Description
Technical field
The present invention relates to a kind of bittern purifying production pipeline vibration cancelling arrangements, more particularly, to a kind of elimination pipe vibration
Device and method.
Background technique
Currently, during bittern purifying spoil disposal, the piston of three cylinder single-acting plunger type slush pumps each cylinder at runtime
Intermittent successively work done, the medium that when work done is discharged generate percussion to pipeline, cause pipe vibration larger and obvious, even
The tee tube weld seam welded in pipeline is shattered, valve flanges fastening bolt shakes loose, and causes maintenance frequently and heavy workload；Together
When, bittern purifying sludge discharge work is caused to seriously affect.
201757245 U of CN discloses a kind of buffer unit for main delivery pump of slurry pipeline, and the main pump is in main pump
There are No.1 entrance valve chamber, No. two entrance valve chambers and No. three entrance valve chambers in serially connected distribution, in master on entrance main pipeline
Pump intake pipe end has main pump inlet pipe stopper, and buffer unit includes surge tank and surge tank diaphragm, is filled in surge tank
There is nitrogen, which is arranged at the main pump inlet pipe stopper, for compensating the suction pressure of No. three entrance valve chambers.It should
Buffer unit mainly solves the problems, such as that three entrance valve type suction pressures of main pump are non-uniform, not can solve asking for pipe vibration
Topic.
203880400 U of CN discloses a kind of system for reducing reciprocating pump pipe vibration, including feed liquid storage tank and reciprocal
The suction inlet pipeline of pump, feed liquid storage tank and reciprocating pump connects, and feed liquid is delivered to throwing by pipeline by the outlet of the reciprocating pump
Shots, be also communicated on the pipeline of the reciprocal pump discharge feed liquid storage tank described in pulse damper also pass through bypass duct with it is past
The pipeline of multiple pump discharge is connected, the bypass duct, reciprocal pump discharge pipeline tie point be located at pulse damper and
Between reciprocating pump, safety valve is also equipped on bypass duct.The system that the prosperous husband of the reduction pumps pipe vibration passes through safety valve, back pressure
Valve and pulse damper eliminate the fluid pulse in pipeline, reduce pressure oscillation, and then reduce pipe vibration amplitude, but not applicable
In the bittern purifying pipeline of three cylinder single-acting plunger type slush pumps.
In addition, three cylinder single-acting plunger type slush pump manufacturers can make pipeline impact to solve pump in work done
The problem of pipe vibration, is equipped with buffer air packet in pump head outlet port, and then reduces pump in work done to the impact of pipeline.
But the mud pumpage of bittern purifying production is larger, and existing buffer air packet is less than normal and cannot eliminate slush pump in work done
Impact to pipeline, the vibration that pipeline impact is generated when eliminating piston work done, it is necessary to which a volume is relatively large slow
Rush air packet, but there is also pump head outlet port can not the big buffer air packet of installation volume, bulky buffer air packet
Processing and fabricating cost it is high.
Pipe vibration when in order to solve the problems, such as bittern purifying spoil disposal needs a kind of elimination pipe easy to operate, at low cost
The device and method of road vibration, and then extenuate and eliminate the oscillation phenomenon of pipeline.
Summary of the invention
The technical problem to be solved by the present invention is overcoming the deficiencies of the prior art and provide, a kind of structure is simple, cost of manufacture
It is low, the device and method easy to use for eliminating pipe vibration.
The technical solution adopted by the present invention to solve the technical problems is:
