FG10-25-※-01R-VPC-D Double Hydraulic Gear Pump in Harvesters

The FG10-25-※-01R-VPC-D double hydraulic gear pump is specifically designed for use in harvesters, offering

high efficiency and reliability. Its applications in harvesting equipment include:

1. Cutting Mechanism: The pump provides the hydraulic power necessary to operate the cutting blades, ensuring efficient and precise cutting of crops during harvest.

2. Feed Auger Operation: It supplies hydraulic pressure for the feed auger, which transports harvested crops from the cutting platform to the storage area, enhancing the overall throughput of the harvester.

3. Unloading System: The pump powers the unloading system, allowing for quick and efficient transfer of harvested materials into trailers or containers, minimizing downtime.

4. Height Adjustment: The FG10 pump enables the adjustment of the cutting height and angle, allowing operators to adapt to different crop types and field conditions for optimal harvesting.

5. Attachment Control: It also facilitates the operation of various attachments, such as header tilt and steering systems, improving maneuverability and performance in the field.

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.
