Gear pump is a rotary pump that transports liquid or pressurizes it according to the change and movement of working volume formed between pump cylinder and meshing gear. The two enclosed spaces are composed of two gears, pump body and front and rear covers. When the gear rotates, the volume of the space on the side of the gear disengaged changes from small to large, forming a vacuum to suck in the liquid. The volume of the space on the meshing side of the gear changes from large to small, and the liquid is squeezed into the pipeline. The suction cavity and the discharge cavity are separated by the meshing line of the two gears. The gear The discharge pressure of the pump depends on the resistance at the pump outlet.

At present, the double gear pump for forklift truck on the market can not be adjusted according to the needs. The single gear pump works alone or at the same time with the double gear pump, and it is not convenient to connect the infusion pipe. When connecting, because it is easy to rotate, the infusion pipe turns to the pipe blockage. Therefore, the relevant technical personnel provide a new type of forklift double gear pump to solve the above technical problems.

The double gear oil pump for the forklift consists of a pump shell, a driving shaft, a screw rod and a rotary joint. A driving gear is arranged on the right side of the pump shell, and the driving gear is connected with the pump shell through the driving shaft. The upper end of the driving shaft passes through the top of the pump shell. The left side of the driving gear is meshed with the driven gear, and the passive gear is connected with the inner wall of the pump shell through the passive shaft The lower end is provided with a gear structure.

The double gear pump used in the forklift can drive the screw rod to rotate by running the rotating rod, so as to control the sliding block to slide up and down, and then control the sliding sleeve to slide up and down, so that the second gear structure is meshed with or separated from the gear structure, so as to adjust the double gear pump used in the forklift to work at the same time or the single gear pump to work alone, which is convenient for users to work according to their needs The applicability of the double gear oil pump for forklift truck is increased by adjusting.
