the plunger bar body, described
One end of plunger bar body is protruded into the end cap, offers several columns dovetail groove, institute along its circumferential direction in the plunger bar body
It states and is embedded with graphite block in dovetail groove, the one side of the graphite block is fixedly connected by fixed mechanism with the dovetail groove, another
Face is flushed with the periphery of the plunger bar body, and a support rod is provided at the center of the plunger rod body interior, described
It is connected between dovetail groove and the support rod using elastic cushion, the both ends of the elastic cushion and the dovetail groove and the support
Bar passes through anaerobic adhesive bonding connection.
Preferably, several lacunas are formed between the adjacent dovetail groove, are filled with carbon fiber in the lacuna.
Preferably, the outside of the plunger bar body is provided with axle sleeve, and one end of the graphite block extends to and the axis
The outer surface of set flushes.
Preferably, an interlayer is formed between the axle sleeve and the plunger bar body, is filled with carbon fiber in the interlayer.
Preferably, fixed mechanism is fixed screw, and the fixed screw is connected through a screw thread with the graphite block.
Preferably, the fixed screw is also made of graphite, and its end is flushed with the outer surface of the graphite block.
Preferably, the fixed screw is cross recess screw.
The invention has the following advantages: the plunger rod structural strength of high pressure constant flow pump of the invention is high, and in its circle
It is inlaid with graphite block on circumferential surface, has the function of self-lubricating, reduces the abrasion of plunger rod.
Detailed description of the invention
Preferred explanation is made to the present invention with reference to the accompanying drawing:
Fig. 1 is overall structure of the present invention;
Fig. 2 is structure of the invention fixed screw schematic diagram;
In the figure, it is marked as 1, plunger bar body;2, end cap;3, dovetail groove;4, support rod;5, elastic cushion;6, lacuna;7, axis
Set;8, interlayer;9, fixed screw.
Specific embodiment
It as shown in Figs. 1-2, is a kind of plunger rod of high pressure constant flow pump of the invention, including plunger bar body 1, plunger rod sheet
End cap 2 is provided on body 1, one end of plunger bar body 1 is protruded into end cap 2, is offered in plunger bar body 1 along its circumferential direction several
Column dovetail groove 3 is embedded with graphite block in dovetail groove 3, and the one side of graphite block is fixedly connected by fixed mechanism with dovetail groove 3, separately
It is flushed on one side with the periphery of plunger bar body 1, a support rod 4, dovetail groove 3 is provided at the center inside plunger bar body 1
It is connect between support rod 4 using elastic cushion 5, the both ends of elastic cushion 5 and dovetail groove 3 and support rod 4 pass through anaerobism glue sticking
Connection, when plunger bar body 1 is squeezed, can play buffer function.
Specifically, graphite block is embedded on the periphery of plunger bar body 1, in plunger rod sliding, due to graphite block
With self-lubricating function, lubrication can be played the role of in sliding, and be disposed in a dovetail groove 3, plunger is increased
The compression strength and non-deformability of bar.
Several lacunas 6 are formed between adjacent dovetail groove 3, are filled with carbon fiber in lacuna 6, are further increased plunger rod
Structural strength.
The outside of plunger bar body 1 is provided with axle sleeve 7, and one end of graphite block is extended to be flushed with the outer surface of axle sleeve 7.
An interlayer 8 is formed between axle sleeve 7 and plunger bar body 1, is filled with carbon fiber in interlayer 8.
Specifically, being provided with axle sleeve 7 in the outside of plunger rod, can play a protective role to plunger bar body 1.
Fixed mechanism is fixed screw 9, and fixed screw 9 is connected through a screw thread with graphite block, this detachable using screw
Fixed form, can be convenient and graphite block is replaced.
Fixed screw 9 is also made of graphite, and its end is flushed with the outer surface of graphite block, so that fixed screw 9
End face also has lubricating action.
Fixed screw 9 is cross recess screw, can be dismantled by screwdriver to it.
The above is only specific embodiments of the present invention, but technical characteristic of the invention is not limited thereto.It is any with this hair
Based on bright, to solve essentially identical technical problem, essentially identical technical effect is realized, made simple change, etc.
With replacement or modification etc., all it is covered by among protection scope of the present invention.
