Description
Technical field
The utility model relates to one can reduce hydraulic impulse and impact, and the device of protection oil hydraulic pump, especially can reduce the vibration of hydraulic pressure output duct and the descaling muffler of noise.
Background technique
The oil hydraulic pump of every alternately pumped medium, as plunger pump, gear pump etc., its instantaneous flow exported is all periodic function.Due to the existence of this pulsating flow, corresponding pressure pulsation will be caused in the piping that pump connects.Due to the closed loop that hydraulic system is made up of motor, oil hydraulic pump, valve class, auxiliary device and pipeline etc., in the loop that this is airtight, the hydraulic oil of working state often produces flow noise due to pressure and flow pulsation, then the bracket basis part reaching connection by fluid displacement wall causes vibration and forms the noise that solid structure propagates.Through structural radiation after transmitting, vibration changes air-borne sound into, thus becomes the noise source affecting sensitive point for noise.
Meanwhile, if under the design of pump or piping coordinate irrational situation, fluctuation pressure can reach very large value, may cause mesomerism, causes the fatigue ruption of conduit or element.Meanwhile, if under the design of pump or piping coordinate irrational situation, fluctuation pressure can reach very large value, may cause mesomerism, causes the fatigue ruption of conduit or element.
Summary of the invention
In order to reduce the noise of hydraulic system and eliminate the change of oil hydraulic pump interior oil hydraulic coupling.The utility model provides a kind of descaling muffler, is arranged on hydraulic pressure delivery side of pump, absorption liquid press pump flow and pressure pulsation.
The utility model solves the technological scheme that its technical problem adopts: a kind of descaling muffler, between the import being arranged on hydraulic pressure delivery side of pump and hydraulic pressure output duct, be made up of upper steel pressure pipe, lower steel pressure pipe and steel pressure-resistant conduit, top on the right side of upper steel pressure pipe arranges hydraulic oil outlet joint, middle part on the right side of lower steel pressure pipe arranges hydraulic oil inlet joint, middle part on the left of upper steel pressure pipe, lower steel pressure pipe steel connects steel pressure-resistant conduit, and steel pressure-resistant conduit profile is circular arc.Lower steel pressure pipe and upper steel pressure pipe vertical parallel arrange, and length is consistent, and the internal diameter of lower steel pressure pipe is greater than the internal diameter of steel pressure pipe, and the right side between lower steel pressure pipe and upper steel pressure pipe arranges steel connecting plate.When upper steel pressure pipe, lower steel pressure pipe internal diameter are more than 5 times of steel pressure-resistant conduit internal diameter, near connection part, pressure wave spreads with sphere form.Hydraulic pressure delivery side of pump, upper steel pressure pipe, steel pressure-resistant conduit, lower steel pressure pipe, hydraulic pressure output duct will be separated to form the resonant cavity of similar series connection in descaling muffler.Utilize the expansion of different cross-sectional, volume capacity, contraction, absorb the unbalanced of hydraulic shock and pressure pulsation and flow, make the pressure of output and flow trim, equilibrium, thus reduce structural vibration and the radiated noise of hydraulic system.Use between hydraulic hose connecting fluid pressure delivery side of pump and the hydraulic oil inlet of lower steel pressure pipe, between the hydraulic oil outlet using hydraulic hose to connect upper steel pressure pipe and hydraulic pressure output duct, the internal diameter of steel pressure-resistant conduit, hydraulic hose, hydraulic pressure output duct is consistent.Use hydraulic hose connects, and can slow down oil hydraulic pump vibration and propagate the solid structure of hydraulic pressure output duct.On the right side of lower steel pressure pipe, hydraulic oil inlet joint is female thread structure, and on the right side of upper steel pressure pipe, hydraulic oil outlet joint is female thread structure, and joint all arranges reinforcement structure.Use vibration isolation pipe clamp by rack-mount to upper steel pressure pipe, lower steel pressure pipe, the pedestal of support and oil hydraulic pump is reliably installed.
The beneficial effects of the utility model are, this descaling muffler is arranged between the import of hydraulic pressure delivery side of pump and hydraulic pressure output duct, the Absorbing Fluctuation of hydraulic system can not only be reduced, noise decrease structural vibration and radiated noise, and the fatigue ruption of hydraulic pressure output duct or element can be prevented, structure is simple, easy for installation.
