Problems solved by technology

[0002] Most of the existing gear pumps are driven by the direct connection between the main shaft of the pump and the motor through a mechanical seal. The mechanical energy output by the motor is converted into hydraulic energy through the gear. Since the main shaft is directly in contact with the liquid in the pump transmission, the shaft seal Leakage will inevitably occur between them, especially toxic, harmful, volatile, corrosive, and crystalline liquid media, which will cause damage to the environment, and more seriously, cause personal injury; secondly, the alignment between the gear pump and the motor shaft It is difficult to guarantee the stability, which will lead to unbalanced pressure on the gear, pump shaft and bearing, resulting in a large radial load, which limits the increase in pressure, resulting in low working pressure, unstable liquid flow, and relatively pulsation. Large, so that the interface or pipes will vibrate, the noise is particularly loud, and the equipment is easily damaged, which directly affects the normal service life of the pump
[0003] Most of the existing gear pumps are gear oil pumps, which can only barely transport low-pressure and low-temperature (such as about 70°C) oils with self-lubricating liquids. It is difficult to transport the medium normally; in addition, due to the simplicity of the current design and processing and the inability to select the appropriate combination of materials, it is basically impossible to correctly and effectively transport toxic, harmful, volatile, easy to corrode, easy to crystallize, and various harsh chemical media; On the other hand, due to the lack of many aspects such as design, processing and materials, the scope of use is very limited. Its use accuracy, measurement level, cycle efficiency, transmission performance, installation and maintenance are difficult to meet the requirements of current production and life. The wear is very severe, the maintenance is difficult, the use cost is high, and the efficiency of the pump is low, so the service life of the pump is very short, and it cannot be widely and effectively used
