What is the difference between axial piston pump and radial piston pump?
A radial piston pump is a type of hydraulic piston pump. The working pistons extend in a radial direction symmetrically around the shaft, marking the main difference beween them and another piston pump, the axial piston pump, which has axially rotating pistons.
How does a radial piston pump work?
Radial piston pumps work by having an eccentric shaft that pushes radially positioned pistons outward to provide flow, then when they are drawn backward, a valve inside the piston opens to allow new fluid into the piston and stop the pressurised fluid from returning into the piston cavity.
Where is radial piston pump used?
Radial piston pumps are used in applications that involve high pressures (operating pressures above 400 bar and up to 700 bar), such as presses, machines for processing plastic and machine tools that clamp hydraulics.
How do you calculate hydraulic flow?
Multiply the cross-sectional area by the flow velocity, provided in unit of length over unit time squared. If the cross-sectional area and flow are truly perpendicular, the flow rate angle is zero degrees. The value you just calculated is the hydraulic flow.
What is RAM type pump?
DIY hydraulic ram pump. The Hydraulic Ram Pump, Hydram, or simply Ram Pump is an automatic pumping device that is capable of pumping water higher than its original source without using electricity or any other power source. It uses just two moving parts, and it is therefore mechanically very simple.
How do you diagnose a hydraulic pump failure?
Signs of Imminent Pump Failure
- Knocking and banging sounds or unusual vibration.
- Sudden drops in pressure.
- Weak final drive motor.
- Leaking hydraulic fluid.
- Pump seals that repeatedly fail.
- Erratic or weak cylinder operation.
- Abnormally high temperatures while the pump is running.
How do you diagnose a bad hydraulic pump?
Don’t ignore these signs of a failing hydraulic pump.
- Your Hydraulic Pump Makes Noises. Hydraulic pumps make noise as they operate.
- Your Hydraulic Pump Leaks. Any leaking of hydraulic fluids should give you some concern.
- Your Hydraulic Pump Gets Too Hot.
- Your Hydraulic Pump Slows Down.
