DUAL-ROW GEAR PUMP
The present invention refers to engine power pack is attached to the engine such as internal combustion engine or electric motor number from rotary power transmitted to the required flow rate to hydraulic gear pump generating it sends to spill, steering force required to steel are disclosed. 2 control elements engage one another in this with a general gear pump case is placed within the circle ([...]) rack gear teeth of grooves through the spaces between the wall around is coupled with a pump are disclosed. Disclosure with respect to the registered call patent number 10 - 1413694 corrosion disclosed. Also 1 to 3 also with reference to the function of a gear pump structure and operating principle, first gear pump is formed between bearing housing (1) is installed and, bearing housing (1) one side of decelerator box (2) which is coupled to the, bearing housing (1) the other side of the casing (3) is a connecting. Decelerator box (2) in the motor (not shown.) on axis (4) connected to said motor rotation number 1 and transmits the driving force reduction gear (5) on, not a number 1 to number 1 reduction gear engages shaft reduction gear (5) having a diameter greater than the diameter of number 2 reduction gear (6) are arranged along first is, number 1 reduction gear (5) number 2 on reduction gear (6) are each rotate in opposite directions with each other. Bearing housing (1) in number 1 reduction gear (5) connected to said number 1 on axis reduction gear (5) rotated by gear number 1 (7) to, gear number 1 (7) engages the gear number 1 (7) number 2 rotating along the rotation of the gear (8) is being easily, gear number 1 (7) number 2 on gear (8) are each rotate in opposite directions with each other. Casing (3) number 1 pair of gear (7) connected to gear number 1 on axis (7) of the cylinder number 1 is fixed in a lobe gear impeller (9) on, number 2 gear (8) on port axis with said number 1 lobe gear impeller (9) number 2 engages a gear (8) of the cylinder number 2 is fixed in a lobe gear impeller (10) are arranged along first is, impeller gear lobe number 1 (9) on number 2 lobe gear impeller (10) are each rotate in opposite directions and, number 1, 2 gear impeller (9, 10) rotation fluid transfer with each other. The axis connecting the motor support the shaft axis with rotation of each gear is closely connecting bearing respectively. Gear number 1 (7) to number 1 lobe gear impeller (9) and between said number 2 gear (8) on number 2 lobe gear impeller (10) between hot, to prevent leakage of fluid from the shaft portion under high pressure high speed rotation (mechanical seal) mechanical chamber (11) is connecting. Casing (3) outer casing (3) fluid enters the flow path of the fluid so that, circular inlet holes (13) having an inlet (12) is formed, inlet (12) position opposed sides of a casing (3) outer casing (3) from inside to outside fluid driven by a fluid discharged flow i.e. inclined at, circular holes (15) of air conditioner unit (14) is formed on the, casing (3) for providing the inlet (12) and a discharge section (14) at the end of gun coupled piping (16) respectively in the nanometer range.
