Structure Features
VS Vertical Submerged Pump are highly safe, reliable and stable in operation, and have long operation life. The maintenance is easy, and has less categories of spare parts with wide exchangeability.Casing is radial split, and is double volute casing design for flange nominal size 80mm and above so as to reduce radial force and pump vibration caused by hydraulic acting.Fully considered anti-wearing and corrosion resistance for impeller and diffuser so that the life of impeller and other easy worn parts is prolonged. The impeller and diffuser are multi-stage design which can meet various requirement in head.
The axial force is balanced through balancing hole for impeller.The front and rare cover of impeller are equipped with exchangeable special ladder type seals ring to
protect the impeller and pump casing. This effectively avoided foreign matters settling into the seals ring inlet gaps after pump stopping. So the operation life seals
ring and impeller are greatly extended.
Pump shaft is designed for reliable extension-connection type with multi-supporting point, which guaranteed stable operation under critical sevices. The maximum submergence length is 10m.The pump shaft can be protected by tube to avoid wearing or corrosion. And the protection tube is unnecessary when clean water is
handled.
Pump suction is installed filter with proper mesh size which effectively stopped big solids entering and damaging the pump, at the same time ensured net inlet area and reduced suction loss to a maxmum degree, the pump efficiency is increased either.
Pump impeller and casing is submerged under water, so there will not be any problem of draining and venting when pump is starting.
Separate discharge pipe of pump has no pressurized liquid leakage in shaft direction. And if used in open type of system, the shaft seal is no necesssary; If used in close type of system as well as easy volatile or toxic liquid, mechanical seal or packing seal will be available.
Rorating parts can be axially adjusted and are supported with rolling bearings and sliding bearings. The grease lubricated bearing are fitted on the sole plate.
The sliding bearings are self-lubricated or outer lubricated.The self-lubrication structure(flush and lubricate each bearing with pumped liquid from pump discharge,and
then take away the heat produced by friction pair)is suitable to transfer clean liquid without solid. The outer lubrication structure(flush and lubricate each bearing with
outer sourcing clean and pressurized liquid, and then take away heat produced by friction pair, at the same time stop solids or foreign matters from entering the bearing to guarantee the normal operation)suitable for handling pulp liquids with solids or foreign matters.
