pump selection requires many factors like the flow rate requirements, speed , pressure,cost ,maintenance, performance,reliability. step1: find out what type of actuator your are going to use depending on the type of loading .cylinder type actuator or a rotary type actuator like a hydraulic motor.
step2: find out the flow rate requirements depending upon the distance through which the load is to be moved in a specified time limit.
step3: find out the pressure requirements depending upon the magnitude of the load and the size of the actuator.now along with the flow rate you can find the power requirement of the pump and select the prime mover do drive the pump.
step4:find out the speed of the pump and along with flow rate calculations determine the pump size.
step5: gear ,vane and piston are the types of pump available for the fluid power applications.there are many subtypes available for these pumps.
gear pump= 500-3000 psi,1200-2500 rpm,efficiency 80-90 ,flow capacity 1-200 gpm
vane pump=1000-2000 psi,speed 1200-1800 rpm, efficiency 80-95, flow capacity 1-80gpm
piston pump=2000-12000 psi, speed 1200-3000 rpm, efficiency 85-98,flow capacity 1-200 gpm.
apart from these determine the power losses etc.,

∙ 12y agoYou need to know what force your actuator needs to provide and what stroke length - these two factors determine the basic dimensions of the actuator.
You will also need to make sure it is compatible with your hydraulic fluid and hose connections.

What develops the pressure in the hydraulic system?

What are the types of hydraulic actuator?
tie rod cylinders rotary actuators grippers rodless actuators w/ magnetic linkage or rotary cylinders rodless actuator w/ mechanical linkage
What are the Application of control valve with positioner?
One of the application of the control valve with positioner is that it is used to control the opening and closing of the actuator based on electric or pneumatic signals. The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators.
Is hydraulic fluid and hydraulic oil the same thing?
Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.
How is hydraulic system better than pneumatic system with a brief disicussion?
Difficult question to answer without context. Key thing to understand is a pneumatic system uses a compressor, whereas a hydraulic system uses a pump. Hydraulic fluid is essentially incompressible, whereas compressed air will fill any volume. Ask yourself: What is my pneumatic/hydraulic system supposed to do? How fast should it react and what horsepower is available to drive my compressor/pump? What force do I need at my actuator/motor or whatever the system is expected to power? Generally, I think pneumatic systems can react more quickly but power density is lower, so if the load is very high a hydraulic system might be better. A typical shop pneumatic system might only operate at 50psi, whereas a hydraulic system can operate at 3000psi. Finally, it's also worth thinking about system safety: if a pneumatic component fails, there will be an explosive decompression, but if a hydraulic component fails, it will leak but will not explode because hydraulic fluid does not store energy, it only transmits it.
What develops the pressure in the hydraulic system?
actuator
What does the actuator do?
The most common actuator is a hydraulic actuator or an electro-servo actuator. These are linear actuators that move a piston rod to a set stroke and force. It is used to push and pull at a fixed length(stroke) and force. Used in conjuction with rods and cranks, the actuator can be used to move controls through variable geometry such as arcs. The Hydraulic Actuator has a piston internal to the housing. The hydraulic pressure is ported on one end and forces the piston to move to the opposite end, which pushes the rod to extend it. Reversing the hydraulic pressure(or applying it at the other side of the piston) will cause the rod to stroke back to original position. The force that is available is equal to the hydraulic pressure times the area of the piston.
What type of actuators are used in robotics?
There were many types of actuators that are used in robotics, some of which are hydraulic actuator, ultra-piezoelectric, pneumatic actuator and piezoelectric. The actuator is an electromechanical device that converts energy.
What is the difference between a valve and actuator?
actuator is a mechanism that will responds to hydraulic,pneumatic and electrical signal ,it is used to control the valve that to be in open or close condition.
What are the types of hydraulic actuator?
tie rod cylinders rotary actuators grippers rodless actuators w/ magnetic linkage or rotary cylinders rodless actuator w/ mechanical linkage
Where is the fuse for the fan in Lincoln ls 2002?
no fuse... fan is not electric, it's hydraulic... look into fan actuator...
How to select bore for hydraulic cylinder?
depends on the force reuirement.
Where is the fan actuator located on 2001 Lincoln ls?
bottom of fan assy. look for 2 hydraulic hoses going to the fan...
What's the difference in performance between a pneumatic and a hydraulic rotary actuator?
Hydrolic are faster and more powerful. They use comressed air.
What is the weight of a 50ton hydraulic actuator?
The operating pressure is 62.4mpa and the net weight is 31.3kg if the stroke length is 200mm and o.d is 140 mm
A hydraulic actuator can move more precisely than a pneumatic actuator can because?
Don't quote me on this :)Hydraulic actuators work with liquids (usually oil, think hydraulic pistons in earth-moving equipment), pneumatic actuators work with a gas. By definition, a gas is compressible, a liquid is not. In physics, both gasses and liquids can be fluids.In very basic principle, an actuator works by forcing or a fluid into or removing a fluid from one end of a piston and thereby causing either pressure or a vacuum, causing the piston to move out or in, respectively. When the fluid is a gas, the gas will compress or expand a bit before it starts to move the piston and hence the actuator, introducing a lag and imprecision between when the fluid is moved and when the actuator moves. A liquid has a constant volume (it can't be compressed or expanded) and does not have this effect. hence, hydraulic actuators are more precise than pneumatic ones. :)My credibility: 1st year engineering student at UKZN, RSA.

Bobcat loader repair How to fix Bobcat Loader that will not lift or tilt. How to replace the Actuator n a 863H bobcat?
A Bobcat loader that will not lift or tilt probably is low on hydraulic fluid. Check the hydraulic fluid and fill to the recommended level.
