What are the characteristics of air conditioning pumps

What are the characteristics of the air-conditioning pump [students’ questions] What are the characteristics of the air-conditioning pump? [Answer] Rear-opening structure, easy repair work is stable, reliable, long-life mechanically sealed low-noise motor, about 10dB lower than similar products, 2.4MPa withstand voltage test is done before leaving the factory, to ensure the use of safe rear-opening structure, easy repair, There is no need to disassemble the pump body and the inlet and outlet pipes. It has wide versatility. It only needs 4 kinds of standard shafts, bearings and coupling covers, which reduces the number of spare parts and is convenient for repairing. There are sealing rings on the front and back of the impeller, and the mechanical seal board of the impeller rear cover The axial force of the balance hole balance pump is a wear-resistant mechanical sealing device to ensure that there is no leakage under high water pressure. The bronze impeller, stainless steel shaft, and imported bearing lubrication are divided into dry grease lubrication and wet mechanical oil lubrication. Use the world’s most excellent mechanical shaft seal planning software and hydraulic model. Use leading vacuum casting skills. The main components are processed by CNC lathes. All impellers have passed the rigorous dynamic balance test. High-quality mechanical seals are selected. A variety of mechanical seals are available. The lubrication equipment is conveniently in place and can be quickly repaired. It is lubricated and reliable. The shortest service life of high-quality double-row thrust ball bearings is 5 years. All cast iron, all bronze, special alloys and other materials are available for selection. The base of the equipment is matched with the motor. The structure has a small footprint, and can be used for straight-line matching in arbitrary directions, and the high-position motor can avoid flooding and other benefits. The pump is a vertical structure with the same inlet and outlet calibers and is located on the same centerline. It can be installed in the pipeline like a valve. It has a compact and beautiful appearance, small footprint, and low construction investment. It can be placed if a protective cover is added. Outdoor use. The impeller is directly equipped on the extended shaft of the motor. The axial size is short and the pump and motor bearings are equipped reasonably. It can effectively balance the radial and axial loads generated by the pump operation, and then ensure the pump's stable operation and low vibration noise. The equipment is easy to repair, no need to dismantle the piping system, just remove the nut of the pump joint base to extract all the rotor parts. The series and parallel working methods of pumps can be selected according to the application needs, that is, the needs of flow and head. The vertical and horizontal equipment of the pump can be selected according to the needs of pipeline installation. The series flow plan is 1.5～1600m3/h, the head plan is 5～125m, and it is divided into various specifications such as base type, split type, and cut type. The above content is compiled based on the questions encountered by the students in the internship work for reference. If you have any questions, please communicate and correct them in time.
