Description

High solid contains epoxy self-adhesion lacquer gear pump for production

Technical Field

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. When the gear pump works, the driving wheel rotates along with the motor and drives the driven wheel to rotate, when meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, the pressure is reduced, liquid in the suction pipe is sucked into the pump, and the sucked liquid is divided into two paths which are pushed to the discharge chamber by the gear in the tooth grooves. Compared to conventional pump bodies, gear pumps are suitable for conveying relatively viscous liquids, such as lubricating and combustion oils.
