Double-layer bidirectional flow passage system of vertical submersible axial-flow pump

Abstract

The invention discloses a double-layer bidirectional flow passage system of a vertical submersible axial-flow pump. The double-layer bidirectional flow passage system comprises a support, an upper layer flow passage and a lower layer flow passage; the upper layer flow passage is located above the support; the lower layer flow passage is located below the support; the upper layer flow passage comprises an upper outflow passage and an upper drainage passage; the lower layer flow passage comprises a lower outflow passage and a lower drainage passage; the upper outflow passage and the lower outflow passage are oppositely arranged left and right as well as the upper drainage passage and the lower drainage passage; the middle part of the support is provided with the vertical submersible axial-flow pump; the water inlet side of the vertical submersible axial-flow pump is communicated with the lower layer flow passage; the water outlet side of the vertical submersible axial-flow pump is communicated with the upper layer flow passage; valves are respectively arranged in the upper outflow passage and the upper drainage passage. The invention provides the double-layer bidirectional flow passage system of the vertical submersible axial-flow pump, which is high in reliability, lower in construction cost, high in applicability and high in synchronicity.

Description

technical field [0001] The invention belongs to the fields of municipal administration, farmland water conservancy and chemical liquids, and relates to a double-layer bidirectional channel system of a vertical submersible axial flow pump. Background technique [0002] The vertical axial flow pump is a traditional water pump, and the water part of the factory building must be installed in the civil engineering; lubricating water needs to be injected before starting, cooling water needs to be drawn in the transmission device during operation, ventilation system, oil system, and hoisting equipment are required to protect the motor of the equipment , Monitoring equipment, involving many specialties, unit maintenance and management and maintenance workload is large; the water pump is limited by cavitation conditions, the installation cannot be too high, the motor is limited by moisture-proof and waterproof conditions, and the motor layer is high, so the water pump and the motor ar...
