Hydraulics

there are three basic means of power transmission

mechanical

electrical and

fluid power

All these three are power transmission mediums

mechanical - short distance very advantageous.

electrical - long distance eg: hundreds of kilometres of electric grids.

hydraulics - greater distance than the mechanical and shorter than the electrical

They mostly substitute the mechanical power transmitters.

Here there are no moving links as in mechanical medium only moving medium that is fluid.

very high force multiplication possible.

only fluid power capable of giving constant force or torque output at various speeds.

they have very high power to weight ratio than there mechanical counterparts.

a simple, compact, reliable, safe system possible only with fluid power.

their control is very simple.

oil is used in industrial hydraulic system because

there is a fill point on the cylinder itself, the manual says to keep in an upright position but i just did it on the ground. i thought at first it was either the flat-head cap or the hex-key but those are NOT it!! those are adjustments and the hex-key contains ball-bearings!! (if you have happened to take them off and tip it sideways and the bearings fall out, the smaller bearing goes in first ;) lol ) I also found it easier to put the handle back in, with the jack all the way lowered let the handle drop to the ground, on the cylinder you will see a little "hump", that is the fill spot, it's just a rubber plug painted silver to match the jack. i used a flat-head to pop it off, i just guessed on how much to put in, i think i added a quarter qt bottle, otherwise put the plug back in and test it after adding so much at a time.

(note, it will still jack slow if there is no load (weight) on it, also if it jacks up fine but takes a long time to release or go down, that's a sign of "over-filling"- try to avoid that and empty some out if that happens)

n electrical regulator by using resistance the output voltage is varied simultaneously the speed is varied... But to reduce the the energy loses in the resistor, electronic regulator is introduced,which uses triac to vary the output voltage by varying the firing angle.Which avoids lose of energy in resistor...

There is no such thing as "hydraulic cylinder jacks". Hydraulic cylinder is different from hydraulic jacks.

A hydraulic cylinder is a linear actuator used for converting fluid energy to an output force in a linear direction for performing various jobs. These include: pulling or pushing in engineering applications such as in machine tools, earth moving equipments, construction equipments and space applications.

Jacks are portable devices used for raising heavy objects by means of force applied with a lever or screw. The hydraulic jacks are compact and lightweight units that are used for lifting capacities. They offer easy operation and are fast acting components. The hydraulic jacks come with inbuilt release pedal for rapid lowering and lugs that make it easy to mount. The heavy duty chassis prevents the jack from twisting or bending and foot pump provides fast lift to the load. It also has a safety overload valve that prevents overloading beyond rated capacity.

Elevator Counterweight = Half of Elevator Maximum Capacity + Cab Weight

For eg: 10passenger Elevator = 10*80 = 800Kgs

Counter Weight is 800/2 = 400Kgs + Cab Weight

This is just to create a imbalance between Elevator cab and counterweight in order to save power in the drive.

Hi . I am s.g.hegde

as a safer side working max. 600 bar depending upon hyd. Pump capacity available with you.

Turbulent viscosity is a value which is assumed to be equal in all directions.

It is the same as Eddy Viscosity

This is a measure of a fluid which is being deformed by stress. The fact that it is turbulent just means it is changing so the internal friction or viscosity is changing constantly and this is why it is called turbulent. the internal friction is the friction within the object hence the term internal however this friction derives from the force of the fluid acting on the object. E.G if air is your fluid surrounding the object and the object is experiencing a change in the velocity of the air it will be exposed to a different amount of stress and will therefore have a different value for internal friction.

One recalls reading somewhere ( World Alamanac?) that the Montgolfier brothers- better known as Balloon inventors, devised a ( Hydraulic Ram) that was something like an inverted siphon, and at least a forerunner of the hydraulic press.This would have been in the eighteenth century, about the time of ( and it was a lengthy one, Benjamin Franklin). The Montgolfiers were French. Name has nothing to do with Golf.

I believe there is no adjustment to a hydrolic clutch. It is self adjusting. The fluid level in the reservoir may drop, like brake fluid, but other than that...

You can bleed the clutch slave cylinder if it is spongy, with the same method as a brake line. The geniuses at Ford placed a gargantuan version of the bane of all not-brand-new hydrolic lines - the bleeder valve - that ferrets it way to within a fraction of an inch of the main gear box output shaft. It's around a 12mmish 7/16ish hex shaped hollow tube looking thing above the hydrolic line connection to the driver side of the gear box, forward of the shifter, before the bell.

Here's the joy of genius... don't over tighten, cause that's a one-way ticket to dropping an afternoon and your transmission. BS, BS, BS!!

www.hasport.com has clutch master cylinder adapters. Here is the info from their page: "The new master cylinder adapter allows the use of a Honda-style or Wilwood clutch master cylinder to convert a cable transmission vehicle to a hydraulic setup."

Yes it does.

Which are you referring to? Brakes or manual transmission slave cylinder?

Either way, you need to find the bleeder. You will more than likely need a second person to help you.

Get a manual on the vehicle for more details.

The Reynolds number is the relationship between inertial forces (numerator) and viscious forces (demoninator).

The terms in the numerator are usually the fluid density, velocity, and "characteristic" dimension (which has units of length).

Depending on the type of problem you are trying to solve that characteristic dimension may be a length (flat plate problem) or a diameter (flow in a round tube), or hydraulic diameter (non-circular internal flow).

Since a non-circular cross section has more surface area than a circular cross section area there needs to be a way to account for this difference.

If you use the hydraulic diameter equation to calculate the hy. dia. of a circular cross section, you will get the diameter of the circle.

According to the 2003 Ford F-150 Owner Guide :

The clutch fluid ( and brake fluid ) is DOT 3 brake fluid meeting Ford
