    The gear metering pump can be called either a gear pump or a metering pump, which is specially designed. The manufacture of this kind of pump is made of special materials, coupled with special technology and special equipment, and is a metering device applied to gear pump equipment after special processing. Although this kind of equipment was first used in foreign equipment, after years of development, domestic brands are no worse than foreign brands in terms of machining accuracy and performance.

 

    Working principle of gear metering pump

 

    The working principle of the gear metering pump, the gear metering pump operates through the mutual meshing of the driving gear and the passive gear, and the driving gear drives the meshing rotation. There will be a small gap between the gear and the casing of the pump. When the gear rotates, in the suction chamber where the gear gradually disengages, the closed volume between the teeth will increase to form a partial vacuum effect. Then the liquid will be sucked into the suction chamber under the action of the pressure difference. With the rotation of the gear, the liquid will be pushed forward by the gear in two ways between the gear and the casing, and the liquid will be sent to the discharge chamber. The two gears in the discharge chamber will gradually mesh, the volume will become smaller, and the liquid between the gears will be squeezed to the discharge port.

 

    Features of gear metering pump

 

    The machining accuracy requirements of the gear metering pump are very high, whether it is the accuracy of the tooth surface of the gear, the accuracy of the gear and the casing, and the matching accuracy of the gear and the top of the tooth. Certainly. The device only needs to measure the rotational speed to get the liquid flow. The summary of its characteristics is high precision, which can ensure stable and repeatable flow under various conditions of temperature, viscosity and pressure, and has good repeatability.

 

    The gear metering pump has a very large influence on the overall operation effect of the motor equipment, so in the process of use, it is necessary to pay attention to whether the maximum speed allowed by the pump meets the maximum speed of the actual work, and do not choose to exceed the maximum speed limit. pump to avoid damage to the pump. In addition, it is also necessary to ensure that the fluid enters the inlet under the condition that the rotational speed is within the allowable range, so as to avoid liquid waste caused by the outflow of the fluid. Finally, it should be noted that the material of this kind of pump needs to be maintained frequently. It can be wiped and cleaned with special cleaning and maintenance reagents to avoid collapse caused by rust.
