10. Function,Profile/Structure
The FG series hydraulic pump is a backlash compensation internal gear pump with a fixed displacement
Its basic composition is: front cover (1), pump body (2), rear cover (3), gear shaft (4), ringgear (5), sliding bearing (6), front and rear side plates (7) and positioning Rod (8), and the radial compensation function composed of the crescent Sub-Plate(9),the crescent main plate (10)and the plastic rod(11).
11. Oil suction and drainage Process
Hydrodynamically mounted gear shaft (4) rotates the inner teeth in the direction of rotation shown Circle (5).
The oil is inhaled through the tooth side gap that gradually opens in the oil absorption area. Oil passage
The side clearance between the gear shaft and the inner gear ring transmits pressure from the oil absorption area (S) Region (P).Then the inner gear ring is compensated radially, and the oil is discharged and transported through the closedclearance of the tooth side Pressure oil port (P). The oil absorption area and discharge area are provided by radial compensation elements (9,10, 11) and gear shaft between the gear mesh separation.Axial compensation: The discharge chamber in the pressure area is carried out by the front and rear side plates (3) (5) Axial seal. Back pressure of the compression field (13) on the side of the axial seal facing the oil discharge area. These pressure fields balance the radial pressure between the axial sealing ring andtheoil discharge area, thus Achieve the ideal sealing effect with relatively low mechanical loss.
12. Radial compensation
Radial compensation elements include crescent sub-plate (9), crescent motherboard (10) and plastic rod (11)The crescent auxiliary plate (9) and the crescent main board (10) are arranged in the pressure field, so that the pressure generated is basically borne by the positioning rod (8).A small pressure is applied to push the crescent auxiliary plate and the crescent motherboard to the tooth tips of the gear shaft and the inner gear ring, thus separating the oil discharge area from the oil suction area by automatic clearance adjustment. This is a prerequisite for consistently maintaining high volumetric efficiency throughout the working time. The clearance adjustment of the crescent sub-plate and the crescent motherboard can be carried out by means of a plastic rod (11) in the middle.
13.HydrodynamicandHydrostatic Installation
The gear shaft (4) is supported by a hydrodynamic lubricated radial plain bearing (6). Theinner gear ring (5) is installed in the pump body (2) in a hydrostatic manner.
14.Engage
Involute tooth type meshing has long meshing for lower flow andpressure pulsations The length has the advantage of ensuring low noise.
