The design of the hydraulic baling press line layout,
As is known to all, hydraulic packer system running well, thestand or fall of mechanical properties, the hydraulic oil
The design ofpipeline system and layout also plays a very important role. So since weare
Have to understand the hydraulic oil or need to know related knowledge offluid kinematics.
In the liquid of fluid mechanics, we know it belongs to thecategory of engineering fluid mechanics,
We applied fluid mechanics researchresults to better known as the hydraulic oil in the hydraulic system
Movementand balance, and related law of interaction between liquid and hydrauliccomponents.
We know that in the fluid mechanics of fluid mechanics is dividedinto hydrostatics and hydrodynamics.
And hydrostatic main research is themechanical law of liquid in the stationary state. The flow
Body dynamicsmainly is the study of the fluid in the movement or flow when the flow velocityand fluid
The pressure change law. We mainly in the hydrostatic is PASCAL'sprinciple
Theory basis to parse the hydrostatic pressure on a pipe or solidwall of the reaction. And in the flow
Dynamics in the us, we will focus onthe liquid in the process of movement on the system and yuan
Brought about bythe loss.
The liquid in the system we know is in the loss of hydraulic presshydraulic oil itself,
Due to its own internal friction, between fluidparticles collide with each other, resulting in the inning
Of liquid flow onthe speed and direction of change, to generate vortex eventually cause thehydraulic oil
And take off the flow phenomenon.
On the study of thehydraulic system loss we have to focus on its two outside itself
So importantloss for our customers in the choose and buy and hydraulic system design
Agood reference.
1. The hydraulic oil pipe in the pipe system and componentsof local damage.
Due to liquid through local port due to the size of theliquid velocity and the direction is changed,
Easy to produce in local vortexseparation flow phenomenon. Thus easy to cause the hydraulic oil in thepipeline
In the turbulent flow.
2. The frictional pressure loss, due tothe fluid within the equivalent pipeline along the flow direction of eachprocess
Between the internal friction and the pressure loss in pressure lossalong the main with us
In the design of the length of the pipeline, pipediameter, the size of the liquid velocity and fluid viscosity
Has a veryclose relationship. So research and analysis to know in the hydraulic system ofhydraulic oil major losses or its total
Loss of frictional pressure loss andall local pressure loss and the piping system in the system Of the "three lossand humanity".
So that we know, in the process of our hydraulic systemrunning and circulation
We want to know:
1. We want to appropriate limittraffic, because the greater the flow the loss caused by the generalassembly.
2. The pipe length as short as possible, so to reduce unnecessarypipe length of liquid pressure loss
Has a direct significance.
3. Becausethe pipe diameter and flow velocity of pipeline is related, so in some flowconditions,
The smaller pipe diameter, the greater the flow velocity, so thevelocity to the proper limits is to reduce the pressure loss of weight To beone of the measures.
