The secondary water supply equipment is widely applied to the fields of water supply transportation of high-rise buildings, water supply pressure supply of districts and the like. The traditional secondary water supply equipment is roughly composed of a water inlet assembly, a water pump set, a water outlet assembly and a control cabinet. In practice it has been found that submersible pumps or pumps in pipe are very quiet in operation. But because of the structure, the submersible pump has high failure rate and is inconvenient to disassemble; although the water-cooling vertical multistage centrifugal pump is silent, tap water is easy to scale and adhere to the inside of a cooling water pipe in the process of internal cooling, heat dissipation is affected, the service life of the water pump is short, and the cost is high. Vertical multistage centrifugal pump, efficient, the fault rate is low, and is longe-lived, and the technology is mature, uses most generally, but this type water pump noise is big, is difficult to satisfy the ambient noise index that constantly promotes. The existing secondary water supply equipment still mostly adopts a vertical multistage centrifugal pump, and in order to overcome the noise problem, a sound insulation measure is mostly adopted in a pump room. It is expensive and difficult to popularize. In addition, pump rooms are mostly arranged in basements, and the basements are flooded by water due to waterlogging, rainstorm, pipe burst and the like; the basement is wet sometimes happens.
