Abstract
Impulse-eliminator using travelling wave tube belongs to liquid flow pipeline damper technology.Be the improvement of feed-through fluid pulse vibration absorber, cancelled air chamber, increased quality---spring system, do not need inflation, do not have the shortcoming that causes owing to inflation.
Description
The invention belongs to liquid flow pipeline damper technology.
In recent years, aspect the weakening of reciprocating pump fluid pipe, the factory that has has adopted this new technology of feed-through fluid pulse vibration absorber (Chen Shouwu, Huang Youling, Cai Zebiao: the mechanism research of feed-through fluid pulse vibration absorber, XI AN JIAOTONG UNIVERSITY Subject Index, the 18th volume, the 1st phase, 1-8 page or leaf, in February, 1984).This kind vibration absorber has an air chamber, needs inflation, needs source of the gas and charger, frequent air feed; Require the body of inflating and working liquid body chemical reaction does not take place, and gas does not influence technological process after sneaking into liquid.
The objective of the invention is to overcome the shortcoming of feed-through fluid pulse vibration absorber, non-inflatable just weakening effectively.
Main body cover of the present invention is a circular cylinder body, and working liquid body flows into from the one end, flows out from the other end.There is a circular hole in central authorities in the inlet end face of cylindrical shell, have a travelling wave valve to pass this circular hole, and the external diameter of travelling wave valve is identical with Circularhole diameter, and travelling wave valve and cylindrical shell weld together.Travelling wave valve is made of a perforated tube and a pipe end orifice plate.The diameter of perforated tube is identical with the main flow pipeline, and its part is beyond cylindrical shell, and the end outside cylindrical shell leads to by the main flow pipeline of suction flange and import; Another part of perforated tube has many apertures on the tube wall of cylindrical shell with interior part in cylindrical shell, an end and pipe end orifice plate in the cylindrical shell weld together, and there is a small sircle hole in the central authorities of pipe end orifice plate.There is an exit orifice in exit end face central authorities at cylindrical shell, and cylindrical shell leads at an end of an exit orifice place and an outer pipe, and both weld together, and the other end of outer pipe leads to by the main flow pipeline of outlet(discharge) flange with outlet.Between the flange on flange on the outer pipe and the outlet main flow pipeline, an outlet orifice plate can be arranged, there is a small sircle hole in its central authorities.
Near the exit orifice place a quality-spring system is arranged in cylindrical shell, it constitutes (in case of necessity guide rod can be arranged) by a screen stream plate and two springs, and the two ends of each root spring are connected with body end surface with screen stream plate respectively.On the screen stream plate two circular through flow holes are arranged.
The present invention is connected on the reciprocating pump liquid stream main pipe, can obviously reduces Analysis of Pipe Vibrations.Prolong the working life of pipeline, energy saving, and can alleviate noise pollution, increase staff's the sense of security.
Impulse-eliminator using travelling wave tube can be horizontal (Fig. 1), also can be vertical (Fig. 2).On the screen stream plate of horizontal impulse-eliminator using travelling wave tube two pilot holes are arranged, spring is a coil spring, is fixing two guide rods on cylindrical shell outlet end inwall, and guide rod passes coil spring and pilot hole, screen stream plate is play the guiding role, and coil spring is played a supportive role.The spring of vertical impulse-eliminator using travelling wave tube can be a leaf spring, also can be the coil spring that has guide rod, on the screen stream plate two pilot holes is arranged also simultaneously.
Description of drawings Fig. 1 is horizontal impulse-eliminator using travelling wave tube, and Fig. 2 is vertical impulse-eliminator using travelling wave tube, and Fig. 3 is the screen stream plate that has pilot hole.1 is suction flange among the figure, the 2nd, and cylindrical shell, the 3rd, perforated tube, the 4th, aperture, the 5th, pipe end orifice plate, the 6th, screen stream plate, the 7th, outer pipe, the 8th, outlet(discharge) flange, the 9th, outlet orifice plate, the 10th, guide rod, the 11st, coil spring, the 12nd, leaf spring, the 13rd, through flow hole, the 14th, pilot hole, L are the length of cylindrical shell, D is the internal diameter of cylindrical shell, and d is the internal diameter of main flow pipeline, D
1Be the diameter of screen stream plate, d
1It is the diameter of through flow hole.
When enforcement is of the present invention, should determine the inner diameter d of main flow pipeline earlier according to its concrete purposes, select the physical dimension of miscellaneous part then according to the following relationship formula
D＝3～4d，
L＝3～4d，
D
1＝0.85～0.90D，
d
1＝0.45～0.50d
It is preferably identical with the material of main flow pipeline to make material of the present invention.
