1、 Product Overview of PBG Vertical Shielded Pump
The PBG vertical shielded pump is composed of a water pump and a shielded electric motor, forming a sealed whole with a static sealing design. Shielded pumps can be widely used in the transportation of non corrosive cold and hot water in heating, sanitary water, and chilled water systems. They are ideal transportation equipment for heat exchange stations and centralized heating pipelines in hotels, hospitals, factories, residences, and other places. Compared with ordinary water pumps, it has the characteristics of compact pump machine integrated structure, small volume, beautiful appearance, smooth operation, easy installation, no noise, zero leakage, etc., which can meet the increasing demand of users for stability and environmental protection in the working environment to the limit.
2、 Characteristics and Applications of PBG Vertical Shielded Pump
Hot water shielded pumps have the characteristics of compact pump machine integrated structure, small volume, beautiful appearance, smooth operation, easy installation, no noise, zero leakage, and no pollution. Widely used in HVAC cold and hot water circulation, industrial and urban water supply, pipeline pressurization, long-distance water delivery and other occasions, derivative products with different materials are more suitable for petroleum, chemical, pharmaceutical, food, refrigeration and other industries. Various occasions including high, low, and high pressure.
3、 Working conditions of PBG vertical shielded pump
1. The rated voltage of the shielded pump power supply is 380V, with a frequency of 50Hz and three-phase AC power;
2. The fluid transported by the hot water shielded pump should not contain solid particles with a volume ratio exceeding 0.1 and a particle size greater than 0.2mm;
3. The temperature of the liquid transported by the hot water shielded pump is 120 degrees Celsius;
4. The pressure of the shielded pump system shall not exceed 1.0MPa and shall not be less than 50Kpa; If it exceeds the limit, please indicate it when placing the order
5. The ambient temperature of the hot water shielded pump shall not exceed 40 ° C, and the altitude of the hot water shielded pump shall not exceed 1000mm
7. The shielded pump motor is of the squirrel cage type and is suitable for full pressure starting. If the original capacity of the motor is insufficient for full pressure starting, voltage reduction starting can be used.
4、 Structure type of PBG vertical shielded pump:
1. Integrated structure of motor and water pump, with the water pump and motor connected coaxially;
2. The inner side of the motor stator and the outer side of the rotor are equipped with shielding sleeves, and the inner side of the shielding sleeve is connected to the inside of the pump;
3. There are two installation methods: horizontal and vertical
4. The motor eliminates the cooling fan and cools the motor through circulating medium between the stator and rotor, while also using surface cooling on the motor base.
5、 Product features:
1. The integrated structure of the motor and pump adopts static sealing, ensuring that the electric pump is completely leak free;
2. Fully enclosed and leak free structure capable of transporting toxic and harmful liquid substances;
3. Adopting a shielded water-cooled motor and eliminating the cooling fan to ensure low-noise and silent operation of the pump, it is suitable for occasions with high environmental noise requirements;
4. Graphite sliding bearings lubricated with conveying media result in lower operating noise and no need for manual oiling, reducing maintenance costs; In recent years, the bearing materials have increased to include silicon carbide (SIC), superhard, etc., with a longer service life than graphite bearings.
5. The vertical structure can be installed on the pipeline like a valve, which is convenient and fast to install. During maintenance, only the motor and impeller need to be removed without dismantling the pipeline.
6. It can be installed and operated in conjunction with shock absorbers or shock pads to reduce the noise of the electric pump during operation.
