DL vertical multistage centrifugal pump
DL vertical multistage centrifugal pump (low speed n = 1450 r/min) is to botou haina pump industry co., LTD., based on the actual needs of high-rise building water supply market and national fire GB 6245-1998 standard for fire pump performance requirements and test methods and research and development is a new type of centrifugal pump products.Centrifugal pump for conveying containing no solid particles and physical and chemical properties similar to water medium.Flow range of 5 ~ 360 m3 / h, lift range of 22 ~ 300 m, with range of 1.5 ~ 220 kw power, diameter range from 40 ~ 200 m.The same pump can set 1 ~ 5 export.
Type DL vertical multistage centrifugal pump product features:
Type 1. DL vertical multistage centrifugal pump compact structure, small volume, beautiful appearance, its vertical structure decided to small occupation space for installation, its center of gravity coincidence in the center of pump foot, thus enhancing the running stability and service life of the pump.
2. Type DL vertical multistage centrifugal pump suction and discharge nozzles are horizontal population, which has simplified the connection of pipeline.
3. According to need, suction and discharge nozzles can be installed into the same population or 90 °, 180 °, 270 ° several different direction in order to meet different connection.
4. Type DL vertical multistage centrifugal pump head can be combined according to the need to increase or decrease the pump series and cutting impeller diameter shall be satisfied, without changing the installation area, this is what other pumps.
5. Motor plus cover, pump can be placed in the outdoor use, cancel the pump room, save construction cost.
6. Type DL vertical multistage centrifugal pump rotor with small deflection, and chooses to 4 pole motor, thus smooth operation, little vibration, low noise, long service life.
Type DL vertical multistage centrifugal pump structure details:
Type DL vertical multistage centrifugal pump is composed of two parts of the motor and pump, the motor of Y type three-phase asynchronous motor, pump and motor shaft coupling is used, the overall for the rigid connection, when used without correction.The pump consists of the stator and rotor parts.Pump stator section by section, the water in the middle, guide vane, discharge period, the stuffing box body parts, etc.To prevent wear and tear of the stator, the stator with sealing ring, balance, etc., on the wear and tear after available spare parts for replacement.Rotor part consists of shaft, impeller, balance the hub.Rotor bottom water lubricated bearing, upside for angular contact ball bearings, DL vertical multistage centrifugal pump axial force, for the most part, borne by the balancing drum, and the rest of the small residual axial force of angular contact ball bearings to withstand.Water and water and in combination with surface paper pad by sealing tight to achieve.Shaft seal packing or mechanical seals, the user can choose according to need.
Type DL vertical multistage centrifugal pump rotation direction from the drive end look down for counterclockwise rotation.
1, DL vertical multistage centrifugal pump compact structure, small size, beautiful shape, cover an area of an area small, save construction costs;
2, DL vertical multistage centrifugal pump inlet and outlet in the center of the same line, simplify pipeline connection;
3, according to the actual situation, the import and export of DL vertical multistage centrifugal pump can be assembled into 90 °, 180 °, 270 ° in different directions;
4, according to the actual situation of DL type vertical multistage centrifugal pump outlet can be assembled into 1 ~ 5 export, to meet the same pump head to obtain different;
Type DL vertical multistage centrifugal pump product use:
Type DL vertical multistage centrifugal pump is mainly used in high-rise building water supply, fire control constant pressure water supply, automatic spraying water, automatic water curtain of water supply, etc., can also be used in industrial water supply and drainage, distant distance water, all kinds of used equipment and various production process water, etc.Type DL vertical multistage centrifugal pump medium temperature does not exceed 80 ℃, the DLR type vertical multistage centrifugal pump medium temperature does not exceed 120 ℃.
