The PBG canned motor pump absorbs the advanced technology of the canned motor pump design and manufacture in the world, and applies the motor's shielding technology to the field of fluid transportation. It is the latest series of new products to meet the domestic market demand. The performance parameters of PBG canned pipeline pump series basically meet the requirements of international standard IS02858 and national standard JB / T6878.2-93. With design specifications, high degree of generalization, reasonable structure, stable performance, low noise and no vibration, it is an ideal product to replace conventional horizontal centrifugal pumps and vertical pipeline pumps. The whole series has a total of 67 varieties and 184 specifications, and its performance range: flow 6.3 ～ 1080m3 / h, head 12.5 ～ 125m, equipped with motor power 0.37 ～ 160kW, speed 1450r / min and 2900r / min.
Conditions of Use:
① PBG canned motor pump is used for conveying clean water and other liquids whose physical and chemical properties are similar to clean water. The use temperature of the medium does not exceed 80 ° C, which is suitable for industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other cold and warm water cycle pressurization and equipment matching. It is especially suitable for occasions with high requirements on vibration and noise, such as underground pump rooms and air-conditioning refrigeration systems.
② PBG canned pipeline pump hot water type is mainly used to transport soft water without solid particles at a temperature not exceeding 160 ° C. It is suitable for energy, metallurgy, chemical, textile, papermaking, and hot water pressurization cycles of hotels, restaurants, bathrooms, and boilers. Transmission and urban heating system circulation.
③ PBG canned pipeline pump anti-corrosion type is used to transport liquids without solid particles, corrosive, and viscosity similar to water. It is suitable for petroleum, chemical, metallurgy, power, paper, food, pharmaceutical and synthetic fiber departments.
Structural characteristics and working principle:
1. The canned pump has a compact structure, integrated pump and machine, and small size. Its vertical structure has a small installation area and stable operation, and no adjustment is required for installation.
2. The inlet and outlet of the pump are designed with flanges of the same specifications and located on the same center line, which can be directly installed on the pipeline like a valve, and the center is low, which is convenient for pipeline layout and installation is particularly convenient.
3. The pump is coaxial with the motor, and the axial dimension is short, which makes the pump run more smoothly and the noise is low.
4. The sliding bearing is used to replace the rolling bearing of the conventional motor, so that the pump has a particularly smooth operation and extremely low vibration and noise.
5. Convenient installation and maintenance, no need to dismantle the piping system, as long as the connecting body nut is removed, all the rotor components can be taken out for inspection and maintenance.
6. The series and parallel operation modes of the pump can be performed according to the requirements of use, that is, the flow and head.
