Abstract
The invention provides a centrifugal pump priming device. The centrifugal pump priming device comprises a water filling pipeline connected with a fire protection water tank. The water filling pipeline is provided with a valve. A sealing connection device is arranged at the end, connected with a centrifugal pump, of the water filling pipeline. The water filling pipeline is provided with a check valve. A through pipe part is arranged in the water filling pipeline and close to the centrifugal pump. A one-way flowmeter is arranged in the through pipe part. The water inlet direction of the one-way flowmeter is opposite to the water filling flowing direction. The one-way flowmeter is connected with an alarm device. Water in the fire protection water tank is used for pump priming, so that no extra land needs to be occupied. Besides, when the pump is full, slight backflow occurs in the contact position, the one-way flowmeter carries out counting, an alarm is started, and an operator is informed that the centrifugal pump is full. The centrifugal pump priming device is simple and fast, and the working strength of the operator is relieved.
