DL(DLR)Vertical Multi-grade pumps for wastewater treatment device

Overview

DL (DLR) type pump suction of multi-stage segmental vertical single centrifugal pump not containing solid particles for conveying water, physical and chemical properties of similar to the use of liquid water. DL, DLR vertical multistage pumps are mainly used to water supply for high buildings, also can be used in water supply and drainage, conveying the factories liquid flow range of 4.9 ~ 200 m3 / h, head of the 22 ~ 239 m range, and the supporting power range of 1.5 ~ 160 KW, diameter scope for 40 to 150 mm.Product useDL (DLR) series vertical multistage centrifugal pump is applicable to industrial and urban water supply and drainage, high-rise building pressurized water, fire pressurization, distance to send water, heating, bathrooms and boilers, hot water circulation pressurization, air conditioning and refrigeration system to send water and equipment supporting and so on. DL type medium using temperature not more than 80 oC, DLR type medium using temperature not more than 120 oCProduct featuresDL (DLR) vertical multistage pumps, compact structure, small volume, beautiful shape, its vertical structure decided to install cover an area of an area small, center of gravity center of pump foot, thus enhanced the pump the operation stability and service life.DL (DLR) vertical multistage suction and discharge nozzles are for horizontal direction, simplified the connection of pipeline.But according to need, the suction and spitting export can be installed into same direction or 90 o, 180 270 o o, several different direction in order to meet different connection occasion.Pump head can according to need to increase or decrease water pump series and combined with cutting impeller diameter, without change to meet cover an area of an area, it is installed other pumps don't have.Plus, the pump motor FangYuZhao can be put in outdoor use, cancel pump room, saves the construction cost.DL (DLR) vertical multistage pump rotor with smaller around the degrees, and chooses to a category four motor, so smooth operation, little vibration, low noise, long service life.Structure thatDL type vertical multistage centrifugal pump by motor and pump two parts, motor as Y three-phase asynchronous motor, the pump and motor shaft coupling, whole is rigid connection, the pump stator and rotor parts. Pump stator in part by the water in the middle section, and diffuser, water section, stuffing box body, etc. Parts. To prevent the stator wear, mounted on the stator sealing rings, balance of spare parts replaced after wearing available. The rotor shaft, partly by the wheel, balance drum etc. Below the rotor for lubrication, the upper bearing for Angle contact ball bearing, the axial pump most of balance drum to undertake, by the axial force a by Angle contact ball bearing to bear. Fill section, middle, and the combination of the water surface for paper pad through the taut to seal. Shaft seals use packing or mechanical seal, user can choose according to need. Pump rotation direction from the driver look down to turn counterclockwise.
