Hydraulic machines are machines and tools to use
Working ability to flow. Almost all types
Heavy machinery is a common example. This type of
Hydraulic fluid of the equipment is pumped to the utmost
Pressure transmitted from it through the machine
Various actuators.
Engine power for hydraulic pump drive
Motor pressurized liquid is controlled by
The operator with control valve is then dealt
Through the hose and pipe.
The growing popularity of hydraulic machines
Due to the large amount of power transferred
Through small tubes and flexible hoses. High
With power density and a wide range of actuators
Use of this force.
Hydraulic power
There is a theory behind hydraulic equipment
Fluid pressure.
1. Forces acting on small areas,
Can not be evaluated by acting on a large force.
By hydrostatic pressure.
2. A lot of energy can be carried
By very small flow of pressurized liquid.
pump
Hydraulic pump supplies liquid to
A component of the system. Pressure in the system
It develops in response to load. For the pump
Output density
Electric motor. The pump is powered by
An electric motor and an engine
Gear, belt or flexible elastomer coupling
To reduce heavy vibration.
Typical type of hydraulic hydraulic pump
Machine application:
1. Gear pump - gear pump is cheap,
Durable, and easy. It's less effective, simply
Since it is a constant displacement and suitable
Due to pressure below 3,000 psi.
2. Vane pump - Vane pump is cheap and easy,
And reliable. They are a good pump for high flow
Low pressure output.
Hose and pipe
Hydraulic hose will be graded by pressure and temperature,
And liquid compatibility. There is a rubber interior
Multiple layers of woven wire surrounded
The outer surface of rubber hose is designed for
Resistance to wear.
The bending radius of the hydraulic hose is as follows
Ever since carefully designed on machines
Hose failure can be a violation of fatal,
The lowest bending radius of the hose can also occur
It is a failure
The hydraulic pipe is thick enough to have yarn
Cut it for connection. It is rarely used
But because of high pressure system, prefer
Please have a tube or hose. I will lend it to the pipe itself
Welding is also used to manufacture,
Manifold
On the other hand, a hydraulic pipe is preferable
On the hose as much as possible, they are simply
More durable. Tubes are also preferred for tubes,
They are much less heavy. The hydraulic pipe
Flare usually ends, captive nuts
Make the connection. They can also be welded steel
Using Floating Nut and Surface Seal Accessories
Is the end
Both pipes and pipes for hydraulic application
Traditionally not plated or painted,
They operate since temperature and oil
Drive away moisture and reduce the risk of rust.
Fitting
Accessories with hydraulic machinery serve
Some objectives:
1. To different criteria of bride, such
As the boss of the O-ring to the JIC of the pipe or to the thread of the pipe
Face seal
2. Allow proper orientation
Component, as 45 or 90 degrees, straight, or
The accessory of the swing device is selected as it is
Needed. They are designed to be placed
Tighten in the correct orientation
Needed.
3. To incorporate bulkhead hardware.
4. There may be rapid cutting accessories
Added to the machine without changing the hose
Or valves.

How the equipment has changed
There are many different opinions about what
Machines should be classified as Earth
Mobile device. There are many different kinds
Such as equipment corresponding to this category
Excavator, backhoe loader, dump truck, and
Even the loader
The other machine in between is
Tracks, wheels and truck tractors, and more
Scraper thin wire is drawn as usual
Motor grade is more than capacity or lightweight
Duty drilling, although they are mainly used
To level the lot and grade road.
If you take a glance at the literature of any equipment
From leading companies like CAT, Komatsu, or
Case, you will see immediately they believe
The largest and most important change on the last
It is productivity improvement for several years. this is
It is preceded by comfort and safety, which is larger than usual.
Increased productivity,
Many different progress. Cat (Caterpillar)
I quote a faster, more powerful engine
Rise in torque that allows the machine to respond
Faster with the demand for increased power. But
This new generation is much more powerful it
It also has a reduced effect on the environment.
Electron
Most of new machines have electrons
Control system optimizing both engines
And transmission performance, fuel
Consumption and hydraulic equipment performance.
For example, please take the cat's medium size G series
Wheel loader with electronic control
Power shift transmission, each and every
Transmission provides the function of autoshift
Operator pressure, and make it easier
Smooth electronic clutch pressure control
Transfer gear for long life.
comfort
In the industry, excellent operators are getting harder
And it is hard to find. Manufacturers find themselves
By insisting on the comfort and convenience of the operator
Not only need to be taken into account
Easier than work, but more effective
Similarly productive.
The new taxi design has better visibility,
Reduced noise and vibration and improved comfort
Similarly. New control system requires low
Also, while improving control operator effort
As well as machine veterans for both
As an experienced operator.
Easier maintenance
Almost all new machines are electron
Monitoring system providing constant
Information on the health of the machine for
Operator Information on these systems
To the technician, including the service mode it
It is diagnostic condition.
Today, machines are designed to make routines
Maintain easier. Using the cat wheel loader,
Regular service point
Ground condition with the gauge of the place to make it easier,
To check the radiator liquid, hydraulic oil,
And send - without using a dipstick.
Changes for better ones
Compared to today's drilling equipment
On past machines, you will notice it
The change is better. Past machines
As an operator technology relying on
There were very few electronic features.
Today, providing almost all types of heavy machinery
Electronic functions. Electronics is big
They will be able to make an operator's lifespan
Easier than ever. You do not need to get out
Check fluids as everything you need to do
Let's see the instrument panel
It helps to save you a lot of time.
Many experienced operators know first
Hands that past machines can not begin on
I am competing with today's machine. Using technology
Review deleted
What is the future for heavy machinery? Year
From now on, start as much as possible
Heavy equipment will be acquired - and what other features
It makes the life of the operator even easier
That is now.
