Description
Technical field
The utility model relates to a kind of high-voltage pulse turbulent flow pipeline rinse-system.
Background technology
Hydraulic system generally has conduit under fluid pressure, and particularly field apparatus hydraulic power unit, valve piece and the executing agencies such as large engineering machinery, factory disperse mounting arrangements, between couple together with pipeline.It is very difficult that yet the cleaning of inner-walls of duct is controlled, and the very difficult assurance inwalls such as its site environment, construction method are fully not contaminated, moreover this excessive concern easily has a strong impact on efficiency of construction.So the hydraulic system pipeline all needs to do flushing at on-line execute as last, eliminate foreign object in pipe.
At present pipe flushing generally has two kinds of patterns: 1. self circulation flushing is with conduit under fluid pressure end short circuit, utilizes self hydraulic power unit and valve group to carry out from rinsing.Its effect is not obvious, and pressure or flow generally do not reach requirement, floating thing in pipe can only be washed away, and easily pollution even damages hydraulic valve piece.2. utilize scouring stage to rinse, be will be to be rinsed pipeline be connected on scouring stage and rinse, yet traditional scouring stage is to utilize the fluid that larger oil pump pumps to carry out circulation flushing, the flow of its oil pump is limited, add that flushing can not be equipped with very heavy-duty motor, its pressure is also lower, and is so pipeline inner fluid fluidised form can only be all generally laminar condition, unsatisfactory to the pipe flushing effect.
Hydraulic system abstains from turbulent flow very much, and its reason is that turbulent flow has following feature: 1. fluid motion of point irregular, in the flow field, the value of various flow parameters has pulsation phenomenon.2. due to the sharply blending of pulsation, fluid momentum, energy, temperature and the diffusion rate of concentration that contains thing than laminar flow for large.3. turbulent flow is vortical flows, and has three-dimensional feature.So all formed a kind of prejudice in industry, thought all can not be operated in turbulent condition to all hydraulic system.Simultaneously, the bubble harmful to hydraulic system also avoided as possible.At present also do not have handbook, data to do detailed analysis to pipe flushing, more there is no corresponding technical conditions, the user is nobody's utilization rashly turbulent flow and bubble harmful to system also.
Summary of the invention
The purpose of this utility model is to overcome shortcoming and the prejudice of above-mentioned prior art, and a kind of high-voltage pulse turbulent flow pipeline rinse-system is provided, and overcomes the undesirable problem of hydraulic system pipe flushing.
The cleaning effect that pulse is rinsed far is better than continuous flushing, and the cleaning that is equivalent to attachment waggle formula is rinsed in pulse, and attachment fatigue is come off.Pulse is at present rinsed and is widely used in life, medical domain, but pulse theory does not also apply in cleaning fluid pressing system pipeline process.
Turbulent flow is Reynolds number〉produce when critical Reynolds number (Re〉Re (L)).Reynolds number
(v-pipe in mean flow rate, d-round tube inside diameter, the kinematic viscosity of ν-fluid), when the flushing liquor of the caliber of appointment and appointment, Reynolds numerical value mainly determines by flow rate of liquid and oil temperature, and flow velocity more large Reynold number is larger, and oil molecule up and down play Shaoxing opera is strong.Specify losing along stroke pressure in pipeline
(λ-on-way resistance coefficient, l-duct length, ρ-fluid density) can be reduced to Δ P
T=A ν
2(A-constant) as seen increases flow velocity in pipeline, and its pressure loss becomes the increase of quadratic power, and wanting so to reach turbulent flow also needs enough high pressure except enough flows are arranged.Temperature is higher in addition, and oil viscosity is lower, and Reynolds number is also larger.So the Reynolds number of pipe flushing is mainly determined by flow, pressure and temperature.
Only have pipeline inner fluid fluidised form to reach turbulent condition, oil molecule up and down play adds the cavitation erosion that is mingled with gas, can explode to adhesions such as inner-walls of duct corrosions, corrosivity rinses.
For achieving the above object, the designed a kind of high-voltage pulse turbulent flow pipeline rinse-system of the utility model, it is characterized in that: this system comprises main fuel tank and auxiliary fuel tank, be provided with heater in described main fuel tank, be connected with Oil pump electrical machinery group, pressure sensor, hydraulic control one-way valve between described main fuel tank and auxiliary fuel tank in turn and by the washing pipe road; The described Oil pump electrical machinery group other end is communicated with main fuel tank, and described hydraulic control one-way valve two ends are provided with the magnetic valve of controlling the hydraulic control one-way valve open and close, also are provided with temperature sensor on described main fuel tank, described main fuel tank and between auxiliary fuel tank also be connected with the filter pump group.
Further, also be provided with unloading overflow valve between described Oil pump electrical machinery group and pressure sensor, the described unloading overflow valve other end is communicated with main fuel tank.
Again further, also be provided with the oil suction filter between described main fuel tank and Oil pump electrical machinery group.
Again further, also be provided with fine filter between described Oil pump electrical machinery group and unloading overflow valve.
Again further, also be provided with liquid level sensor on described auxiliary fuel tank.
The utility model has the advantage of:
1, the utility model adopts accumulator, variable displacement with constant power pump, open the valve group with moment, according to the pipeline type requirements, the flushing fluid of high pressure, super-flow can be provided the short time, make the fluid that produces turbulent fluidised form sharply in pipeline, oil molecule forms and bores moving property cleaning at the irregular violent play in up and down.
2, the utility model has a mind to utilize the bubble of circulation generation, and hydraulic system contains the turbulent condition that bubble can aggravate fluid work, and the existence of bubble makes pipeline produce vibration, and it produces cavitation erosion rear the release along tube wall of higher-pressure region compression simultaneously.
3, the utility model adopts pulse to rinse, and can will be attached to the foreign matter that the difficulty of inner-walls of duct goes and carry out the cleaning of waggle formula, makes attachment point tired and come off.
4, the utility model has overcome industry prejudice, adopts pulse and turbulent flow to rinse, and can shorten scavenging period, improve the efficient of rinsing, and flushing is effective.
5, owing to being to adopt in the short time, pipeline is carried out pulse and turbulent mode is rinsed, prove after tested pipeline is not produced any impact.
