Yuken : Vane Pump



Vane Pump :

Vane pumps are available in a number of vane configurations including sliding vane (left), flexible vane, swinging vane, rolling vane, and external vane. Vane pumps are noted for their dry priming, ease of maintenance, and good suction characteristics over the life of the pump. Moreover, vanes can usually handle fluid temperatures from -32°C / -25°F to 260°C / 500°F and differential pressures to 15 BAR / 200 PSI (higher for hydraulic vane pumps). Each type of vane pump offers unique advantages. For example, external vane pumps can handle large solids.Flexible vane pumps, on the other hand, can only handle small solids but create good vacuum. Sliding vane pumps can run dry for short periods of time and handle small amounts of vapor.





How Vane Pumps Work :

 Despite the different configurations, most vane pumps operate under the same general principle described below.

1. A slotted rotor is eccentrically supported in a cycloidal cam. The rotor is located close to the wall of the cam so a crescent-shaped cavity is formed. The rotor is sealed into the cam by two sideplates. Vanes or blades fit within the slots of the impeller. As the rotor rotates (yellow arrow) and fluid enters the pump, centrifugal force, hydraulic pressure, and/or pushrods push the vanes to the walls of the housing. The tight seal among the vanes, rotor, cam, and sideplate is the key to the good suction characteristics common to the vane pumping principle.
2. The housing and cam force fluid into the pumping chamber through holes in the cam (small red arrow on the bottom of the pump). Fluid enters the pockets created by the vanes, rotor, cam, and sideplate.
3. As the rotor continues around, the vanes sweep the fluid to the opposite side of the crescent where it is squeezed through discharge holes of the cam as the vane approaches the point of the crescent (small red arrow on the side of the pump). Fluid then exits the discharge port.

Yuken Directional Control Valve

Directional Control Valve : Directional Control Valve controls the direction of a fluid in the hydraulic system and pass through. This device is used to redirects or stops the fluid flow with the help of internal machine  in the valve. Valves contain ports that are external openings for fluid to enter and leave via connecting pipelines, The number of ports on a directional control valve (DCV ) is usually to identified  the term “ way”. There are different types of DCV that are classified based on the fluid path:  1)Check valves  2)Shuttle Valves  4)Two-way valves  5)Three way valves  6)Four way valves For further Technical details or Inquiries  mail to  info@jsdgroup.in  or  visit www.jsdgroup.in  some of Yuken regular Directional control valves available  ex stock : DSG-01-2B2-R220-N1-50 DSG-01-2B2-D24-N1-50 DSG-01-2B2-D24-70 DSG-01-2B2-A120-N1-50 DSG-01-2B2-A240-N1-50 DSG-01-2B2-D110-N1-50 DSG-01-2B2-A100-70

Yuken check valve

Image
Check valve : Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal. Technical terminology : Cracking pressure — Refers to the minimum pressure differential needed between the inlet and outlet of the valve at which the first indication of flow occurs (steady stream of bubbles). Cracking pressure is also known as unseating head (pressure) or opening pressure.
