Gear pump is mainly used in many chemical and industrial fields of high-end occasions, playing a variety of important roles, such as pressurization, metering, transmission and pumping fluid. In a variety of distillation equipment, such as thin-film evaporator, short-range evaporator or molecular distillation equipment, the efficiency of stable pump is crucial chemical equipment.
“Gear pump”is a rotary pump that mainly depends on the change and movement of the working volume between the pump cylinder and the meshing gear to transport the liquid or to pressurize it. Two closed spaces are composed of two gears, pump body and front and rear cover. When the gear rotates, the volume of the space on the separated side of the gear increases from small to large, forming a vacuum and drawing in the liquid. The volume of the space on the meshing side of the gear decreases from large to small, and squeeze the liquid into the pipe. The suction cavity and the discharge cavity are separated by the meshing lines of the two gears. Gear pump outlet pressure completely depends on the size of the pump outlet resistance.
