Hydraulics

It is a 5 speed manual transmission that is operated/shifted by means of a hydraulic operated clutch.

The equation

Force = pressure x surface of the cylinder

Electric power and torque and power you need to know what you want.

After obtaining the surface area of ​​the circle diameter cylinder, the cylinder can get.

They are both the same thread. They are both calling out a British Parallel Pipe thread. Please do not assume that this is the same as the standard North American pipe thread, as it is not close to the same.

Instead of using wires to model tendons in humans, the use of hydraulics allows better control of force.

faulty lifters at the best will rattle, at the worst they will not lift the valves properly . valves not opening and closing properly will greatly interfere with the proper running of the engine.can also cause a push rod to come loose and fall into the engine, breaking or bending other parts

two types of pump

1- Rotodynamic

2- positivedisplacement

Ohm's Law states that V = IR (voltage = current times resistance). It can be used to find any of those three quantities if the other two are known. It is one of the most important formulae for calculations in electrical circuits - you will use it all the time.

Hydraulic jack oil at auto parts or Wal-Mart store

No, they are not. They are removable, but i do not suggest reusing them. They are hydrolic lifters and have a spring in between them. The following web address you will find them on the page I have posted for you. They are 50% of what napa is asking for them. A really good place to buy engine parts. Your looking at $7 a piece. I would suggest replacing them.

Good luck

The runaway speed of a hydraulic turbine is the speed at which the turbine coupled to the generator runs at the maximum possible speed due to loss of load and this happens until the shut off valves completely closes the discharge from the penstock.

the runaway speed of the turbine is determined by the turbine designer and is influenced by the maximum discharge of water from the penstock, the combined inertia of the turbine runner and the generator and the flywheel.

this factor can vary from 1.5 up to 3 times the nominal speed of the turbine and is determined by the turbine designer considering all the load parameters.

They consist of the hydraulic pressurizing fluid, a prime mover I.e. A pump to pressurize the fluid, transmission pipes, and actuators eg: telescopic hydraulic tubes, to convert pressure energy to mechanical energy

A bourdon tube, typically found in pressure gauges and switches is an oval shaped tube which is then curled lengthwise into an arc. When pressure is applied internally to the tube the natural tendency is for the oval shaped tube to move to form a circular tube, kind of like a balloon does when you blow air into it. Because it is curled when the tube moves towards a circular configuration the shorter inside of the arc lengthens as a result while the outer arc tend to shorten. In other word the tube tries to straighten itself out. When the pressure is removed from the inside of the tube the elasticity of the metal pulls it back into it's original shape. Bourdon tubes are made in different sizes and the smaller dimensioned (the oval not the arc) tubes can carry higher pressures than the larger ones.

Engine oil No. 46 how does this relates to the engine oil type xxWxx?

When a high pressure brake line or power steering line is disconnected near the pistons or any where besides reservoir. air may get into the system. the only way to get the air out of the system is by bleeding system, or purging system. if not done the result will be spongy brake's squealing and whining sounds when turning.

Slippage is oil leaking from a pressure outlet to a low-pressure area or back to an inlet. A drain passage allows leaking oil to return to an inlet or a reservoir. Some slippage is designed into pumps for lubrication purposes. Slippage will increase with pressure and as a pump begins to wear. Oil flow through a given orifice size depends on the pressure drip. An internal leakage path is the same as an orifice. Therefore, if pressure increases, more flow will occur through a leakage path and less from an outlet port. Any increase in slippage is a loss of efficiency.

No, you need to drain and flush the system.

-your device must use hydraulics to exert a large force, using minimal space.

- your hydraulic system must transmit motion smoothly.

-you must be able to operate your device with no breakage of parts.

dumptruck hydraulic pump is filled from a separate tank installed on truck

it is either hanging off chassis rails on side,between dump bed and cab,or it is between rails under neath dump bed. if under dump bed,u can fill with a hose with funnel joined to hose, takes a while to do this . or if truck bed is not loaded you can raise bed with a crane or other machinery ,enuff to get at tank

Loosen the handle to release the jack. remove them fill plug. Pump handle up and down through the full range on motion. Replace plug and test. If it sill does to work satisfactorily, repeat procedure.

The original answer is incorrect (at least in the North American meaning of the term 'Hydraulically smooth'. Hydraulically smooth mean that the roughness on the wall of the pipe is less than 1/2 of the thickness of the viscous sublayer of the turbulent flow. The viscous sublayer is (well) less than 1% of the pipe diameter. The viscous sublayer thickness is calculated as:

t=5D*(8^0.5)/((f^0/5)*Re

where t is the thickness, D is the Diameter, f is the Darcy Friction Factor (found from the Moody Diagram or the Colebrook Equation, and Re is the Reynolds number, based upon pipe diameter and the average flow velocity in the pipe.

Re = u*D/v

u is average velocity

v is kinematic viscosity

As a last comment on the old response, it is in fact describing the critical flow rate for transition to turbulence (i.e. the flow rate for Re ~= 2300). The exact value for transition to turbulence is dicey to determine, and does, as the answer says, depend on the roughness and disturbances. Further, as the equation for Reynolds number shows, the transition to turbulence also depends on diameter. Laminar (not turbulent) flow is often called 'smooth', and the study of fluid motion is hydraulics, so it's easy to get the meaning of 'hydraulically smooth', mixed up with 'smooth (laminar) flow'

*****Old (incorrect) response*****

The flow rate inside a pipe that will produce laminar(No turbulence) flow. The physical smoothness plays a part but need not be as smooth as glass. A concrete, cast iron , copper and glass pipe can all produce laminar flow. The flow rate at which turbulence begins (no longer hydraulically smooth) will depend upon the surface texture where rougher surfaces will cause turbulence to occur at lower flow rates compared to a smoother material. Raise the flow rate enough and your will eventually get turbulence.

So to have hydraulically smooth pipes you would need to spec no only the material but diameter as well to ensure laminar flow up to the max expected flow rate. Also any turbulence inducing fittings would also be included. For example a bar grate in a storm water system could be installed such that hydraulically smooth flow is maintained for low flow rates. (The water ca easily pass around the bars). During the high flows a storm would produce the bar grate would cause a restriction and you would no longer have smooth flow.

If you think about it the hydraulics flowing in the lines are relatively quiet. the piston lifting or lowering the boom is just as quiet...so where is the noise ? it comes from the pump and the prime mover for the pump..If its a diesel engine its loud.. If its steam driven ,somewhere there is a lot of fuel being burned and that location is loud...If its run by an electric motor and Even if its just in the bypass mode the fluid screaming through the control valves will be loud...So now ,,,Going back to your question ..the boom is practically silent but the prime mover makes the whole thing very loud indeed. 90-100db at times...

A leak around the release screw most likely culprit.
