The helical gear pump (fig. 4-4) is still another modification of the spur gear pump. Because of the helical gear design, the overlapping of successive…
The herringbone gear pump (fig. 4-3) is a modification of the spur gear pump. The liquid is pumped in the same manner as in the…
The spur gear pump (fig. 4-1) consists of two meshed gears which revolve in a housing. The drive gear in the illustration is turned by…
Piston type motors can be in-line-axis or bent-axis types. (1) In-Line-Axis, Piston-Type Motors. These motors (Figure 4-15) are almost identical to the pumps. They are…
Figure 4-11 shows a vane-type motor. Flow from the pump enters the inlet, forces the rotor and vanes to rotate, and passes out through the…
Figure 4-10 shows a gear-type motor. Both gears are driven gears, but only one is connected to the output shaft. Operation is essentially the reverse…
Hydraulic motors convert hydraulic energy into mechanical energy. In industrial hydraulic circuits, pumps and motors are normally combined with a proper valving and piping to…
a. Overloading. One risk of overloading is the danger of excess torque on a drive shaft. Torque is circular force on an object. An increase…
Piston pumps are either radial or axial. a. Radial. In a radial piston pump (Figure 3-14), the pistons are arranged like wheel spokes in a…
