The Principle Of Operation And Scope Of Gear Pumps

Gear pumps: principle of operation and scope of application

Gear pumps are a type of hydraulic equipment that work with viscous liquids: from pure water to

bitumen, resins and fuel oil. Due to the robust construction and high performance, the models

pump products evenly. These devices, unlike other types of volumetric rotary models,

have a simple design.

The principle of operation and scope of gear pumps

The models are quite simple, regardless of the type of pump. The main difficulty is the need to

accurately select the parts for the pump, since the space between the parts should be small. The

performance of the equipment depends on which gaps. In addition, if necessary, it may be

necessary to create heat-resistant casings.

The principle of operation is to start the driven gear under the action of the driving gear.

After the engagement, the liquid enters the pressure line under pressure. The connection

of the discharge and suction areas is hermetically sealed. After the transition of the teeth from the

clutch, the liquid passes into the space due to the discharge. The pressure of the gears allows

you to increase the efficiency of work.

The main tasks of gear pumps are:

· transfer of liquids;

· dosage;

· pumping of chemical reagents;

· work in the hydraulic system.
