Automatic priming device for centrifugal pump

Abstract

The invention discloses an automatic priming device for a centrifugal pump. The automatic priming device mainly comprises a centrifugal pump, a gas-liquid separating tank, a liquid level sensor, a controller, an injector and a valve, wherein the gas-liquid separating tank is connected with a sucking port of the centrifugal pump, the liquid level sensor and a second pneumatic valve; the input of the controller is connected with the liquid level sensor; the output of the controller is connected with an electromagnetic reversing valve; the electromagnetic reserving valve is connected with a first pneumatic valve, the second pneumatic valve and a cut-off valve; and the injector is connected with the second pneumatic valve and is simultaneously connected with the first pneumatic valve through a one-way check valve. According to the automatic priming device disclosed by the invention, the function of automatically priming is achieved and the condition that no cavitation phenomenon always occurs in the operation process of the centrifugal pump can be ensured. In addition, the automatic priming device has the advantages of simple structure, low manufacturing and maintaining cost and stability and reliability in operation and is especially suitable for priming before the start of a ship ballast pump, a bilge pump and an emergency firefighting pump.

AI Technical Summary

Benefits of technology

This patented technology improves upon existing methods by providing an improvement over current systems such as hydraulic dishwashers or air conditioned rooms. It achieves this through improvements made specifically about how the equipment works better than previous designs while still ensuring stability under varying environmental conditions. Additionally, it simplifies manufacture processes and reduces product prices compared to older technologies like electric heat exchangers. Overall, these technical benefits improve efficiency and effectiveness in managing water resources management operations.

Problems solved by technology

The technical problem addressed in this patents relates to improving the efficiency of conventional hydraulic systems used in vehicles like ballasts due to their lack of autonomy (no automated feature). Self-drivable centrifuge pumps offer better functionality without requiring complex equipment. Additionally, they require less space compared to traditional designs while still being able to operate properly even under heavy loads.
