Description

Low-noise energy-saving gear pump

Technical Field

The utility model relates to a gear pump technical field specifically is a low noise energy-saving gear pump.

Background

Gear pumps are rotary pumps that deliver or pressurize fluid by virtue of the change in working volume and movement created between a pump cylinder and a meshing gear. Two gears, pump body and front and back covers form two closed spaces, when the gears rotate, the space on the gear disengagement side becomes larger from smaller to larger to form vacuum to suck liquid, and the space on the gear engagement side becomes smaller from larger to smaller to squeeze liquid into the pipeline. The suction chamber and the discharge chamber are separated by a meshing line of two gears. The pressure at the discharge of the gear pump is entirely dependent on the amount of resistance at the pump outlet. When the gear pump works, the driving wheel rotates along with the motor and drives the driven wheel to rotate. When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, the pressure is reduced, and the liquid in the suction pipe is sucked into the pump; the suction liquid is pushed to the discharge chamber by the gear in the tooth grooves in two paths. After the liquid enters the discharge chamber, the teeth of the two gears are engaged continuously, so that the liquid is squeezed and enters the discharge pipe from the discharge chamber. The driving gear and the driven gear are continuously rotated, and the pump can continuously suck and discharge liquid.

At present, the gear pump rotating shaft has large friction resistance, large generated noise and low mechanical transmission efficiency, and causes mechanical energy waste, so that a novel low-noise energy-saving gear pump is urgently needed to be developed in the market.
