Efficient energy-saving marine pump

Abstract

The invention discloses an efficient energy-saving marine pump which comprises a base. A first turbine shell and a second turbine shell are fixedly arranged above the base. The two sides of the firstturbine shell and the second turbine shell are provided with end covers correspondingly, through holes are formed in the middles of the end covers, impellers are arranged in the first turbine shell and the second turbine shell correspondingly, rotating shafts are arranged in the middles of the impellers, the rotating shafts of the impellers inside the first turbine shell and the second turbine shell are connected through an electromagnetic clutch, the rotating shaft of the impeller inside the second turbine shell is connected with an output shaft of a motor through a coupler, and the motor isfixedly installed to the base through a motor installation base. According to the efficient energy-saving marine pump, the water pumping speed is adjusted by adjusting the number of the working impellers, water drainage pressure is improved by adding an energy storage tank, remote ejection is achieved, and energy saving and high efficiency are achieved by adjusting the power of the motor.

Description

technical field [0001] The invention relates to the technical field of mechanical pumps, in particular to a high-efficiency and energy-saving marine pump. Background technique [0002] Marine pumps are mostly used as fire pumps on ships. Because it is more convenient to fetch water at sea, there is generally no water storage tank dedicated to fire fighting on ships, so fire water is directly extracted from seawater. However, most of the existing marine pumps have limited power. Or the power is constant, resulting in limited and unadjustable water outlet pressure, unable to meet the long-distance spray of water column, resulting in limited fire protection effect, so it is necessary to install a booster pump at the water outlet of the marine pump to adjust and pressurize the water outlet pressure. However, adding a booster pump will increase energy consumption, and the efficiency cannot be greatly improved. Contents of the invention [0003] The technical problem to be solv...
