Abstract
The invention discloses an inlet liquid flow pulsation vibration isolation device for a high pressure plunger water pump. The device is characterized in that: a vibration isolator inlet pipe of a vibration isolator device is connected with a main water supply pipeline; a vibration isolator outlet pipe is connected with the high pressure water pump; when liquid flow flows from the vibration isolator inlet pipe to the vibration isolator device, liquid flow pulsatile impact caused by the high pressure plunger water pump is avoided under the action of a convolutional vibration isolation baffle plate in a vibration isolator; when the pressure of the liquid flow is higher than that of a compression spring, the pressure of the liquid flow acts on a fixing plate in a corrugated diaphragm, so that the compression spring is compressed, the corrugated diaphragm is extended, and the area of an inner accommodating cavity of the vibration isolator is increased; when hydraulic impact in a pipeline disappears and impact pressure is reduced, the corrugated diaphragm is compressed under the action of elastic force of the compression spring in a corrugated diaphragm component, and the area of the inner accommodating cavity of the vibration isolator is reduced; and the hydraulic impact and pulsation in the liquid flow are eliminated through the change of the inner accommodating cavity. The device has a simple structure, is convenient to install, and can effectively avoid the phenomena of the hydraulic impact and the pulsation in the pipeline.
Description
Technical field
Patent of the present invention relates to a kind of high-pressure plunger water pump import fluid pulse isolation mounting; Specifically a kind ofly be used to reduce water supply piping system internal flow fluid pulse, prevent because of the pulsation of pipe interior fluid stream cause as pipe vibration, pressure gauge damage, a kind of water pipe high-pressure water pump import vibration isolator device of pipe joint leaks and pipeline shakes phenomenons such as splitting.
Background technique
For the used high-pressure plunger type water pump in production scene, generally, because the restriction of the used plunger quantity of high-pressure plunger pump, causing high-pressure water pump to export all can be when producing certain high pressure water, with bigger pressure pulsation phenomenon.Simultaneously,, the bigger pulsation of water flow can occur sucking, cause the judder of inlet pipeline at the water intake of high-pressure service pump.At present, generally all be to take certain measure for high-pressure water pump at water outlet, it is moving to suppress pressure pulse.
Usually the method that adopts mainly contains: take measures to make the fluid pulse decay in the high-pressure service pump outlet port, this also is the measure of generally taking at present, and concrete implementation methods has:
1. reduce the pipeline fluid pulse through changing this body structure of high-pressure service pump, this kind method and technology difficulty is bigger, actual performance difficulty.
2. through the decay pressure pulsation of high-pressure service pump outlet of accumulator is installed, come the absorption pressure pulsation through Conversion of energy between energy-accumulating element and the system pressure.This method exists that the energy-accumulating element volume is big, inertia is big, reacts insensitive, and shortcomings such as frictional loss are arranged.
3. through the decay pressure pulsation of high-pressure service pump outlet of attenuator is installed, rely on the acting in conjunction of cavity volume and interior panelling, the eddy current yardstick at the liquid of turbulence state current downflow is diminished, the mobile of fluid tends to balance, thereby makes its pressure pulsation be able to decay.There are shortcomings such as the pressure loss is big, attenuate pulsations weak effect in this method.
Take measures to make the fluid pulse decay in high-pressure water pump inlet, this method is less at present.Generally, reduce the fluid pulse of import through the methods such as water tank of taking to increase caliber, increase pipeline compensator or setting up big volume, but this class methods DeGrain.Moreover, for isolated high-voltage water pump and water inlet main pipe, a pre-pressure pump is installed sometimes in the middle of two, the one, improve the suction condition of high-pressure service pump; The 2nd, keep apart both, though temporarily alleviated this oscillation phenomenon to a certain extent, do not tackle the problem at its root.And, also having increased equipment cost, the bigger pulsation of flow also can cause the destruction of pre-pressure pump.In the production scene, still fail up till now to address this problem preferably.
Summary of the invention
In order to overcome the existing existing defective of method that is used to subdue water supply piping system internal flow fluid pulse, simultaneously simple in structure again, easy for installation, the device that energy consumption is low is solved water supply piping system internal flow fluid pulse phenomenon preferably.
Patent of the present invention provides a kind of simple water pipe high-pressure water pump import vibration isolator device.
Technical problem to be solved by this invention is: the high-pressure plunger water pump import of water pipe directly links to each other with main water supply pipe; Because sucking the hydraulic shock that causes, the gap of high-pressure service pump will be delivered to main water supply pipe; Cause the main water supply pipe vibration; Even fracture etc., directly have influence on carrying out smoothly of production.
The major character that the present invention had is: after installing water pipe high-pressure water pump import vibration isolator device between import of high-pressure plunger water pump and the water supply line additional; The flow flow pulsation that water intake produced at the high-pressure plunger water pump; Under the effect of the vibration isolation baffle plate that unsettled flow is circled round, cut off the direct interaction between import of high-pressure plunger water pump and intake pipe in the middle of vibration isolator; Simultaneously, convolution diaphragm in the convolution diaphragm assembly of vibration isolator device and pressure spring all are elastic elements, all can well play absorbing, slow effect of shaking, and this has also further alleviated inner impact and the pulsation phenomenon of flow.
The invention provides a kind of water pipe high-pressure water pump import vibration isolator device.The vibration isolator device mainly is made up of vibration isolator assembly and convolution diaphragm assembly two-part.The vibration isolator inlet tube of vibration isolator assembly links to each other with main water supply pipe, and the vibration isolator outer pipe links to each other with high-pressure service pump.When flow when the vibration isolator inlet tube flows into the vibration isolator device, through the effect of the vibration isolation baffle plate that circles round in the vibration isolator, the vibration isolator interior flow field can form the eddy current of various sizes, these eddy current collide each other, interact, and fluid pulsation is cut off.The mode that the double-screw bolt of connection vibration isolator assembly and convolution diaphragm assembly is taked to weld links together with the vibration isolator shell, can avoid the leakage of flow from the threaded connection place.In the convolution diaphragm assembly; Convolution diaphragm and pressure spring link together through convolution diaphragm internal fixation plate, convolution diaphragm outer fixing plate, nut and bolt, when flow when the vibration isolator inlet tube flows into vibration isolator device and pressure greater than the pressure of pressure spring, the pressure of flow acts on the convolution diaphragm internal fixation plate; Thereby pressure spring is compressed; The convolution diaphragm elongation, the inner volume of vibration isolator increases, thereby impact of flow internal hydraulic pressure and pulsation are subdued; When liquid flow impact in the pipeline reduces, under the elastic force effect of the pressure spring in the convolution diaphragm assembly, the spring elongation, the convolution diaphragm compression, the vibration isolator inner volume reduces.And the decrement of pressure spring can be regulated through the external bolt in the convolution diaphragm assembly in advance.
This apparatus features is:
(1) this water pipe high-pressure water pump import vibration isolator device is installed in high-pressure service pump inlet, can well alleviate hydraulic shock and pulsation phenomenon in the pipeline, and effect is obvious.
(2) this apparatus structure is simple, and is easy for installation.
