The materials conveyed by the fuel transfer pump are flammable and explosive, so special attention should be paid to the selection and structure of the fuel transfer pump. Today, Shenghui Pumps teaches you how to select the fuel transfer pump.
Fuel transfer pumps are named by the pump industry according to their purpose. What can be used as a fuel transfer pump is not a pump, but a variety of options. For example, gear pumps, screw pumps, and centrifugal pumps can all be used as fuel transfer pumps. Here are some points that should be paid attention to as fuel delivery pumps.
1.When the gear pump is used as a fuel delivery pump, in order to prevent sparks during fuel delivery, copper gears are recommended for over-current parts. Gear pumps use explosion-proof motors to drive the pump shaft to mesh gears. The flow selection is recommended to be greater than the user's flow requirements during model selection. , At least more than 20% of the required flow rate, because the viscosity of the fuel is relatively low, the gear pump will have internal leakage when it is delivered, and the flow rate should leave a part of the surplus.
2.When the screw pump is used as a fuel delivery pump, it is recommended to choose the copper pump casing material, and the bearing should be an external bearing type. The flow rate should also be left a part of the margin, and the motor should be explosion-proof. The centrifugal pump is used as a fuel delivery pump. The default standard configuration is a copper impeller. The centrifugal pump can transport low-viscosity fuel materials such as gasoline and diesel.
3.The centrifugal pump as a fuel delivery pump is different from a positive displacement pump. It transports materials by the centrifugal force of the impeller. The head must be consistent with the user's site head. Remember not to exceed the user's requirements too much, otherwise the flow will exceed a lot, the current will be excessive, and even burn Bad motor.
